Jiang Yuan completed the investigation and returned to the Changyang City Criminal Police Detachment. He first asked Meng Chengbiao this question.
Meng Chengbiao shook his head: "It didn't go very well. Li Haojie is still a minor, and there are quite a lot of restrictions during the interrogation. It will probably take another day, at least."
"Don't worry." Jiang Yuan's mood was quite stable.
Jiang Yuan's dedicated case backlog class is equivalent to handling cases in a different place. Due to Jiang Yuan's fame, countless pairs of eyes are staring at it, wishing that every step was looked at under a magnifying glass. Various procedural requirements have inevitably been lowered.
Jiang Yuan had already expected the efficiency of the interrogation.
Meng Chengbiao breathed a sigh of relief and said, "I'll go back and think of a way to break through. The prosecutor from the procuratorate here is following me the whole time, and I have to write something to him."
Jiang Yuan comforted Meng Chengbiao for a few more words, then went to the Changyang Criminal Science Center to read the reports produced by the laboratory here.
Many people read reports only for the conclusions in the report, but the information gained in this way is obviously the least. The conclusions in the report can be revised, and many times it is necessary to study them in conjunction with the specific information in the report. Furthermore, the conclusions in the report
Specific information can provide more guidance.
Wan Baoming, the director of the Criminal Science and Technology Center, walked around with Jiang Yuan and picked up a trolley of information, all of which were various inspection materials brought back in the past two days, including a lot of trace evidence.
Several people sat in the office and studied together for a long time. Finally, Jiang Yuan put down the report in his hand and said, "It's basically useless."
"That's right." Wan Baoming sighed.
"Don't worry." Jiang Yuan is now very experienced in handling cases. He does not need any skills and is also a qualified task force leader.
Although this case is still serious, Jiang Yuan is still very confident.
Jiang Yuandao: "The Criminal Division will continue to collect evidence to see if they can identify Li Haojie. Li Haojie is a minor. The family may be lucky. If there is some strong evidence that can be used to prove it, the Li family will probably give up.
of."
Wan Baoming nodded solemnly: "Li Haojie is already over 16 years old. He can be tried and sentenced as an adult. Even if he is not sentenced to death, he can still be put in jail."
Jiang Yuan nodded.
While he was talking, Jiang Yuan's phone rang.
Jiang Yuan answered the phone and Meng Chengbiao's voice was dull.
Jiang Yuan frowned, and the spirit of forensic medicine suddenly came over him: "You tried people to death?"
"That's not the case. That's not the case." Meng Chengbiao felt a little relieved inexplicably. If in Jiang Yuan's mind, interrogating people to death was a bit of a surprise, then what he was going to say now was really no big deal.
.
Jiang Yuan: "What accident?"
Meng Chengbiao coughed twice, then his tone became more serious, and said: "Li Haojie confessed that he did have a puppy love with the victim Sun Xiuwen, and climbed up the window of Li's house many times, and occasionally called Sun Xiuwen to come out to play. But
...On the day of the incident, Li Haojie had alibi and claimed that he did not ask Sun Xiuwen out."
"What evidence?"
"He took several videos at home, and also had video calls with relatives out of town. Preliminary verification shows that it should be true."
"In other words, Li Haojie has been ruled out as a suspect again?" Jiang Yuan spoke to the microphone, his voice rising a little, feeling a little unhappy.
"Yes." Meng Chengbiao replied helplessly.
"Where is Li Haojie's brother? He should be an adult. Have you interrogated him?" Jiang Yuan was still a little unhappy.
"He is an adult, and the interrogation went smoothly, but he was also at home that day and participated in the video call of that relative. In addition, Li Haojie's brother has a mobile phone, and we have searched it, but there is no evidence."
Having said that, the suspicion of Li Haojie's family has basically been eliminated.
Jiang Yuan frowned slightly.
Meng Chengbiao waited for a few seconds, and when there was no response on the phone, he couldn't help but said casually: "Captain Jiang, in this case, are we going to consider impromptu passion killing?"
"Unlikely." Jiang Yuan said resolutely: "Previously, the criminal police detachment considered random killings based on the time of death from 6 to 8 in the morning. This time period is when the deceased goes to school, and there is a possibility that people and cars passing by will look at him.
to, and then commit infringement.”
Jiang Yuan spoke to the phone and said: "Now, the time of death is determined to be 3 o'clock in the morning. At this time, the victim Sun Xiuwen cannot enter or leave through the front door. Her mother and stepfather live on the first floor, and no movement at the door can be heard.
Yu Er. Moreover, Sun Xiuwen already has a mature strategy for circumventing the wall, so there is no need to take risks from the front entrance."
Meng Chengbiao understood a little at this time and couldn't help but said: "The jeans that Sun Xiuwen used to climb over the wall were bunched up and placed in the closet. If Sun Xiuwen climbed downstairs alone, who would help her collect the bunch of jeans?"
Jiang Yuan: "That's right."
Meng Chengbiao was completely involved and couldn't help but said: "Isn't this a paradox? Sun Xiuwen didn't take the initiative to climb the stairs, but died in her own home at 3 o'clock in the morning. So if the murderer took the initiative to get into her home, her home was not
The first scene, and after the murderer escaped, who put away the ball of jeans?"
Jiang Yuan thought and did not answer immediately.
Meng Chengbiao's interest increased, and Detective Instinct returned for a limited time, asking: "Could it be Sun Xiuwen's mother who secretly put away the jeans because she was worried about publicity and other issues..."
At this time, Jiang Yuan recalled the bridge deck at the scene, interrupted Meng Chengbiao, and said: "The footprints on the wall are still relatively fresh."
"What's the meaning?"
"Although it is impossible to accurately determine the specific time when the footprints were left, it can be seen that Sun Xiuwen climbed the wall with a relatively high frequency."
Meng Chengbiao put away his thoughts of Holmes and immediately turned to Watson, asking: "What does this mean?"
"Do young people today climb up walls just to have a tryst with their boyfriends? It's too monotonous." Jiang Yuandao said: "You can interrogate Li Haojie again and ask, who else does Sun Xiuwen meet when she climbs up walls?
People knew that she would climb out of the wall, or rather, if she climbed out of the wall, besides meeting Li Haojie, who else would she meet?"
"Yes." Meng Chengbiao understood and took action immediately.
Half an hour later.
Meng Chengbiao called again and said, "Captain Jiang, you know things like a god."
"Is there anyone else?" Jiang Yuan was also waiting for Meng Chengbiao's call.
Meng Chengbiao said "En" and said: "Sun Xiuwen also has two best friends. Occasionally, Sun Xiuwen will crawl out to play with her best friends."
It is not easy for a best friend to strangle another best friend to death, and it is even more difficult to use a pillow.
Jiang Yuan thought and asked: "What are you playing for?"
"We watch movies, drink, and dance together. They have a secret base. It's the home of a relative of one of my best friends' boyfriends. They don't usually come back, but they have all the water, electricity, and electrical appliances."
Jiang Yuan immediately breathed a sigh of relief: "In other words, there is another man who knows that Sun Xiuwen will often climb out of the wall."
"Two." Meng Chengbiao said: "Both best friends have boyfriends."
"Bring them all back." Jiang Yuan paused and said, "I will also go to the scene again."
