As early as the day they brought the second body back to the Crime Unit from the West Bus Station, they had already caffeinated and stimulated the broken body parts.

And in Shen Figurine's comics, the murderer also injected a drug into the woman's body before dismembering the woman. Of course, now everyone already knows that the woman is the missing Lin Yufeng!

And now the γ-hydroxybutyric acid detected in the blood of two students, although this kind of thing has some medicinal value in medicine, but in this complex society, it is estimated that more people do not use it to treat diseases and save people, but use it as a criminal tool! A low-cost drug to use!

At the same time, drugs containing caffeine, stimulants and this γ-hydroxybutyric acid are the most commonly filed in the police station, and the most common one is also called amnesia water, loss of virginity water, or is called Hong Kong G water!

Now the 5.20 case really involves the problem of drugs again! This is really a matter of touching the whole body, and I really don't know how many appalling things can be involved in this case!

After leaving the People's Hospital, Wang Mo received a call from the group informing them that the results of the recent investigation and examination of various physical evidence had come out, and they hurried back to the group.

This time there are a large number of things sent for inspection, since the test results have come out, then they naturally have to go back to the group to sort out and analyze, this time they must find more substantive clues!

Long Ya listened to Wang Mo talk about the recent investigation in the co-pilot, and she listed all the physical evidence she had collected recently in a long list.

There were two corpses, one male and one female, and all muscles, organs, and bones were separated. The facial reconstruction of the male body is a major undertaking that will not yield results within a week, so the identification of the male victim cannot be completed for the time being, unless there is a glance that the victim is who the victim is.

Two porcelain plates (two porcelain plates containing the head of a corpse at the scene of a murder).

Three hairs (hair with hair follicles, one of which is long and two short. All were found in the second bedroom at the scene of the murder. In addition, the head hair of the male corpse has been shaved bare, maybe he was originally bald, or it may be that the murderer specially dealt with it).

Bed sheets, duvet covers, pillows and other bed items.

A set of school uniforms (this is the clothes brought out from Huang Xu's house).

A small bag of dirt (mud between the cracks in the kitchen floor of the murder case).

Eight colored woven bags.

Finally, there are some samples taken from the kitchen sewer pipe at the murder scene.

Judging from the physical evidence listed by Long Ya, there are many valuable things in it, but Wang Mo said to Long Ya with a disoptimistic attitude, "This time it is estimated that the only useful thing is Huang Xu's school uniform, I just hope that the evidence left in it is enough for us to make more inferences!" ”

"Why? Shouldn't hair give us more accurate information!? Long Ya said.

"Xiao Tan should have told you, she stayed up late yesterday looking for fingerprints on those sheets and other clues, but there were no fingerprints left on them at all. It's just that there are not even two high school students' fingerprints! Wang Mo frowned and said, "Just like what Wei Group said, this murderer's anti-reconnaissance ability is too strong, and he has already cleaned up the scene!" ”

"So it seems too difficult for us to find evidence from the scene! Is that Xiao Guoyou such a person? Long Ya asked suspiciously.

That's right! Is Xiao Guoyou such a person!? Shouldn't he be the kind of thug who just stands on the street and shoots with a gun!? Why spend so much effort to orchestrate these two murders!?

In fact, this is also a huge suspicion that lingers in the minds of all other members of the Serious Crime Team, and it is precisely on this suspicion that the Serious Crime Team has not merged the 5.20 case with the Xiao Guoyou shooting case for a long time.

By the time Long Ya and Wang Mo rushed back to the serious crime team, all the relevant personnel of the 5.20 case, including Wei Zheng, the leader of the serious crime team, had already been in place in the conference room.

"Alright, now the meeting begins. Liu Tan, you say it first! Wei Zheng is the leader of the serious crime team, and the meeting is naturally presided over by him.

"I am mainly responsible for the collection of fingerprints and blood samples at the crime scene." Liu Tan is now wearing a round-framed glasses that she basically doesn't wear much on weekdays, she supported the frame with her index finger and said, "From the sheets and bedding brought out of the apartment where the two high school students were found, except for some sweat and oil secreted by the skin, there were no traces of fingerprints. ”

"It's the same with the doorknobs at the site, all of which have been wiped with cotton cloths. I found cotton thread residues on the kitchen doorknob. ”

"As for the two plates containing the heads of the corpses, there are no traces left on the plates containing the women's heads. However, two finger marks remained on the porcelain plate containing the male head. ”

"Finger marks!?" As soon as Liu Tan talked about finger marks, the eyes of everyone present lit up, could it be said that there was already a breakthrough clue!?

Liu Tan looked at the expectant eyes of everyone in the group, she sighed helplessly and said, "Finger marks, not fingerprints." The finger marks left on that plate were the finger marks of PVC gloves left by oil stains. According to the size of the finger marks, it can be roughly inferred that the height of the owner of the finger marks should be between 1.68 and 1.8 meters. That's all for my side of the investigation! ”

The reason why Liu Tan was able to determine that the finger marks were left by PVC gloves was because the finger marks remaining on the porcelain plate were only two clear finger grease marks, but there were no lines left on them, and only close-fitting PVC gloves could have such an effect.

"Well, this is a very breakthrough clue, and with this clue, we can lock down the height range of the murderer." Originally, Wei Zheng and the others in the group didn't have much hope for Liu Tan's investigation, but obviously the report given by Liu Tan was enough to surprise the group.

"Xiao Liu, what are the results of the samples sent to the metrology center for monitoring?" The position looked at Wang Mo's assistant Xiao Liu again.

The mud and dirt, water pipe samples, hair and school uniforms of high school students collected from the scene were all sent by Xiao Liu to the H Provincial Metrology Research Institute for testing yesterday.

There are the most advanced relevant testing instruments in the province, which can quickly help the police determine some effective clues.

"Well, after comparing the DNA samples carried in the three hairs with the existing witness pool, it was determined that the long hair in them belonged to the deceased Lin Yufeng, and the two short hairs belonged to high school student Huang Xu."

"A large amount of blood residue was found in the mud extracted from the kitchen, and the match with Lin Yufeng's DNA was 90%."

"Only animal fat residues were found on the water pipe samples."

"Finally, blood residue was found on the clothes of high school students......"
