Cai Liao, who looked at the body, did not blink his eyes and said: "The deceased was a male, and the time of death was between four and six hours."
Qin Jun: "But the stiffness of this corpse is obviously more than four to six hours?" There are more cases, and they are somewhat familiar with some common post-mortem symptoms.
Cai Liao did not raise his head, and reached out to the waist of the cut corpse, saying: "You have ignored the influence of the external environment on the stiffness and time of the corpse.
The body was found on the bank of the river. The temperature of the body bag was lower than that of air. The body bag was full of water. There was also a seven or eight kilogram stone in the body bag. It was obviously used to increase weight and sink it. The old man who reported the crime found the bag on the shore. "
Qin Jun: "So someone sank it to the bottom and then fished it up again?"
Cai Liao: "That's right, the temperature in the depths of the river is about eight to ten degrees lower than that on the shore, and the corpse is divided, which further accelerates the speed of the corpse.
A piece of 20 kilograms of pork with body temperature and a piece of five kilograms of pork are rapidly cooled at the same time. Who do you think will be chilled first? "
When Qin Jun heard this, he couldn't help his brain filling the human flesh to cool the picture, his stomach rushed, and his mouth slumped, waiting for Cai Liao to continue speaking.
Zhu Yu: "Is it possible to put refrigeration equipment and then throw them to the shore?"
Gu Minsheng, who had not spoken all the time, opened his mouth: "Freezers and refrigerators are not impossible, but the possibility is too low. There are only a few households in Yan County. If the murderer uses the freezer, then our scope of investigation will be greatly reduced. Now. If this was a murder, the murderer would definitely not use such obvious methods."
Cai Liao focused his attention on the incision of the corpse and said: "If it is a freezing device, the overall temperature of the corpse will not be so balanced. The rapid cooling and natural cooling in the ultra-low temperature state, both in terms of the texture and condition of the fleshy road. difference."
Zhu Yu nodded, as expected, something like an autopsy had to be done by a forensic doctor.
Cai Liao stared at the corpse, and then said: "From the physical state, muscle texture, etc., the age is about 30 to 40 years old. The thigh injury was caused at least half a year ago.
The skin of the scar is scarlet and bloodshot, and the subcutaneous muscles are obviously severely damaged and deformed. These symptoms are caused by severe burns, which means that this person had an accident six months ago.
The scabs and pus on the knee were caused by infection of the wound. Inferred from the leg length and arm length at the scene, the height of the deceased should be between 1.78 to 1.82 meters.
The incision was lighter in color, and a small amount of blood remained. He was bled before death, or the bleeding caused his death. The cut of the corpse piece is serrated, and the tool used to divide the corpse should be serrated, but the common sawtooth marks are not so deep. At the same time, from the appearance of the cut surface, it is cut off at various positions in one go.
Zhu Yu and Qin Jun couldn't help but get goose bumps when Cai Liao talked about them.
Cai Liao took the deceased's hand and looked at it carefully, and took some powder from his nails and put it on the tip of his nose for a while, before saying: "The residues in the deceased's nails are yellow mud powder and gunpowder powder."
Zhu Yu: "I am engaged in work related to fireworks and firecrackers."
Cai Liao nodded, "Fireworks and firecrackers have the greatest possibility, and this also makes the deceased's leg burned, which is more reasonable."
After Zhang Chengshan received the call, he just heard what Cai said and nodded, "Yes, it is true that fireworks and firecrackers are the most likely to be exposed to these two things at the same time. In recent years, small workshops have also had accidents. Quite a lot."
