Forensic Medicine Qu Xiaoshui

Chapter 525 The Betrayer: Shang Jingyi (4)

Qu Xiaoshui turned around, nodded to everyone present and said:
"Well, for example, the owner of the shoes needs to step on the accelerator or brake frequently. Because of too much force, the soles and toes will easily cause wear and tear. Especially for high-grade leather shoes, the degree of wear and tear will be even more serious."

In other words, the cheaper the shoes, the less likely they are to wear out.

Mi Yu nodded in agreement with Qu Xiaoshui's statement. He tapped the penholder in his hand and said:

"If the murderer is like what Qu Xiaoshui said, then this person should drive the vehicle frequently in a short period of time to cause such wear and tear. The murderer may even have a bad habit of burning out tires."

The miser Yan Yuanye doesn't understand what burning out tires is, after all, this is a hobby that costs money.

It was Bai Li who saw his look of seeking knowledge and helped explain:

"It's just stepping on the accelerator and stepping on the brakes at the same time."

She demonstrated personally:
"Put your left foot on the brake, step it all the way down, then put your right foot on the accelerator. Slowly lift your left foot off the brake."

She kept holding the steering wheel and said to Yan Yuanye:
"At this point the vehicle will be stationary, but the rear wheels will be spinning violently and the engine will be humming and roaring."

Bai Li showed a very enjoyable expression:

"If this lasts for a few seconds, the tires will rub against the ground violently, producing a lot of white smoke, and the tires will also make a squeaking sound that only occurs when the brakes are applied."

She took a deep breath, as if she could still smell the charming and stimulating smell:
"You can also smell the rubber smell produced by the heated tires in the nose."

Yep, you don't need to ask, this guy is also a tire burner.

This kind of hobby consumes a lot of tires, which means it costs a lot of money. Yan Yuanye, the miser, looked at the enjoying Bai Li and couldn't help showing a pained expression.

For the first time, he felt backed down from pursuing Bai Li.

Prodigal girls, what should I do if I feel that I can't afford to marry and go home? !

Bai Li didn't know that her little hobby made Yan Yuanye finally want to quit. If she knew it earlier, she would have done it already, okay? !

Mi Yu continued to tap the screen of the laptop with the pen, and pulled out the floor plan of the scene where Shang Jingyi's body was found, and covered it with the footprints collected from the scene:

"It can be seen from the images that the footprints at the scene are very neat and not messy. But from the damage to Shang Jingyi's clothes, it can be seen that she must have had a very fierce fight with the murderer."

Jiang Yue shrunk down the photos taken at the scene and placed them in the lower left corner of the screen, saying:
"That's right. Judging from the photos taken at the scene, the blood stains on the ground do not match Shang Jingyi's actual blood loss. Preliminary judgment shows that the place where Shang Jingyi's body was found is not the scene of her death."

Yan Yuanye looked at Jiang Yue, then at Mi Yu, and asked in surprise:

"You mean, after Shang Jingyi was killed, she was moved to the place where she was found later?"

"Yes." Jiang Yue nodded.

"I agree too." Ke Weixing quickly called up the surveillance video he had selected.

"This is the surveillance video I obtained after I hacked into a 300-hour sanitary supplies vending machine 24 meters away from the scene where Shang Jingyi's body was found." Ke Weixing tapped the keyboard quickly.

Before he synchronized the video to the big screen, he was afraid that everyone was expecting too much, so he gave everyone a thorough explanation:

"But only a few images have been taken, so don't expect too much."

After finishing speaking, he directly hit the Enter key:

"This is a picture taken around the early hours of that day."

After he used the mouse to drag the progress bar to the corresponding time, the video started to play.

A man wearing a black helmet, wearing a particularly cool black leather jacket that he wore when he started the car, and pushing a large suitcase, walked quickly past the vending machine.

The figure of the other party only appeared for a few seconds, and soon left the shooting range of the camera.

"That's the man in the helmet." Ke Weixing circled the figure of the man with a red graffiti pen.

This is the result of his painstaking investigation and a lot of monitoring, and the bitterness and inhumanity in it are not enough.

Thinking of this, Ke Weixing wanted to shed tears of sympathy for himself:

"This person is very cautious. There are obviously many surveillance cameras around, but none of them have captured his figure. Only this vending machine has captured his image. But he is still wearing a helmet, so he can't see his face at all."

The other party's degree of caution is at its peak.

Mi Yu pushed the laptop in front of him to the side, reached for Ke Weixing's computer, and quickly imported this video of the helmeted man walking with a suitcase into the gait authentication system.

He made a two-dimensional imitation of the man in the helmet and the no-parking signpost with black and yellow stripes placed on the roadside.

On the screen, the man's feet were leveled at the same level as the parking prohibition pile, and the man's bent waist was also straightened through data extension.

"The height of the parking prohibition pile is 70 centimeters." Mi Yu entered the data.

By the way, use the mouse to draw a red dotted line that connects the top of the helmet man's head with the top of the no-parking pile.

Mi Yu moved the horizontal line of the ground to the top of the helmet man's head, and quickly found an included angle:
"The included angle here is 23.2°, the distance between the man in the helmet and the parking pile is 245.6 centimeters, and the width of the parking pile itself is 38 centimeters."

As he spoke, he entered the data.

As Mi Yu pressed the Enter key, the real height of the man in the helmet was calculated.

"The height of the helmet man is 183 centimeters."

The height data of the helmeted man was instantly displayed on the screen.

Ke Weixing's eyes were straightened by Mi Yu's operation. He gave a thumbs up and said in admiration:

"Sure enough, awesome! You are too powerful!"

Ke Weixing's eyes are shining:

"The height of the man in the helmet is completely in line with Mi Yu's previous estimation of the murderer's height. This man should be the murderer without a doubt."

Mi Yu calmly returned the computer to Ke Weixing, stretched his arms, and pulled his computer back:
"I sampled the soles of Shang Jingyi's shoes. The dust left by her soles is slightly different from the scene, but it is not unique. It cannot be used to judge the places she has been to before her death."

Seeing that everyone nodded in understanding, he dropped another blockbuster:
"Also, I found a hidden SD card in the heel of her shoe."

The SD card was hidden very delicately. Shang Jingyi probably took out the insole by herself, hollowed out the heel from the shoe shell, stuffed the SD card sealed with kraft paper and plastic wrap into the heel, and then re-glued the shoe. posted.

From the appearance of the shoes alone, there is no problem at all.

It was only when Mi Yu was carrying out the identification of the attachments that the green laser light was used to find the inconspicuous traces of glue.

Only then did he disassemble the shoe, and after finding something inside, he took out the precious SD card from the heel of the shoe with tweezers.
