While Ni Cha went to make a phone call, Jiang Yuan, accompanied by Zhong Renlong, thoroughly searched the entire room and then went upstairs to check the rooftop.
There were many more footprints left on the rooftop.
Outside of the China area, criminals don’t pay much attention to footprints. Mainly because not many people get caught because of them, criminals in the prison "The Great Learning" cannot learn relevant counter-detection techniques. They don’t really study, let alone gather information from abroad.
By the ti Jiang Yuan reached his level, footprint identification was like DNA analysis more than 20 years ago. As long as blood, sen, and hair were collected in a case, it was straightforward.
Jiang Yuan carefully examined the footprints on the rooftop, looked at the ropes and other items left behind, and then turned to Zhong Renlong, saying, "This rope-tying technique should be quite special. Can it be traced?"
"It’s the SWAT team’s tying technique," Zhong Renlong responded in a low voice.
They had just investigated this information.
Don’t look at rappelling as just tying a rope and jumping down, as a tactical subject, it’s actually extrely difficult. From equipnt configuration, rope inspection and maintenance, how to choose weight-bearing fras, various rope-tying thods under different circumstances, to rappelling techniques and strategies to deal with special situations, even the average active military or police may not be able to complete it at a high level.
For example, in a National Day parade rehearsal, the Indian special forces failed in rappelling, resulting in three people falling.
In theory, special forces should be the top-trained units. The National Day parade should be the best of the best. During rehearsal, training should be complete and at its peak. Yet, they still fell because of India, but it also indicates from another perspective that rappelling is indeed difficult, at least more so than 18 people riding one motorcycle.
The rappelling rope on the rooftop itself is evidence, where it ca from, how it was acquired, etc. All are clues. Likewise, choosing where to tie the rope, what tying technique to use, speaks volus.
Selecting the most sturdy bindable object on-site is an ability.
So are so skilled they even have the ability to temporarily modify a fra.
Otherwise, an 80-kilogram man, if careless, with the force generated by gravitational acceleration and a strong kick, if tied to a small steel bar, might quickly find his head needing a steel shell.
"The killer must have stayed here for a while," Jiang Yuan followed the footprints to a sheltered spot on the rooftop.
There was a square protrusion here, about two ters in height, and three ters in length and width, with things like ventilators inside.
Jiang Yuan had people take pictures of the ssy footprints on the ground, then carefully searched the walls and said, "Call soone to brush this wall. See if you can detect any fibers. If you can find sweat stains or the like, all the better. The killer waited here, leaning against it for so ti."
Zhong Renlong nodded repeatedly and then used the walkie-talkie to call the technician up.
In general, for small cases, police from various countries don’t like to use trace evidence. The cost of use can be exorbitant. Brushing a few spots on this wall can cost tens of thousands, with no guarantee of results. But in this case, it doesn’t matter how much the expenses are; no one would bat an eye.
If, as Jiang Yuan said, they could find sweat stains, DNA identification would basically nail the suspect. Even if only textile fibers were found, that’s quite good. Matching the perpetrator’s clothing, etc., counts as fairly strong circumstantial evidence.
After examining the rooftop, Jiang Yuan walked down again and let Wang Chuanxing add more information: "The killer’s stride on the rooftop is smaller compared to his leg length, which should be deliberately trained. This reinforces the idea that he’s in a trained state..."
"You can tell leg length too?" Zhong Renlong just put down the walkie-talkie and felt like he heard sothing incredible.
Jiang Yuan naturally nodded, "The steps inside the bedroom are normal, revealing leg length, while the steps on the rooftop are deliberately trained steps..."
"Oh..." What could Zhong Renlong say? Just quietly noted it down. Next ti, if there’s a case requiring a detective to figure out leg length, he’ll know to find Jiang Yuan.
"The killer lingered on the rooftop for a while, waited for the right mont, and without much hesitation, found the best spot to tie the rope and then rappelled down. From the footprints on the rooftop, the killer did not collect necessary information, indicating an accomplice provided him with information, or there was an insider," Jiang Yuan continued his deductions.
Zhong Renlong quickly took notes, feeling that the pressure of solving the case had sowhat lessened.
Jiang Yuan continuously revealed line after line of clues. Even if half of them led nowhere, the remaining ones were quite useful.
Below, Ni Cha also felt hope. In such cases, the biggest fear is drawn-out ti, and the second is having no leads and progress early on, leading to wild attacks from dia reporters.
With soone like Jiang Yuan providing a large amount of lead at once, even if the case couldn’t be imdiately solved, it still allowed room to breathe.
Sotis, they might even receive a asure of praise.
Jiang Yuan finally finished investigating the scene and then returned to the forensic doctor’s autopsy room with the body. The Brit-styled Jacob was already waiting there.
He gracefully took Jiang Yuan’s coat, handed him a white lab coat, and cheerfully said, "A parliantarian’s body, quite rare. How shall we dissect it?"
"Follow the usual process, but be more thorough with so things, do a comprehensive toxin test." Jiang Yuan had already done an external examination and wasn’t too demanding regarding the autopsy itself.
Based on the cri scene, the killer was very decisive, and not much interaction occurred with the victim. It’s likely it ended with a quick stab to the neck.
Under such circumstances, the body might not offer much direct evidence. Comparatively, toxin testing could provide insights into the victim’s state at the ti. Whether they took sleeping pills, were addicted to drugs, or poisoned, etc.
Jacob quickly agreed and led Jiang Yuan to the body, eyeing the prone parliantarian with the knife in hand.
"Quite chubby, not easy to cut," Jacob lightly patted the parliantarian’s belly, which was as bouncy and soft as a fresh block of aged tofu.
"Cut and see," Jiang Yuan took a scalpel and drew a long ’I’ from the center of the corpse’s body.
However, unlike usual, the abdominal fat of the deceased was so thick they couldn’t cut through.
So, soone had to stand aside and use their hands to push aside the blubber while making cuts, clear the fat, and cut again... again.
The parliantarian, often showing a big belly, had abdominal fat so thick that Jiang Yuan needed to make three incisions to see the structure beneath.
Jacob’s eyes widened, holding the abdon fat of the parliantarian, trying to make it as easy as possible for Jiang Yuan to cut.
