In early spring, the temperature fluctuates.
The corridor where the crime took place was crowded with onlookers, some wearing short-sleeves, sweaters, and pants.
One by one, they stretched their heads to see what was going on with Wang Hui, who was identifying the scene at the door.
It's as if everyone is not an old colleague who has known each other for more than ten years, but a man-eating gorilla that ran out of some zoo.
Suddenly he changed from a human to an animal that can be watched.
But the bright warning line seemed to have barbs on it. No one dared to touch it and everyone stayed away.
Wang Hui hesitated, faced Wang Yishan's question, thought for a while, and pointed to the sofa in the living room.
"Yes...it was from the sofa. She was standing by the coffee table. I was on the sofa. She threw something. I went from the sofa to the kitchen."
"The first stab... was on the edge of the coffee table. She was standing there, thinking that I didn't dare to cut her, so I cut her the first time."
"What happened next, where did the victim go after being chopped?"
"The bedroom, once I entered the bedroom, I chopped her to death."
"Bedroom? Wang Hui!"
Wang Yishan pointed to the blood stains on the entrance door and the edge of the wall: "Then what's going on with the blood stains here?"
"This..." Wang Hui paused slightly while looking at the blood stains: "Oh, I remembered wrongly. She ran from the coffee table to the door first. She wanted to open the door and escape."
"I slashed her again at the door, then pulled her back, and she ran towards the bedroom."
"When she ran away at the door, where did you cut her?"
"The back, I can't remember exactly."
Back?
Wang Yishan's expression changed. He had seen the corpse of the deceased.
There are no wounds on the back at all!
Of course, based on Wang Hui's statement, the victim fled from the coffee table in the living room and turned to the entrance door. Wang Hui chased him from behind, and he should indeed have slashed the victim's back.
However, the reality is that there was no stab wound on the victim's back at all.
The autopsy results of the deceased have come out. The fatal injury was a knife wound that almost cut off the neck.
In addition, the deceased had stab wounds on his chest, arms, abdomen and face, but not on his back.
This shows that the victim was always facing the murderer during the entire killing process, and used his arms to block the murderer's chops.
On the other hand, Wang Hui said that the victim was dragged into the bedroom by him at the entrance door.
But there were no traces of dragging on the ground.
The traces of blood dragging are very easy to judge, and even unprofessional people can see it at a glance.
As for professionals, they can judge the weight, height and degree of injury of the dragged human body based on the area and width of the dragged blood, and the burrs on the edge of the blood stain.
Wang Hui was taken away.
The other party did not tell the truth at all. The murder process he identified was completely different from the process analyzed by blood stains at the scene.
"Old Liu, I'm relying on you here. I'll go back and interrogate Wang Hui personally."
Liu Guodong nodded. Wang Hui was lying at this time, so there was only one possibility.
He did not kill the person, he took the blame for them.
With this direction, it will certainly not be difficult to break through the confession.
But contrary to everyone's expectations, Wang Hui was very uncooperative during the subsequent interrogation.
He insisted that he was the murderer. As for the murder process, Wang Hui believed that he was too nervous when he did it and could not remember clearly.
Water District Criminal Investigation Brigade meeting room.
"Wang Hui is obviously lying!"
Everyone was discussing how to get Wang Hui to tell the truth.
From the analysis of the current situation, it is certain that Wang Hui did not tell the truth.
Failure to tell the truth means that the murderer is someone else.
And if Wang Hui confessed a moment later, the real murderer would be more likely to escape.
"In this way, the interrogation of Wang Hui cannot stop, but we cannot just rely on interrogating Wang Hui and expect him to tell the truth."
Yi Wang
Shan was experienced and wise and quickly formulated countermeasures.
"Supervisor Liu Guodong is following up on the crime scene. If anything is discovered there, we will report it as soon as possible."
"On the other hand, we will conduct a comprehensive investigation of the surveillance video of the community last night."
"Wang Hui's ability to take the blame for others shows that the murderer is very close to him."
"Focus on investigating all the people who came in and out of the community yesterday who are related to Wang Hui!"
Several action groups quickly took action.
On the one hand, they sent people to sort out Wang Hui's interpersonal relationships, and on the other hand, they focused on investigating surveillance videos.
Dongyuan Community is a unit-funded housing built many years ago. The facilities are relatively old. Fortunately, the unit has daily maintenance. There are cameras at the front and back entrances of the community.
But the community has no walls, so the so-called gate does not have much effect.
There is great uncertainty as to whether valuable clues can be captured during surveillance.
The third group of people re-examined the residents of the building where the crime occurred.
"Their family fights every other day. Wang Hui was bullied by his wife."
"I think Wang Hui is really pissed off. It's not easy for his wife to be like this."
"Their family has no children. I heard that Wang Hui is unable to have children. Who knows."
"This house was originally the house of Wang Hui's parents. There was no quarrel with the daughter-in-law. They were kicked out a few years ago. The old couple is renting a house outside."
Neighbors' evaluation of Wang Hui's family is obviously biased in favor of Wang Hui.
As for who else came to Wang Hui's house last night, there is no definite statement.
"There were so many people coming and going in the building, I can't remember clearly."
"Yesterday, when Wang Hui's family started fighting, it was almost midnight. We didn't pay much attention. Their family fought every day..."
Crime scene.
Lu Chuan was collecting the dripping blood stains at the entrance door.
When Wang Hui came to identify the scene just now, Lu Chuan specially observed Wang Hui's hands.
There were no signs of injury.
This is not very scientific.
From the analysis of the situation at the scene, the victim violently resisted when he was chopped.
The bloodstains at the scene were long and narrow, with large intervals of discontinuity, indicating that the murderer used great force when he struck.
Killing is both an easy thing and not an easy thing.
For example, at the scene where Wang Hui's wife was killed, the murderer hacked her several times from the living room to the bedroom before killing her.
During this process, the victim was still resisting violently, and the murderer would most likely be injured.
Especially the hands, after vigorous chopping, the possibility of injury is greater, at least some scratches.
However, Wang Hui's hand was not injured.
This is a doubtful point.
In addition, Lu Chuan also found a drop-shaped blood stain next to the splash-shaped blood stain on the entrance door.
Such bloodstains require relatively still behavior from the source.
Given that the victim was busy running for his life at the time, it was unlikely that he would have left such a blood stain.
Therefore, this dripping blood stain was most likely left by the murderer.
Judging from the height of the drop, it probably dropped from the hand, but Wang Hui's hand was not injured.
So, who left this dripping blood stain?
