Things that solve crimes

"There's news, there's news." A young police officer pushed the door open and said loudly.

Instantly, everyone's eyes were focused on him. A middle-aged policeman nearby slapped the young policeman on the head and said, "Stop keeping us in suspense. Tell us now."

Qin Henian was silent. These two were definitely master and disciple.

The young police officer covered his head and pouted, "We found the relatives of the victim of the rape and murder case five years ago."

"The victim and his mother depend on each other for survival, and the rest of his relatives are either absent or unfamiliar to him."

"We checked the victim's mother, but we can basically rule her out as a suspect. The victim's mother was in a car accident three years ago and her legs are disabled and she can't walk."

"Are you sure the victim's mother is unable to walk?" asked an old policeman.

Anything can happen in a case, so there are some things you need to ask.

The young police officer nodded, "Confirmed. We found a doctor and confirmed that the victim's mother cannot walk."

"Could it be that Zhou Ju stole something he shouldn't have stolen?" said another veteran policeman.

The victim's mother could not have committed the crime, so the possibility of a revenge killing can basically be ruled out.

Considering that Zhou Ju was a habitual thief, it was very likely that he had stolen something and was silenced.

A fat policeman retorted, "Since Zhou Ju was taken to the police station for murder five years ago, he has never stolen anything again. There is no record of him stealing in the past five years."

The police carry out the “100-day anti-theft” campaign every year, and habitual thieves like Zhou Ju are the main targets of attention, but Zhou Ju is never seen every year.

It's impossible that Zhou Ju is just lucky and always gets away with it. Apart from this tiny possibility, it is very likely that Zhou Ju has retired.

"It can't be a murder of passion," said a thin policeman.

There are only a few motives for murder: for love, for profit, for hatred. If we rule out the last two, the only one left is the first.

The fat policeman retorted, "How can a person who goes out to prostitute himself have any love?"

"What girl would be blind to fall for him?"

The other people looked at the fat policeman with unfriendly eyes. If you want to refute, you only know how to refute. Why don’t you tell me a possibility?

The fat policeman glared back unwillingly and said, "What? You can’t just say you’re wrong."

He is not afraid, he will glare at one if one comes, or at two if two come, he will glare at both, anyway, he has big eyes~

Ignoring the "flirting" of the others, Qin Henian looked at Wang Hong and asked, "Can you show me the information about the rape and murder case five years ago?"

"Wait."

Wang Hong turned and left the meeting room. A moment later, he came back with a pile of documents. He handed the documents to Qin Henian and said, "That's all."

Qin Henian took the information, found an empty seat and sat down, then opened the file...

In the rape and murder case five years ago, the victim was named Wang Li and died between 12 and 12: in the evening.

The cause of death was a punctured heart, but multiple scars and bruises were found on the body of the deceased, indicating that he had been violated and his ring finger was missing.

The place of death was at home, and the body was found in the suburbs. The murderer must have dumped the body in the suburbs...

He tapped a line of black words with his finger, "It says here that the heart was punctured and the left atrium was damaged."

"The murder weapon is not on the body, so when the murder weapon is pulled out, blood will spray out, and there is a high probability that it will splash onto the murderer."

The blood vessel connected to the left ventricle is the aorta, whose function is to receive oxygenated blood from the left atrium and then pump the blood into the aorta to various parts of the body.

If the left ventricle is punctured, a large amount of blood will be lost in a short period of time, leading to cardiac arrest.

Wang Hong's eyes lit up, and he heard Qin Henian continue, "If we can find the clothes stained with the deceased's blood, we should be able to find the murderer as well."

"But there is a prerequisite, the murderer has not destroyed the bloody clothes, and we can find it."

Wang Hong slapped his head in annoyance. They were all paying attention to Zhou Ju back then and forgot this point.
