Ren Qiang and Zhang Hui's expressions froze slightly.
The detachment already has a relatively clear grasp of Liang Song's situation.
Forty-eight years old, with a wife and two children.
The eldest child was born to him and his ex-wife and is already in high school.
The younger one was born to my current wife and has just entered kindergarten.
Liang Song remarried three years ago. His wife is an art teacher at Haizhou No. 1 Middle School. She also met her when she was studying painting with Liang Song.
As a result, just two years after their wedding, Liang Song fell in love with someone else, and he was also his student.
"Who is Zhang Zixuan's boyfriend?"
"My name is Li Hongtao. I'm a teacher at their school. He came to see me two months ago."
"Looking for you?"
"Did you have a conflict?"
"No, he warned me not to get involved with Zixuan again, and I haven't seen him since."
Li Hongtao...
Zhang Hui recorded the relevant information, and Ren Qiang then asked: "Tell me when did you last see Zhang Zixuan and where was it?"
after an hour.
Conference room one.
Ren Qiang began to report on the interrogation.
"Liang Song and Zhang Zixuan have had an inappropriate sexual relationship for a long time."
"On August 12, Zhang Zixuan's boyfriend Li Hongtao came to Liang Song and issued a warning to Liang Song."
"But there was no conflict between the two."
"The last time Liang Song saw Zhang Zixuan was on September 21, which was the first day of Zhang Zixuan's family leave."
"That day happened to be Wednesday. The two met in the studio. After having sex, Zhang Zixuan left."
"According to what Liang Song said, Zhang Zixuan is going back to Tianzhou City, and the two of them agreed to travel together in a week, during the National Day holiday."
"That's about it."
Ren Qiang returned to his seat and Qin Yong continued to preside over the meeting.
"Everyone, tell me what you think."
Wang Shuai from the action group was the first to speak: "I think this Liang Song is dishonest and did not tell the truth."
"There are several points. First, Liang Song's fingerprints appeared on Zhang Zixuan's skin after his death. What does this mean?"
"This means that he came into contact with Zhang Zixuan's skin. If he didn't kill the person, who else could have killed him?"
"Second, since the two of them had agreed to travel during National Day, but Zhang Zixuan never showed up, why didn't he call the police?"
"Third, Zhang Zixuan's parents said that they had no idea about Zhang Zixuan's request for family leave."
"And Liang Song also said that Zhang Zixuan would return to Tianzhou City after meeting him on September 21."
"Since he is going home, wouldn't Zhang Zixuan tell his parents in advance?"
"Now all the clues point to Liang Song's murder. I think we still need to re-examine him."
Wang Shuai's speech resonated with many criminal police officers.
Not to mention other things, Liang Song is indeed the biggest suspect, just his fingerprints.
"Do you have any other opinions?"
Qin Yong looked around, Zhang Hui shook his head: "Captain Qin, I participated in the entire interrogation process of Liang Song."
"I think there is a suspicion that Liang Song is the murderer, but it's not big."
"Oh? Tell me why he is not a big suspect."
Zhang Hui stood up and walked to the whiteboard: "First of all, I don't think Liang Song had any motive to kill Zhang Zixuan."
On the whiteboard, Zhang Hui wrote the names of the two people: "Liang Song and Zhang Zixuan have always maintained an improper relationship between men and women."
"In this relationship, Liang Song cheated on her husband, and Zhang Zixuan cheated on her boyfriend."
"From this perspective, both Liang Song's wife and Zhang Zixuan's boyfriend had the motive to kill Zhang Zixuan."
"But only Liang Song, he had no reason to kill Zhang Zixuan."
"Also, when Liang Song heard the news of Zhang Zixuan's death just now, he was very shocked. His expression didn't seem to be fake."
"As for what Wang Shuai said, the first piece of evidence is that the fingerprints on Zhang Zixuan's skin were probably left when the two were intimate."
"If, I mean if, Zhang Zixuan was killed on the same day after the two were intimate, then it is more likely that Liang Song's fingerprints were left behind."
"In addition, Lu Chuan only matched two fingerprints on the skin, but there was another fingerprint that did not match the owner."
Seventy-nine fingerprints, seventy-eight of them found their owner, except for one, the target was not found in the database.
"Secondly, regarding the National Day tourism, I think this finding can be explained."
Zhang Hui took out a mobile phone: "This is Liang Song's mobile phone. We found this in the chat history."
"My dear, my father is sick and needs to stay in Tianzhou for a few more days. I can't go out with you on the 11th..."
"On September 28, Zhang Zixuan sent this message to Liang Song."
"Not only that, we found in the Moments that just the day before yesterday, the day before we discovered the human skin painting, Zhang Zixuan's Moments were still being updated!"
The day before yesterday?
Although the specific time of Zhang Zixuan's death is not precise, it can only be included within a month.
However, it is absolutely impossible that I was still posting on Moments the day before yesterday.
Because that painting had been delivered to the studio last Thursday.
"You mean that the murderer actually had Zhang Zixuan's cell phone the whole time?"
"This is for sure, and I suspect that the message Zhang Zixuan sent to Liang Song was also sent by the murderer."
"Because Liang Song sent video invitations to Zhang Zixuan on September 28 and October 2, but they were both rejected."
Key progress has been made in the investigation of the case.
Although Liang Song's fingerprints appeared on Zhang Zixuan's skin, as Zhang Hui said, they might have been left when the two were intimate.
Although the skin was soaked in formalin later, the fingerprints may have been protected, so it was extracted by Lu Chuan.
The other fingerprint, which has not been matched to everyone, is most likely to be left by the murderer.
"Increase the scope of the investigation, investigate all the people Liang Song and Zhang Zixuan know, and compare and analyze them with the fingerprints on the human skin."
"In addition, the investigation will focus on Zhang Zixuan's boyfriend Li Hongtao and Liang Song's wife Chen Yating."
The determination of the identity of the human skin and the results of fingerprint comparison made the next investigation direction of the action team very clear.
The time and space trajectory of Zhang Zixuan is becoming increasingly clear.
While Ren Qiang, Sun Jun and others expanded the search scope, Lu Chuan fell asleep with his head covered.
After working continuously for more than forty hours, Lu Chuan was already exhausted.
On the sofa in the office, it was already 9:30 pm when Lu Chuan woke up.
After completing the fingerprint identification analysis in the morning, Lu Chuan was so tired that he fell asleep in the office instead of going home.
Lu Chuan opened his eyes and stretched in a daze.
"woke up?"
It was Liu Guodong's familiar voice: "The porridge left for you in the cafeteria this afternoon has been put in a thermos bucket. You drink some first, and we will go out to eat later."
"Master? Why are you still here?"
Lu Chuan looked at the time, it was already after nine o'clock in the evening.
"You haven't gone back yet, can I leave?"
"I asked Lao Bai and Yang Sen to go back first in the afternoon."
Lu Chuan nodded and picked up the porridge bowl handed over by Liu Guodong: "I haven't eaten for a day, so I'm really hungry."
"Master, how is the case? Is there any progress?"
Liu Guodong nodded: "The suspect has been caught."
Um?
"Caught?"
Lu Chuan didn't expect that the case would be solved after he slept for a few hours: "Is it that grassroots painter?"
Two of the three fingerprints on the human skin matched Liang Song.
Normally speaking, Liang Song is most likely to be the murderer.
Moreover, the painting was found in his studio.
But Liu Guodong shook his head: "It's not Liang Song, it's someone else."
"who?"
"The owner of the third fingerprint."
