First, there is the comparison information about DNA identification results from the technical team.
As expected by Lu Chuan and others, although the DNA identification was successful, there was no comparison with the target person in the information database.
“First, we conducted a comparison in our own city, but there was no comparison here. We also conducted a comparison across the province, but we could not find the target person.”
Lu Chuan nodded.
"It's okay, this is to be expected. You should rest first, and we will listen to the forensic results here."
DNA information identification can often become the most critical clue in solving a case, and it is also the strongest clue.
But the probability of successful comparison of DNA information is too small.
There are many unsolved cases now. In fact, the DNA information about the murderer has been extracted, but the reason why it remains unsolved is that it cannot be compared.
The reason is that generally speaking, the police DNA information databases in various places have too few people.
Generally speaking, there are only six types of people who are forced to collect DNA information.
The first is that DNA information must be collected from criminal suspects during criminal proceedings in accordance with the law.
In addition, relevant departments also require that DNA information be collected for five categories of people. The first category is the parents of missing children.
However, missing children does not necessarily mean that they have been abducted, so in this case they need to be missing, and the collection will only be carried out if the parents of the children request it.
In addition, DNA information must be collected from parents whose children have been confirmed to have been abducted.
Also, the abducted children who have been rescued also need to collect DNA information.
In addition to these three types, there are also begging children of unknown origin or suspected of being trafficked. Children also need to collect DNA information.
Furthermore, when detecting major criminal cases, the collection of DNA information from a certain range of people is also included in the collection scope.
Except for the mandatory collection of DNA information regarding child trafficking, basically most of the information in the DNA database has criminal records.
So if you want to successfully compare DNA information, either the other party is a repeat offender, or it is really difficult to compare.
However, the DNA information database still plays a very important role in solving backlog cases.
There is no doubt about this.
The forensic doctor began to report the relevant situation.
"The deceased woman was 1.55 meters tall, weighed 48 kilograms, and was between 29 and 32 years old."
The forensic doctor turned on the projection, which showed the autopsy report he had just issued.
“Let’s talk about the time of death first. The deceased’s death time should be within a week. And based on the decay and immersion of the deceased, the deceased was not thrown into the Liao River immediately after death.”
"How long?"
Lu Chuan asked.
Will the human body undergo a series of changes after death, including loss of body temperature, rigor mortis, internal decay, etc.
And this change occurs differently in water or in the air.
Forensic scientists apparently determined this information based on these different differences.
"The time should not exceed one day, but the specific time cannot be estimated accurately. The body is soaked in the river water, and then there will be a series of changes inside the body."
The forensic doctor shook his head. , the determination of this kind of incident requires the best forensic doctors, and even the best forensic doctors will make certain mistakes in the judgment process.
Lu Chuan nodded: "Tell me the cause of death." "Yes."
The forensic doctor continued: "After autopsy, it can be determined that the deceased died directly. The reason is Uh, death from cervical asphyxia ”
What appeared on the projector was a photo of the deceased's neck.
“There are traces of bleeding on the neck of the deceased, and judging from the bleeding points on it, it should be that someone strangled the neck with both hands, and then died of suffocation. Judging from the size of the hands, it can basically be The murderer was determined to be a male. "In addition, during the autopsy, it was found that there were bleeding points in the chest diaphragm and lungs of the deceased, which are consistent with the typical characteristics of asphyxiation."
"In addition, we did not detect external water in the deceased's stomach or mouth. From this point, we can also determine that the deceased was thrown into the river after death."
Although it was said that he drowned Both death from strangulation and strangulation are caused by lack of oxygen, but there is a big difference between the two.
The most important thing is that if you drown, there will be a lot of silt in your lungs, stomach and throat.
The forensic doctor has extracted the palm prints that caused strangulation marks on the neck of the deceased.
Judging from the size, this is a male palm.
"Is there a history of childbirth?"
The forensic doctor shook his head: "There are no stretch marks on the deceased's abdomen, and the condition of the pelvis shows that there is no history of childbirth."
"But during the autopsy, we found that the uterine wall of the deceased was too thin, and there should have been an abortion."
"In addition, the victim's lungs were typical smoker's lungs. The approximate attraction is In about 10 years.”
The forensic results provide a lot of information.
The first is the information about the murderer. The other person is a male, but the specific situation needs further analysis. Lu Chuan can roughly judge the height or weight of the other person based on the size of the palm.
But this is only a directional judgment and is not particularly accurate.
In addition, regarding the information about the deceased, the other person had been smoking for about 10 years, and had no history of pregnancy, but had had abortions.
"Is there anything else?"
The forensic doctor nodded affirmatively.
“Yes, during the practice, we discovered a particularly important situation.”
What appeared in the projector were actual flat photos.
The forensic doctor continues the introduction.
"There are slight scars on the lower sides of the deceased's breasts, and there are drainage openings on both sides."
The forensic doctor operated the projector to show the actual corpse walking photos, which are very clear. I saw stitched scars on the underside of both breasts of the corpse.
Wang Zhaokai was stunned: "What is this?"
"Breast augmentation."
The forensic doctor then operated the projection, and what appeared were breast augmentation implants: "The deceased should have had breast augmentation surgery within two months. We took out two breast augmentation implants from the deceased's breasts."
Appeared in the photo It was those two prostheses.
“After the operation, although the scar has healed, there are still drainage holes on both sides. This is because some liquid will flow out when the prosthesis is healing with the fat, so it is necessary Such a drainage port usually disappears and grows and heals in about two to three months, but the fact that the drainage port has not disappeared now indicates that the surgery was performed within half a year. "
"Even, it may be within a month, of course, it may be shorter." (End of Chapter)
