Chapter 757: Chapter 700 Clarifying Doubts

Qi Changye had just turned halfway around when, as if triggered by a mechanism, he pivoted back to his original position.

"Do you have any updated news?" Qi Changye had an excellent memory, capable of recalling the faces of his middle school classmates, and the scene of Jiang Yuan updating the news was vivid in his mind.

Jiang Yuan picked out a few photos, spread them out on the table, and said, "I’ll show them to you."

While speaking, Jiang Yuan pointed at a photo of a shutter door lock and said, "This rolling shutter was pried open with a special tool."

Next, Jiang Yuan lined up two photos of the ground lock devices and said, "From here, you should be able to see that the lock of the shutter door was pried open with a homemade Z-shaped steel plate combined with a hydraulic jack."

"Have you encountered a similar case?" Qi Changye asked, surprised.

"No," Jiang Yuan calmly denied and then explained, "That’s why I said it was Z-shaped, which is what I inferred from the marks on the ground. Actually, the principle of using a jack to pry open a rolling shutter is the same as that of a crowbar; this suspect has just standardized the lock-picking equipment and is likely to be quite skilled at it."

Qi Changye listened, somewhat perplexed.

Of course, he didn’t have Level 6 skills in trace tool identification, not even Level 1, so it was natural that he didn’t understand.

Seeing this, Jiang Yuan grabbed a piece of paper and sketched a force analysis on the spot, saying, "You can show this to a technician you’re familiar with. The characteristic marks left by jacking a rolling shutter door show that under the upward force F, the bottom edge of the shutter door will be squeezed and deformed by the Z-shaped steel plate, and you will see something different in the marks here..."

"To distinguish between a jack and a crowbar, the imprint of the base of the jack would usually be on the outdoor ground outside the rolling shutter door. It’s not visible in the photos, probably because it was swept away. But there were also no marks of a crowbar inside the door. Crowbar marks are generally hard to clean, so the absence of crowbar marks indicates the door was pried open with a jack."

Jiang Yuan’s explanation was a bit intricate, but Qi Changye understood it quite easily.

Moreover, Qi Changye asked with emphasis, "Does that mean that the methods used to open the rolling shutter door are limited to a jack or a crowbar?"

"Based on the marks on the shutter door, it’s generally either of the two. Especially the deformation at the lower edge of the shutter door, where you find indentations with bumps and depressions, these positions can reflect the end features of the Z-shaped steel plate," Jiang Yuan replied.

Having said that, Jiang Yuan confidently concluded, "If you can find this homemade tool and examine it under a microscope, you can definitely determine it’s the same tool!"

Listening to this, Qi Changye, no longer concerned with the technical reasoning, slapped his thigh and said, "I understand now; I’ll go look for this homemade tool right away. This person, could they be a professional at breaking into rolling shutters?"

"It’s possible," Jiang Yuan agreed.

If someone has gone to the length of making their own tools, they’re definitely doing so for frequent and convenient use. Therefore, it wouldn’t be wrong to suspect the thief specializes in breaking into rolling shutters.

Of course, there is more than one thief with such preferences. Especially in a place like Beijing, you never know when characters from all over the country might come to make a name for themselves. However, thieves skilled in using Z-shaped homemade tools are certainly not common.

Ordinary people might never encounter such individuals in their lifetime, and even those in the underworld may not know the specifics of their homemade tools, but there are always those who know.

To seek out this information, whether it’s Qi Changye or Tao Lu, detectives like them have their ways of investigation.

Qi Changye, full of enthusiasm, thanked Jiang Yuan repeatedly before hurrying off, pulling out his phone while walking, and swiftly sent out several messages.

The hallway was quiet, with the rhythmic tapping of keyboard keys sounding like the Grim Reaper at a disco.

Tao Lu watched Qi Changye’s back disappear, then closed the door again. Turning to Jiang Yuan, he shook his head and said, "You spoke too quickly. There’s actually no rush for this kind of case. To casually inquire about news or anything, it takes several days, so there’s no need to hurry in a matter of a moment."

Jiang Yuan was a bit slow to respond, "Because Director Qi said to update the news at any time..."

"You can update the news with Huang first. Doesn’t it seem like the updates are very timely here with me?" Tao Lu’s tone of complaint was tinged with a slight sense of injury as he took the opportunity to teach Jiang Yuan a lesson.

Jiang Yuan chuckled twice and replied, "I’ll mention it to Commissioner Huang, but, on this end, it’s just a theft case."

"Who knows what’s tied to a theft case. Even our criminal police cases involving breaking and entering to commit murder can be solved by following theft cases... Don’t be embarrassed because of his position. What, just because they have a high security level, they can freeload? If they’re capable, they should ask for their own resources, right? When I first started working, I even traded canned food with submarine soldiers. The radar station’s guys treated their meal with respect, and they talked politely with the forest police, didn’t they?"

Jiang Yuan felt it was different but then thought, why bother puzzling over it himself when he could leave it to Huang Qiangmin to consider.

Seeing Tao Lu emitting a faint air of resentment, Jiang Yuan immediately took out his phone and said, "Then I’ll give Commissioner Huang a call."

"Go ahead," Tao Lu smiled, turned around, and picked up the cadre mug, a porcelain cylinder straight as a gut, comforting to the soul.

Jiang Yuan made the call and quickly explained the situation.

Huang Qiangmin listened intently, "Mm," he said, "This indeed is new information, yeah, I’ll talk to Director Guan about it later, he knows more about this area. Hand the phone to Tao."

As instructed, Jiang Yuan handed over the phone, saying, "Tao, our Commissioner Huang would like to speak with you."

"Mm," Tao Lu took the phone and began, "Huang, I’ve noticed you’re being a bit sly... Yeah, uh-huh, huh?"

A few minutes later.

Tao Lu returned the phone to Jiang Yuan and said, "The call has ended, and if Qi Changye has more cases, I’ll help you communicate with him. I guess there will definitely be cases sent over, who wouldn’t smack their lips over such juicy meat, cough... What I mean is, Qi Changye’s cases also need to be coordinated and not just immediately done for him."

Jiang Yuan, as the son of Jiang Village’s wealthiest man, pretended not to hear the middle part, having long been accustomed to being the proverbial Tang Monk meat.

Jiang Yuan merely explained, "It’s because the scene in the photo was quite clear. Moreover, judging by the photo alone, it’s rather simple."

The difference between a one-stop solution and a reminder of the key issues is still quite significant.

Tao Lu responded with a "Mm," and said, "All in all, if Qi Changye contacts you again, just get in touch with me and Old Huang. Like today, you don’t have to hurry to throw out an answer."

"Alright," Jiang Yuan saw that Tao Lu was somewhat fixated and clarified, "We’re usually willing to do a case or two for new units."

"That’s not a bad strategy. Having tasted fine bran, one feels a sense of loss when going back to wild grass..." Tao Lu said, seemingly struck by a thought and falling temporarily silent.

After a long while, Tao Lu sighed and said, "Doctor Jiang, you should rest well today. Tomorrow, pick out cases with Liu Cheng; I’ve communicated well with Old Huang."
