Chapter 355: Details

"Actually, just looking at Jiang Yuan's side, that is, the suggestions from the Shannan side, I feel that we can already try to do a screening."

Liu Zhengwei spoke in the middle of the meeting, cutting off the lively discussion.

Anyone with a discerning eye could see that the information Jiang Yuan sent over was indeed enough to meet the basic conditions for screening.

But Jiang Yuan had only been here for one day, and they were starting a large-scale screening now? "We have to define a scope." The detachment leader lowered his head and peeled an ugly orange.

The ugly orange was sent by the criminal investigation director, Xu Ju, who hadn't come to the meeting, but for the past few days, the director had been sending fruit over, and the value was getting higher and higher, making people's mouths bitter.

Several brigade leaders beside him all received oranges distributed by the detachment leader.

The orange was sweet, the juice was abundant, and people's tolerance kept rising.

Indeed, compared to a little bit of face, the director and such were the truly terrifying ones.

"I think we can screen from the two angles of being skilled with a hammer and being 1.8 meters tall. The victim, Ma Zhongli, was an interior design designer, and a relatively high-end designer at that. He should have come into contact with many construction workers. If we screen according to this height, we might have some gains."

The brigade leader of the Fourth Brigade beside him swallowed the orange and gave a relatively reasonable screening scope.

The detachment leader gave an "en" and said: "Construction workers have high mobility, weak legal awareness, and good physical fitness. If it's for money, they indeed have this motive. Being skilled with a hammer is also a good point to ask about. However, the scope of construction workers is not easy to define."

"Ma Zhongli mainly did design for villas and large flat-floor apartments, earning design fees.

Although he also went to construction sites, he didn't come into contact with many workers. We have already questioned all the workers who worked at the recent construction sites and those who received wages."

"The brigade leader of the First Brigade shook his head slightly."

"Before, there were no such judgments on height and skills. We can re-screen and check more carefully."

The detachment leader still felt this direction was very attractive and wasn't willing to give it up easily.

The brigade leader agreed and ticked a few marks in his work notebook.

It's easy to talk during a meeting, but it's complicated when actually doing things. Even just screening workers, how easy is it to do it flawlessly?

The brigade leader said: "As far as I know, Ma Zhongli often took on private jobs and occasionally went on business trips to other places. If they were workers from other places, it wouldn't be easy for us to gather them here."

"Even if they're far away, we have to gather them. Otherwise, what can we do? Should I go find police from other places to help you screen?"

The detachment leader didn't give any excuses and forcibly pressed the task over.

The brigade leader sighed and nodded as expected. Anyway, when it comes time to approve business trip slips, the detachment leader shouldn't go back on his word.

"The perpetrator might not necessarily have been aiming for Ma Zhongli." Another criminal police officer waited for this topic to land and said: "Looking at extermination cases in recent years, the most common motive for rural extermination cases is still emotion, or rather, emotional reasons."

"The main reason is family conflict. Jiang Yuan's judgment is home invasion robbery, with the motive of money rather than people." Liu Zhengwei said a calm type of criminal police: "I have studied several extermination cases that occurred in recent years. Almost without exception, the criminal suspects have a relative or kinship relationship with the victim's family, and the reason for the perpetrator's killing is mostly family disputes." Everyone listened quite seriously.

Including the detachment leader. After the speech ended, he also praised: "Old Feng has studied it seriously. Indeed, the perpetrator killed four people in one go. This case is too big. A simple purpose of invading property doesn't quite fit common sense."

"In this way, Old Feng, you take your squadron and continue to dig along the line of kinship."

A dilemma encountered by the Chiyong City criminal police is that many investigation directions have actually been investigated before, and no clues were found. Now, re-verifying whether there can be a breakthrough is still hard to say.

However, no matter how difficult, the work had to be distributed.

The detachment leader arranged as best he could. By this time, everything was difficult, and the cost of solving the case was not even in the scope of consideration.

But regarding solving the case, he still didn't have much confidence.

Jiang Yuan took Mu Zhiyang and others, asked for a crime scene investigation vehicle, and took two Chiyong City scene investigators along to start the crime scene investigation.

Similar to the autopsy, the second crime scene investigation could yield much less information.

Some traces at the scene might have been collected, so to see the full picture of the scene, one had to rely on photos.

However, Jiang Yuan's purpose in coming was to experience the scene. From entering the door, he didn't try very hard to wipe fingerprints or anything, but focused on the traces of the perpetrators' actions.

Jiang Yuan had been simulating the process of the crime by the perpetrators in his mind.

"These higher drawers should have been pulled open by the 1.8-meter guy. He has great strength; some drawers were even broken. It's not easy to determine which guy searched the lower drawers."

"The drawers were pried open with an octagonal hammer."

"These guys basically used a violent dismantling mode; it seems they didn't have any lock-picking skills."

Jiang Yuan walked layer by layer, looked layer by layer, and constantly updated his thoughts.

lv4 crime scene investigation, like his forensic pathology, has a level that exceeds that of ordinary technicians.

However, it is still not easy to parse out the perpetrator from the messy scene.

Even experts from the ministry still have cases they can't solve.

The key lies in the details.

If one can find a detail that the perpetrator didn't discover, and thus connect it to the other party's identity, the case can be considered 90% solved.

Of course, this is just a beautiful expectation belonging to technicians. In truly solved cases, cases that can be solved in this way are one in a hundred.

Most cases are solved in a somewhat clumsy, ungraceful way.

Jiang Yuan looked all the way to the hostess's room. At this time, a patch of dust attracted Jiang Yuan's attention.

"Something was placed here originally, and it was taken away." Jiang Yuan stood in front of the wardrobe, borrowing the light from the flashlight, and could see a layer of dust accumulated inside, except for a rectangular area that had no dust.

Liu Jinghui immediately walked over to look and couldn't help but nod: "It's quite big... Hmm... A small safe?"

This answer was a bit beyond Jiang Yuan's expectation: "How so?"

Liu Jinghui said: "First, the size is appropriate. Secondly, this is the hostess's room. I noticed that she doesn't seem to have a special box or container for jewelry here, so jewelry and such might have been put into this small safe."

"Secondly, this family has two children and is in a rural environment. Putting jewelry in a safe is indeed safer than putting it in a jewelry box."

"It also mainly serves as a mistake in taking." Mu Zhiyang said: "As a result, the robber took the whole safe."

"This kind of safe is like this originally, convenient and simple, and it's enough to have a certain protective effect."

Mu Zhiyang said: "Is it possible that the jewelry box and such were taken by the robber?"

"No. Have you seen robbers in movies robbing gold shops? Robbers all pour out the jewelry and take it. Jewelry boxes and such are generally heavy and can't hold much jewelry, so robbers won't take them."

Mu Zhiyang nodded subconsciously.

Liu Jinghui continued: "We can ask someone in the know later. I see this hostess didn't have the intention to hide it, so someone should know."

Jiang Yuan rubbed his chin and didn't say anything. After everyone finished speaking, he said: "If it's a small safe, the way to open it is interesting."

Liu Jinghui immediately looked at Jiang Yuan.

Jiang Yuan said: "Among these three people, there shouldn't be anyone who can pick locks. We analyzed this just now. In this way, the person who got the small safe could only dismantle it violently."

"En, they couldn't have specifically called someone over to pick the lock. Not to mention sharing the money for nothing, it might also leak the secret."

Liu Jinghui agreed: "Then what violent dismantling method is there?"

"Find a small project, or even a place that recycles waste, and you can find a cutting machine."

"Jiang Yuan paused and said: "But for this kind of thing, the other party shouldn't dare to let them operate independently."

"So like picking a lock, asking someone means leaking the secret."

Liu Jinghui understood and asked: "You mean they want to open the safe themselves, with what?"

"Oxygen cutting machine, a cheap one only costs a few hundred yuan. However, they shouldn't have the patience to wait for online shopping, so..."

"They purchased an oxygen cutting machine locally?" Liu Jinghui nodded continuously: "That's possible. Use this clue to screen, the workload should be very low!" ===== CHAPTER 356 =====
