Forensic Medicine Qu Xiaoshui

Chapter 524 The Betrayer: Shang Jingyi (3)

Yan Yuanye took over from Mi Yu the work of identifying the wounded device and the rifling of Zi Gongdan.

It was the first time for him to do this appraisal alone. Although he had seen Mi Yu do it many times, Yan Yuanye was not careless, but very serious.

He even dug out the surveillance video of Mi Yu's past experiments, and compared them while conducting identification.

No bow single shell was found at the scene, and four somewhat deformed sub-bow single heads were clamped out of the stainless steel tray by Yan Yuanye, and placed in separate petri dishes one by one.

Then these bow heads were observed under a microscope, and the bow single marks were scanned into data at the same time, compared with the data of past cases in the database to check whether the gun that shot Shang Jingyi had a past criminal history. .

Ke Weixing tried his best to investigate the surveillance video around the scene and the suspicious people photographed.

All the rest of the work of sorting out evidence and collecting data fell on Bai Li alone.

The burden was a bit heavy, but no one complained.

When everyone was sitting in front of the big screen with disheveled faces, Qu Xiaoshui gave everyone a bottle of Wahaha AD calcium milk.

Qu Xiaoshui put a bottle on the table in front of everyone, then took a bottle for himself, and said:

"Drink."

Bai Li was a little disgusted, she held her chin with one hand, looked at the AD calcium milk that Qu Xiaoshui had thoughtfully inserted into the straw, held the bottle with two slender fingers, shook it in front of her eyes, and said:

"This kind of thing that children only drink, who bought it?"

Qu Xiaoshui was silent, and replied blankly:
"I bought it."

Bai Li immediately changed her expression, and put down Erlang's legs, which were originally charming, and boasted solemnly:

"It's really good. It's sweet and sour. It looks delicious."

The other men looked at this scumbag with contempt on their faces, their position was really too unstable!
Like them, man!man!If you don't drink, don't drink!
Seeing that no one was drinking, Qu Xiaoshui rolled his eyes:

"Don't patronize and dislike."

She touched everyone's heads one by one with her fingers, and said unhurriedly:
"You guys often stay up late lately, you probably don't have a smooth time going to the toilet, right?"

Everyone nodded in unison.That's right, everyone has been a little angry recently, feeling uncomfortable, and unable to go to the toilet.

The old god Qu Xiaoshui sat back in his seat, leaned back on the back of the chair, and relaxed his muscles.She shook the AD calcium milk in her hand:

"It contains beneficial bacteria that can promote gastrointestinal motility and help excretion; there are also special amino acids that can enhance immunity, calcium and milk that can strengthen bones and teeth..."

As soon as Qu Xiaoshui said this, he saw that several big men who were still disgusted and didn't want to move put straws on the AD calcium milk in front of them.

Um!So fragrant!

I took a big sip, um, it was sour and sweet, and it really had a childhood taste.

Qu Xiaoshui waited for everyone to finish their drinks before announcing the start of the meeting.

Bai Li first introduced Shang Jingyi's background.

At the same time, her recent photos and previous photos were projected on the big screen.

Everyone was taken aback by Shang Jingyi's personal information and past commendations.

The long list of awards tells everyone that this is a very good policewoman.

Born in the armed police, he has performed many top-secret missions, and later won the No.1 in shooting and fighting in the national police competition.

When Bai Li said this, she paused for a moment. She called up a photo of Deng Jianshan, and drew a straight line between his photo and Shang Jingyi's photo:
"Not only that, but she also served as a special training instructor for outstanding students at school, and Deng Jianshan was one of the students she mentored."

Qu Xiaoshui nodded, and after Bai Li finished introducing the background of the case, she announced Shang Jingyi's autopsy report:

"The time of Shang Jingyi's death is beyond doubt. The murderer killed Deng Jianshan the day after she was killed."

Jiang Yue helped to retrieve the photos taken during the autopsy:

"Shang Jingyi's shoulders, arms, and thighs showed signs of being beaten, but the actual cause of death was due to a bullet shot into the body, causing organ damage and death caused by excessive blood loss."

Qu Xiaoshui looked at Yan Yuanye:

"Has the murder weapon been identified?"

Yan Yuanye immediately called out the injury device report, and connected the big screen with the tablet in his hand:
"Judging from the shape of the wound, the knife wound on Shang Jingyi's arm was caused by a special dagger with a blade length of more than 14 centimeters. The width of the dagger is about 3.2 centimeters, the thickness is less than 5 millimeters, and there are barbs on the back of the knife. When pulled out, the skin and flesh of the wound will be turned outward, and the wound at the wound will be enlarged. For the other four wooden warehouse wounds, I have compared the rifling of Zigongdan with the previous criminal records in the database, and I have not found anything else for the time being. .”

Mi Yu nodded to Yan Yuanye, and was very satisfied with the appraisal results Yan Yuanye completed alone. He also projected his results on the big screen:
"Among the items left at the scene, no fingerprints of the murderer were detected. I suspect that the murderer should have been wearing gloves when he committed the crime."

He called up the footprints collected from the scene:

"There are two kinds of shoe prints left at the scene, excluding the shoe prints of the deceased, and the other is the footprints left by men's leather shoes of size 44."

Ke Weixing looked at the two kinds of footprints and muttered:

"The latter is the shoe print of the murderer, right?"

Mi Yu turned his chair, stretched his neck, and nodded:
"It's very possible."

Then, he tapped the keyboard of the laptop in front of him with one hand, speaking slowly, and said clearly:

"Based on the size of the steps estimated from the footprints left at the scene, it can be inferred that the murderer's height should be between 180 cm and 185 cm."

He tapped the screen: "I'm more concerned about the degree of wear on the soles of his shoes."

Mi Yu zoomed in on the male footprints on the screen:

"You can see that the shoe prints on the right foot are shallower than those on the left foot, and the left and right footprints of the murderer are asymmetrical."

Bai Li nodded:
"Indeed, the toe of the right foot is severely worn."

Mi Yu is very talkative today, agreeing:
"Well, this should be caused by the murderer's walking habits."

Qu Xiaoshui walked to the screen, carefully observed the difference between the footprints of the left and right feet, thought for a while and said:

"Actually, there is another possibility."

Mi Yu pushed the glasses on the bridge of his nose, thought for a few seconds, and showed a dazed look:

"Indeed, there is another possibility."

Everyone focused their expectant eyes on Mi Yu.

Mi Yu seems to be extra patient today, he explained:
"Another possibility is because of professional needs."

Seeing that both Yan Yuanye and Ke Weixing showed puzzled expressions, Mi Yu zoomed in on the footprint of his right foot on the screen:
"The wear of the soles may also be caused by excessive force and continuous friction in daily life."

"Continuous friction?" Ke Weixing repeated.
