Chapter 420 Team Stone Joins the Group
Zhou Yi woke up in a daze and saw Lu Xiaoshuang in pajamas beside him.
"How did I fall asleep..."
"I must be too tired." Lu Xiaoshuang said with a smile.
"Xiao Shuang, how long have I been sleeping?"
"About half an hour."
Zhou Yi sat up and found that he was covered with a folded corner of the quilt.
"No, I have to go."
The file search has not yielded any results yet, and I've been away for so long.
"By the way, Xiao Shuang."
"Don't worry, I won't run around. I've never lived in such a nice house in my life." Lu Xiaoshuang smiled sweetly, "You don't have to worry about me."
Zhou Yi nodded: "If you have any needs, you can always tell Mr. Qian and his wife. Don't hesitate, they are trustworthy."
"Okay." Although she called Qian Hongxing uncle and Yao Yuling sister at first, Lu Xiaoshuang soon realized that they were husband and wife.
"By the way, Brother Zhou, can you help me go to my grandma's house and tell her that I'm okay? It's been so long, I'm afraid she'll be worried."
Zhou Yi thought about it and agreed. Although Lu Xiaoshuang's two uncles and their families were not good to her, they were not good people either.
But that's just a moral issue.
From a legal perspective, the task force in both the previous and current lives has investigated and these people have nothing to do with the case.
Lu Xiaoshuang has been released now, and we must at least tell her grandmother, otherwise who knows how anxious the old lady will be.
"Don't worry, I'll go there in a moment and then come back to the bureau."
"Oh, there's one more thing. Although Sister Qiao has asked enough questions before, you were drugged after all, which may have affected your memory. If you remember any clues later, you must tell me immediately. Mr. Qian has a phone number at home."
Lu Xiaoshuang nodded.
"It doesn't matter if it's a very small detail, it doesn't matter if you're not absolutely sure, because it might be crucial," Zhou Yi emphasized.
"Brother Zhou..." Lu Xiaoshuang hesitated, "Actually... last time when we were having Western food, you asked me that question. There's something I forgot to tell you..."
…
After leaving Hongcheng Baodi, Zhou Yi first went to the Lu family's compound.
In front of the old lady, he called Qian Hongxing's home and let the grandfather and grandson talk on the phone.
Hearing her granddaughter's voice, the old lady finally felt reassured.
She said that the police came several times in the past few days and kept questioning her second son and youngest son's families. Her hearing was poor and she could not hear clearly what they were asking.
Now that she knew her granddaughter was fine, she felt relieved.
After leaving the slum, Zhou Yi drove back to the task force.
All the way, I was thinking about the person Lu Xiaoshuang mentioned, Zheng Jianxin.
Lu Xiaoshuang said that on the night when the school organized a group to watch the episode of "Questioning the Heart" with Zhou Yi, when she came out of the lecture hall, Zheng Jianxin, a male classmate of hers in the same major, gave her a love letter in the name of returning a book.
She refused at that time and returned the love letter to the other party without even opening it.
Since then, Zheng Jianxin never looked for her again, and even avoided her when he saw her.
That day while having Western food, when Zhou Yi asked her about relationship issues, her first reaction was that Zhou Yi was interested in her, so that was why he cared so much.
She didn't mention Zheng Jianxin's matter. After all, it was just a very small episode.
When she was in high school, someone wrote her a love letter and secretly put it in her desk. However, at that time she was only thinking about studying. She didn't read the love letter, but used the back of the letter as draft paper.
Later, when she was working part-time, besides the fat foreman at the Good Luck Restaurant, there were also some normal people who wanted to pursue her, but they all ended in failure because she pretended to be stupid and didn't respond.
She didn't want to make Zhou Yi feel bad because of such a trivial matter, so she didn't say anything.
However, these days, lying on the iron bed in the detention room of the Public Security Bureau, she recalled what had happened and realized that something was wrong.
Zhou Yi's special concern for his own safety from the very beginning, the questions raised during the meal, and Zhou Yi's repeated emphasis on "waiting until everything is calm."
She realized that Zhou Yi seemed to have known from the very beginning that danger was approaching him.
That's why she asked that question in the car.
But after she said that, she regretted it, because she believed in Zhou Yi, no matter what the reason, she believed in him.
Hence the following sentence.
Then she remembered Zheng Jianxin's confession to her, because Zhou Yi had mentioned it, even the smallest detail.
For Zhou Yi, this clue was both surprising and a little embarrassing.
The reason for the surprise was that in the previous life's investigation, the task force did not discover that Zheng Jianxin had a crush on Lu Xiaoshuang.
According to the case in the previous life, anyone who has a secret crush on Lu Xiaoshuang will undoubtedly be the key suspect.
But this is not recorded in the task force's records, so there are two possibilities.
First, Zheng Jianxin did not confess his feelings in the previous life, but this possibility is relatively small.
Second, Zheng Jianxin was rejected by Lu Xiaoshuang in his previous life, just like in this life, so no one knew about this.
However, what is certain is that Zheng Jianxin hid his secret love for Lu Xiaoshuang very well, and no one knew about it except the two parties themselves.
This kind of mentality does indeed lead to the possibility of a criminal mentality of not being able to get the love that is desired and then turning love into hatred.
But the embarrassing thing is that Zheng Jianxin, as one of the few male classmates in the same major as Lu Xiaoshuang, was originally on the core investigation scope list.
And everyone on this list had a clear and verifiable alibi in their previous life.
So far in this life, no suspicious targets have appeared, which means that these people, like in the previous life, have alibis, thus eliminating suspicion.
However, since Lu Xiaoshuang herself provided the clues, we still have to investigate.
When they returned to the task force, everyone saw him yawning.
On the contrary, he may have had a deep sleep for half an hour at Qian Hongxing's house and is in good spirits now.
"Brother Yan, is there any progress?" Zhou Yi asked when he saw Chen Yan.
Chen Yan shook his head wearily: "I'm going to wash my face first and refresh myself..."
"Okay, then I'll go find out some information first. Wait for me, and we'll do something else later."
Zhou Yi first went to find Xiang Jie, then went to the internal affairs team to look through the previous investigation progress records, and finally met Brother Biao.
Quickly understand and sort out the current progress of the case investigation.
Because of the grand case in this life, although there are some clues and directions, the complexity of the case has increased sharply, making the information even more confusing.
First, some progress in the investigation into Xiao Bing.
The first thing was that Xiang Jie said that around 8:40 last night, a policeman who was patrolling near the long-distance bus station found a suspicious person and suspected it was Xiao Bing.
After being discovered, this person immediately fled. Because it was too dark, the police disappeared halfway through chasing him.
The police stationed near the station immediately launched a search, but they did not find any trace of Xiao Bing until dawn.
Xiang Jie explained that, logically, every nearby area had patrol officers. After the man was lost, the police immediately reported it via radio, and a search was quickly launched.
But I just couldn't find this person.
If Xiao Bing did not have a motor vehicle as a means of transportation, then it could only be attributed to Xiao Bing's good luck, as he temporarily stopped a taxi or an illegal motorcycle and escaped before the surrounding area was blocked.
We are currently checking taxis and illegal motorcycle taxis near the train station.
The second thing is about the Xinhua Bookstore near Xiao Bing’s home.
After looking at Xiao Bing's photo, the clerk confirmed that he was a regular customer of the bookstore and came to buy books almost every month.
As for whether Xiao Bing came to the bookstore to buy books on May 1st, it is not certain, because the bookstore was very busy that day and the staff were quite busy.
However, after the police showed the book "Digital Survival" to the bookstore, they confirmed that the book was indeed sold by them and it was even stamped.
However, the exact date of sale cannot be found because there is no sales record.
But one of the shop assistants discovered a detail: the printing batch of this book was different from what is sold in bookstores now.
Because best-selling books sell well, they will be reprinted continuously, and there will be differences in printing batches when bookstores purchase them.
It just so happens that this batch of books only arrived on April 29th.
In other words, it was impossible for Xiao Bing to go to the bookstore on May 1st. He lied.
As for the purpose of lying, it must be to cover up his whereabouts on May 1st. So where did he go and what did he do that day?
I'm afraid we can only know the truth after we catch Xiao Bing and interrogate him.
Then there is the investigation into Xu Liu.
Routine investigations are still ongoing, following a similar trajectory to the previous life. The difficulty lies not in the individual questions asked, but in the verification and confirmation of the information after the questions are asked.
There was already a shortage of manpower, and new clues kept popping up, so we could only rob Peter to repair Paul.
The investigation into Xu Liu is now mainly focused on two directions.
First, the man who provided financial support to Xu Liu.
The investigation into this matter was divided into two groups.
The group went to Xu Liu's hometown, Huaixing, and asked the local police to cooperate in investigating clues about Xu Liu going to the city to work after the college entrance examination.
Since Xu Liu no longer had to worry about living expenses when she started college, it is seriously suspected that she met this man during that summer vacation.
Another person conducted an occupancy registration investigation on all hotels and guesthouses in Qingshan District and Nanming District of Hongcheng. If the man was not a local, then he came to Hongcheng to find Xu Liu, and the two must have had a tryst in a hotel.
Xu Liu's roommates also revealed that during her first semester, Xu Liu would stay out of the dorm for one weekend every three to four weeks. Someone once casually asked her about this, and she replied that she'd been taking a short trip nearby. Others, however, dismissed the idea, knowing that Xu Liu came from a well-off family.
After hearing this, Zhou Yi thought to himself, what a pity there is no WeChat Moments these days. If there were, he would probably have stolen a bunch of pictures from WeChat Moments to create an elaborate persona.
This visiting work is also very tiring, because in this kind of affair, the woman is likely not to register. The man will book the room first, and the woman can go in directly after a while.
So they had to ask repeatedly with Xu Liu's photo, not only the front desk but also the room cleaning staff. The task force was afraid that if they missed someone, they would not be able to find her later.
At the same time, the task force also investigated in another direction.
Based on the fact that Xu Liu asked for leave on the 29th and 30th, we focused on investigating those teachers and students at Hongda who also asked for leave on these two days.
Because according to normal logic, Xu Liu asked for leave from the counselor on the pretext that his family was sick and hospitalized. It is very likely that he wanted to go on vacation with his lover, after all, there are three days of May Day holiday.
If anyone takes leave, we will conduct a focused investigation.
However, there is a loophole here. The nature of the work of teachers above the associate professor level in the school is relatively flexible. Because, in addition to teaching tasks, associate professors and above also have scientific research work, academic exchanges and reviews, etc., and have a high degree of autonomy in their time.
Therefore, we can only judge by the actual implementation of the class schedule. At least so far, no targets with abnormal behavior have been found, especially several male teachers of Xu Liu. They basically followed the class schedule during the day on the 29th and 30th and attended classes on time.
The second direction is the pager provided by Zhou Yixin.
Since Ni Jianrong had given the order personally, his direct subordinates naturally took it to heart, so they were checking the attendance records of various club activities and lectures in the school.
Zhou Yi went to the internal affairs team and asked Director Wang, the person in charge, for the investigation records on Zheng Jianxin.
The clerical team is basically composed of elite backbones selected by Director Wang from the command center, and he leads the team personally.
In the office of the internal affairs team, documents were piled up like mountains. Director Wang sat there, flipping through the file bags one by one.
Each file bag has a corresponding name written on it.
"Liu Changyong, Zhao Qian, Fan Tianyou..." Director Wang shook his head, "No, these are all teachers'."
Turning to look through another pile, he said, "Yes, this one belongs to the male students. Liu Yan... Guo Peng... Zheng Jianxin..."
"Got it. It's here." He handed the file bag to Zhou Yi.
Zhou Yi opened it and took a look. It mainly contained signed confessions from the interrogation, as well as some records of subsequent investigation and verification.
Director Wang adjusted his glasses and said, "As for Zheng Jianxin, I remember Xiao Qiao verified his alibi for the time period of the crime. What's the problem?"
Zhou Yi flipped through Zheng Jianxin's confession and replied casually, "Some new clues have emerged. I need to learn more about this person. Director Wang, can I take this first?"
"Sure, but if you ask Zheng Jianxin to take your statement again, you must follow the rules, sign and seal it, and then bring it back to me for verification and filing."
Zhou Yi nodded: "I understand, thank you Director Wang."
Sure enough, in Zheng Jianxin’s confessions in both his previous life and this life, he did not mention that he had a crush on Lu Xiaoshuang and sent her love letters.
It seems necessary to ask.
Coming out of the office team, Zhou Yi saw a figure in the corridor and waved, "Captain Shi."
Shi Tao was about to turn and go downstairs, but when he turned around and saw Zhou Yi, he stopped.
Zhou Yi trotted over to Shi Tao and asked, "Captain Shi, why are you here?"
Shi Tao sighed helplessly: "Hey, Captain Ni said they are really short of manpower and asked me to join the task force."
"That's great. Captain Ni is right. The task force is very busy right now. Captain Shi, as the leader of the bureau, you have to lead by example and set an example for us." Zhou Yi joked.
Shi Tao lowered his voice and said, "It's just that you are young and energetic and don't understand the reasoning behind this."
"What...what's the reason?" Zhou Yi asked doubtfully.
Shi Tao looked around to see if there was anyone around, and whispered, "This kind of case, which involves so many aspects, is very troublesome. Even if we handle it well, we won't get any benefits. After all, there are so many leaders above us, and the credit will never be ours. At most, we can get some collective honor. But if we don't handle it well... hmph, everyone will be in trouble."
Zhou Yixin said, as expected, it is still Shitao's classic style.
But Shi Tao's next words made Zhou Yi feel nervous.
"I saw this happen ten years ago."
Ten years ago, the task force? Could Shi Tao be referring to the July 27 shooting incident?
"Captain Shi, what was the case ten years ago?" Zhou Yi asked tentatively.
"That's it..." Shi Tao was about to say, but suddenly shut up.
Then he waved his hand and said, "Hey, you were only a few years old at that time. It's old history and has nothing to do with you."
Regardless of whether Shi Tao was pretending to be stupid and changing the subject, there was no way to ask about this matter anymore.
Further questioning will easily arouse suspicion.
"Captain Shi, what will you be responsible for next?"
"It's about the witness investigation in Xinbei Town and the exploration of the mine that your Captain Wu was in charge of."
"Oh, that hasn't progressed yet?"
Shi Tao said helplessly, "What progress have we made? After Old Wu was suspended...sick...sick leave, this matter has been delayed. All the people behind him were pulled away to catch that Xiao Bing."
Zhou Yi sighed. It had been several days since Captain Wu left the task force. It seemed like there was some progress in the case, but in reality, it didn't feel like there was any. It was frustrating.
"So, Captain Shi, do you have anyone available now?"
Shi Tao scratched his head and said, "There's no one here. Lao Gu and I will just go door to door asking. He Bin and the others are still out searching for Xiao Bing. Oh, you reminded me. I still have to ask Lao Qiu for two more people. Lao Gu and I can't go down into this mine."
"Hasn't the mine been surveyed?" Zhou Yi felt strange.
"That's what I thought. We've already surveyed it, so why do we need to investigate further? But I called your Captain Wu this morning. I wanted to ask him about the previous situation, but he told me that the mine still needed to be investigated."
Shi Tao said that what Wu Yongcheng meant was that he had learned about the situation through the local town government in the early stage and learned that these abandoned mines were mined illegally, so the underground structure was very messy and complicated, and many mines were connected.
Therefore, a comprehensive survey is basically impossible.
So during the first investigation, after discovering the human head and the murder weapon, they only continued to search deeper for a distance. After finding no other traces, they retreated and sealed the entrance.
"But Old Wu told me today that he thinks the mine needs further investigation. He said he's figured out that if they continue to dig deeper and find no traces, it doesn't mean there are no traces, because the mine itself is not a straight line."
Zhou Yi immediately understood what Wu Yongcheng meant: "Captain Wu, are you saying that the hole where Lu Xiaoshuang was found might not be the hole where the murderer dumped the body?"
When Shi Tao heard this, his eyes widened in surprise: "Did Old Wu tell you?"
"No, I guessed. Captain Wu probably doesn't mean to continue searching the original cave entrance, but to look for other mine entrances that may be connected internally, right?"
Shi Tao nodded repeatedly: "Yes, yes, that's right, that's what he said. Good fellow, you and your Captain Wu have special abilities, you two think exactly the same thing."
Zhou Yi had never been to Xinbei Town, let alone seen the mine site. At most, he had read the on-site investigation materials after joining the task force.
Shi Tao just relayed Wu Yongcheng's words and enlightened him.
There is indeed a possibility that the cave where the body was thrown and the cave where it was discovered are not the same.
Because there are several suspicious points.
The first thing they did was to rescue Lu Xiaoshuang from the cave. A child who went to pick up coal slag heard the cry for help from the cave.
That means the location of the cave entrance is not particularly remote. Judging from the photos taken during the on-site investigation, the terrain near the mine is relatively flat, without any weeds or being particularly barren.
Otherwise, children would not dare to run and pick up coal slag.
However, this kind of surrounding environment is actually not suitable for such obvious corpse disposal behavior.
Because the surrounding field of vision is relatively wide, it is very easy to be exposed.
Secondly, on-site investigation outside the mine did not find any vehicle tire marks nearby.
If the footprints in the mine could be deliberately erased through careful inspection, it would be understandable and consistent with the murderer's cautious character.
It is unbelievable that the traces left by the car were also erased artificially.
It's impossible for the murderer to get out of the car and clean up the traces every time he drives a certain distance?
Again, such bizarre behavior is very easy to expose and forms a characteristic memory of the witness.
Finally, on the night he returned to Hongcheng, at Wu Yongcheng's home, when he mentioned the exploration of the mine, he emphasized the problems of illegal mining and internal connectivity in the mine.
Zhou Yi was not sure whether Wu Yongcheng had already begun to suspect at that time that the murderer might have dumped the body through other holes.
But at that time, Zhou Yi's mind was full of trying to figure out why Lu Xiaoshuang became a criminal suspect, so he didn't notice this.
Looking back now, Captain Wu is truly a veteran.
Unfortunately, he made sacrifices in order to get himself into the task force.
But Zhou Yi didn’t understand why Wu Yongcheng didn’t express his suspicions at the time?
Do you think you will definitely find out?
Suddenly, Zhou Yi felt his face getting hot because he felt a little ashamed.
It was only after Shi Tao took over that Wu Yongcheng pointed out the problem.
I wonder if Captain Wu feels disappointed...
This reminded Zhou Yi of another detail. Wu Yongcheng mentioned that after the coal mines in Xinbei Town were exhausted, the local government had no money to fill the landfill, so they could only block the holes with wooden boards.
But some people even steal this kind of wooden board, which causes some holes to be directly exposed.
From the murderer's perspective, a cave entrance that is in a remote location and where no one passes by is the first choice because it has a high safety factor.
Then, compared to the hole without wooden boards, Zhou Yi preferred the hole with wooden boards because it was less likely to arouse suspicion.
However, this kind of wooden board sealing hole is usually done by using horizontal wood to clamp the four sides to form a frame, and then laying wooden boards on it and nailing it shut.
Although it is very difficult to take it apart, it is less likely to arouse suspicion from others afterwards, so Zhou Yi thinks that he should pay special attention to it.
Especially when removing and then nailing the nails again, it is inevitable that marks will be left.
He asked Shitao to follow these two points to find it, and he estimated that he could achieve twice the result with half the effort.
Shi Tao nodded repeatedly and said that you and Old Wu were the only ones who could be trusted. He would go to Xinbei Town with Gu Changhai to look for them one by one.
After seeing Shi Tao off, Zhou Yi immediately thought of another thing.
It’s about Lu Xiaoshuang inhaling methane and carbon monoxide.
He immediately returned to the bureau and wanted to ask Song Yiming for advice, but he did not see Song Yiming in the forensic room, but he saw Xu Nian.
Xu Nian was a little surprised when he saw Zhou Yi: "Why are you back again?"
"Oh, I came back because..." Zhou Yi was stunned, "What do you mean by again?"
"I saw you this morning. Has Lu Xiaoshuang's criminal suspect status been revoked?"
Zhou Yi nodded. So that's how it was. "Well, it was cancelled, so I came to pick her up. After all, her parents aren't here."
"Oh, I see... Then where have you placed her now? It might not be safe for her to go back to school in her condition." Xu Nian bit her lip and asked, "Is it not your house? Otherwise, you can let her go to my house..."
"No, I sent her to a friend's place. She's safe."
Xu Nian nodded and whispered, "That's good. Now you can rest assured."
Zhou Yi noticed something subtle and immediately changed the subject, "Let me ask you a question. How long does it take for a person to die from inhaling formaldehyde and carbon monoxide?"
Xu Nian said that there is no fixed time for this, and it mainly depends on the concentration of harmful gases in the surrounding environment.
The higher the concentration, the faster the death. If the methane content in the air exceeds 70%, a person may die in five minutes in such an environment.
This made Zhou Yi immediately run to the technical department to find Lao Qiu and ask about the test results of the harmful gas content in the mine.
Mr. Qiu’s feedback was that the conditions for testing were not met during the first on-site investigation, but they were recently supplemented.
The test results show that the content of the two harmful gases in the mine is actually not high, and the overall concentration is less than 5%.
Lao Qiu said that the reason was very simple: the coal mines underground in Xinbei Town were dug too cleanly.
The reason why there is methane in the mine is that when the coal mine is formed, the decomposition of organic matter produces a large amount of methane.
But the coal mine has been hollowed out, so only the small amount of methane left from the beginning remains, and no new methane gas will be formed.
Moreover, the density of methane is much lower than that of oxygen, and it will accumulate in the upper space in a confined space.
This was also the reason why Lu Xiaoshuang fell down due to dizziness after standing up and walking a short distance, as stated in her confession.
This is also the reason why it can continue to crawl in the cave and look for an exit after falling down.
Then there's carbon monoxide.
Theoretically, there is no carbon monoxide in the mine itself.
However, because a large amount of methane is produced during mining, and methane is extremely explosive, specialized personnel are needed to mix explosives and detonate and eliminate all the methane through explosions.
This is what Meng Dahai from Long Zhiqiang’s gang did.
The blasting work to remove methane actually produces carbon monoxide.
Therefore, legal coal mining businesses will emit carbon monoxide again.
But this requires cost and time. For those illegal coal bosses who are only interested in profit, it is all about money, it is their lifeblood.
That is why illegal mining and safety accidents occur.
Although the concentration of carbon monoxide in the mine is not high, Lao Qiu said that carbon monoxide is only 3 percent lighter than oxygen and is basically mixed with oxygen. It will not float to the surface like methane.
Therefore, if the victim continues to inhale it, it will cause great harm to the body.
Section Chief Qiu's explanation made Zhou Yi understand why Lu Xiaoshuang, who had been treated before and had clearly woken up, was suddenly in danger and had to be rescued later.
This is because continuous inhalation of carbon monoxide is harmful to the body.
As for how long it would take for someone to die in this situation, Lao Qiu said, "I can't give you an exact time."
He also added something that made Zhou Yi laugh and cry. He said that he would not help you do experiments.
Perhaps he was frightened by Zhou Yi's decision to ask Song Yiming to do an experiment, so he asked the technical department to conduct an experiment with harmful gases.
Finally, Lao Qiu gave a maximum reference time of two hours based on the situation.
If a person is in that environment and is constantly falling or lying down, the maximum survival time will not exceed two hours.
Qiu Zhiyong said categorically: "Even if a god came, he wouldn't survive more than two hours!"
The value of this information is as useful as Song Yiming's meat-cutting and frying experiment.
Because this way we can basically determine the time when the murderer threw Lu Xiaoshuang and the human head into the mine.
The afternoon of May 1st.
In other words, it is the same as Zhou Yi's previous estimate.
While the police were searching trash cans on the street for body parts, the murderer took the opportunity to transport the unconscious Lu Xiaoshuang, the head in the travel bag, and the murder weapon to the mine in Xinbei Town, committing what currently appears to be the final criminal act in the case.
This time should be between 2 and 5 in the afternoon.
At the first case meeting at around 4 o'clock that day, Xie Guoqiang gave clear instructions that suspicious vehicles and pedestrians must be strictly checked.
The timing is just right.
Of course, we cannot be a wise man after the event, because no one would have thought of this at the time.
When body parts are discovered, responding quickly and conducting a targeted large-scale search is the correct way to handle the situation.
He did the same thing in his previous life, so even Zhou Yi didn't think there was anything wrong.
He also chose to go to Daguan Street as soon as possible and use his own method to find the head to confirm the identity of the deceased.
After all, who could have thought that at this time, when the streets were full of police officers, the murderer would openly go to the suburbs to dump the body.
So Zhou Yi called Shi Tao and told him that when he was interviewing witnesses, he must pay special attention to any strange vehicles that appeared in Xinbei Town between 2:00 and 5:00 p.m. on May 1st.
Shi Tao was very excited and kept saying, "Zhou Yi, you are my guiding light."
But after hanging up the phone, Zhou Yi had new questions in his mind.
The murderer had clearly kidnapped Lu Xiaoshuang on the afternoon of April 30th, so why did he wait until May 1st to throw her into the mine?
According to the previous analysis, the murderer did not kill Lu Xiaoshuang simply because he needed her to die in a way that was not murder.
But Zhou Yi couldn't think of any reason why the date needed to be precise to May 1st.
Wouldn't it be enough to kidnap the person on April 30th, transport him directly to Xinbei Town and throw him into the mine?
Anyway, it wouldn't make much difference whether Lu Xiaoshuang died in the mine a day earlier or later.
Zhou Yi wondered what was going on here.
Could it be that time did not allow it on the 30th, and it conflicted with the time of disposing the body?
The task force had previously conducted a comprehensive analysis of the time when the body was dumped.
Xu Liu started to disappear on the night of the 28th. It is extremely unlikely that he was able to dismember and dispose of the body that night.
The possibility of dumping the body during the day on the 29th was also relatively small, because it was a sunny day on the 29th, and dumping the body during the day would easily expose the whereabouts and leave traces to be seen by witnesses.
Similarly, the possibility of the body being dumped during the day on the 30th is also very small.
Especially since the latest clues confirmed that the murderer kidnapped Lu Xiaoshuang on the afternoon of the 30th, time is even more urgent.
Therefore, the most likely time of dumping the body would be the night of the 29th.
In the 1990s, except for some special places, the sanitation bureaus of prefecture-level cities did not have enough manpower to clean the garbage bins on the road and the collection points of residents' domestic garbage every day.
The task force contacted the Environmental Sanitation Bureau for confirmation. Due to the high population density of Hongda School, the students produce too much garbage every day. The school’s logistics department will collect all the garbage on campus to the side door every day and hand it over to the Environmental Sanitation Bureau for disposal.
It is cleaned once a day. After all, the education department has special funds to pay to the sanitation department for garbage disposal.
In addition, the nearby snack street produces a large amount of kitchen waste every day, which also needs to be disposed of in a timely manner.
Street trash cans near Hongda and even in most urban areas are cleaned every other day.
After all, there was no garbage classification back then, and there were many trash cans on the streets.
After investigation and verification by the Environmental Sanitation Bureau, it was confirmed that garbage had just been dumped in a garbage bin on the road near Hongda between 9 and 10 pm on the 29th.
Jiang Biao even took people to the garbage dump and searched for a whole day and night to confirm whether there were any body parts in the garbage that had been dumped earlier.
The result was nothing.
From this point, it can be confirmed that the body was dumped at least within the twenty-two hours from after 10 pm on the 29th to before 8 am on the 30th.
The task force unanimously agreed that it was between midnight and dawn on the 30th.
Because the whereabouts in the second half of the night are more covert, which is more consistent with the murderer's criminal psychology of disposing of the body.
Of course, before interrogating Lu Xiaoshuang, the task force could not rule out the possibility that the murderer had dumped the body in a very short time on the afternoon of the 30th.
After all, no valid witnesses have been found so far.
Yes, it’s not that there are no clues. In fact, the police will get a lot of clues when they conduct investigations and visit the police station.
But the problem is that the clues provided by the masses are very one-sided and based on their own standpoints. Many times after investigation, it is found that the goods do not match the description.
Unless the murderer is caught, the accuracy will be higher if you take the murderer's photo and then find witnesses to identify him.
Otherwise, if someone walks by quickly and throws something into the trash can with premeditation, even witnesses may not notice.
So theoretically, the body was disposed of before Lu Xiaoshuang was kidnapped.
Essentially the two things do not conflict.
There must have been some reason why the murderer did not throw Lu Xiaoshuang into the mine on the 30th.
The most likely possibility is that the murderer did not want to do it that afternoon, but was unable to do so.
Some unexpected event forced the murderer to go to the mine the next day.
It is even possible that the murderer took a desperate risk by going to the mine on the afternoon of May 1st.
After all, the police had already begun a large-scale search for body parts on the night of the 30th.
The murderer only needs to walk on the street and pause among the crowd to know what happened.
Lu Xiaoshuang is a living person, and the murderer cannot let her "die an untimely death". He either has to let her go or take the risk and commit crimes again under the noses of the police.
It is naturally impossible to let him go, so there is only one way left.
In other words, the period after 2 p.m. on the 30th may be critical.
Zhou Yi immediately remembered the school celebration Xiao Bing had mentioned earlier. Could it be that the murderer was also attending this event? Leaving without reason would easily arouse suspicion and invalidate his alibi?
It seems that I have to tell Xiang Jie about this and ask him to arrange someone to check the list of participants in this event.
Although judging from the current situation, I'm afraid this matter can only be discussed after finding the woman named "Lulu".
Zhou Yi then remembered that he had asked Chen Yan to wait for him and had completely forgotten about this.
Just as I was about to go downstairs, I suddenly heard thunderous snoring coming from the office of the Third Brigade in front.
"Who could it be at this time? It can't be Captain Wu, right?" Zhou Yi walked over curiously and pushed open the half-closed door.
Then I saw Jiang Biao leaning back in the chair with his mouth wide open, and thunderous snoring came from his mouth.
Zhou Yi was stunned for a moment. It seemed that Jiang Biao was too tired to fall asleep.
Just as I was about to leave and close the door to let him get some good sleep, the snoring stopped abruptly.
Jiang Biao stood up suddenly and asked, "Who?"
"Brother Biao, it's me. Sorry for disturbing your sleep." Zhou Yi said with a helpless smile. His alertness was too high.
Seeing who was coming, Jiang Biao sat down again, stretched out his two big hands to rub his face and said, "Oh Zhou Yi, weren't you with the task force? Why are you back?"
"I just got some information from the forensic and technical departments. Brother Biao, take a nap. I'll be back soon."
Jiang Biao shook his head and said, "No, I'm not going to sleep. I just came back to look for information. I felt a little tired, so I thought I'd sit for a while, but I didn't expect to fall asleep."
Zhou Yi looked at Jiang Biao, whose face was unshaven, covered in sweat and dust, and whose dark circles were almost as big as a panda's.
His body, which was about 1.9 meters tall and as strong as an iron tower, seemed to be a little shaky.
"Brother Biao, how long have you not rested?" Zhou Yi did not leave. He picked up the cup and wanted to pour a cup of hot water for Jiang Biao, but when he tried, the two thermos bottles in the corner were empty, so he had to give up.
Jiang Biao yawned and said, "I don't know. I haven't calculated it."
From the very beginning, Jiang Biao was responsible for searching for body parts. Although most of the body parts were found later, no bones were found, so the search work could not stop.
In addition to bones, there are two other things that are under his responsibility.
The first thing is to check the rapeseed oil used to fry the bodies. There was at least 15 kilograms of rapeseed oil, which was either available in specific places, such as restaurants and food processing plants; or it was purchased around the 28th to commit the crime. Of course, the murderer would not be stupid enough to buy so much at one time, and must have purchased it in batches.
Second, it is the crime scene. In addition to specific locations such as restaurants and food processing plants, it is necessary to check door to door; at the same time, the masses must be mobilized to obtain more suspicious clues.
After all, dismembering a body may not necessarily cause suspicion, as there has been a case like this in the Donghai community before.
But the sound and smell of frying large amounts of meat in the middle of the night could not be concealed.
But obviously, these two points have not produced any effective results, otherwise the information would have been synchronized.
In addition to these three things, Xiao Bing escaped later, and Jiang Biao had one more task to do, because he was the only one with a large number of peripheral police forces available.
The biggest difference between the Hongda case and the Long Zhiqiang case is that a large number of police forces were mobilized in a short period of time. In the Long Zhiqiang case, the target was clear, the situation was serious, and it posed a great threat to social stability, so almost all police forces were mobilized at the first moment, and there was no need to even consider the normal operation of the Hongcheng Public Security Bureau in a short period of time.
Moreover, Long Zhiqiang is an outsider and his purpose is obviously to escape, which will lead to an open game with the police, turning it into a cat-and-mouse game that races against time.
But major cases are different. The murderer is in the dark, and the case is unlikely to be solved in a short period of time. Therefore, when arranging police forces, the normal daily operation of the public security organs must also be taken into consideration. It is impossible to deploy all police forces at once.
If the public security force is worn down over a long period of time, how can social order be maintained?
After all, in the 1990s, there were still a lot of ruthless people, gangsters and hooligans in society.
This was also why Shi Tao hadn't joined the task force before. Besides his personal unwillingness to get involved in such a difficult case where he wouldn't receive much credit, Zhou Yi suspected another reason was that Director Xie had asked Shi Tao to first crack down on some unstable elements who might take advantage of the situation to cause trouble.
So Shi Tao joining the task force today may not necessarily be because they really need him.
But the task that Director Xie had assigned to him earlier should have been almost completed, so it was time to bring him in to work.
This is reasonable, especially after Wu Yongcheng was put on "sick leave", theoretically Shi Tao should have taken his place immediately.
"Zhou Yi," Jiang Biao suddenly said, "Do you think I'm not suitable for this job?"
Zhou Yi was stunned. Has Brother Biao been made to doubt his life?
"Brother Biao, don't underestimate yourself. In the whole of Hongcheng, no one is more experienced than you in large-scale searches." Zhou Yi comforted him.
"But this is really weird. I've searched Hongcheng thoroughly, snatched bones from the mouths of stray dogs, and looked at them, but I can't find a single one."
Jiang Biao said gloomily, "You said Xu Jiaguang also threw away some bones. Although some were indeed not found in the end, at least most of them were salvaged. But this time, there is nothing left."
"Let me be frank. I'm now the most hated police officer in all of Hongcheng. In order to find Xu Liu's bones, I have offended every department I could."
These words made Zhou Yi laugh and cry.
"Brother Biao, your description is too funny." Zhou Yi wanted to make the atmosphere more relaxed and changed the subject.
Jiang Biao asked back, "Which description?"
"It's just snatching bones from the mouths of wild dogs."
Jiang Biao widened his eyes and said, "I'm not just describing it, I really did it..."
Zhou Yi was stunned for a moment. Oh my god, he was actually forced to snatch a bone from a dog's mouth.
"Brother Biao, I think you shouldn't be so anxious. Regarding the matter of not being able to find the bones, I think there might be something wrong with your fundamental thinking."
When Jiang Biao heard this, he couldn't wait to ask, "Zhou Yi, tell me quickly, what's the problem?"
