"The puncture wounds are not neat, and there are a certain degree of burr scars. The reason for these scars is that the murder weapon used by the murderer is not sharp."
"But the murderer still uses this kind of weapon that is not actually sharp. The injuries killed four people, especially when the murderer killed two female victims, one was injured in the abdomen and the other was injured in the chest.”
“This requires a lot of strength. I made a rough calculation. It may take a force of at least 100 kilograms to cause this kind of injury."
"There are very few people who can reach this level of strength."
"So, The owner of the footprints is most likely to be male.”
"Whether the other party is wearing high heels for disguise, or whether the other party is wearing high heels for some other special reason, this current investigation cannot make an inference."
"But...I personally prefer to kill for love!"
Love murder? !
Man, kill for love? !
“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, and the specific situation needs to be further verified. On the other hand, there is a major question."
"The action team is there. During the visit and investigation, the seven tenants living in the building said they did not hear any sounds. I think there is something suspicious here."
Liu Guodong nodded: "This is what we were doing when we were doing experiments. "We discussed it."
"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. Clear.”
"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 struggle, didn't any sound get out?"
< br>"Is it possible that the other party faked the scene and there was no actual struggle?"
"Impossible!"
"There are no traces of fraud in the blood spray at the scene, regardless of the angle and intensity of the spray. , or judging from the obstruction of the jet 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 have told the truth!”
The judgments of Liu Guodong and Lu Chuan silenced everyone.
“I agree with the judgment of the current survey.”
After a while, Zhang Hui was the first to speak up: “Everyone has been to the scene. The sound insulation in the rental building is indeed very poor. At three o’clock in the morning Although it is the deadliest time for people to sleep at four o'clock, there shouldn't be any sound at all. ”
"Besides, some of these tenants were selling vegetables in 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, we are asking Wang Junshan At that time, I 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 group?
"What kind of mutual aid association?"
"Wang Junshan doesn't know much about the mutual aid association. He only knows that it should be 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?"
I don't know who raised the question, which made the conference room Silence fell.
Conspiracy in murder case!
Not none, but very few.
The Criminal Investigation Detachment has cracked many cases over the years, and collusion in murder cases is not unheard of. A few years ago, there was an extremely special case of collusion in a murder case, which was publicized and studied throughout the system.
A minor female student accidentally killed her male classmate who was teasing her. In order to save his child from jail, the girl’s father united 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, for example, the son killed someone, and the father helped hide the collusion, which is normal.
However, judging from previous cases, murder collusion usually occurs between blood relatives.
The tenants of the rental houses in a building collude with each other, and there are actually 7 households involving more than 20 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 talk about the work below."
< br>"The current investigation team needs to 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 is also a routine operation, and we will collect blood samples from all residents near the crime scene. The personnel conducted a thorough investigation and compared the DNA information of the murderer found at the crime scene, and they might be able to find clues.
If the comparison is successful, the case is solved.
Because from a probability perspective, killing is limited by time and space.
Rarely does a person appear, crossing thousands of miles, suddenly from one place to another, and then kills the person and returns 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 the mutual aid club mentioned by Zhang Hui just now."
"Carry out a detailed investigation of all tenants in the building, but pay attention to methods and take necessary measures Confidentiality measures.”
“Yes!”
After the case analysis meeting, Liu Guodong and Lu Chuan returned directly to the investigation laboratory.
Yang Sen and Lao Bai were wearing white coats and still working in the laboratory.
"How's it going?"
"We're almost done here. The preparations are all done. 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 it, the secret will definitely be exposed."
"Okay, it's been a hard day today, go back to the office and get some sleep first, and 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.
When questions arise 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 advice 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)
