The Maotong District Public Security Bureau, the office building belonging to the Criminal Investigation Brigade, the large conference room, Yu Chen, Yuan Youchong and other XGJGs, as well as some traffic police officers from the high-speed brigade are all gathered here. \ It was ten o'clock at night, the highway had already been reopened, and it was dangerous to stay at the scene, and the scene had already been surveyed, so they simply moved here.
As for Zhou Qianxin and her intern, they carried the corpse back to the detachment.
Compared with the criminal investigation brigade, the forensic department of the detachment is undoubtedly more advanced and complete in terms of equipment.
A simple autopsy is easy to say, it mainly depends on the professional ability level of the forensic doctor, not to mention the dissection room of the brigade, if the conditions do not allow, the funeral home will still be autopsied.
Not to mention, in the past two years, how many autopsies Zhou Qianxin has had were done in a room temporarily vacated by a police station in a suburban county or a relatively remote mountain village.
But this time it was different, Zhou Qianxin really had to go back to the detachment, extract the dandruff tissue from the victim's fingers, hand it over to the genetics laboratory for testing and draw a map of DNA feature points.
In that case, it's better to go back directly.
After all, in addition to the detachment, there are less than half of the criminal investigation brigades or public security bureaus in Xin'an City that have genetics laboratories for testing and drawing DNA mapping, and unfortunately, the Maotong Public Security Bureau is not one of them.
It's just that the dissection is quite complicated, and it is not just a pig-killing dissect.
Three corpses, as is customary, to say the least, were busy all night.
In other words, at tonight's regular meeting, Zhou Qianxin was unable to attend, let alone report the autopsy findings.
However, the on-site autopsy conclusions, Yu Chen, Yuan Youchong and other important xgjg already know, and whether she participated in tonight's regular meeting or not had no impact.
As for the regular meeting, there is actually nothing to say, everyone is responsible for the work and harvest, in fact, they know each other, and the exact harvest of Xi Yu Dailing's criminal investigation brigade is not very clear, but they also understand that they also have no breakthroughs.
The regular meeting is just a systematic summary, and at the same time the XGJG is scheduled for the next day's tasks, so it ends quickly, and everyone rests.
Early the next morning, Yu Chen was eating breakfast when he received a call from Zhou Qianxin.
"Team Yu, the autopsy results are out, the fatal wound is clear, and the characteristics and parameters of the murder weapon are roughly inferred according to the morphological characteristics of the wound.
As for the rest, there is no deviation from the conclusion of the autopsy at the scene. ” "Okay."
Yu Chen answered, and at the same time picked up a wonton from the bowl, but he didn't stuff it in his mouth for the first time, and asked first: "Is the DNA test result out?"
"From the point of view of time, as long as DNA can be detected, it should be drawn" Zhou Qianxin replied on the phone: "I'm not sure about the specifics, I'm still in the autopsy room at this time, just finished the autopsy and sent the victim's body to the freezer for storage, I'll ask later, and then call you." ” "Okay."
Yu Chen raised his eyebrows, said a few words of hard work and the like, hung up the phone and put it on the table, and stuffed the wontons into his mouth.
After about ten minutes, he finished the wonton soup.
Yuan Youchong happened to come over with a bowl of mixed noodles, and when he saw him put down the bowl, his eyes widened slightly: "Isn't it Lao Yu, this white water is the same, at most a wonton soup with a little salt and chicken essence or something, you can actually drink a fine light."
He sighed, and was about to answer, when the mobile phone thought about it again, and after glancing at the caller ID, he shrugged at Yuan Youchong, and then connected the phone: "Xiao Zhou, how is it?"
"DNA was detected between the fingers of the three victims."
Zhou Qianxin's voice sounded a little excited: "In addition, I will tell you good news, one of the DNA has found a counterpart in the gene pool, and directly locked the target identity."
"Oh" Yu Chen was a little surprised, in recent years, although the fingerprint bank and gene bank have been established one after another, but compared with the fingerprint bank that has been greatly improved by binding the ID card, the construction of the gene bank has undoubtedly just started, and it is extremely incomplete.
Actually, it's easy to understand: The cost and difficulty of collecting fingerprints and genes are not the same, and collecting a fingerprint requires a set of equipment, which can be scanned and uploaded for storage in a few seconds.
However, to collect genes, it is necessary to obtain biological samples that meet the requirements, and it is necessary to have professional forensic doctors and supporting equipment to test and calculate for a long time, at least a few hours.
As a result, the genetic testing and identification of civil and relatively less important cases still have to queue up for a long time.
In addition, there is a secondary reason: most people are not averse to the country's initiative to collect fingerprints, and when they apply for an ID card, they listen to the household registration police, and obediently press their fingerprints on the collection equipment; However, if DNA is collected, there may be many fewer people willing to cooperate.
After all, while recently lost hair with hair follicles, deep-cut nails, and oral epithelial cells can all be used as samples, blood sampling is still the most popular and convenient Moreover, not to mention organizing and promoting the popularization of gene storage, even if a few citizens take the initiative to go to the grassroots police station to put forward gene storage due to various needs, the police in most units are either confused, or they are troublesome and find excuses to prevaricate.
Even if blood is taken, it is likely to be spoiled directly in the police station For these guys who dismantled the stage, Yu Chen couldn't do anything except be angry with them.
All in all, to a certain extent, the gene pool often plays no role in the detection of criminal cases, especially the initial investigation, and can only be used for investigation and identification in a small range after locking the scope of suspects, as well as important evidence when the case is finally closed.
Therefore, Zhou Qianxin said that when one of the suspects' samples found a counterpart in the gene pool, Yu Chen was quite surprised.
Immediately afterward, he felt a burst of joy that he had found a counterpart in the gene pool, which meant that he had directly locked on a fairly specific and exact suspect, which could save a lot of time in the initial investigation.
Even, maybe you can skip the initial investigation work and enter the later stage of evidence collection.
Thinking of this, he hurriedly said: "In this way, the murderer has been identified."
"So to speak," he heard Zhou Qianxin take a breath, and then heard her say: "The target has several previous theft convictions, so he took a blood sample and entered the gene bank earlier."
"Forget it, I'll just say the result, the suspect's name is Wen Chengze, male, 24 years old, from Daxing Village, Yixing Township, naked height of 1.69 meters, recorded weight of 57 kilograms."
"What does his height and weight data mean within the margin of error between the height and weight of one of the three suspects that we and the Trace Examination Department have speculated?
I don't need to say more
