On The Day Of My 100th Blind Date, I Arrested My Date: Chapter 589 Simple and effective modus operandi

This is also where Chen Yan is most puzzled. After Chen Ziqiang disappeared, he was suspected of being killed. This is a judgment made by Chen Yan and others.

So Chen Yan immediately arranged for Li Yun and others to search all the hidden corners within the surveillance blind spot.

All toilet drains and even septic tanks were spot-checked, but nothing suspicious was found.

Chen Yan even personally checked every classroom in the laboratory building, and found no toilet partitions.

There is no trace of treatment on the wall of the bathroom, and the partition has not been wiped. This statement can be guaranteed to be absolutely correct.

However, now Zhou Haitao said that he killed Chen Ziqiang in the outermost partition of the women's bathroom on the first floor of the laboratory building.

Still beat people to death with a hammer, how is this possible

When a blunt hammer strike kills a person, there is bound to be a lot of blood splatter.

This kind of splattered blood trace, even if it is carefully cleaned and wiped, may leave a clue to be discovered, so how did Zhou Haitao do it?

Not only are there no traces left, even the walls and partitions have no traces of treatment!

"Zhou Haitao, I hope you will be honest. I have personally inspected the bathroom partition you mentioned, and there is absolutely no trace of blood left. You said you killed Chen Ziqiang with a hammer, so why is there no trace of blood?"

"This is very simple, I thought of it a long time ago, so when I tricked Chen Ziqiang out, I covered the bathroom partition with three layers of plastic paper, and even pasted the partition with plastic cloth, just because I was afraid of blood stains Go out and let you find out."

"And I also wore a plastic disposable jacket that day, and I also wore gloves so I wouldn't leave blood stains."

cover with plastic sheeting

Chen Yan was a little surprised, why didn't he expect this detail.

Zhou Haitao's method was really effective. The entire partition was covered with plastic sheeting, and all bloodstains were naturally blocked and would not spray on the front or the partition.

At that time, as long as all the plastic sheets are put away, there will be nothing left in the bathroom except for some **** smell.

In toilets with windows open all the time, the smell will dissipate quickly.

However, in addition to these, there is another problem.

"What about the blood left behind by Chen Ziqiang after he was killed?"

"After I killed him, I cut his aorta open and put the blood in a small bucket."

small bucket

Chen Yan suddenly remembered the monitoring screen of the chef's laboratory on the third floor. Zhou Haitao had asked for leave on the day of the incident, and when he returned to the laboratory, he brought a small bucket and used the contents to make blood tofu.

"So, the material you use to make blood tofu is Chen Ziqiang's blood"

Zhou Haitao nodded: "Blood is not easy to deal with. I was afraid of leaving traces and being discovered by you, so I took it to the kitchen on the third floor to make blood tofu. If you do this, you will definitely not find it.

"How did you deal with Chen Ziqiang's body?"

"Just disassembled it after I killed him that morning, um, and then I took another shredder in the afternoon"

The situation behind is very clear.

Zhou Haitao used a shredder to dispose of the corpses in order to destroy the corpses, and scattered the corpses in batches into the kitchen garbage pile with backpacks.

The kitchen garbage dump where Zhou Haitao threw his body was different from other kitchen garbage dumps. It was not ordinary kitchen garbage from the school cafeteria, but bone fragments left over from raw meat by students in the chef class.

It is a place managed separately, and there is a strong smell of blood, so Zhou Haitao throwing his body in this place will not arouse others' vigilance at all.

"It took me two days to clean everything up and then you guys came.

"Where's the hammer and the grinder?"

"I threw the hammer in the trash, and the pulverizer is in the laboratory on the third floor. After I finished using it, I cleaned it several times with soapy water and used that pulverizer to stir a lot of pork, so no one else noticed it at all. What an exception.

call.

Chen Yan let out a long breath.

There are seven pulverizers in the experiment on the third floor, and Chen Yan has seen them all, but to be honest

, no problems were found.

Yeah, what could be wrong with that.

The shredder will be cleaned up after use, otherwise it will not work next time.

And Zhou Haitao not only washed it with soapy water, but also stirred a lot of pork with it, Chen Yan naturally couldn't find anything abnormal.

"You kill people on the first floor and dispose of the corpses, aren't you afraid of being discovered?"

"It's okay. In those two days, our people had classes on the third floor. Everyone usually went to the toilet on the third floor. They would never come to the first floor. Besides, I put a maintenance sign at the door in those two days, and locked it with a lock. The toilet door is locked."

"No one will know at all, and no one will find out after I have dealt with Chen Ziqiang's body and removed the locks."

"Where's the lock"

"Throw it away, and throw it into the trash together."

The murder weapon appeared to be nowhere to be found.

The garbage dump is cleaned up once a day, and the garbage from two days ago has been cleaned up long ago, but fortunately there are still shredders.

But we can't give up, we still have to look for it as much as possible: "Chaoyang, communicate with the garbage removal company and see if you can find the hammer and lock."

Zhang Chaoyang also knew that this hope was slim, but he still had to give it a try.

What if I find it.

"Where's the plastic sheet you used on the day of the crime?"

"Burn it. On the night I killed Chen Ziqiang, I put all the plastic sheets in my backpack and went to find a place outside the school to burn it."

Well, no trace left.

When Zhou Haitao explained the details of the murder, Li Yun also found evidence.

There are two cameras near the kitchen garbage dump where Zhou Haitao threw his body, one of which is facing the direction of the garbage dump. Although the distance is a bit far, Zhou Haitao's appearance can still be discerned.

At this point, Zhou Haitao's whereabouts from the laboratory building all the way to the kitchen garbage dump to throw his body was fixed by surveillance.

This is because there is solid evidence, plus Li Yun and others found the backpack used by Zhou Haitao in the small cabinet in the dormitory, and the whole case can be considered a thorough investigation.

Since the backpack has been cleaned by Zhou Haitao, UU read www.uukanshu. No bloodstains can be seen on the surface of the com, but there are still some soaked bloodstains in the internal texture.

A day later, the test results of the blood in the backpack and the test results in the garbage dump came out.

Compared with the DNA of Chen Ziqiang's parents, it was confirmed that these bloodstains and tissue components belonged to Chen Ziqiang.

So far, the case of Chen Ziqiang's disappearance has finally been solved!

Liancheng detective team, Zhang Yunhu's office.

"Captain Chen, you are really amazing. A disappearance case suddenly turned into a murder case!"

Chen Yan."."

Chen Yan, who almost spit out a sip of tea, really wanted to leave. Why did I solve the disappearance case into a murder case.

"Team Zhang, Chen Ziqiang was killed in the first place, okay? It's fine if you don't praise me, why do you still complain?"

Spit out the tea stalk in his mouth: "Also, can you change this scented tea?"

"Didn't I also give you a box of Dahongpao two days ago?"

"You still have the nerve to say, just one box is enough for anyone to drink."

Chen Yan: "."

What you say makes sense!

"By the way, the leader is here today to ask you for leave, this is a leave note, please approve it.

Um

After receiving Chen Yan's request for leave, Zhang Yunhu did not hesitate, and signed his name in a hurry: "Where do you plan to go this time to relax?"

Generally speaking, detectives who have completed a homicide case would have taken a vacation to rest and adjust their emotions.

Chen Yan asked for leave, Zhang Yunhu would approve it no matter how many days he asked.

"I haven't made up my mind yet, go back and discuss it with Yun Yi."
