"I think it was the murderer who choked the neck of the deceased and suffocated Zhang Yanhong to death."

Jiang Qingrui used the picture provided by the death sharing, and then combined it according to her own inference, "The murderer was afraid of leaving his fingerprints on his neck, and he was worried that he would not be able to wipe them clean, so he simply cut them off without doing anything else to ensure that nothing went wrong." ”

There are no loopholes in her statement, murderers with no experience in killing can easily act impulsively, and it is not surprising that some outrageous things happen.

"The time of death of the deceased was around two o'clock."

Jiang Qingrui forgot that she didn't say it just now, and added it again.

Xu Shu thought for a moment after listening, "In order to prevent the police from extracting fingerprints, it also makes sense......"

But the keys can't just be guessed, and substantial evidence must be found to prove it.

"Do you remember, the surveillance in the corridor on the first floor has not been seen since midnight?"

Xu Shu suddenly remembered this matter, if the time of death was after two o'clock, how did the novice enter the hotel.

"Flip through the window?"

Jiang Qingrui felt that there were many ways to sneak into the deceased's room silently, and she could think of no less than five of them, and if the monitoring was not illuminated, there was no need to worry about it.

And the murderer deliberately hides his tracks, which is not difficult for him.

"Look at it."

Xu Shu is a man of action, and he called Jiang Qingrui to get up and go to the hotel.

From a distance, the environment of the hotel is not good, and it is not surprising that there is no surveillance on the street.

After Xu parked, he searched along the ground around the hotel, and Jiang Qingrui followed him to observe the wall to see if there were any suspicious footprints.

"Got it."

Xu Shu stopped and said to the ground.

Jiang Qingrui took a few steps forward, and sure enough, she saw a few shallow footprints on the ground.

Was the murderer so careless?

Jiang Qingrui judged before that he did not forget to cut off the fingerprints on his skin, but he didn't expect the murderer to fall on his heel on the shoe print, and began to wonder if there was a problem with his careful and cautious thinking about the murderer.

But no one gave her an answer.

"I brought tools."

Jiang Qingrui opened the backpack she was carrying, and was glad that she had a set of equipment when she went out, otherwise she would have to turn back now, so it wouldn't be troublesome.

"No fingerprints found."

Jiang Qingrui inspected it up and down, and didn't even let go of the windows and walls.

"But I found fiber."

Jiang Qingrui picked up a few fibers with tweezers and put them into a transparent sealed bag to identify, "The material is cloth, it should be that the murderer turned over with gloves on, and he didn't pay attention to it and left it in the gap in the window." ”

The inn is fully cleaned when guests check out, so it can only be left while the deceased is staying at the house.

Zhang Yanhong's luggage obviously did not have cloth gloves, only traces left by the murderer.

Although there are no fingerprints, at least it is confirmed that the murderer came in through the wall.

The two returned to the police station wearing fibers, and when they walked to the door, they saw a middle-aged man talking to the officer.

"This is Zhang Yanhong's ex-husband."

The police officer saw the two people coming back and said to the man, "These two are the police officers in charge of Zhang Yanhong's case, and I can tell them the details." ”

"I just have something to ask you."

Xu Shu took the man to the empty room, and the other party sat upright, calmly waiting for an answer.

Jiang Qingrui observed the man's expression on the other side, and after learning that his ex-wife died, he did not reveal a sad expression. Since you choose to divorce, it means that you may be emotionally exhausted, and it is more natural that you can't empathize.

Thinking like this, Xu Shu had already begun to question.

After understanding, the reason for the divorce of the two people was that the husband committed domestic violence, and the man did not hide it, and told the cause and effect in a sparse and ordinary tone.

Just looking at his appearance, he is honest and honest, and it is hard to imagine that this person often drinks heavily, and frequently beats his wife when he is drunk, and uses unsightly expletives to carry out personal attacks.

So Zhang Yanhong couldn't bear it anymore and decided to divorce, leaving her son to her ex-husband.

Jiang Qingrui noticed a small reflection at the door, eavesdropping on their conversations, and immediately judged the identity of the person who came, and got up to open the door.

A young face appeared below, Jiang Qingrui pretended to have just seen it, and led the child to another room, "Are you Zhang Yanhong's child?" Your dad is still coming out in a while, so I'll take you to rest first. ”

When the child heard his mother's name, he also knew that the police could be trusted, and besides, the sister who was talking in front of him was very beautiful, so he was naturally willing to follow.

"Was there anything bad about your mom and dad when they were together?"

Jiang Qingrui wants to ask from children, because of the young age of children, they often suffer from neglect, but many people don't know that children are more observant and will notice points that adults can't find.

"After my dad hit my mother, my mother would hold her phone and cry."

The child observed all this, although every time his mother was beaten, he would let her hide in the room, but every time he would secretly open a crack in the door, and in the long run, he knew his mother's movements after each beating.

"I want to help my mother, but my father is so fierce......"

The child pursed his lips, tears welled up in his eyes, he didn't know who to talk to about this kind of thing, he kept it in his heart.

"You're already great, and your mom will definitely praise you in the future."

Jiang Qingrui touched the child's head and gently comforted.

After Xu Shu finished, she took the child to her father and watched the two leave the police station before she spoke.

"Every time Zhang Yanhong is beaten, she cries with her mobile phone."

Xu Shu didn't expect Jiang Qingrui to get a new clue in just ten minutes, looked at her with some surprise, and randomly understood who the person who provided the clue was.

"Pretty good."

He praised and asked people to bring Zhang Yanhong's mobile phone.

If she hadn't gone out, KK would definitely be in charge of the investigation of the mobile phone, Jiang Qingrui's mind wandered for a moment, she missed everyone a little.

Fortunately, it was not difficult to do this time, just to retrieve the call records, Xu Shu rummaged for a while and found that Zhang Yanhong frequently contacted a phone number.

Tell the police about the incident, and the other party immediately sent professional personnel to investigate.

As long as you enter the phone number, you can find the owner of the number.

"It shows that the other party's name is Wang Kai, a local person."

"Summons immediately."

Xu Shu knocked on the table, and the police responded and immediately contacted him.

Not long after, someone ran into the police station in a hurry, "Someone is looking for me." ”

Wang Kai thought about it for a long time, but he didn't know what he had done.

"Follow me."

Jiang Qingrui was waiting in the hall in advance, for fear that the other party would not come and notice that something was wrong.

Thankfully, things are going well so far.
