Survey expert: there are no traces of activities at the launch of the Hu Xinyu case.

The Jiangxi Police held a press conference on Thursday (February 2) on the case of Hu Xinyu, a high school student in Liaoshan County, Shangrao City.Experts participating in the on -site exploration disclosed more details of the case, saying that the traces of the corpse found that Hu Xinyu had moved on the wall and no other people's activities were found.

The Deputy Director of the Criminal Technical Division of the Interpol Corps of the Jiangxi Provincial Public Security Department and the trace inspection of the senior engineer Cheng Jian said in an interview with CCTV News on Thursday that after the on -site surveyor arrived at the scene, he first extracted a pair of white back forceShoes and left foot shoes can be seen directly, but the right foot shoes are covered by a layer of dead leaves, and only the tip of the shoe is exposed. If you don't check it carefully, it is difficult to find this shoe.

He said that after confirming that these shoes were Hu Xinyu through DNA comparison, the technicians carefully investigated the shoes in the laboratory, and extracted the moss on the bottom of the wall on the soles of the shoe.Attachment.After inspection, these attachments were consistent with the types of moss on the wall, so Hu Xinyu was judged that Hu Xinyu had moved on the wall before his lifetime.

At the same time, the survey staff also found the traces of stepping on their feet on the wall brick on the scene, and the moss stepped on the marks of Hu Xinyu's soles of the moss, showing that Hu Xinyu stood on the brick of the wall before his lifetime.EssenceWhen the scope expanded, it was not discovered that the traces similar to the two bricks were again discovered, indicating that no one else was acting on the spot.

Cheng Jian also introduced that according to the on -site exploration confirmation, Hu Xinyu's body was two shoelaces tied together, from the pair of white sports shoes found on the spot.

In response to the question of whether the shoelace of Hu Xinyu can be suspended from the outside world, the question of whether the body weight can be carried for a long time.The lace is composed of polyester fiber. Unlike cotton shoelaces, polyester fiber shoelaces have doubled weight than cotton shoelaces.Experts also conducted experiments and found that polyester fiber laces can be loaded to 85 kg.According to police investigations, Hu Xinyu was 60 to 65 kg during his lifetime, within the bearing range of the lace.

For the reasons why the shoelaces are not broken, Zhu Chengren, director of the Criminal Technical Division of the Interpol Corps of the Interpol Corps of the Interpol Corps of the Public Security Corps of the Jiangxi Provincial Public Security Department analyzed that the first reason is that this material makes the shoelaces not easy to corrupt.The second reason is that the body's weight will become lighter and worse, and it will not be heavier, so the rope has not broken yet.

Zhu Chengren also mentioned that after the police inspected the corpse, it was found that there was a cable formation formed by the corpse and neck. There were obvious marks of bleeding on the edge of the cable ditch, indicating that the traces were formed when the flesh was alive.It can exclude the suspension after death.In addition, the body can basically rule out poisoning death through poison testing.Based on the above -mentioned factors, Hu Xinyu's death was to die.
