Using science to assess the death of Cat Tuong

Associate Professor, Dr. Nguyen Van Ha, Deputy Director of the Center for Legal Biochemistry, Ministry of Public Security, said that in order to determine that the body of Huyen inspection agency must take DNA samples from her parents and victim's child. .

After 10 months of waiting, hopefully, at times, it seems that everything will be arranged when the victims of Le Thi Thanh Huyen, the victim of the incident at the Cat Tuong salon cannot be seen, in the end, Family, investigating agency and public opinion were also able to breathe. On the afternoon of August 5, the information of the body of Le Thi Thanh Huyen was found by Colonel Vo Hong Phuong, Deputy Head of the Criminal Department of Hanoi Police. The question of public opinion is based on which basis to confirm exactly the body of the victim Huyen, when the corpse was found and brought to the examiner was decomposed, the body parts were removed. Associate Professor, Dr. Nguyen Van Ha, Deputy Director of the Center for Legal Biochemistry, Ministry of Public Security has explained this.

Reporter: Can you tell us what basis the police are based on to confirm that the body is victim Le Thi Thanh Huyen?

- Associate Professor, Dr. Nguyen Van Ha: After identifying the victims floating on the banks of the Red River in Van Duc commune, Gia Lam district, TP. Hanoi, the police investigation agency of Gia Lam district collected samples, sent to the Criminal Science Institute to conduct DNA inspection. As we all know, DNA testing is one of the very accurate tools to help us traceable human beings, identify blood relationships and can solve other requirements. related to DNA.

In this case, after receiving the decision to solicit specimens and specimens is a piece of bone collected from the floating body on the banks of the Red River in Van Duc commune, Gia Lam district, Hanoi, and the Criminal Science Institute of them I conducted an assessment with the aim of determining if the bone sample of a woman floating on the banks of the Red River was of Mrs. Le Thi Thanh Huyen, the victim of the case at the Cat Tuong salon.

I am the one who is directly responsible to work with you to evaluate the bone to identify the victims.

After 3 days we have obtained the initial result that the bone sent to the assessment is by a person who is related by mother and daughter to Mrs. Nguyen Thi Hien - mother of Le Thi Thanh Huyen. Because this is a very important case and causes a lot of annoyance to the public opinion, we do not rush to immediately return the results but need to determine accurately and objectively before answering the results. For that reason, we asked the investigation agency of Gia Lam district to collect samples from Mr. Le Van Vien - the father of Le Thi Thanh Huyen and collect samples of Nguyen Huu Hoa, the biological child of Le Thi Bar suspension. After 4 days of follow-up assessment, we identified a bone sample of a victim who is the offspring of Nguyen Thi Hien and Le Van Vien. At the same time, we also identified the victim as the mother of Nguyen Huu Hoa. On that basis, we make conclusions to send to the investigating agency, and the investigating agency will definitely determine that this is the body of Ms. Le Thi Thanh Huyen.

Once the body was identified as the victim Le Thi Thanh Huyen, can we examine the body to determine the cause of death?

- In fact, to determine the cause of death of a body it depends on many factors. It may be the victim's condition if the victim is intact, we can identify the cause of death more easily. In the case of the body we discovered, it was not intact, most of them only bones. Determining the cause of bone death will be more difficult. The problem is to determine if there are any lesions on the bone and the bone damage caused by the tool. That it is for medical practitioners, they will have to conduct a piece of bone assessment to see if there is any damage.

One of the most important things about this case in my opinion is to determine if the corpse dumped into the river, when thrown into the river is alive or dead, that is, to determine the time of death before or after being thrown into the river. To solve this requirement, for corpses and bones, it is very difficult. But with the development of modern science today, I think, may be able to answer some requirements as I just said.

Usually, with the body after many days can still assess the body's injuries and after how many days no longer able to assess, sir?

- In fact the body that can assess the cause of death, assessing the body's injuries depends on the condition of the body. If it was left in a very long time, the body's software organizations were rotting, then identifying the vulnerabilities of the software was almost impossible. Only bone lesions can be identified, but to determine this, there must be an external force on the bone to cause bone damage.

In the case of victim Le Thi Thanh Huyen, as I said, forensics must study all the remaining bones in order to determine the impact on bone. Time depends on many factors especially in tropical countries such as Vietnam, high humidity, hot and humid temperature, weather plus insects decompose very quickly, but decompose corpses like that then identifying vulnerabilities will be difficult.

By finding the body of Le Thi Thanh Huyen victim, how will it affect the trial process? And in what direction will the case go?

- For cases of dead or missing people, finding victims is one of the most important factors. Once we have identified the area of ​​the victim, there will be grounds to determine the next step of investigation. Knowing the victims we know the time of death, know how the victim died and on that basis we will take further investigation steps more accurately.

In the Cat Tuong salon, we have identified the victims, on the basis of the remaining bones of the victim, the investigators will have plans to proceed to the next step. Identifying the victims area also helps investigating agencies to identify many other issues related to the victim, for example, will identify the crime that the culprit caused, identify the testimony of the culprit . The previous testimony, but not yet identified the victims, has not verified whether the testimony is correct or not for both the perpetrators and those who know the circumstances related to the incident.

Thank you very much!
