Rebirth of the open female forensic doctor

Chapter 682 Rock Climbing Equipment

"The physical evidence numbered ten, the footprints left on the outer wall of the apartment building where the deceased lived, the traces are too shallow, and only half of them are left. The technical team used the latest technical equipment to restore as much as possible..."

Ye Fan opened the technical report of the technical team. There was a picture of shoe prints printed on A4 paper. On the left was half of the shallow traces rubbed from the case, and roughly restored footprints through science and technology. On the right were three and restored footprints. The complete shoe print of shoes on the market with a high degree of footprint matching.

The following is the analysis report. Through various data comparisons, the coincidence rate of the first one on the right is 60.00% one, the second one is 60.00% five, and the third one is 50.00%.

"As you can see, these three shoe prints are more than fifty in terms of graphics, edges, and matching. The first and second are rock climbing shoes, and the third is traditional canvas shoes. The highest matching degree is this one. Rock climbing shoes from Y family."

Pointing to the second rock climbing shoe in the middle, Qian Qian explained in detail: "Rock climbing shoes are shoes specially designed and made for rock climbing. They are generally made of light, soft, and strong rubber soles, so that rock climbers can climb on the rock wall. It is better to use the pedaling action on the ground, and the design of the edge of the footprint from the field is more likely to be rock climbing shoes, especially the high-efficiency rock climbing shoes of the Y family.”

Ye Fan's slender fingers pointed on the footprints rubbed on the spot, and there was a faint trace in the middle of the sole, which was very consistent with the starting position of the Y-shaped imprint on the sole of the Y family's climbing rock shoe.

Below the sub-board map, there is also a piece of information about the Y family, which focuses on the efficient rock climbing shoes.

Y Home is a company specializing in outdoor sports brands. It is one of the most important brands in the Eurasian outdoor market. It is famous in Europe and Asia for its unique design and comfort. Its products cover clothing, footwear, tennis equipment, ski equipment, Rock climbing equipment, especially rock climbing equipment is recognized as a leading outdoor brand in Europe, Asia and even the world.

Rock climbing shoes are divided into three categories according to their appearance, full-featured, high-efficiency and climbing slippers. The high-efficiency type adopts a low-ankle design to increase the flexibility of the foot and reduce the weight of the shoe. The bottom also has a radian change, which is consistent with the case. The marks on the half of the footprints at the scene matched very well.

However, at the heel of the back foot, there are two small circles in the footprints at the scene of the crime. However, among the several rock climbing shoes currently on the market of the Y family, none of the soles fit the bill.

The first pair of shoes with a matching rate of 60.00% comes from another emerging outdoor brand. Currently, they only make hiking, cross-country and rock climbing equipment. Cute cat paws, the two small dots in the three-finger small paws can print small circle blanks.

The footprints rubbed on the spot were too vague and incomplete. It was not easy to find such a high degree of pattern matching in such a short period of time. Thanks to the serial beheading murder case that was solved before, Lucheng Criminal Investigator The brigade is well-known throughout the country, and is highly valued by the superiors, and all kinds of latest equipment can be applied for one by one.

The equipment of the technical group and the forensic group were almost all shotguns replaced by cannons, otherwise the report would not have been released in such a short time.

"The black substance under the cobblestone bench on the roof is also from the ropes in the rock climbing equipment?" Ye Fan turned to another inspection report marked [-] below. It was she who didn't sleep at night and went to the scene of the crime for a while. After the circle, a black substance was found at the bottom of a stone bench column on the top of the building.

"That's right." Qian Qian looked at Ye Fan with two big bags under his eyes, and said sadly, "It's all thanks to you wandering outside in the middle of the night."

As soon as this remark came out, everyone in the office cast their eyes on Ye Fan. Now, whenever there is a big case, they can't sleep well at night, because of her hobby, although there must be Great discovery, but really hurtful.

"Uh, my fault, my fault." Ye Fan scratched his head embarrassingly, and said; "I promise, try to avoid it in the future."

"Okay, stop joking, Qian Qian, keep talking." Chang Dui twitched the corners of his mouth and tapped on the whiteboard with an oil-based pen.

Although Qian Qian became the team leader, his temper was still so jumpy, and he blinked at Ye Fan before continuing: "Dyneema-strength polyethylene fibers were detected in the black substance, the general label is 22KN, and the melting point is 145 degrees. The advantages are light, Wear-resistant, strong, not easy to absorb water, especially suitable for use in winter or ice climbing."

"The technical team compared the rope products of several rock climbing brands, but they haven't found the exact same product yet. We need to collect more samples for comparison before we can be sure."

This result, everyone is somewhat disappointed.

In the gloomy atmosphere, Ye Fan's clear voice sounded like a stream: "At least we can confirm that the murderer climbed from the roof to the bathroom of the deceased with a set of rock climbing equipment. This person is most likely a rock climber. Only such professional equipment."

"Why can't it be bought temporarily?" Qian Qian questioned. It is very convenient to buy these things now, and the physical evidence left at the scene cannot detect the newness of the equipment used.

"You're stupid." Without Ye Fan's answer, Han Han slapped him on the back of the head, rolled his eyes and said: "Professional equipment such as rock climbing ropes seems simple, but for those who don't understand it, there is no I can’t control it, otherwise why would I need to call professional police officers to collect evidence at the scene of the crime that day.”

"Let's talk about rock climbing shoes. In order to concentrate the power on the thumb so that you can step on the small foothold on the rock wall, the design will squeeze the toes in the direction of the thumb. People who have not worn them are not used to wearing them at all. The murderer Fei The purpose of breaking into a house is to kill people, not to really want to climb rocks, why do you have to wear a pair of shoes you are not used to."

"That's right, it makes sense." Qian Qian scratched the back of her head where she was photographed, and gave a smirk.

Team Chang wrote rock climbing enthusiasts on the whiteboard, followed by rock climbing shoes and climbing ropes.

Ye Fan looked at the inspection report and reminded: "The size of the shoes is about 36 to 38, and the rope is black."

Due to the incomplete footprints at the scene, the technical team simulated and restored them through special equipment, and it can be roughly inferred to be between 36 and 38 yards.

The regular team made another note on the back of the climbing shoes and climbing ropes.

Xia Dong looked at the size of the shoes and said thoughtfully: "This size is more like a woman's size, and the size of an adult man should be a very small size."

"Not necessarily." Chang Dui shook his head and said, "I have also learned rock climbing. In order to better exert strength on the rock wall, rock climbers usually choose shoes that can tightly cover the feet. Smaller than normal shoe sizes, professional climbers even go for sizes that are much smaller than their usual size, so you can’t judge men or women by that.”
