Attending ex-girlfriend's wedding, arresting the groom's officer on the spot

First, the technical team provided comparison information on the DNA identification results.

As Lu Chuan and others expected, although the DNA identification was successful, there was no match to the target person in the information database.

"We first conducted a comparison in our city, but there was no match in the city. We also conducted a comparison across the province, but we still couldn't find the target person."

Lu Chuan nodded.

"It's okay. This is to be expected. You guys take a rest first. We'll listen to the forensic doctor's findings."

DNA information identification can often be the most critical clue in solving a case, and it is also the most solid clue.

But the probability of successfully matching 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 the case remains unsolved is that it cannot be compared.

The reason, generally speaking, is that there are too few people in the DNA information database of the police in various places.

Generally speaking, there are only six categories of people whose DNA information is forcibly collected.

The first is that DNA information must be collected according to law from suspects during criminal proceedings.

In addition, the relevant departments require that DNA information must be collected from five categories of people. The first category is the parents of missing children.

However, a missing child does not necessarily mean that he or she has been abducted, so in this case the data must be collected only if the child’s parents request it.

In addition, the parents of children who have been confirmed to have been abducted will also have their DNA information collected.

In addition, DNA information needs to be collected from abducted children who have been rescued.

In addition to these three types, there are also beggar children of unknown origin or suspected of being abducted, and children also need to collect DNA information.

Another thing is that when solving major criminal cases, it is necessary to collect DNA information from a certain range of people and include it in the collection scope.

Apart from the mandatory collection of DNA information regarding child trafficking, basically most of the information in the DNA database is about criminal records.

Therefore, if you want to successfully match DNA information, either the other party is a repeat offender, or it is really difficult to match.

However, the DNA database still played a big role in solving unsolved cases.

There is no doubt about this.

The forensic doctor began to report the relevant situation.

"The deceased is a female, 1 meters tall, weighs 55 kilograms, and is between 48 and 29 years old."

The forensic doctor turned on the projector, and on it was the autopsy report he had just issued.

"Let's talk about the time of death first. The deceased should have died within a week. And according to the state of decay and immersion of the deceased, the deceased was not thrown into the Liaohe River immediately after death."

"for how long?"

Lu Chuan asked.

The human body undergoes a series of changes upon death, including loss of body temperature, rigor mortis, internal decay, etc.

The changes that occur in water or in the air are different.

The forensic doctor apparently determined this information based on these different differences.

"It should have taken no more than a day, but the exact time cannot be estimated accurately. The body was put into the river to swell, and then a series of changes occurred inside the body."

The forensic doctor shook his head. It requires the best forensic doctor to judge such incidents, and even the best forensic doctor can make mistakes in the process.

Lu Chuan nodded: "Tell me the cause of death." "Yes."

The medical examiner continued: "After an autopsy, it can be determined that the direct cause of death of the deceased was asphyxiation due to cervical suffocation."

What appeared on the projector was a photo of the deceased's neck.

"There are traces of bleeding on the victim's neck, and judging from the bleeding spots, it should be that someone strangled his neck with both hands, which led to suffocation. Judging from the size of the hands, it can be basically determined that the murderer is a man."

"In addition, during the autopsy process, it was found that there were bleeding spots on the deceased's chest diaphragm and lungs, which are all consistent with the typical characteristics of death by suffocation."

"In addition, we did not detect any external water in the deceased's stomach or mouth, which also confirms that the deceased was thrown into the river after death."

Although both drowning and strangulation are caused by lack of oxygen, there are still big differences between the two.

The most important thing is that if the person died by drowning, there would be a lot of mud and sand in the lungs, stomach and throat.

The forensic doctor has already extracted the palm prints that left strangulation marks on the victim's neck.

Judging from the size, this is a male's palm.

“Any history of childbirth?”

The forensic doctor shook his head: "The deceased has no stretch marks on her abdomen, and the condition of her pelvis shows that she has no history of childbirth."

"But during the autopsy, we found that the uterine wall of the deceased was too thin, and she must have had an abortion."

"Also, the victim's lungs were typical of a smoker's lungs, probably aged around 10 years."

The forensic identification results provided a lot of information.

First of all, there is information about the murderer. The other party is a male, but the specific situation still needs further analysis. Lu Chuan can roughly judge the other party's height or weight based on the size of the palm.

But this is only a directional judgment and is not particularly accurate.

In addition, regarding the deceased's information, she had been smoking for about 10 years and had no history of pregnancy, but had had an abortion.

"Anything else?"

The medical examiner nodded affirmatively.

"Yes, in the process of practice, we discovered a particularly important situation."

What appears in the projector is the actual flat-lying photo.

The forensic doctor continues his introduction.

"The deceased had slight scars on the underside of both breasts and drainage holes on both sides."

The forensic doctor operated the projector to display the actual photos of the corpse. It was very clear that there were sutured scars on the lower side of the breasts.

Wang Zhaokai was stunned: "What is this?"

"Breast augmentation."

The forensic doctor then operated the projection, and a breast implant appeared: "The deceased should have had a breast augmentation surgery within two months. We removed two breast implants from the deceased's breasts."

The two prostheses appeared in the photo.

"After the surgery, although the scars have healed, there are still drainage holes on both sides. This is because some fluid will flow out when the prosthesis heals with the fat, so such a drainage hole is needed. Under normal circumstances, such drainage holes will disappear and heal in about two to three months. The fact that the drainage holes have not disappeared now means that the patient must have had the surgery within six months."

"It may even happen within a month, or even sooner." (End of this chapter)
