Speculation arose, and Lin Chenxing remained silent from Lian.

Yes, all the physical evidence is complete, only human evidence is lacking, and Lin Chen doesn't even suspect that there may be any witnesses who have witnessed Duan Wanshan in two days.

The current situation is very interesting, they are surrounded by colleagues and comrades-in-arms who have always supported them, but they can't tell each other that Duan Wanshan is really dead, so you all guessed wrong.

Lin Chen couldn't help coughing, this kind of enemy feeling in the dark and in the light was really not good, and these conspiracies actually revolved around the dead Duan Wanshan, which felt even more unacceptable.

The criminal conglian cast a concerned gaze, Lin Chen looked at the other party's eyes that looked a little dark under the incandescent lamp, and said, "Let's go to the forensic office?" ”

"Okay."

……

The medical examiner at the Hongjing Police Station is a lady with a bright red wavy hair.

When they arrived at the door, the forensic doctor was holding milk tea and carrying a bag ready to leave work. The convict pressed down on the door and pushed the man back into the office.

"Hey, I like girls, stay away from me." Forensic Doctor Yu shouted.

"It's okay, I like men." Torture Conglian said.

Lin Chen pushed the door in, only to see that the criminal Conglian was pressing the forensic lady in the chair, snatching the bubble tea from the other party's hand, and throwing it into the trash can accurately.

"Torture from your sister!"

"Why are you in a hurry to get off work?" The torturer asked sharply.

"Damn, it's seven o'clock in the evening now, and I've been working overtime for two hours, okay?"

"Then sit down a little longer."

The torturer dragged a chair as he spoke, and Lin Chen sat down and greeted the beautiful lady in front of him: "Forensic Doctor Yu." ”

"Advisor Lin."

"What are the methods of falsifying DNA evidence?" Lin Chen asked bluntly.

"Advisor Lin!"

Forensic Doctor Yu's face sank: "It's okay if you don't let me get off work, why did you suddenly come here to ask such a strange question!" ”

Lin Chen said: "We suspect that the DNA sample belonging to the suspect Duan Wanshan on the murder weapon in the Stancom case was faked. ”

For a long time, Forensic Doctor Yu did not speak. The smell of formalin floated in the air, and the smell of fresh gel water from the forensic redheads.

"What do you mean?" The forensic doctor cocked his legs and straightened his face.

Lin Chen replied: "Duan Wanshan has been abroad all the time, and there is no entry record, so it is impossible for him to suddenly appear in Hongjing to kill people." ”

"You guys who are engaged in criminal investigation should be able to find hundreds of methods and possibilities for him to come back." Forensic doctor Yu said.

Lin Chen said succinctly: "Impossible. ”

"Well, according to what you said, even if someone framed him and stole a sample of his blood and put it on the hilt of the knife." Forensic Doctor Yu changed to one side and cocked his legs.

"It can't be."

"Why?" The female forensic doctor leaned forward suddenly.

"I can't tell you just yet."

"You're trying to kill me." Forensic Doctor Yu leaned back in his chair, looking like I had just been tested, what could you do with me.

Lin Chen continued to press: "So, we need a possibility, a possibility that Duan Wanshan has nothing to do with this matter, but a blood sample containing his DNA will appear on the handle of the knife." ”

The red-haired female forensic doctor looked awe-inspired, and her willow eyebrows raised high: "I understand, do you want me to tell you that there is any way to falsify DNA evidence?" ”

"Yes."

"Have you ever thought about how much pressure the prosecution will be put on the prosecution in future court debates if there is a typical case of DNA evidence falsification, and countless defense lawyers will use this to attack the reliability of forensics?" Forensic Yu asked rhetorically.

"But this is an unavoidable question, and in this case, I am very sure that there has been a falsification of evidence." Lin Chen insisted.

Finally, Chief Forensic Doctor Yu let out a long sigh and said, "It's actually very simple. ”

"How easy is it?"

"Let's say, I can get your DNA sample, and I don't need much, even a single hair of yours. Amplify a large amount of DNA through PCR technology, then draw a tube of old torture's blood, pass a centrifuge to isolate the white blood cells containing DNA, and then add your DNA to the blood of the old torture......"

Lin Chen looked directly at the forensic doctor: "That tube of blood has been forensically appraised, and it will only belong to me, not to him." ”

The beautiful female forensic doctor nodded solemnly: "This is just the simplest technique, and biology undergraduates can complete it." ”

"I see." Lin Chen stood up and saluted, "Thank you." ”

"You questioned my results and said thank you and wanted to run?"

Lin Chen lowered his eyes and said to Forensic Doctor Yu, "Actually, I still have one more thing I want to know. ”

"Your eyes are very damning." Forensic doctor Yu crossed his arms to look at him.

"It dawned on me that there was something you hadn't made clear to us." Lin Chen said lightly, "Although I don't know the specific division of the gene pool, I am still surprised that you can find out that it is Duan Wanshan's DNA so quickly." ”

"Damn, you're doubting me!"

"I'm looking for answers."

Forensic Doctor Yu stared at him for three seconds, took a long breath, took off the headband from his left wrist and tied his hair high, took out a notebook from his backpack, and opened it with a snap: "Do you know the Dingyuan Forum?" ”

Lin Chen frowned: "Medical forum? ”

"It is the largest medical-related forum in China." Forensic Doctor Yu turned on the computer, "I'm a sub-forum administrator, so I basically go up every day to deal with station affairs. Forensic Doctor Yu paused, "I explain this to tell you that I'm not stirring up trouble. ”

Lin Chen nodded.

"It's not the style of painting if I want to really stir up trouble." Forensic Doctor Yu clicked on the forum, typed the keyword "plagiarized Stankang" in the search box, and then pressed the enter key, "About a month ago, someone posted a post suggesting that Stancom plagiarized Duan Wanshan's research results, because both of them are academic experts, and the discussion was quite enthusiastic. However, the landlord did not provide any key evidence, and it was gone. ”

Lin Chen's heart sank, and he finally realized where the uneasiness in his heart came from. If the other party designed to frame Duan Wanshan, it would definitely make a complete chain of evidence, in addition to physical evidence, it should also contain the motive for killing, and now that there is this post, the motive for killing is about to come out.

Duan Wanshan was plagiarized by Stancom because of his research results, held a grudge, and returned to China to murder Stankang.

"After Stancon's death, this post was pushed up again by people with a heart." Forensic Doctor Yu said meaningfully, "You know ......"

The convict Lian leaned over and glanced at the various conspiracy theories on the web page, and shouted: "Dynasty! ”

"Why didn't you say it before?" Lin Chen asked Forensic Doctor Yu, "You know that this post exists, so I deliberately went to the citizen gene bank and checked Duan Wanshan's DNA, right?" ”

"Hey, forbid you to look at me like that!" Forensic Doctor Yu's eyes widened, "I'm obviously on Duan Wanshan's side to hide this post, okay, this is an obvious motive for killing, but if I really detect his DNA, can I not report it?" ”

The young man quickly pushed the door in, and when he saw the three people in the forensic office, especially the red-haired woman, he took a half step back: "Why don't you talk first?" ”

"." Torture Conglian said.

Wang Chao walked up to the forensic doctor, and when he saw the laptop on the table and the contents on the computer screen, he quickly rushed over and dragged the mouse to examine it carefully.

In the end, the young man said to them very apologetically: "I'm sorry boss Ah Chen, I was negligent, I didn't expect this to involve an online debate." ”

Xing Conglian didn't gag with him again, but just said: "Check IP." ”

Wang Dynasty nodded and quickly got to work. For a while, there was only the sound of keyboards and mice tapping rapidly in the office, and Lin Chen looked at the constantly changing computer screen, and had even worse conjectures in his heart.

"There it is." Wang Chao casually tore off a sticky note and wrote down a string of numbers.

"The specific address of the person who posted it." Torture Conglian said.

Wang Dynasty turned his head and continued to work, and after a while, his brows became more and more wrinkled: "The posting address is in Hongjing, very close to our home......"

Lin Chen raised his eyes suddenly.

Wang Chao stared at the screen and read: "No. 7 Cangjia Lane, obedient pet shop." ”

When he heard the three words of pet shop, the blood on Lin Chen's face instantly faded, and he coughed violently. Seeing this, the torturer Lian's heart tightened, and he hurriedly patted his back. He held Lin Chen's hand, only to feel that his palms were hot: "I'll send you back to the hospital first, and then go to the pet store." ”

"No, you don't." Lin Chen interrupted him, forcibly held back the discomfort in his lungs, and looked up at Forensic Doctor Yu.

"You mean, when I'm done with it, I have something private to talk about, so let me get off work, right?"

"I'm sorry." Lin Chen nodded.

Forensic Doctor Yu pointed to his laptop: "I'm telling you that you are not allowed to peek at the little yellow film inside." ”

"You can take it." Lin Chen said.

"You didn't say it sooner." The beautiful female forensic doctor glared at them, picked up her notebook and left, and as she approached the door, she turned back and looked at them worriedly.

The door closes.

"What's wrong?" The criminal servant asked.

Lin Chen took a deep breath: "That's Duanyang's post. ”

Lin Chen couldn't describe the feeling in his heart at all, maybe because of the fever again, he was chilling all over.

In fact, having experienced everything in the rainforest, he would never doubt Duanyang's feelings for Duan Wanshan, if he could, Duanyang would definitely be happy to die for Duan Wanshan.

So since Duanyang had no intention of framing Duan Wanshan, this matter had become by now - perhaps a long time ago, someone deliberately used Duanyang's design to frame Duan Wanshan.

And every step that Duanyang thought he took to avenge his teacher, every trace left on the Internet, may have been designed into the clutches of pushing Duan Wanshan into the abyss in the eyes of the initiators behind the scenes.

If Duan Wanshan hadn't died, all of this would have happened naturally, and Duanyang's self-righteous behavior would have harmed the teacher.

It's a pity that Duan Wanshan died......

Such an arrangement may be just a small malice, but it is as strong as ink and smells extremely fishy.

Lin Chen's mind was chaotic for a while, but no matter what, there were some things that had to be done: "We have to confirm two things. ”

Conglian nodded.

"First of all, in order to confirm the true purpose of the person who forged DNA evidence, we need to confirm with Duanyang whether anyone else other than us knows the news that Teacher Duan has died." Lin Chen paused, and then said, "Secondly, we must learn from Duanyang about the entire process of Stankang plagiarizing Mr. Duan's academic research results. If the murderer hadn't improvised to frame Duan Wanshan after seeing Duanyang's post, then this was a deliberate conspiracy, and in my opinion, the latter was more likely. ”

"Yes...... But are we going to tell Duanyang about this? The dynasty began with difficulty, "How uncomfortable he must be." ”

Lin Chen looked at the young man's tangled face and said, "He has the right to know." 166 Reading Network
