With the detective's description, a vague picture has gradually become clear.

The informant is Zhang Qin's husband Hong Wei. About a week ago, he reluctantly came to the office to report his disappearance, without the slightest impatience of ordinary police officers, but with an indifferent indifference that impressed people.

According to his account at the time, his wife had been at home the night before, disappeared the next morning, and did not return home the following night. The wife used to have a mistress, and he strongly suspected that she went to the mistress, but because the relationship between the two had long been broken, he didn't take it very seriously, until the next day, when he went to catch the adulterer, the other party said that the wife had not appeared.

From Hong Wei's report to Zhang Qin's mother coming to the institute again for help, during this period, Zhang Qin's daughter once posted a missing person notice on the Internet, and almost all over her mother's circle of friends, but found nothing.

According to her daughter, her parents have always been in discord and often quarrel, but her mother is kind and popular, and has never had any disputes with other people. The mother's personality is optimistic, usually very aggressive, her heart has never been hidden, there have been no emergencies at home recently, and it is impossible to have suicidal tendencies. And recently my daughter is about to take the high school entrance examination, and her mother has been very concerned about her homework, helping to collect school information, in addition to increasing the density of tutoring by tutors, she also personally accompanies her tutoring homework every day, and it is impossible to run away from home for anything at this juncture.

Now, the task force is facing several suspicious points. First, Hong Wei did not report the case immediately after Zhang Qin's disappearance, but a week later, under the repeated urging of his mother-in-law, he reluctantly called the police. Second, after Zhang Qin's disappearance, in the days before Hong Wei reported the case, he suddenly dismissed his daughter's home tutor, who had been tutoring his daughter for more than two years. Third, Hong Wei claimed that after discovering his wife's disappearance, he searched for her friends everywhere, but what we know is that he did not go to work for a week, and there is no reliable witness to confirm all his whereabouts.

"Zhang Qin's mobile phone has not been recharged in the past few days, and there is no movement in the bank account, according to the comprehensive inference of the information we have, Zhang Qin is very likely to be killed for many days." The investigator finally reported.

Qiao Rao just lit a cigarette: "Now that the video footage has covered the records at that time, we have no way to grasp Zhang Qin's final entry and exit monitoring." There was not much circumstantial evidence to draw on during the visit, which only increased suspicions about Hong Wei. ”

The captain agreed with Old Joe's statement. He spit out a smoke ring and shook his head helplessly: "The nature of the case has not been confirmed in time, and our investigation work is very passive. In the shortest possible time, our investigators conducted an in-depth investigation of the family and social relations between Zhang Qin and Hong Wei, and also visited the surrounding neighbors and people one by one. also specially retrieved the video of Zhang Qin's entry and exit from the community before and after his disappearance, and swept it all night, but found nothing. ”

Qiao Zhen recorded the main points, and slowly pondered the direction of this case in his heart. Da Liu raised his hand at this time, and the standard gesture of raising his hand respectfully reminded Qiao Zhen of the three good students in the middle school classroom: "I suggest that Zhang Qin's residence be investigated again, maybe there will be direct or indirect evidence." ”

Qiao Zhen couldn't help but take over the conversation: "Now that Zhang Qin's husband has a relatively large motive for committing the crime, and he has suspicious actions at the time of the possible crime, if we directly investigate the scene, he must be prepared, and he has already hidden more important evidence." From the perspective of criminal psychology, such an action is tantamount to startling the snake, and his psychology is in a further defensive state, but it is easy to cause passivity in the follow-up interrogation. ”

The captain nodded: "Our next move now is to ask the experts of the headquarters to sneak in secretly and secretly investigate the scene." You will need to be consulted before this action is submitted for approval. ”

Qiao Rao just acquiesced to the action. Everyone left in a hurry. Qiao Zhen walked outside the conference room and took a few breaths of fresh air.

She really didn't understand why everyone turned a blind eye to the no-smoking signs posted everywhere, and yesterday, she just wanted to put a printed "smoke-free office" on the door of her permanent archives, but Zhang Chenzhi kindly dissuaded her, saying that it was so easy to isolate herself and appear to be unsociable.

She was tempted to ask why protecting herself from secondhand smoke would be equated with being out of place, but she finally held back. In the days when she returned to China, although she still said things she shouldn't say most of the time, many times, she knew that she didn't ask why, the rules here were like this, and she could only adapt and endure it, and she was powerless to change it.

Whether from the perspective of logic or experience, the residence of Zhang Qin and Hong Wei, in the eyes of the members of the task force, should be the first scene of Zhang Qin's murder. However, there is still a lack of strong evidence for this inference.

A group of investigators on the periphery is searching for septic tanks, garbage bins, and water tanks on the rooftops of residential buildings within three kilometers of the perimeter...... Conduct a focused investigation of areas where corpses and body parts may be hidden. Another group of police officers searched and visited the shops and shops near the community that might have purchased tools for dismemberment and transporting corpses, searching for the slightest evidence. Whether it is direct or indirect evidence, this is the case when solving a case, and when it reaches a certain stalemate, almost everyone is eager to see through the evidence.

Shi Yan and Chen Shijie have been in a state of waiting for orders, Qiao Zhen has not been arranged in the task force, but the door of the archive room is facing the elevator, she glanced at it from time to time, paying attention to the changes on the elevator floor, and preparing to follow to the scene as soon as there is a disturbance.

Next door to the archive room is the conference room of the serious crime team, Zhang Chenzhi passed by her door after the meeting, and when he saw her unrelenting expression, he understood what was going on, and he was especially "gracious" to her to observe and study together. Seeing Qiao Zhen's unbelievable surprise expression, it was almost like he was about to pounce on him to give himself a hug, Zhang Chenzhi hurriedly pretended to look down at his mobile phone, seeing that she didn't pounce, and then waved his hand a little relieved: "Go, go, Shi Yan's master will lead the team, they will set off in five minutes." ”

Under the cover of a team of plainclothes, Lao Qiao's father and daughter rushed to this "first scene" with three members of the technical team. This time the survey was different from the past, time was pressing, although Hong Wei's daughter was in school, but Hong Wei's whereabouts were erratic, and he could go home at any time. The technical team is not only struggling with details, but also racing against time. No one spoke, there was occasional whispered communication, and everyone was busy with their work.
