Chapter 78 Cause of Death
The atmosphere in the office suddenly became a little solid.
Xu Yiqing's smile was still on her face, but when she saw Zhou Shi tilting her head, with an innocent and confused look, her smile became a little stiff.
"It's...the fruit in my refrigerator at home." After Xu Yiqing's smile melted, she showed some confusion and shock: "Didn't you put it there?"
Zhou Shi shook her head: "I have never been to your home... I know you live in the forensic department, why should I go to your home?"
Although there is a refrigerator, what Zhou Shi would do is deliver it directly to Xu Yiqing's mouth, instead of keeping it in the refrigerator until it goes bad.
Looking at Xu Yiqing's shocked face, Zhou Shi also realized that there was a misunderstanding, so she looked seriously: "Do you have a lot of things at home?"
"There are a lot of fruits I like to eat in the refrigerator."
"Have you eaten?"
"I ate what I ate last night. I should be fine now."
"From now on, you can only eat canned food that you bought yourself, do you hear me?" Zhou Shi opened the door and walked out: "After you do the autopsy, go to the hospital. You must go this time!"
"Where are you going?"
"I'm going to find Mr. Du and get everything in your refrigerator for testing!"
Zhou Shi went out and met Lin Sheng face to face. Before she could explain, she walked away in high heels. The corridor was filled with the sound of her hurried footsteps.
When Lin Sheng saw Xu Yiqing chasing him out, he looked at Zhou Shi's back and refused to chase him. He thought his wife and master were having a conflict.
"Brother Xu,... why don't you go after him first? I've seen the body, and it's very skeletal. Anyway, there's no rush now."
Xu Yiqing looked back with firm eyes: "It's very urgent, prepare for the autopsy."
He put on protective equipment, disinfected his whole body, put on a medical mask and a plastic face shield, and faced the corpse on the autopsy table with Lin Sheng in full force.
During a normal autopsy, they have to worry about whether the deceased had infectious diseases such as AIDS, and they have to be careful when dealing with blood, especially when there are wounds on their hands, and be careful not to be pricked by bone spurs.
Even if the bones are turned into bones, we cannot take it lightly. Some viruses and bacteria can exist in the soil for decades!
"Prepare to start the autopsy on corpse No. 209." Xu Yiqing said.
There is no need for an autopsy on a skeletal corpse, and it is extremely challenging for forensic doctors.
It is difficult to accurately determine the time of death of a corpse to hours if it is more than a week old. What's more, in this situation where the entire corpse has completely turned into withered bones, it is even more difficult to shorten the time of death to years.
Only a few skilled forensic scientists can be accurate to the moon.
"Based on the condition of the pelvic bone, it is determined that he is a male." Because it involves bones, Lin Sheng was not just responsible for recording this time, but also participated in the autopsy. "Based on the degree of tooth loss, the age of the deceased was judged to be between 12 and 15 years old... Because the environment in which the body was stored was slightly corroded, only so much tooth wear can be seen.”
"What about the pubic symphysis?"
"I can be more precise by two years, between 14 and 15 years old."
Xu Yiqing nodded, "When recording, I will add that the deceased may have been a junior high school student."
This is inferred based on the death of the principal of No. 4 Middle School and Song Lang. It is obvious that this series of cases are related to No. 4 Middle School, and the age of the skeleton in front of him is between 14 and 15 years old. It is difficult not to let go People speculate that the deceased may have been a student of No. 4 Middle School.
Lin Sheng continued to play with the broken bones that had been turned into parts. The corpse had been bones for too long, and the soft tissue connections between the bones had been lost, and they were all scattered, which greatly hindered the autopsy.
"Brother Xu, there is damage to the skull!"
"Fatal injury?"
"Hmm...it doesn't look like it at all."
Xu Yiqing took the deceased's head from Lin Sheng's hand. The whole head was densely covered with cracks.
So he immediately understood why Lin Sheng said they didn't even resemble each other.
If it is broken like this, people will definitely die.
But the wound that caused this phenomenon must be somewhere else. Sure enough, after continuing to examine the pile of broken bones, Xu Yiqing found that the deceased's limbs and torso had varying degrees of bone cracks and fractures.
Among them, the neck, left arm, and sternum are the most obvious.
"The neck was directly broken." Lin Sheng frowned: "How did such a... barbaric wound occur?"
He observed the fracture of the cervical vertebrae and imagined the injuries before the soft tissue decayed: "It was as if someone had directly twisted off the head of the deceased... It was still a very strong pull."
But this is reality. There is no such monster that can directly twist off a human head. Even if it is a beast, there is no way to explain the cracks on the head of the deceased.
Xu Yiqing said: "Almost all the ribs were broken, and the left arm also had exaggerated wounds like the neck. Plus the neck..."
Lin Sheng also thought, he couldn't figure out how such a brutal wound was caused.
Xu Yiqing already had the answer: "We can write down the cause of death. The deceased died from a fall from a high altitude and tended to jump off the building."
As a junior high school student, Xu Yiqing didn't think he would fall from a tower crane or the like, so the most common fall from high altitude is jumping from a building.
Lin Sheng was slightly startled when he heard this. He looked at the wound of the deceased again and suddenly realized.
Check out the 16-9 book bar and see the correct version!
"The floor he fell from must be quite high. His left hand and head were broken directly!"
In the past, the Forensic Medicine Department would also receive the deceased who jumped from the building. Jumping from the building was far from falling to pieces like ordinary people imagine. In fact, it was common for the deceased to be broken into pieces after falling.
The lower floor may have broken bones. The dead man's broken arms, legs and bones were turned out, which was very miserable.
On higher floors, it is very common for people to smash them directly.
If there was still flesh and blood on the body, Lin Sheng would definitely be able to tell at a glance that the deceased died from falling from the building, but now that the flesh and blood had rotted away, he did not immediately realize the cause of death.
Moreover, for ordinary falls, the deceased would be brought in as soon as possible, instead of starting the autopsy many years after such a fall.
Lin Sheng asked: "Why would you pull over a body that had been dead for so many years and do an autopsy? I heard from the criminal police officer who told me that it was dug out of the coffin."
Xu Yiqing shook his head and took off his gloves and protective measures: "That's not clear. At least the cause of death has been identified. In addition, let the laboratory department do radioactive isotope determination, decalcification and protein determination as soon as possible."
Nowadays, science and technology are becoming more and more advanced, and there are more reliable scientific methods than forensic experience to determine the time of death of the bones.
Soon there was a reply from the laboratory department. The time of death of the deceased was about eight years ago.
Xu Yiqing asked Lin Sheng to write the autopsy report and send it to the criminal police team, and he planned to take a taxi to the hospital for a check-up to prevent him from being poisoned.
On the other side, Du Yu and Zhou Shi were shocked beyond measure in the fruit shop where Xu Yiqing frequented.
Ten minutes ago, Zhou Shi took Du Yu and several police officers to Xu Yiqing's home, preparing to send all the food in his home for inspection.
Then the police found a plastic bag containing receipts while rummaging through the trash can.
The fruits on the receipt matched the fruits in the refrigerator. Zhou Shi could tell at a glance that the logo printed on the plastic bag was the fruit shop Xu Yiqing often went to.
So after asking the police to take the food for inspection, Zhou Shi led Du Yu to the fruit shop at the entrance of the community.
"That's right, you bought it from us." The clerk in the fruit shop nodded and was very sure: "Banana, jackfruit and cherries, each weighing about 300 grams. You can't go wrong. He is the one who comes to us often. Customers in the store.”
"Are you sure it's him?"
"I remember correctly, he is the only one who buys these three items every time he comes here. If you don't believe me, just watch the surveillance!"
There was a time on the ticket, so Du Yu and Zhou Shi quickly called up the monitoring of the corresponding time in the background.
But the people inside left them shocked and confused.
It's Xu Yiqing!
