Bai Song looked at Yan Yu and felt that she was a bit like himself when he had just graduated.
When encountering a big case, I become curious and unable to walk.
Yan Yu had been an intern for two months and this was her first time seeing a murder. Actually, it wasn’t her first time. Last month, a stabbing occurred at the police station next door, and she went to see it through her classmates.
Every police station in the entire East District has students majoring in investigation. Yan Yu is very popular. After she went there, she found out that the murderer had already been caught.
There are too few murders in daily life. Maybe only one or two out of ten murders are murders, and the others are mostly rape. Although that murder looked very tragic, with people being hacked to death in the street, the case was very simple, so simple that any policeman would know how to handle it.
"If you want to stay here, stay here." Bai Song looked at his watch. "There is too little evidence right now, and the basic autopsy hasn't been done yet. I'm going to rest first. If I can't solve the case tomorrow, I'll come back."
"What if the murderer runs away tonight?" Yan Yu was puzzled. She didn't understand why her senior brother was not excited when seeing such a case. This must be a murder case! Yan Yu heard that Bai Song had handled many cases. It stands to reason that her senior brother would also be unable to walk when seeing a case.
"If he wanted to escape, based on the time of poisoning, he might have already fled abroad," Bai Song said, "Have you heard of the drug Difenidol?"
"Is it sleeping pills?" Yan Yu frowned. Although she liked studying reasoning and handling cases, there was still a big gap in her knowledge.
"It's not a sleeping pill, it's a drug for treating motion sickness, and it can prevent and treat dizziness, nausea, and vomiting caused by various reasons or diseases," Bai Song said. "This thing doesn't work that quickly. At high doses, it will first inhibit the central nervous system, then cause excitement, and then continue to inhibit. The cause of death of the poisoned patient was respiratory failure. The reason why they determined that it was poisoning from this drug was mainly because the medicine bottle was found at the scene, and the symptoms of respiratory failure matched. But don't you find a lot of doubts here?"
"Um, senior brother, please explain it to me clearly," Yan Yu thought for a long time but couldn't find any problem.
"When the forensic doctor described the condition of the deceased just now, did you look at the photos?" Bai Song asked back.
"I have seen it," Yan Yu said, "It is indeed the same as what Senior Brother said."
"Then let me ask you, what are the marks of binding on her body?"
"He was poisoned and tied up," Yan Yu blurted out.
"Is there a rope at the scene?" Bai Song asked.
"Uh... that means they take it away after someone dies."
"This drug takes so long to work, why wait two hours for someone to die?" Bai Song asked, "Were there any signs of a violent struggle at the scene? And there were no fewer than four people at the scene, which means there were three suspects. Is it really that hard to kill a woman with three people? The most important question is, is this method too stupid?"
"Brother..." Yan Yu was a little saddened by Bai Song's words. She had never suffered such grievances. Didn't Bai Song's last sentence mean that she was mentally retarded...
"Now we have to wait for the autopsy results to determine whether the cause of death is diphenidol. The presence of medicine bottles and respiratory failure at the scene does not prove that it is diphenidol. This is the first point. Second, Shao Damu has not been found yet. Even if he is found, he may not be the murderer. We need to find him for interrogation. Third, we don't even know the specific circumstances of the deceased, his work and the circle around him, the places he visited before his death, his movements, the people he came into contact with, and any possible conflicts and motives for murder. The basic work is zero. Can we solve the case just by investigating the scene without surveillance?" Bai Song said, "We are just waiting here. It is impossible for the two of us to check these. None of them can be done by two people. If we really go out to check, we will only overdraw our brains and miss many key clues."
"..." Yan Yu said: "So..."
"So go back to sleep. It's already three in the morning. Aren't you sleepy?" Bai Song yawned at the right time. "We who are almost 30 can't compete with you who are in your early 20s in terms of physical strength. I'm so sleepy anyway."
"But isn't it normal to stay up all night to work on a case?" Yan Yu still didn't want to leave. He knew that what Bai Song said was right, but shouldn't he fight side by side with everyone on a case like this?
"You..." Bai Song thought if this wasn't a junior sister from his school, he would definitely not say more: "Which unit are you from?"
"I'm from the East City Branch!" Yan Yu puffed out his chest.
Bai Song held his forehead with his hand: "Okay, whatever you want."
After saying that, Bai Song turned around and left. If Yan Yu wanted to stay up all night, then let her stay up all night. After all, young people...
What Yan Yu didn't understand was that, although it was true that they were both from the East City Branch and the Jinbao Street Police Station, they were both from Group Four, and this case was from Group Two.
In fact, even if it was Team 2, they would not be responsible for the investigation of the case in the later stage, and the organizer was still the Criminal Police Team. Therefore, before receiving a formal invitation from the Criminal Police Team, handling this case would be laborious, offensive, and possibly embarrassing.
It is true that Bai Song is capable of handling cases, but he cannot do it alone. He relies on an entire team.
He was used to cooperating with Sun Jie and Wang Huadong to obtain perfect autopsy and on-site trace reports. Wang Liang was then responsible for full-process monitoring and derivative video data, and Liu Shuyuan was there to analyze and handle external matters. He was responsible for integrating everything and providing investigative direction.
Especially Wang Liang, he can find a lot of video materials that others cannot find, he can analyze big data that many people cannot analyze, and he is proficient in some technical means.
Now that his team is not here, he has already made Captain Lou a little unhappy. If he is forced to stay here and handle the case, it will only affect the investigation of the Criminal Investigation Detachment of the East City Branch.
If you want to solve a difficult problem, you definitely cannot do it by brute force. This is about solving a problem, not killing people. This is not the time to "work miracles with great force."
It's actually okay for Yan Yu to stay here. She won't be offensive. Besides, with a beautiful girl here, these criminal police probably won't be sleepy anymore, so Bai Song didn't say much.
…
After returning to the dormitory, Bai Song reviewed tonight's case again and chose to rest. It was already half past three.
When he woke up, it was already past seven o'clock. Bai Song's biological clock was delayed.
Still feeling a little sleepy, Bai Song shook his head, got up, washed up, and turned on his cell phone, but there was not a single message.
The case has definitely not made any progress.
Without haste, Bai Song put on his clothes and went to the cafeteria.
"Officer Bai," the police officer on duty at the front desk of Group 2 saw Bai Song, "You got up so early. I saw you didn't come back until after 3 a.m. yesterday."
"Have the political commissar and my junior sister returned?" Bai Song asked back.
"The political commissar is back, but I didn't notice your junior sister. She probably hasn't come back yet. She's... isn't your group taking a break today?" said the police officer on duty.
"Well, let's take a rest." Bai Song looked at the time. It was not yet half past eight. He guessed that the police officer on duty had asked a trainee to take his place at the front desk. He didn't want to talk much. He simply ate a few bites and left the cafeteria.
How to describe this kind of behavior? Bai Song really hates it, but he can't say anything. After all, he is not the director. However, he silently took note of these things and will write a report after his visit to the grassroots.
When he arrived at the front desk, Bai Song saw Liu Lifeng and didn't say much. When Bai Song first started working, he also encountered similar things. Old police officers would think that this was "training new comrades", but Bai Song didn't think so.
Bai Song could easily ask Liu Lifeng not to take over for half an hour, but that doesn't mean it would be good for Liu Lifeng.
…
After leaving the police station, Bai Song walked to the club.
There was no police car at the entrance of the club. After Bai Song went in, he found a police car parked in the backyard. He went upstairs directly and found two or three unfamiliar policemen upstairs.
The scene was still cordoned off, and Bai Song was looking over here in plain clothes. Several policemen thought Bai Song was suspicious and came over to ask what was going on. Bai Song showed his police ID and said, "I'm from this police station."
The young policeman looked at the officer's ID, somewhat puzzled, and handed it to another person. The other person was also stunned, and took the officer's ID out and looked at the back of it.
The front has the police number and work unit written on it, and the back has the police rank and specific work unit. The man took a look and was like, "Second-level Police Inspector?" How old is he to be a Second-level Police Inspector?
After carefully confirming that the officer's ID was not a forgery, the police officer respectfully handed it to Bai Song with both hands: "Leader, is there anything else that brings you here?"
He never mentioned that Bai Song mentioned that he was from the police station.
"I am now training at the grassroots level in the police station, and I can indeed be considered a member of the police station," Bai Song said. "I came to the scene last night, and Captain Lou and Political Commissar Yan were both there. Where are they now?"
"Team Lou is now outside trying to catch that man, but there is no news yet. Political Commissar Yan should have gone back home in the middle of the night, and I don't know where he is exactly, but the person that Political Commissar Yan brought is here."
"Oh, oh, oh." Bai Song was actually asking about either Political Commissar Yan's location or Yan Yu's location: "Where is she?"
"Follow me," the man took Bai Song to the house next to the scene.
There were not many guests in the club to begin with, so they didn't want outsiders to know that a murder had occurred here. Therefore, the entire floor was sealed off, and Bai Song couldn't get in without a police officer's ID.
The room next door was also very large. After opening the door, Bai Song found a pile of hamburgers and colas on the exquisite dining table, as well as an ashtray full of cigarette butts.
There were two criminal policemen sitting and sleeping on the sofa. Bai Song had seen them last night. There was another one lying next to the table. It was Yan Yu.
On the contrary, no one touched the big bed.
“Oh oh oh,” Bai Song looked at the situation and said, “Let them all rest for a while.”
Having said that, Bai Song left the room.
After coming out, Bai Song asked, "Is Captain Lou leading the team personally to capture Shao Damu?"
"Yeah." The policeman was actually still a little wary of Bai Song. When he was talking to Bai Song just now, he didn't mention the name Shao Damu. After hearing what Bai Song said, he was 100% sure that Bai Song must have been here last night: "He hasn't been caught yet, but there are some clues."
"Where is the case being investigated at the moment? In that room just now?" Bai Song was puzzled: "This place is not suitable for holding a meeting."
"In your conference room, Political Commissar Yan said that Kong will be in charge of this matter today, and we will go there for the meeting. This case has a big impact, and the leaders of the Municipal Bureau may inquire about it today."
"Well, it's normal in our institute. It's close to here," Bai Song nodded.
It’s okay for the Municipal Bureau to intervene, this is normal.
There are no more than ten homicides in Shangjing City in a month, and no more than two murders. If the case is not solved within eight hours, the Municipal Bureau will definitely send someone.
"Then I won't stay here. There's no point in me going in," Bai Song said, "I'll go back to the police station first."
"Okay, leader, please slow down." The man waved his hand to Bai Song to show his politeness.
After Bai Song left, the two policemen immediately used their mobile phones to search for Bai Song on Baidu, and they actually found him. One of them said, "Oh my god, it's this great guy. Why does his name sound so familiar..."
…
After returning to the police station, Bai Song went to find Chief Kong.
As an old man in the system, Bai Song understands that it is important to have a legitimate reason for everything. He tells Kong about this matter, and then Kong can arrange for Bai Song to join the special task force of the police station, so that he will not be shackled by the identity of Group 4.
Although the main investigative unit is the Criminal Police Team, and even homicide cases are 100% under the jurisdiction of the Criminal Police Team, there is a lot of surrounding evidence that needs to be investigated in this case, so we must rely on the police station.
Many cases were solved by police officers from a certain police station providing a clue because they might have an informant.
When Chief Kong heard Bai Song's idea, he immediately expressed his approval: "The leaders of the Municipal Bureau will be coming over soon. They may send forensic doctors and on-site investigators. In addition, Mr. Wang from the Municipal Bureau's Criminal Division will also be here. You should also attend the meeting."
"Okay," Bai Song said, "Master Kong, this is it. I may act independently or call for external assistance. This may have a certain impact on you."
"It's okay," Kong said. "It's not that bureaucratic. Although the criminal police team is responsible for homicide cases, if there is a homicide case that remains unsolved in our jurisdiction this year, it will not only be a shame, but also have a great impact on our police station. So, if you can provide some external help, even from the department, that's fine. I can help. I have no problem with any procedures that can be handled."
"Okay, thank you, Chief Kong," Bai Song said, "I said before that suicide is not ruled out in this case. But I see that the Lou detachment has not found Shao Damu yet, which means there is a great possibility that he has escaped. In this case, suicide can basically be ruled out, so this is a well-planned murder. This requires our joint efforts."
At this moment, Kong received a call. It should be the leaders from the city and district, who will be here soon.
