Forensic Medicine Qu Xiaoshui

Chapter 491 The Betrayer: Qin Gan (7)

Qu Xiaoshui didn't let them chat for too long, and quickly brought the topic back to the main topic.

She pointed to the ultraviolet photo of Qin Gan's face projected on the screen and said:

"Although it's not easy to identify, I feel that Qin Qian's nose and lips have slight subcutaneous bleeding. The murderer's strength is very delicate, so the marks left are very shallow."

Ordinary photos do not show any scars on Qin Qian's face, and only this kind of ultraviolet camera can reveal such subtle injuries.

As he said that, Qu Xiaoshui approached the screen, and drew two circles around Qin Qian's nose and mouth with a pen, outlining what she thought might be subcutaneous bleeding.

"Subcutaneous bleeding?" Mi Yu didn't look at the screen, but turned to look at Jiang Yue's computer.

In the ultraviolet photo, the marks on Qin Gan's face are really very shallow, and the dots are really hard to distinguish.

Mi Yu thought for a while, then said hesitantly: "Could it be that he accidentally bumped his nose when he was being raped?"

He said this because among all the marks, only the marks on the bridge of the nose were darker in color, and it could be seen that he had been under certain pressure or attack.

There are indeed some traces of what other positions have to say, but it is really a bit reluctant.

Qu Xiaoshui did not give up his deduction:
"Although the subcutaneous bleeding is very slight, the bridge of the nose has indeed been under pressure, so the marks are also the deepest. Come and take a closer look."

When Mi Yu heard this, he got up and walked to the big screen.

Photos that have been magnified countless times can make those inconspicuous injuries infinitely magnified.

This time, the closer observation made Mi Yu nod his head, and said affirmatively:
"You are right, this is indeed a case of subcutaneous bleeding."

Qu Xiaoshui breathed a sigh of relief.

Because he paid too much attention to this case, and the person who died was another person with such a special status.

Qu Xiaoshui inevitably felt a little out of balance, worrying about gains and losses.

Being affirmed, this made Qu Xiaoshui, who had always looked confident but not at ease, really relax a lot.

Qu Xiaoshui took the pen and connected the faint bruises with a line. The tip of the pen drew across Qin Qian's chin, cheeks, bridge of nose, then the other cheek, and finally stopped at the chin.The entire trace of subcutaneous bleeding is connected by a pen to form a closed structure, which can be roughly seen as an oval.

"After drawing it, it is more clear and intuitive. Can any of you see how these bruises were made?" Qu Xiaoshui stepped back a few steps, then turned around and asked.

Such a shape is so regular that it must be some kind of artifact to leave such a mark.

"It's like...the marks left by the oxygen mask...." Yan Yuanye drew the ellipse on the paper with a pen, and the more he drew it, the more he felt it, and he said it out loud.

As long as it was the tools and equipment that Yan Yuanye had seen, he would never forget them.

When no one thought of it, he immediately gave the answer.

This also made the people who had no clue at all finally get rid of the confusion. If they looked at the photo carefully, it really looked more and more like that.

"Don't say it, it's really similar." Ke Weixing gave Yan Yuanye a thumbs up.

Yan Yuanye was a little proud, but snorted arrogantly, pretending that he wasn't secretly happy at all.

He is not such a pleasing person!

Qu Xiaoshui nodded, accepting Yan Yuanye's statement.

She called up the autopsy report and said:
"During the autopsy, we found that the blood vessels all over the victim's body were subtly dilated. According to our preliminary judgment, it may be caused by the decrease in blood flow throughout the body. The murderer should have opened a new wound immediately after Qin Qian's wound stopped bleeding. , so that the blood has been flowing out, will cause such a situation."

Mi Yu also projected the information he had compiled on the screen, and his voice was a little cold:

"The murderer was very careful when committing the crime, and did not leave any complete footprints at the scene. The fingerprints on the clothes were also the victim's own."

Ke Weixing's voice was also a little low. He never stopped hacking into the network, even the shops on the side of the road, and found no useful information:

"The crime scene is in the basement of a vacant house. The surrounding area has not been fully developed, and there is no surveillance video installed on the nearby roads. The closest camera to the crime scene that I can retrieve cannot capture the people and people near the scene. The entry and exit of vehicles."

This makes Ke Weixing a little frustrated. Even if he is a god on the Internet, he can't do anything in places where the network cannot cover.

Seeing his dejected look, Yan Yuanye quietly gave him a piece of mint-flavored chewing gum.

Refreshing, it is also a small consolation.

"Qin Qian died eight days ago. It took two full days from his disappearance to his being found. When the police found Qin Qian, he was already dead," Bai Li said.

"I have checked the investigation records after Qin Gan's disappearance. The GPS and mobile phone he carried were abandoned by the murderer at the first time, and it took less than 3 minutes for him to leave the company and disappear from the police's monitoring sight. I There are enough reasons to believe that Qin Qian knew the murderer and was defenseless against him. Moreover, the murderer is very agile and can stop Qin Qian immediately. He also has a strong anti-tracking ability and can quickly evade the police Protective measures and various tracking arrangements for Qin Gan."

Everyone agreed with Bai Li's conjecture, and they were also shocked by such a conjecture.

"Currently, there is not enough information. I can't judge whether it is someone from that organization or 'my own'." Bai Li spread her hands, expressing that her ability has really reached its limit: "I need more information."

Everyone expressed their understanding.

If the person who did it was a member of that organization, it meant that Qin Gan's identity as an undercover agent had been exposed and he had been cleared.

If the person who did it was "one of our own", does that mean that Qin Qian may have betrayed?Or is it that the person who did it rebelled?
Qu Xiaoshui suppressed these doubts in his heart and continued to listen to everyone's discussion.

"I took a small sample of the clothing on the victim's body, and at the same time carried out the identification of the attachment." Mi Yu put on his glasses and casually placed the identification report on the table. He did a lot of useless work: "The attachment on the clothes No evidence related to Qin Qian's murder was found, and most of them were directly contaminated with dirt and dust at the scene of the crime."

And of course, there's blood.

Mi Yu skipped this point and continued:
"After comparing the blood DNA on the ground with the victim's blood DNA, it can be determined that most of the blood belongs to the victim himself."

"Not only that, I also checked the blood collected from Qin Qian's body that you sent out." Mi Yu said to Jiang Yue.
