I'm in a mental hospital, Bai Fumei forces me to be her boyfriend

Wang Ze and Li Xiangbin returned to the living room.

Soon, the police officer from before came back

"Team Li, the protective net of the residents opposite the door is very strong, with no signs of damage or even looseness."

The police reported the report.

Li Xiangbin nodded and said:"Okay, I know, go and do your work."

"yes.

Li Xiangbin looked at Wang Ze beside him and said,"It seems that one possibility has been ruled out.""

After the neighbor across the door killed the person, he left through the window of the deceased's house, then climbed through the window and returned to the opposite side.

The possibility of this behavior can be ruled out.

But it does not mean that the suspicion of murder is ruled out.

Wang Ze nodded in agreement.

At this time , Wang Xiaotong came back.

It was her that Li Xiangbin was waiting for, and he quickly asked:"How is it?""

Wang Xiaotong said:"Judging from the monitoring time, there was a gap of fifteen minutes between the time the victim's child left and when he returned. Hearing this

, Li Xiangbin was immediately surprised:"So short?""

Wang Xiaotong nodded in affirmation.

Li Xiangbin:"What about the others? Did the surveillance capture anyone suspicious?

Mentioning this matter, Wang Xiaotong said:"The surveillance captured a young man entering and leaving the unit.""

"The picture is very clear and I have found the person."

After saying that, she opened the computer in her hand and called up a person's information.

Fan Kaiyu, male, 21 years old, a junior at Yuncheng University.

Wang Zedao:"Little boy, let me take a look at the surveillance screen."

Wang Xiaotong said:"Okay, I have copied the monitoring"

"At this."

As she said that, she called up the surveillance screen.

The surveillance showed that Fan Kaiyu first entered the unit building during the time of the crime.

He left five minutes later.

In terms of the time of the crime, it was consistent.

After watching the surveillance, Wang Ze said:"It doesn't look like he just killed someone."

Fan Kaiyu in the picture is looking at his mobile phone while walking, and occasionally laughs happily.

It is difficult to connect this young man with the murderer who just cut the throats of a couple.

But of course, one cannot look at the surface when investigating a case.

Li Xiangbin said:" Just ask."

"Who is that? Call Fan Kaiyu over and ask why you are here and which household you are looking for."

"Yes, Captain. After giving the instructions, he looked at Wang Xiaotong and continued to ask:"Have the surrounding surveillance cameras checked?""

"We just discovered that the protective net in the master bedroom was damaged."

"The murderer might have jumped out of the window and left.

Wang Xiaotong shook his head and said:"The nearby surveillance cameras can only capture the entrance of the unit and a few main roads.""

"The bedroom you mentioned is facing south and has a lawn with no surveillance."

Hearing this, Li Xiangbin was not disappointed.

After handling cases for so many years, situations without surveillance have happened from time to time.

No matter how powerful Skynet is, it is impossible to cover all blind spots.

Therefore, as long as criminals with some anti-detection capabilities are dealt with It’s more difficult to get up

"The murder weapon?!"

At this moment, Song Ting's voice suddenly came, with surprise.

Several people turned their heads.

At this time, Song Ting was standing in front of the corpse.

She was holding a handful of things that came out of nowhere. Knife.

Judging from the shape, it looked like a fruit knife.

Seeing this, Li Xiangbin and others walked over quickly

"what's the situation?"

"Where did it come from?"

When they rushed to the crime scene before, they didn't find any murder weapons around the scene.

Why did a knife appear out of nowhere?

Song Ting pointed at the female victim and said:"This knife is in her top."

"I just found it when I checked"

"The blood remaining on it has traces of wiping"

"Jacket?"

Li Xiangbin approached and took a look at the female victim.

The clothes she wore were looser and there was room at the collar. She could indeed throw a knife in.

"After the murderer finished killing the person, he threw the murder weapon into the deceased's clothes?"

"What is this operation?"

"What about Bao Qu? Let's see if there are any fingerprints on it."

After the words fell, Bao Qu, who was investigating the scene, hurried over.

"give it to me."

He took the knife from Song Ting's hand.

Fingerprint extraction is a basic operation for technicians.

At this time, Wang Ze began to observe the two victims at close range for the first time. He had been talking to Li Xiangbin before.

His gaze started from the wound at the victim's throat and slowly moved downwards.

Top, pants, shoes.

Nothing was missing on the surface.

After a while, he gently opened the female victim's clothes. She was slightly stunned. Then, he said:"The murderer has a very strong psychological quality. It may not be the first time he kills someone."

As soon as these words came out, Li Xiangbin and Wang Xiaotong were immediately shocked.

"What?

Li Xiangbin looked at Wang Ze and said,"Why?"

Wang Ze opened the top of the female victim and said,"The blood residue here is from wiping the fruit knife.""

"This shows that the murderer’s order of killing is to kill the male first and then the female."

"After killing the woman, he calmly wiped the fruit knife with the deceased's shirt."

"Finally, he threw it into the deceased's shirt."

"The whole process was very calm, it can be said that there was no trace of nervousness."

"Do you think this is your first time committing a crime?"

After listening to Wang Ze's words, Li Xiangbin frowned deeply.

Judging from the wiping marks, this is indeed the case. It is conceivable that after the murderer cut the throats of two people, he actually stayed there and had the leisure and grace to wipe the murder weapon. The blood on it has no purpose.

It's just wiping the blood very calmly. It

's like appreciating your own masterpiece.

What kind of strong psychological quality does it take to do such a thing?

"Where is Fan Kaiyu? Have you been called?!"

After a moment of silence, Li Xiangbin turned around and shouted.

If Fan Kaiyu has nothing to do with this case

, then the entire unit of thirteen households must take compulsory measures to investigate thoroughly!
