Attending ex-girlfriend's wedding, arresting the groom's officer on the spot

"The puncture wounds were not neat and there were a certain degree of burr scars. The reason for these scars is because the murder weapon used by the murderer was not sharp."

"But the murderer still killed four people with wounds that were not actually sharp. Especially when the murderer killed two female victims, one had an abdominal wound and the other had a chest wound."

"This requires a lot of strength. I roughly calculated that it may require a force of at least 100 kilograms to cause such an injury."

"There are very few people in the female community who are as powerful as this."

"So, the owner of the footprints is most likely to be male."

"Whether the other party wore high heels for disguise, or whether the other party wore high heels for some other special reason, the current investigation cannot make any inferences."

"But...I personally prefer killing for love!"

Love kill? !
Man, love killing? !
"what do you mean?"

"We know that the deceased Zhang Xiaotian had a history of living together with Wang Junshan. I heard at noon that during the investigation, some neighbors reported that Zhang Xiaotian is gay. Since the murderer is a male and wears high heels, can we infer that there is also a relationship between the other person and Zhang Xiaotian? Some kind of relationship.”

"Of course, this is just a guess. The specific situation needs to be further verified. On the other hand, there is a major question."

"When the action team visited and investigated, the seven tenants living in the building said they did not hear any sounds. I think there is something suspicious here."

Liu Guodong nodded: "We discussed this point during the experiment."

"The soundproofing of the room at the crime scene was very poor. When we were investigating the scene, the action team was visiting and investigating next door. We could vaguely hear the conversations between the neighbors and them."

"Judging from the situation at the scene, there was a struggle between the two female victims and the murderer when they were killed."

"Since there was a fight, didn't any sound get out?"

"Is it possible that the other party faked the scene and there was no actual struggle?"

"impossible!"

"There is no trace of fraud in the blood spray at the scene. No matter from the angle and intensity of the spray, or the obstruction of the spray trajectory, there is no possibility of fraud. There were only three people fighting at the scene."

This point has been repeatedly confirmed by the current survey, and Lu Chuan spent a lot of thought on it.

"So, we suspect that the tenant may not be telling the truth!"

Liu Guodong and Lu Chuan's judgment silenced everyone.

"I agree with the current survey's judgment."

After a while, Zhang Hui was the first to speak up: "Everyone has been to the scene. The soundproofing in the rental building is indeed very poor. Although three to four o'clock in the morning is the worst time for people to sleep, there shouldn't be no sound at all."

"Besides, some of these tenants were selling vegetables at the vegetable market and got up very early. They also said they didn't hear any strange noises. This is not very logical."

"One more thing, when we asked Wang Junshan, we learned from him that the reason why Wang Junshan moved out of the building was because Zhang Xiaotian asked him to join a mutual aid group in March of the beginning of the year."

Mutual aid?
"What mutual aid group?"

"Wang Junshan doesn't know much about the mutual aid association. He only knows that it is an organization in a rental building."

"I wonder if we can start investigating from this point?"

Zhang Hui's words attracted everyone's attention.

Although Zhang Hui didn't say it clearly, the meaning behind his words...

"Collusion?"

The question raised by someone unknown caused the conference room to fall into silence.

Conspiracy in murder case!

Not none, but very few.

The criminal investigation detachment has cracked many cases over the years, and it is not uncommon to see collusion in murder cases.A few years ago, there was an extremely special case of collusion in a murder case, which was publicized and studied throughout the system.

An underage female student accidentally killed a male classmate who was teasing her. In order to save his child from jail, the girl's father teamed up with everyone in the family to confess.

By forging travel records and secretly changing the concept of time, the other party indirectly allowed many people who came into contact with them to provide alibi for them, and they did escape suspicion at first.

Later, the story was even made into a movie.

There are some murder cases, such as a son killing someone and the father helping to hide the collusion, which is normal.

However, judging from previous cases, murder conspiracy usually occurs between blood relatives.

Tenants of rental houses in a building collude with each other, and there are actually 7 households involving more than [-] people... I have never seen this situation before.

"Are there any other clues from Wang Junshan?"

"not yet."

Qin Yong patted the table: "Let me tell you about the work below."

"The current investigation team must confirm the identification and analysis results of the DNA information as soon as possible, and the action team will cooperate to speed up the collection of blood samples from all residents in the rental house."

This can be regarded as a routine operation. A thorough search of the people near the crime scene and comparison with the DNA information of the murderer found at the crime scene may lead to clues.

If the comparison is successful, the case is solved.

Because from a probability perspective, killing is limited by time and space.

Rarely would a person appear, cross thousands of miles, suddenly go from one place to another, kill people, and then return directly.

Whether it is a murder for love or a murder for money, there must be some kind of time and space relationship between the murderer and the victim.

This is also an important reason why many murders are committed by husbands, wives, neighbors and relatives.

"In addition, the action team should focus on investigating and arranging the mutual aid club that Zhang Hui just mentioned."

"Carry out a detailed investigation of all tenants in the building, but pay attention to methods and take necessary confidentiality measures."

"Yes!"

After the case analysis meeting, Liu Guodong and Lu Chuan returned directly to the current investigation laboratory.

Yang Sen and Lao Bai were wearing white coats and still working in the laboratory.

"How about it?"

"We're almost done here. The preparations are complete. We're just waiting for the action team to send the blood samples. It will almost be done in one day."

"I think the murderer is hidden among these people. As long as we compare him, he will be exposed."

"Okay, it's been a hard day today. Let's go back to the office and take a nap first. We'll fight again tomorrow!"

The forensic department is quite busy. There are still two corpses that have not been dissected. Wang Changjiang and Shen Yan will have to work overtime tonight.

The action team is busier here.

If a question arises during the on-site visit and investigation, it is not possible to do it again directly. In that case, the result will still be the same as the first time.

Zhang Hui's opinion is to first check the assets of these people, especially the landlords.

If you have some useful information in hand, and then investigate, your right to speak will be different.

Everything is going on in full swing. (End of chapter)
