"Dr. Cho, why are you only here to eat now? Xu Chengyan strode to Qiu Lan's side, and the voice of concern in his mouth rose and fell.

"Well, I'm just done, I'll buy something to eat, Officer Xu, aren't you eating now?" Qiu Lan raised her eyebrows lightly and shrugged her shoulders.

"I went to the female deceased's company in the morning to investigate the situation, and there were too many people, so it was a little late, but Doctor Qiu, you just got injured and can't be so perfunctory. Xu Chengyan looked at her gently, and a trace of worry flashed in his eyes.

After speaking, he handed Qiu Lan a set meal he had just bought, "Why don't we two change it, I just bought it, you eat something hot, don't eat sandwiches." ”

"No, Officer Xu, the sun is good now, I can still go to the sun with a sandwich." Qiu Lan softly rejected his offer and looked out at the bright sunshine.

"Well, well, we'll see you later. Xu Chengyan raised the corners of his mouth, and his eyes were a little different kind of emotion.

"Good. Qiu Lan nodded lightly and left.

But at this moment, in a corner outside the restaurant, a sneaky man is holding a high-definition digital camera in his hand, taking pictures of the two of them non-stop.

In the memory of this man's camera, there are still photos of Xu Chengyan and Qiu Yan in Clear Water Bay today.

At half past two in the afternoon, the Forensic Section, the Serious Crime Unit and the forensic staff gathered in the electronic conference room on the third floor.

This time, the case in Donglangshan is serious, which has attracted the attention of many people in the outside world, so the pressure on the public security personnel is self-evident, and they all hope to solve the case as soon as possible and find out the real culprit.

"Expert Cao, you can first explain to you the relevant information about Zeng Qipeng in Donglang Mountain yesterday. Xu Chengyan turned on the computer, projected the documents in the computer onto the screen, and then walked to the side, leaving the place to Cao Fan.

"Okay. Cao Fan picked up the controller in his hand and flipped the projection content, "Yesterday, according to Dr. Qiu's words, we sampled the board car at the scene of Zeng Qipeng's arrest, and found blood stains on the handle of the board car. ”

"The DNA extracted from the blood sample above is completely consistent with that of the female deceased, indicating that the cart was indeed a device that moved the female deceased from the two crime scenes, and it also confirmed that Zeng Qipeng had contact with the deceased. ”

"Yes. Qiu Lan pursed her red lips, slowly stood up, and affirmed his words, "The board car is made of wooden planks, because the long-term use of the wooden planks has caused different degrees of friction and deformation, so when the female deceased was lying on the board car and transferred, bruises with different degrees of force were formed on her back. ”

After listening to their analysis, Xu Chengyan frowned and said indifferently: "That means that this matter may be related to Zeng Qipeng." ”

"It's not just about it, it's what he did. Cao Fan's eyes sank, and he replaced the content of the projection with an identification report, "This is the DNA extracted from the semen and fluid found by Dr. Qiu from the female deceased, and it has been confirmed that it is the same as Zeng Qipeng." ”

"So I'm absolutely sure he's the one who raped and killed the dead woman. ”

"Yes, I agree with Expert Cao, and I have compared Zeng Qipeng's injured hand with the pressure marks on the deceased's face, and they are completely consistent. Qiu Lan nodded and showed the autopsy photos to everyone.

"Then we already have enough evidence that he killed the deceased and raped her after her death. Xu Chengyan carefully looked at the information in his hand and analyzed the words of the two, but he still had some doubts in his heart.

"But according to the autopsy report, the female deceased died suddenly of myocardial infarction, so why did he still injure the female deceased?

"No, it won't. Without a trace of hesitation, Qiu Lan directly denied his idea, and then took out another photo, "This is a trace found on the arm of the deceased, the same right hand, but it is complete, so there must be another person." ”

After speaking, she paused, took the controller in Cao Fan's hand, and changed the content of the projection, "And as Officer Xu said, if the female deceased is stunned, Zeng Qipeng will fight again It will be completely superfluous." ”

"If he had revenge because of his mental disorder, he wouldn't have known to beat him. Qiu Lan gently pressed the button of the controller and told the people in the conference room her thoughts.

"Actually, I have been thinking about the first question raised by Officer Xu for a long time. She took out a report from ten years ago and passed it to those present.

"This was a burglary case that year, and the deceased in the case was also hit in the head by a baseball bat, but the cause of death was a heart attack. Qiu Lan frowned and took a deep breath.

"The suspect at that time said that he saw the deceased suddenly wake up and immediately hit him, so the conclusion at that time was that the deceased had a heart attack at the moment when he was frightened and was hit hard at the same time. ”

After listening to Qiu Lan's analysis, everyone in the conference room understood what she meant, and nodded in agreement.

Dr. Qiu's words and previous cases have confirmed this problem. Xu Chengyan lowered his eyes, turned the information in his hand to the next page, and shifted his gaze to Cao Fan.

"By the way, Specialist Cao, did you find anything about the fibers that Dr. Qiu found on the deceased's body before?"

"No particular findings. Cao Fan shook his head lightly and took out the appraisal conclusion in his hand, "This is just an ordinary clothing fiber, which is very common in the market and has no direction." ”

"However, we have found something else, colleagues in the technology team have hacked the deceased's computer, recovered the backup data in it, and found some intimate photos in it, guessing that it should be the deceased and the deceased's boyfriend. ”

Hearing his words, Xu Chengyan and all the members of the serious crime team turned serious, with a trace of doubt in their eyes.

Looking up at the photos on the big screen again, the deceased and the man behaved intimately, and there were photos of kissing, and it was reasonable to say that he was a boyfriend.

"Boss, when Peipei and I were investigating the relationship between the female deceased in the company, no one mentioned that she had a boyfriend. Xiao Tiao held the pen and tapped lightly on the table, his tone a little heavy.

"yes. Pei Pei on the side echoed: "We haven't found out that the female deceased had a boyfriend, and isn't this weird? The news of the discovery of the body in Donglang Mountain has been reported, even if we didn't go to him, the deceased's boyfriend should have taken the initiative to find us, but he hasn't shown up yet." ”

"This is really suspicious, Pei Pei, Xiao Tiao, after the meeting, we must focus on investigating this man, if there is any suspicion, you can directly bring it back to the police station for questioning. Xu Chengyan's eyes sank, full of questions.

"The death of his girlfriend is such a big thing, and he hasn't reacted to it until now, it seems that he has a need to investigate. ”
