Chapter 12
On the other side, Jiang Aichen came out of the interrogation room with a tired look on his face. He subconsciously pinched his nose bridge with his right hand a few times.
Tang Jianyue, who was recording in the interrogation room with him, asked with concern: "Captain Jiang, are you okay?"
"It's okay." Jiang Aichen answered calmly.
Tang Jianyue naturally knew why Jiang Aichen was so tired.
Although the imperial capital is not far from Beihai, it takes three hours to drive there.
The round trip takes at least six hours.
Jiang Aichen was delayed by an emergency case yesterday and left late to begin with.
The fact that he could appear here at this time must have meant that he had rushed back overnight.
You can imagine how hard that night was.
Tang Jianyue said with a little distress: "Captain Jiang, do you... want to take a rest?"
"No need," Jiang Aichen replied, "The murderer may commit another crime in 48 hours. No one in our police force can rest today."
"48 hours?" Tang Jianyue was a little shocked. "Captain Jiang, how did you know the murderer's exact time of committing the crime? We obviously didn't find any pattern in the three cases."
"Could it be that you know who the murderer is?"
Jiang Aichen did not hide anything, but said bluntly: "No, Lin Anyu told me 48 hours."
"Lin Anyu?" Tang Jianyue felt something was wrong. "But Captain Jiang, Sister Lin, didn't she lose her memory? In the past few years in our Beihai Criminal Police Team, she ranked last in all tests. Even when you sent her to the police team to help, the most she could do was pour water and buy lunch. Many colleagues in the police team reported that she even had difficulty finding missing cats and dogs."
Jiang Aichen pondered for a while.
He knew she had lost her memory.
He also knew that in the past three years, there was no trace of that man around her.
He also knew that she was not the one he was looking for.
But, despite this...
"That face is still so trustworthy."
The more Tang Jian listened to Jiang Aichen's mutterings, the less real they sounded.
He asked, "Captain Jiang, what did you say?"
"Nothing," Jiang Aichen said casually, "Xi Zixuan concealed something, and he and Yu Anan stayed in the bureau for observation. The others will have a meeting in the conference room."
-
About half an hour later, the conference room on the third floor was full of people.
Taking advantage of the time when Jiang Aichen had not arrived yet, the criminal police who arrived earlier took the lead in sharing the clues they had found.
Lin Anyu sat in the corner, holding a photo of two figures captured from the mall’s surveillance video.
One of them had no disguise on his face, and Lin Anyu was 90% sure that he was Xi Zixuan.
As for the other one...
No matter how hard Lin Anyu tried to identify him, she felt that judging from his body proportions, he should be a man.
Could it be that the person wrapped in this package, like the figure cosplaying as Xiao Hei in Conan, is also Xi Zixuan?
But if it was really him, why did he appear twice?
Could it be that he noticed something was missing from the surveillance video, which is why he appeared the second time?
But this shouldn’t be the case. If Xi Zixuan appeared in the monitoring room for the second time to check for omissions, then why wasn’t the video of him entering and leaving the monitoring room replaced?
What did he replace when he checked for omissions a second time?
If this figure is not Xi Zixuan, then who is he?
What is the connection with Tang Shuang’s case?
Or did he just need to replace the surveillance video secretly for some special reason?
Various questions lingered in Lin Anyu's mind.
Even when she was thinking, there was a period of time when she felt that her brain seemed to become a little "heavy" and her thoughts began to become dull, as if they were covered with a layer of paste.
At this time, Jiang Aichen pushed the door and walked in. The moment he walked towards the whiteboard, his eyes fell on Lin Anyu.
Then quickly retract it.
He sat at the front of the conference room and adjusted his swivel chair in front of the whiteboard.
After going through the thoughts in his mind, he asked, "What did you find?"
As the deputy captain, Jiang Nan took the lead and said, "Today, Jian Yue and I investigated the deceased's call records before her death. We found that in recent times, in addition to frequent phone calls with colleagues, the deceased only had a phone call with her boyfriend Xi Zixuan on the 22nd. There were no other call records in the past week."
Jiang Aichen: "How is the investigation of the deceased's cell phone going?"
A policeman in the corner said: "Technicians are working hard to crack the password of the phone, and it will take time."
Jiang Nan continued, "When we went to question the deceased's colleagues, we used their WeChat to log into their Moments. We found that the only things the deceased had posted on his Moments were food and fitness videos. We didn't see any signs of suicide."
"But, strangely, on April 16, the deceased posted this circle of friends," Jiang Nan stood up and pulled up a screenshot of the circle of friends on a screen. He said, "On April 16, the deceased said that she always felt that someone was watching her recently, and she felt creepy at home. She also asked if there were any girls in the circle of friends who felt the same way as her."
Jiang Aichen pondered for a while: "What did the deceased's colleagues say?"
Jiang Nan said: "They said that the deceased was indeed suspicious for a while before his death, and later called the police. After the police checked all the surveillance cameras and found nothing, they hastily closed the case. After the case was closed, the deceased's suspiciousness was gone, and he went to work every day in high spirits."
"Let's put the tracking aside for now. We'll go to the local police station to find out more about the situation." Jiang Aichen asked, then turned his head to Meng Qirang, "What did you find during the autopsy?"
Meng Qirang said: "After testing the stomach and blood of the deceased, in addition to the sleeping pills we found last time, we also found a small amount of alcohol and honey residues in the stomach of the deceased. We even detected a trace amount of lysine diethylamide in the blood."
The entire conference room fell silent.
Jiang Aichen didn't dwell on Meng Qirang's words. He continued to ask, "Have other people in the community asked this?"
As the deputy captain of the team, Jiang Nan summarized the investigation information of everyone before the meeting. He answered: "According to other residents in the community, the deceased Tang Shuang was a girl who lived a very regular life. Since she moved to this community, she always insisted on getting up around 5 o'clock to run in the morning, and then going to work around 8 o'clock."
"She rarely stayed outside after get off work at night. The reporter said that when she returned home after picking up her grandson, she could usually see the lights on in the deceased's house. But every Wednesday, when she passed by the deceased's door, the lights were off."
Jiang Nan glanced at his notes and continued, "According to Tang Shuang's colleagues' recollections, on the 22nd, Tang Shuang left the company half an hour early. And the 22nd was a Wednesday."
Tang Jianyue added: "Just now, Captain Jiang and I asked Xi Zixuan. He admitted that every Wednesday is his date with Tang Shuang. On the 22nd, they went to Shengxia Park for a date and ate at a food stall nearby. But for some reason, Tang Shuang was not in a good mood that day and drank a few glasses of white wine on an empty stomach."
Tang Jianyue was responsible for interrogating Xi Zixuan, while Li Tang was responsible for interrogating Yu Anan.
Li Tang said seriously: "Yu Anan admitted that she had been in a relationship with Xi Zixuan for two years, but she has always insisted that she did not know that Xi Zixuan and Tang Shuang were lovers."
"She also said that when Captain Jiang and Lin Anyu asked her about it, she couldn't remember clearly, and she just assumed that she and Xi Zixuan were in the gym on the night of the 22nd."
Jiang Aichen pondered for a while and asked, "Ask the people who are monitoring the food stalls around Shengxia Park to check the time when Tang Shuang and Xi Zixuan left."
In the corner, someone shouted, "22nd, 9:28 pm."
After getting the answer, Jiang Aichen organized his words: "Now we have three questions to solve. First, according to the reporter, the last time she saw the deceased was around 9:30, and the deceased was cleaning at home. But according to the surveillance we retrieved, the deceased was still at the food stall near Shengxia Park at 9:28. Shengxia Park is not close to where the deceased lives, and it takes at least 20 minutes to drive. This means that at 9:30, the person cleaning the deceased's house was not the deceased."
"Secondly, according to Xi Zixuan, after he and Tang Shuang finished drinking that night, he personally drove Tang Shuang home. Since he had appeared at the crime scene, why were there no footprints or fingerprints at the scene?"
"Third, the reporter found the deceased when he was returning home from shopping at 10 o'clock. According to the length of time the reporter spent shopping, the distance to the vegetable market, and the average length of time the reporter usually spends shopping, it can be inferred that the reporter left the house at around 7 o'clock and found the body at 10 o'clock. However, according to our investigation, there were no signs of dragging or moving on the body, so it was initially determined to be the first crime scene. The windows at the crime scene are interconnected and there are no blind spots at the crime scene. Basically, anyone passing by can clearly see into the house."
"The deceased died at 5 a.m., so it was impossible for the reporter to not find the body hanging inside when he went out at around 7 a.m. So it is very likely that the curtains next to the window were drawn at the time, and the reporter's view was blocked when he passed by for the first time. The curtains were drawn the second time, and the reporter discovered the body hanging from the roof beam."
"To sum up, I have sufficient reason to suspect that there must be more than one person at the crime scene that night. As for whether the person who appeared at Tang Shuang's home around 9 o'clock and the person who appeared at the crime scene between 7 and 10 in the morning are the same person, it remains to be discussed."
Jiang Aichen put his hands down and said, "Finally, I think there are many contradictions in Xi Zixuan's testimony. When you are investigating, pay more attention to the details."
"Yes." Everyone responded in unison.
Only Lin Anyu seemed to be out of the situation.
Jiang Aichen, who had been paying attention to her, suddenly called out, "Lin Anyu."
Hearing her own name, Lin Anyu came back to her senses instantly. She stood up from her chair reflexively: "Here!"
Puff——
There was laughter all around.
The serious atmosphere in the conference room immediately eased.
Jiang Aichen's face was calm. She patiently asked, "What did you find?"
Lin Anyu did not hide it. She said, "In fact, everyone's behavior has a certain purpose. For example, we are here to study and discuss the case in order to solve it; workers work to make money. Everything exists for a purpose. So what is the purpose of Tang Shuang's alcohol, sleeping pills, and hallucinogens?"
"Fatal? But if it's just fatal, it can be solved with just a rope."
