At the same time, the police officers of the other investigation teams had also temporarily completed the preliminary trace inspection work.
"Captain Yan, we didn't find any complete fingerprints or footprints in the bathroom or the suite. The door lock in the suite didn't show any signs of being pried open, and all the windows were equipped with anti-theft nets. The suspect couldn't have entered through the window.”
Jiang Yi had mentioned all of this before, so Yan Jun simply nodded and asked,""Is there anything missing in the house?”
"No, I haven't."
The police officer from the investigation team shook his head and said,"There were no signs of the crime scene being turned over, and no valuables were found missing.”
Yan Jun thought for a moment, then said to the police officer in front of him,"Did you find the victim's phone in the suite?”
"Not really."
The police officer shook his head as well." We checked every corner of the deceased's suite. We didn't find any valuable clues like a cell phone. However, there was a computer in the deceased's bedroom. Our comrades in the technical team are checking the contents of the computer.”
"After the murderer killed the victim, he didn't forget to take the victim's phone away.”
Yan Jun narrowed his eyes and said," This murderer is quite meticulous and has a strong psychological quality. He didn't leave any mistakes at the scene."”
"That's right. This murderer has a certain degree of anti-reconnaissance ability. He's very likely a repeat offender.”
Jiang Yi nodded.
On the other side, Su Yan had completed the preliminary autopsy work. She took off her mask and gloves as she got up and left the bathroom. She was surprised to see Yan Jun talking to Jiang Yi.
She had been working in the West City Branch for a long time, but this was the first time she saw Yan Jun talking so seriously to an intern police officer.
"What are the autopsy results?"
Yan Jun asked Su Yan.
"According to the condition of the corpse, we can determine that the time of death of the deceased was twelve hours ago, which is around 9:30 last night.”
"Judging from the degree of blood splattering on the wall of the bathroom, the bathroom is the first crime scene," Su Yan said.
The hymen of the deceased was torn. She was not raped before she died, but there were many cuts on her body. From the cut surface of the wound, it was mostly a knife and axe. The fatal wound was on the head. However, the shape of the wound was very unique. For the time being, it was impossible to determine the exact crime tool.”
"Unable to determine the exact crime tool?”
"What kind of fatal wound is it?" Jiang Yi asked with narrowed eyes.”
Although Jiang Yi had also briefly observed the condition of the wound on the corpse, Su Yan still had to describe the specific situation.
Su Yan glanced at Jiang Yi and hesitated for a moment before saying,""It's a huge hole with a penetrating fracture. It should be caused by a blunt force.”
Although it was just a simple reply, the police officers who were investigating looked at Jiang Yi in surprise.
" Did you see that? Forensic Su Yan actually answered the intern police officer's question. It's really rare…"
"Forensic Su Yan is usually so cold and aloof. Other than responding to Captain Yan and the leader, this is the first time I've seen her respond to an intern.”
"Yeah, she usually doesn't respond to our questions. What's going on today?”
……
Su Yan took out her phone from her pocket and took out the photo of the corpse's wound." This is a photo of the wound. As for the exact weapon, you can analyze it yourself. I'm only responsible for the autopsy.”
Yan Jun stared at the photo for a long time. He frowned and said,"It looks like a wound caused by a hammer, but it's different from an ordinary hammer wound. I'll show the photo to my colleagues in the team later. We'll be able to determine the exact weapon if we spend more time.”
Jiang Yi stared at the photo on Su Yan's phone for a while. Just as Su Yan had described, the wound was indeed a huge hole. The marks on the edge of the wound were regular and clear.
This kind of wound was not common, but Jiang Yi had a lot of experience in solving cases in his previous life. He had come across all kinds of strange wounds, so he quickly came to a conclusion.
"If I'm not wrong, the weapon should be a special explosion-proof octagonal hammer.”
Jiang Yi said.
"Explosion-proof octagonal hammer?"
Yan Jun immediately took out his phone, opened the search engine, and started searching for pictures of the explosion-proof octagonal hammer. After comparing it with the pictures of the wound, he looked at Jiang Yi with even more shock.
Although he had already noticed that this young man was extraordinary, Jiang Yi's performance had far exceeded his expectations.
"This kind of explosion-proof octagonal hammer is different from ordinary hammers. It is usually used in explosion-proof places. It can only be used in chemical plants such as the oil, natural gas, paint, and fertilizer industries. This means that the murderer is likely to be a factory worker or has worked in these factories before.”
" Besides, operating this kind of explosion-proof octagonal hammer is very laborious," Jiang Yi analyzed." The murderer was able to use this kind of octagonal hammer to pierce through the victim's head. This means that his arm strength is very amazing.”
"Well said. Continue your analysis.”
Yan Jun's expression was actually a little excited. He fought hard.
"Previously, Dr. Su said that the victim was not raped before death, but when I examined the victim's body, I found that there were many bruises on the victim's body, and they were concentrated on the inner thighs, chest, and other parts. This means that after the murderer killed the victim, he used his hands or other parts to rape the victim's body.”
"From this, it can be inferred that the murderer is a male. He may be alive." There is a flaw in the theory, so it is impossible to carry out the corresponding sexual offense. We can only use other methods to carry out obscene acts. I think that we should conduct a detailed examination of the deceased's mouth.”
"I'm going to bring the body back for further examination to see if there's anyone else's DNA in the mouth.”
Su Yan said.
"There are no fingerprints or footprints left at the crime scene, which means that the murderer has a certain anti-reconnaissance ability and may have a criminal record. According to this analysis, we can infer that the murderer is an adult male with a strong physique. He currently works in various chemical factories or has worked in various chemical factories before. He had the key to the deceased's house.”
Jiang Yi said.
"This way, Hong Qiuxia's suspicion is eliminated.”
Yan Jun pondered and said,"Could it be Hong Qiuxia's husband or other male relatives and friends?”
"I won't."
"The murderer is a furniture installation worker." Jiang Yi shook his head.”
