"Actually, judging from Jiangyuan's and Shannan's suggestions, I feel like we can already try to do some troubleshooting."
Political Commissar Liu spoke in the middle of the meeting, stopping the lively discussion.
Anyone with a discerning eye can see that the information Jiang Yuan sent over is indeed enough to meet the basic conditions for eliminating the ancients.
Jiang Yuan only came for a day and started a large-scale investigation. "We have to draw a range." The detachment leader lowered his head and peeled an ugly orange.
The ugly oranges were sent over by Director Xu, who is in charge of criminal investigation. Director Xu did not come to attend the meeting, but in the past few days, the director has asked people to send fruits, and the value is getting higher and higher, which makes people bitter.
The several captains nearby all received the oranges given to them by the detachment captain.
The oranges are sweet and juicy, making people's tolerance continue to increase.
Indeed, compared with a little bit of face, the director is really scary.
"I think we can investigate from the two angles of being good at using hammers and being 1.8 meters tall. The victim Ma Zhongli is engaged in decoration design, and he is a relatively high-end designer. He should have contact with many decoration workers on the construction site. According to this
Rank your heights, maybe you can gain something."
The captain of the Fourth Brigade next to him swallowed the orange solution and gave a relatively reasonable scope of investigation.
The detachment leader said "En" and said, "Workers at the construction site are highly mobile, have weak legal concepts, and have good physical fitness. If they are looking for money, they do have this motive. Being good at using hammers is also a good point to ask. However, the construction site
It’s hard to define the scope of workers.”
“Ma Chung Lai mainly designs villas and large flats, and earns money from design fees.
Although he also went to the construction site, he did not come into contact with many workers. We have already inquired about the workers who have worked at the recent construction sites and those who have received wages.
"The captain of the first team shook his head lightly."
"There was no such judgment on height and skills before. We can check again and check more carefully."
The detachment leader still finds this direction very attractive and is not willing to give up easily.
The captain agreed and made a few sketches in his work notes.
It's easy to talk during a meeting, but it's more complicated when it comes to actually doing things. Even if it's to check on the workers, it's not easy to do it without leakage.
The team leader said, "As far as I know, Ma Zhongli often does some private work, and occasionally goes on business trips to other places. If they are workers from other places, it will not be easy for us to get together."
"You have to get closer even if you're far away. Otherwise, what should I do? I'll go find the police from other places for you and help you investigate?"
The detachment leader gave no excuses and forcibly pushed through the task.
The brigade leader sighed and nodded as expected. Anyway, when the time comes to approve the mission note, the detachment leader just needs to stop cheating.
"The murderer is not necessarily going after Ma Zhongli." Another criminal policeman waited for this topic to come up and said that judging from the murder cases in recent years, the most common motive for mass murder cases in rural areas is emotion, or emotion.
reason.
The main reason is the family conflict. Jiang Yuan judged that it was a home invasion and robbery, and the motive was to make money rather than people." Political Commissar Liu said calmly as a detective, "I have studied several murder cases that have occurred in recent years.
Almost without exception, the suspects have relatives or kinship relationships with the victim's family, and most of the reasons for the murders are family disputes, which everyone listens to very seriously.
Including the detachment leader, when he finished his speech, he also praised him and said, "Old Feng has studied it carefully. Indeed, the murderer killed four people in one breath. This case is too big. The purpose of simply embezzling money is not consistent with common sense."
.
In this way, Lao Feng, you lead your squadron and continue to dig along the line of kinship."
A dilemma encountered by the criminal police in Chiyong City is that many investigation directions have actually been investigated by them, but no clues were obtained before. Now that they are re-checking, it is still difficult to say whether there can be any breakthroughs.
However, no matter how difficult it is, the work must be distributed.
The detachment leader tried his best to make arrangements. At this time, no matter what he did, it was difficult, and the cost of solving the case was not considered.
But he still wasn't very confident about solving the case.
Jiang Yuan brought
Mu Zhiyang and others asked for an on-site investigation vehicle, and took along two on-site investigators from Chiyong City to begin on-site investigation of the crime scene.
Similar to an autopsy, much less information can be harvested during a secondary on-site inspection.
Some traces of the scene may have been collected, so that if you want to see the whole scene, you have to rely on photos.
However, the purpose of Jiang Yuan's coming here was just to experience the scene. From the moment he entered the door, he did not try very hard to clean his fingerprints, but instead focused on the traces of the murderers' actions.
Jiang Yuan has been simulating the murder processes of several murderers in his mind.
"These higher drawers were probably pulled open by this guy who is 1.8 meters tall. He was so strong that some of the drawers were broken. It's hard to determine which guy searched the lower drawers."
"The shuttle was opened with a sledge hammer."
"These guys are basically in the mode of violent disassembly, and they don't seem to have any lock-picking skills."
Jiang Yuan walked layer by layer and looked at each layer, constantly updating his ideas.
LV4's crime scene investigation, like his forensic pathology, is of a level beyond that of ordinary technicians.
However, it is still not easy to identify the murderer from the chaotic scene.
Even experts from ministries and commissions still have cases that they cannot solve.
The key is in the details.
If we can find some details that the murderer didn't find, and thus contact the identity of the other party, the case will be 90% solved.
Of course, this is just a beautiful expectation of technicians. Among the cases that are actually solved, there is only one case that can be solved through this method.
Most cases are solved in a somewhat foolish and inelegant way.
Jiang Yuan saw the hostess's room all the way. At this time, Chu Chen attracted Jiang Yuan's attention.
"There was something originally placed here, but it was taken away." Jiang Yuan stood in front of the closet. Using the light of his flashlight, he could see that there was a layer of dust inside. Only a rectangular area was free of dust.
Liu Jinghui immediately walked over to take a look and couldn't help but nodded and said, "It's quite big. Hmm. Small safe?"
This answer was a bit beyond Jiang Yuan's expectation. "How do you say it?"
Liu Jinghui said, "First, the size is right. Second, this is the hostess's room. I noticed that she doesn't seem to have a box or worm for jewelry. The jewelry and the like are probably put in this small safe."
.
Secondly, this family has two children and lives in a rural environment. It is indeed safer to put jewelry in a safe than in a jewelry box.
The main reason was that it was taken by mistake," said Mu Zhiyang: "In the end, the robber took away the entire safe."
"This kind of safe is what it is, it's convenient and simple, and it has a certain protective effect."
Mu Zhiyang said: "Is it possible that the jewelry box and the like were taken away by robbers?"
"No. You've seen movies about gold robberies. The robbers pour out the jewelry and take it away. Jewelry boxes are generally heavy and can't hold much jewelry, so the robbers won't take them away."
Mu Zhiyang nodded subconsciously.
Liu Jinghui continued, "You can ask insiders later. I don't think the hostess has any hidden intentions. Someone should know."
At this time, Jiang Yuan moved his chin and said nothing. After several people finished speaking, he said: "If it is a small safe, the way to open it is interesting."
Liu Jinghui immediately looked at Jiang Yuan.
Jiang Yuandao, "Among these three people, there should be no one who can unlock it. We just analyzed this. In this case, the person who gets the small safe will have no choice but to violently dismantle it."
"Well, it's impossible for them to call someone here just to open the lock. Not only will they pay for it in vain, but they might also leak the secret."
Liu Jinghui agreed, "Then is there any violent way to break it?"
“You can find cutting machines at any small project or even waste recycling place.”
Jiang Yuan paused and said, "But the other party should not dare to let them operate this kind of thing independently."
So just like unlocking a door, hiring someone means leaking secrets."
Liu Jinghui understood and asked, "You mean they want to open the safe themselves, what should they use?"
What?"
"Oxygen cutting machines are cheap and only cost a few hundred yuan. However, they probably don't have the patience to wait for online shopping, so..."
"They purchased an oxygen cutting machine locally?" Liu Jinghui nodded vigorously, "Yes, using this clue to investigate, the workload should be very low!"
