Regarding the age of the deceased, Ouyang Ping and Liu Dayu also wanted to ask Guo Changping to confirm it again. Guo Changping, everyone should remember! He is a well-known criminal investigation expert in China, and his greatest achievement is to compile several very weighty criminal investigation monographs based on years of criminal investigation practice. Ouyang Ping and Liu Dayu set the age of the deceased between thirty-four and forty years old, which is indeed a bit older. This is because the two people have encountered something uncertain.

In addition to the shirt and pants on the deceased's body, there are two other things: a pair of boxer trousers, a copper-toed cowhide trouser belt, the material of the trousers is the same as the trousers, it is also cotton, the trousers and trousers are attached to the well-defined bones, the degradation of the soft tissues on the deceased's body has reached the final stage, and only bones are left in the trousers and trousers; The width of the skin is 2.5 centimeters, and there is a relatively obvious patina on the copper head, and the head of a lion can be seen by scraping off the patina.

Ouyang Ping and Liu Dayu only extracted a good shirt, a belt, a pair of nylon socks, a pair of leather shoes, a lighter, and a wallet from the deceased. The most valuable thing is ten hairs of about the same length. As for the trousers and trousers, they were only saved on the photos: Ouyang Ping and Liu Dayu moved the corpse every time, so they asked Zuo Xiangdong to take a few photos, Ouyang Ping and Liu Dayu also wanted to extract a little fragment of the trousers and trousers, but they failed to do so, unfortunately, every time they moved the corpse, the trousers were torn apart, and when Ouyang Ping touched the trousers and trousers with tweezers, he found that they had rotted into mud and silt.

At 9:45, the on-site investigation and autopsy ended, Ouyang Ping, Liu Dayu and Chen Jie washed off the mud on the corpse with tap water and put the corpse into a special box with formalin liquid.

At half past one o'clock in the afternoon, Guo Lao was invited into the forensic medical department, and Ouyang Ping, Liu Dayu and Chen Jie were waiting for Guo Lao in the forensic medical department.

Guo Lao took the mask and gloves from Liu Dayu's hands, and then put on a white coat.

On the operating table, there is a stainless steel utensil 1.8 meters long, 70 centimeters wide, and 50 centimeters high, in which lies a corpse, soaked in formalin liquid. Although the corpse still had some peculiar smell, it was not very noticeable.

A universal wheel is mounted under each of the four legs of the operating table.

A meter above the corpse, a spotlight hangs.

Guo Lao stood in front of the operating table, Ouyang Ping stood next to Guo Lao to give him a hand, and the others stood on both sides of the operating table. All eyes were focused on Guo Lao's hand.

Guo Lao first carefully looked at each of the deceased's teeth, and then carefully looked at the deceased's skull, especially the occipital bone and hairline.

Twenty minutes later, Guo Lao took off his mask and leather gloves.

"Old Guo, how is it?"

"The age of the deceased is about thirty-six years old, and your judgment is correct, and the scope of the criminal investigation can be set between thirty-four and thirty-eight years old -- this will be more secure."

"Old Guo, please tell us in detail." Ouyang Ping has always been open-minded and studious, he will not miss any opportunity to learn, the opportunity is rare, not only to know what it is, but also to know why it is true.

"The deceased's teeth were full and the tooth quality was very good, although it had been soaked in the mud for a long time, it could still be seen that as for this missing tooth, it did not fall out naturally, you see, clean the mud at the root, it is not difficult to find that this is a broken tooth." Guo Lao said as he pinched a cotton ball with tweezers and rubbed it a few times on the root, Ouyang Ping finally saw clearly, and at the root, there was indeed a small piece of broken teeth that fell on the gum.

Guo Lao pointed to the hairline with tweezers - there was only a small hairline on the deceased's head, and most of the scalp had been separated from the skull: "The deceased's hairline is relatively forward, and there is no backward movement, and the hair here is still relatively dense and the hair quality is also very good, which is also an important basis for judging age." ”

The soft tissues on the deceased's body are highly decomposed, and the degree of degradation is relatively high, but it is not completely fully degraded, and some soft tissues are still attached to the bones.

Regarding the time of death of the deceased, Guo Lao agreed with Ouyang Ping and Liu Dayu's judgment, but he preferred early autumn, the reason is: the underground environment is relatively special, the temperature is much lower than normal, and the body decomposes more slowly.

At about half past two, Ouyang Ping and his entourage returned to Xie Juren Lane, and the comrades, with the assistance of Director Qi and Director Wang, divided into several ways to carry out an investigation.

On the first road, Ouyang Ping, Li Wenhua and Han Lingling asked Director Wang to learn about the household registration of the relocated households, and in the eyes of the comrades, "95. 8。 3 "The homicide is very likely to be related to this demolition, and the deceased and the murderer may be among these demolition households, or at least related to these demolition households. After the demolition plan was finalized, the families who originally lived in the "Xie Xi's former residence" must all move out. This way, Director Wang and Rao Ping, the housing manager of the district housing management office, led the way.

In the whole demolition work, in line with the principle of ensuring smooth demolition and cost savings, the demolition households were studied several times, and the final list was only 17, and there were more than 20 households near the Chen family compound alone. In particular, the residents in the other three courtyards of Shigu Lane should also be the focus of the investigation. This route was led by Tang Xiaozhang, a police officer from Xie Juren Lane.

Director Wang and Director Qi said that as soon as the demolition plan was introduced, the nine families living in the "Xie Xi's former residence" were relocated in half a month, and the Municipal Bureau of Cultural Relics completed the repair of the former residence in only half a month. This route was led by Director Qi.

Let's take a look at Ouyang Ping's situation along the way:

When Ouyang Ping, Li Wenhua, and Han Lingling arrived at the police station, and walked into Director Wang's office, there were three people sitting inside, one was Director Wang, and the other two were Rao Ping, the housing manager of the district housing management office.

At that time, China's real estate industry had just started, and urban construction had just been put on the agenda, and monetized demolition was a later matter, and a large number of old houses in the city were all under the control of the state.

The heads of the four households in the Chen family compound are: Zhao Yaru, Gan Dejun, Zhang Bingkun and Men Xuecai.
