I'm not a super cop

Chapter 377 Five Kinds of Trauma
After returning to the team, colleagues from the forensic department began to dissect the corpse, and colleagues from the technical team also analyzed the items found at the scene.

Xiao Ran first reported to the team leader, and then began to inquire and collect information on missing persons in various jurisdictions around the past half month.To find out the truth of the death, we must first determine the identity of the deceased.

However, it will not be easy to start this work for a while, and it is now in the middle of the night, and there is no condition to go out to visit and investigate.

In the small conference room, Xiao Ran recalled the off-road outfits carried by the deceased, and suddenly asked, "Recently, have there been organized off-road hiking activities or competitions around our city?"

"This... I haven't noticed it, but I checked it online. If there is a competition or something, there should be reports, right?" Liu Qing took out his mobile phone and started searching.

"If you can't find it, wait until dawn, and then we'll look for people who are more famous in the off-road area around. There must be circles for those who play off-road. It may be relatively easy to find in the circle." Xiao Ran looked out of the window The black night sky seemed to be talking to itself.

Liu Qing nodded, staring firmly at the screen of his mobile phone, and suddenly he patted the table, "Hey, there is one! Ten days ago, on May 5th, a cross-country competition was held in a certain district of our city. There are more than 12 participants, the race is 3 kilometers, and the finish line is in a county in the west of the city, and Wanggong Mountain is just near the cross-country route!"

"Let me see!" Xiao Ran took the phone and carefully read the news that few people read twice.

The current weather, ten days, is enough to make the corpse decay to the present stage.

"The deceased is likely to be a participant. Contact the event organizer and ask for the registration information of all the participants at that time."

Xiao Ran returned the phone to Liu Qing, but looking at the time again, he said helplessly, "...try to get in touch, if you can't get in touch, then wait until tomorrow."

In the dead of night, there was no sound in the office building.

Time passed by little by little, and it was already midnight.

During this period, although sporadic information came together, they were of little value, and the phone of the organizer of the event that was found was always turned off.

Fortunately, Yu Yu has made new progress. The autopsy has been completed. Xiao Ran brought Liu Qing and others to the office area of ​​the Forensic Medicine Department to learn more about the autopsy.

Yu Yu, who came out after changing clothes, threw the notebook in his hand on the table, pulled a chair and sat down straight away, and the first sentence he spoke made everyone's hearts ache: "There is indeed a possibility of homicide!"

The office area was silent for a few seconds, and the atmosphere of silence was a bit weird. Xiao Ran knocked on the table, looked at Yu Yu and said, "Keep talking, what do you stop for?"

"Let's brighten up the atmosphere."

Yu Yu spread his hands, opened his notebook, looked at the messy records on it, and organized his words, "Through anthropological examination, the deceased was male, around 50 years old, 180 cm tall, and in terms of body shape, due to the high degree of corruption of the corpse It's easy to estimate, but according to the label of the deceased's clothes, it can be inferred that the figure of the deceased is fairly standard, neither fat nor thin."

"Here I would like to add that the deceased's financial conditions are good, he is a professional cross-country player, and he probably participated in a cross-country competition held in a certain district of our city ten days ago." Xiao Ran shared the condition of the deceased's equipment with everyone. After saying it again, everyone who listened was stunned.

Zhang Lei exclaimed in surprise: "I'll go, Xiao Ran, since when did you become so familiar with off-roading? ——I didn't expect that there are so many know-hows in this person's things!"

"What did you just say? Ten days ago?" Yu Yu brought the topic back and asked with a slight frown.

Xiao Ran nodded, "On May 5th, a cross-country race was held in a certain district of our city. Does it match the time of the deceased's death?"

"It's not certain yet. After all, the deceased's body is highly corrupted, and there is no change in the body that can infer the time. I plan to cultivate fly larvae in the future, and use forensic entomology to calculate the death time of the deceased."

Yu Yu shook his head, and said again: "By the way, the DNA of the deceased is already being done. The follow-up comparison may take some time, so be prepared."

After Yu Yu finished speaking, Zhang Lei also said, "I would like to add here that fingerprints were extracted from the deceased's cane, but no DNA was extracted. As for whether the fingerprints belonged to the deceased, it is hard to say yet.

In addition, the dead man's headlight had sufficient power, and it seemed that it had not been used after it was fully charged.

The nail stuck on the shoe of the deceased was an ordinary iron nail. After analysis, we judged that the nail should have been stepped on by the deceased unintentionally. "

Xiao Ran listened carefully, "Continue to talk about the results of the autopsy."

Yu Yu nodded, and his expression became serious: "After the autopsy, we found that there were five obvious injuries on the deceased's body: one was a comminuted skull fracture, the other was a skull fracture in a special state, and the third was a linear fracture of the phalanx. , the fourth is the skin contusion on the lower back, and the fifth is the wound on the sole of the right foot."

"The injury on the sole of his right foot should be caused by the iron nail on the sole of the shoe. Everyone knows that."

Xiao Ran frowned and said, "But you said that the deceased had two types of skull fractures, and his phalanx was also fractured. Tell us about these two points in detail."

"Ok."

Yu Yu thought for a while and said: "After the anatomy and craniotomy, we determined that the deceased's skull was fractured, and it was a comminuted fracture. So we tried to restore the fragments of the deceased's skull, and found that the deceased's skull had three injuries. "

"The shape of the two skull fractures is very irregular. The analysis is that the skull is in contact with a blunt object, or formed after a fall."

Yu Yu casually flipped to a blank page in the notebook, took a pencil and carefully drew the shape of the skull fracture of the deceased, and then said: "The other shape is this kind of narrow fracture, with relatively neat edges and a length of about 3 centimeters. There is still a certain width, it feels... It feels like a dagger is pierced into it.

As for the linear fracture of the phalanx, if you simply fall, as long as the forearm and metacarpal remain intact, phalanx fractures rarely occur.And we are sure that the injury to the phalanx was caused by a blow, but it is difficult to judge the tool used to cause the injury. "

"The injury on the hand is okay, but if you stab the skull with a dagger, with the hardness of the human skull, I'm afraid you have to be a martial arts master to stab it in!" Zhang Lei said puzzled.

"That's how I describe it, and I didn't say it was a dagger."

Yu Yu glared at Zhang Lei: "Although I don't know what weapon caused this special skull fracture, I can be sure that four conditions must be met in order to form such a fracture.

First, the injuring tool must be hard and heavy, second, it must have a flat and narrow contact surface, and finally, it must be easy to swing. In addition, the suspect must have sufficient strength. "

"Then what do you think it is? It has a long enough handle, and a dagger is fixed vertically on the handle..." Zhang Lei gestured with his hands in the air, and suddenly his eyes lit up, "Hey, is it a sickle? It looks like Why!"

"It's not!"

Yu Yu firmly vetoed Zhang Lei's conjecture, "Agricultural sickles are not good enough, unless they are special iron handle sickles with specially treated blades."

There was a lot of talk in the office area, everyone was discussing this special crime tool, but the discussion did not come to a result.

Bang bang bang!
Xiao Ran, who had been in deep thought, suddenly knocked on the table, he slowly raised his head and said, "I know what this is!"
