Ren Qiang and Zhang Hui's expressions froze slightly.

Liang Song's situation is relatively clear to the detachment.

Forty-eight years old, with a wife and children, and two children.

The eldest child was born to him and his ex-wife, and he is already in high school.

The younger one was born to his current wife and has just started kindergarten.

And Liang Song remarried three years ago, his wife is an art teacher at Haizhou No. 1 Middle School, and she also met when she was learning to paint with Liang Song.

As a result, just two years after getting married, Liang Song fell in love with someone else again, and he was also his student.

"Who is Zhang Zixuan's boyfriend?"

"His name is Li Hongtao, he is a teacher at their school, and he came to me two months ago."

"Got you?"

"You're in conflict?"

"No, he warned me not to entangle with Zixuan anymore, and I haven't seen him since."

Li Hongtao......

Zhang Hui recorded the relevant information, and Ren Qiang then asked: "Tell me when was the last time you saw Zhang Zixuan, and where was you?" ”

An hour later.

Conference Room 1.

Ren Qiang began to report on the interrogation.

"Liang Song and Zhang Zixuan have maintained an improper sexual relationship for a long time."

"On August 12, Zhang Zixuan's boyfriend Li Hongtao once looked for Liang Song and issued a warning to Liang Song."

"But the two didn't clash."

"The last time Liang Song saw Zhang Zixuan was on September 21, that is, the first day of Zhang Zixuan's family leave."

"It happened to be Wednesday, the two met in the studio, and after having a relationship, Zhang Zixuan left."

"According to Liang Song, Zhang Zixuan wants to go back to Tianzhou City, and the two agreed to travel together a week later, that is, during the eleventh day."

"That's the general situation."

Ren Qiang returned to his seat, and Qin Yong continued to preside over the meeting.

"Let's talk about it, what do you think?"

Wang Shuai of the action group was the first to speak: "I think this Liang Song is not honest and does not tell the truth. ”

"There are a few points, first, Liang Song's fingerprints appeared on Zhang Zixuan's skin after his death, what does this mean?"

"This shows that he has touched Zhang Zixuan's skin, he didn't kill the person, who else killed it?"

"Second, since the two have agreed to travel during the eleventh day, but Zhang Zixuan has not appeared, why didn't he call the police?"

"Third, Zhang Zixuan's parents said that they didn't know about Zhang Zixuan's family leave."

"And Liang Song said that Zhang Zixuan would return to Tianzhou City after meeting him on September 21."

"Since you want to go home, won't Zhang Zixuan tell her parents in advance?"

"Now all the clues point to Liang Song's murder, I think it still has to be retried."

Wang Shuai's speech resonated with many criminal policemen.

Not to mention anything else, it is fingerprints, and Liang Song is indeed the most suspicious.

"Do you have any other opinions?"

Qin Yong looked around, and Zhang Hui shook his head: "Team Qin, I participated in all of Liang Song's interrogations. ”

"I think Liang Song is suspected of being a murderer, but it's not big."

"Oh? Tell me why he's not so suspicious. ”

Zhang Hui stood up and walked to the whiteboard: "First of all, I don't think Liang Song has a motive to kill Zhang Zixuan. ”

On the whiteboard, Zhang Hui wrote the names of the two: "Liang Song and Zhang Zixuan have always maintained an improper relationship between men and women. ”

"In this relationship, Liang Song cheated in marriage, and Zhang Zixuan betrayed her boyfriend."

"From this point of view, whether it is Liang Song's wife or Zhang Zixuan's boyfriend, they all have motives to kill Zhang Zixuan."

"But only Liang Song, he has no reason to kill Zhang Zixuan."

"Also, when Liang Song heard the news of Zhang Zixuan's death just now, he was very shocked, and that expression didn't seem to be fake."

"As for what Wang Shuai said, the first piece of evidence, the fingerprints on Zhang Zixuan's human skin, are likely to be left by the two when they were making love."

"If, I mean, if Zhang Zixuan was killed on the same day after the two made out, then it is more likely that Liang Song's fingerprints were left."

"In addition, Lu Chuan only matched the fingerprints on the two skins, but there was one fingerprint that did not match the owner."

Of the seventy-nine fingerprints, seventy-eight found their owners, only one, and no targets were found in the database.

"Second, regarding Eleven 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 log." ”

"My dear, my father is sick and needs to stay in Tianzhou for a few more days, and Eleven can't go out with you......"

"On September 28, Zhang Zixuan sent this message to Liang Song."

"Not only that, we found out in the circle of friends that just the day before yesterday, that is, the day before we found the human skin painting, Zhang Zixuan's circle of friends was still being updated!"

Day before yesterday?

Although the specific time of Zhang Zixuan's death is only precise, it can only be included within one month.

However, the day before yesterday, it was absolutely impossible to still post on Moments.

Because, the painting had been delivered to the studio last Thursday.

"You mean that the murderer has actually been holding Zhang Zixuan's mobile phone?"

"This is for sure, and I suspect that the message sent by Zhang Zixuan to Liang Song was also sent by the murderer."

"Because Liang Song sent video invitations to Zhang Zixuan on September 28 and October 2 respectively, but they were all refused."

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, it may have been left when the two were intimate.

Although the skin was soaked in formalin in the later stage, the fingerprints may have been protected on the contrary, so they were extracted by Lu Chuan.

And the other one, which did not match everyone's fingerprints, is most likely left by the murderer.

"Increase the scope of investigation, check all the people Liang Song and Zhang Zixuan knew, and compare and analyze them with the fingerprints on human skin."

"In addition, the focus is on the investigation of 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 the fingerprint comparison made the next investigation direction of the action team very clear.

The trajectory of Zhang Zixuan's time and space is also becoming clearer and clearer.

When Ren Qiang, Sun Jun and others expanded the scope of the search, Lu Chuan slept with his head covered.

After working for more than forty hours in a row, Lu Chuan was already exhausted.

On the sofa in the office, Lu Chuan woke up at half past nine in the evening.

After doing the fingerprint identification and analysis in the morning, Lu Chuan was so tired that he didn't go home, and fell asleep directly in the office.

Lu Chuan, who opened his eyes, stretched out in a daze.

"Awake?"

It was Liu Guodong's familiar voice: "The porridge left for you in the canteen in the afternoon is put in a thermos bucket, you drink some first, and then we will go out to eat." ”

"Master? Why are you still here? ”

Lu Chuan looked at the time, it was already more than nine o'clock in the evening.

"You haven't even gone back, can I go?"

"In the afternoon, I asked Lao Bai and Yang Sen to go back first."

Lu Chuan nodded, and picked up the porridge bowl handed over by Liu Guodong: "I haven't eaten for a day, I'm really a little hungry." ”

"Master, how is the case, is there any progress?"

Liu Guodong nodded: "The suspect has been caught." ”

Well?

"Caught?"

Lu Chuan didn't expect that after sleeping for a few hours, the case was solved: "Is it the grassroots painter?" ”

Of the three fingerprints on the human skin, two of them hit Liang Song.

Normally, Liang Song is the most likely murderer.

Moreover, the painting was found in his studio.

As a result, Liu Guodong shook his head: "It's not Liang Song, it's someone else." ”

"Who?"

"The owner of the third fingerprint."
