Chapter 359 DNA Information to Determine Identity (Normal and 1500(1/3)
Chapter 359 DNA information determines identity (normal updates and 1500 monthly tickets are issued together!)
Insert steel nails from Baihui point?
Chen Yan has only seen this kind of murder method in novels before, but this is the first time he has encountered it in reality.
This case...
It's a little strange.
Why did the murderer use this method to kill people?
Although the cause of death of the victim has been found, it is not very helpful to the investigation and handling of the case at present.
The steel nails found in the body of the deceased were about 5 cm long and were rusted and could be bought at any hardware store.
It is very difficult to determine the identity of the murderer by tracing the source of the steel nails.
Because the cause of the deceased's death was strange, Chen Yan followed Wang Meng to the autopsy room.
The steel nails have been removed from the head of the deceased and placed in a tray.
Chen Yan used tweezers to pick up the steel nails and opened the visual gene lock to observe carefully.
The steel nails are covered with rust, and there are marks of knocking on the nail hat.
"Have fingerprint information been collected on the nail?"
Wang Meng shook his head: "We carefully checked the steel nails and found no useful information."
Chen Yan nodded, which was also within his expectations.
The crime scene was not the first scene where the deceased was killed.
During the process of throwing the body, the murderer left no trace.
And from the current perspective, the murderer chose to throw the body in the Taipingfang self-built house area, with the fundamental purpose of using demolition and construction to destroy the body.
It was only because of the homeless Wu Guizhong's accidental discovery that the existence of the corpse was exposed.
Now only waiting.
Wait for the identification of the deceased to be confirmed, and there are also visits to residents around the self-built house area.
Putting down the steel nails, Chen Yan walked to the dissection table: "Are there any signs of sexual assault in the deceased during his lifetime?"
Wang Meng nodded affirmatively: "We collected residual substances in the deceased's body."
"At the same time, the residual substance was collected in the mouth and chest of the deceased."
"DNA information analysis is now being done."
Wang Meng looked at the time on the watch: "In about two more hours, the DNA information can be analyzed."
"Okay, let me know as soon as you have news."
"Yes, captain."
...
4 pm.
Regarding the determination of the identity of the deceased, Zhang Chaoyang has not yet sent any news.
Zhao Bing was responsible for visiting and investigating residents around the self-built house area, but there was no valuable information sent back.
However, the DNA information collected from the deceased has been tested.
Wang Meng turned on the projector and started reporting.
"Captain, we analyzed 4 DNA information in total," he said.
Four types?
Chen Yan's expression was slightly stunned. How could there be so many DNA information?
Did the deceased have been insulted one after another during his lifetime?
Considering the appearance of the deceased, this possibility exists.
However, the clothes on the deceased were not messy and had no special wrinkles.
If it's a turn of insults...
Did the murderer put clothes on the deceased again?
"Report in detail."
Wang Meng nodded and began to report: "The residual substances collected in the body of the deceased have analyzed three kinds of DNA information."
"The substance collected on the chest analyzed two types of DNA information."
"A DNA information was discovered by substances collected in the oral cavity."
The projector lists the description of all DNA information separately.
"The three types of DNA information found in the lower body overlap with the two types of DNA information on the chest."
"But the DNA information in the oral cavity does not coincide with all other DNA information."
"That is to say, the deceased had had close contact with four men in a short period of time."
Have had close contact with so many men in such a short time...
Could it be that the identity information of the deceased is the young lady who never returns home at night?
However, it's not very similar.
The deceased has a good appearance, fair skin and a good figure.
In particular, Chen Yan noticed the perfume used on the deceased at the scene.
Chen Yan once smelled the smell of this perfume on Shen Yunshu.
Although Chen Yan doesn’t know the specific brand of this perfume, the perfume used by Chen Yunshu is definitely not cheap.
How could a young lady who works in a dusty job use such an expensive perfume?
And the clothes worn by the deceased.
Although Chen Yan doesn’t know the specific brand of the clothes, the material of the clothes is very good.
It's not a bargain at first glance.
In addition, the deceased had a ring on his right ring finger, a bracelet on his left hand, and a necklace on his neck.
If you analyze these details...
The economic conditions of the deceased should be very good.
It seems that it shouldn't be a fair woman.
Chen Yan shook his head.
There is still too little information at present to determine the identity of the deceased.
"Wang Meng, hand over the DNA information to Wang Wugang."
"Let him compare it in the DNA information database to see if he can find out."
"yes!"
In the office, Chen Yan was paced back and forth.
A young woman had intimate contact with four people in a short period of time.
After being killed, he was thrown into the self-built building area late at night.
The rings, necklaces and bracelets on the body disappeared.
On the surface, it is very likely to be a case of robbery and murder.
But generally speaking, robbery and murder are mostly passionate crimes.
Either make a temporary intention, or follow the murder and then commit robbery.
There will definitely be traces of crime at the scene of the crime.
It is unlikely to kill people with steel nails.
Therefore, the loss of important property on the deceased is likely to be intentionally forged by the murderer.
In order to create the illusion of robbery and murder.
Of course there is another possibility.
The deceased is engaged in the dust industry.
After the transaction is completed, the other party has no money to pay for prostitution and is murderous.
After killing the victim, he looted all the property of the victim.
call……
Spit out a long breath of turbid air.
