Criminal Psychology

Speculations arose, Lin Chen's punishment never kept silent.

Yeah, all the physical evidence lacks witnesses. Lin Chen doesn't even suspect that there may be any witnesses who have witnessed Duan Wanshan in two days.

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

Lin Chen couldn't help but cough. This enemy feels really bad in the dark, and the conspiracy actually surrounds the dead Duan Wanshan. It feels even more unacceptable.

Xing Lian cast a concerned look. Lin Chen looked at the other person's gloomy eyes under the incandescent lamp and said, "Let's go to the forensic room?"

"it is good."

...

The forensic doctor of Hongjing Police Station was a lady, burning a wave of bright red waves.

When they arrived at the door, the forensic doctor was holding milk tea and carrying a bag ready for work. The sentence passed and held the door, pushing people back into the office.

"Hey, I like girls, you stay away from me," Yu said.

"It's all right, I like men." Xun Conglian said.

Lin Chen pushed in the door and saw that Xun Congzheng pressed the forensic doctor into a chair, snatched the pearl milk tea from the opponent, and threw it into the trash bin accurately.

"Xian Conglian your sister!"

"Why rush to get off work?" Xun Conglian asked sharply.

"I rely on it, it's seven o'clock in the evening. I've been working overtime for two hours, okay."

"Sit down for a while."

Xing Conglian said dragging a chair, Lin Chen sat down and greeted the beautiful lady in front of her: "Yu forensic doctor."

"Advisor Lin."

"What are the ways to fake the DNA evidence?" Lin Chen asked straightforwardly.

"Advisor Lin!"

Yu Forensic face sank: "It doesn't matter if I don't let me off work, why suddenly came to ask such strange questions!"

Lin Chen said: "We suspect that the DNA sample belonging to the suspect Duan Wanshan on the murder weapon of Stankang was forged."

For a long time, Yu Forensic Doctor did not speak. The smell of formalin floated in the air, as well as the smell of fresh gel water among forensic red hair.

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

Lin Chen replied: "Duan Wanshan has been abroad. Without entry records, it is impossible to suddenly appear in Hongjing to kill."

"If you engage in criminal investigation, you should be able to find out hundreds of methods and possibilities for his return." Yu Forensic Doctor said.

Lin Chen said simply: "Impossible."

"That line, as you said, even if someone framed him and stole his blood sample and stuck it on the knife handle." Yu Forensic Doctor changed his leg and tilted his leg.

"It's impossible."

"Why?" The female forensic surged forward.

"I can't tell you for now."

"You are trying to force me to die." Yu Forensic Doctor leaned back on the back of the chair, and I checked it out, and you look like me.

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

The red-haired female forensic expression was stunned, and Liu Mei raised her head high, "I see, you want me to tell you, is there any way to fake DNA evidence?"

"Yes."

"Have you ever wondered how the pressure on prosecutors in the future court debates if there is a typical case of fake DNA evidence? Numerous defense lawyers will use this to attack the reliability of judicial identification." Yu Forensic asked.

"But this is an unavoidable problem. In this case, I am pretty sure that there is evidence fraud." Lin Chen insisted.

Finally, Yu Forensic Doctor sighed long and said, "It's actually very simple."

"How easy?"

"Suppose, I can get your DNA samples, not too much, even a single strand of your hair is fine. A lot of DNA is amplified by PCR technology, and then a tube of old blood is drawn, separated by a centrifuge, Make white blood cells containing DNA, and then add your DNA to the blood of the old sentence ... "

Lin Chen looked directly at the forensic doctor: "The tube of blood has been forensic identified and belongs to me, not to him."

The beautiful female forensic nodded solemnly: "This is just the simplest method, and it can be done by undergraduates in biology."

"I see." Lin Chen stood up to pay tribute, "Thank you."

"Do you question my appraisal results and say thank you and just want to run?"

Lin Chen lowered his eyes and said to Yu Forensic Doctor, "In fact, I have one more thing to know."

"Your eyes are particularly disturbing." Yu Forensic doctor looked at him with his arms folded.

"I suddenly realized that you didn't tell us something clearly," Lin Chen said indifferently. "Although I don't know the specific division of the gene bank, you can find that DNA that is a section of Wanshan so quickly, still makes me Surprised. "

"I rely, you are doubting me!"

"I'm solving the answer."

Yu Forensic stared at him for three seconds, took a long breath, pulled the head rope from his left wrist and tied his hair high, pulled out his notebook from his backpack, and opened it openly: "Do you know Dingyuan Forum? "

Lin Chen frowned: "Medical Forum?"

"It's the largest medical-related forum in China." Yu Forensic turned on the computer. "I'm an administrator of a sub-forum inside, so basically I go up to handle station-related matters every day." Yu Forensic paused, "I explained this to tell you , I'm not picking things. "

Lin Chen nodded.

"It's not the style of painting if I really pick something." Yu Forensic Doctor opened the forum, typed the keyword "plagiarism Stancom" in the search box, and then pressed the Enter key. "About a month ago, someone posted After posting, it was suggested that Stancom copied the research results of Duan Wanshan, because the two were academic bulls, and the discussion was very lively. However, the landlord did not provide any key evidence and left it alone. "

Lin Chen's heart stunned, and finally realized where the uneasiness came from. If the other person designed to frame Duan Wanshan, it would definitely make a complete chain of evidence, in addition to the physical evidence, including the motive for killing, and now that this post exists, the motive for killing is coming out.

Duan Wanshan was plagiarized by Stankang because of his research results. He was resentful and returned to China to murder Stankang.

"After Stan Kang's death, this post was uplifted again by a caring person." Yu Forensic said meaningfully, "You know ..."

Xun looked at various conspiracy theories on the webpage and shouted, "Dynasty!"

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

"Ah, you are forbidden to look at me with this look!" Yu Forensic Doctor Xing Muyuan opened, "I obviously stand on Duan Wanshan's side to hide this post. Is this an obvious motive for killing, but it is true detection Can I not report his DNA? "

The young man quickly pushed in the door and saw the three men in the forensic room, especially the red-haired woman, taking a step back: "Can you talk first?"

"Come over," said Xun Lianlian.

The dynasty stepped forward in front of the forensic doctor. When he saw the contents of the laptop on the table and the computer screen, he rushed over and dragged the mouse to examine it carefully.

In the end, the young man said to them with regret: "I'm sorry, Boss Chen, I was negligent, and I didn't expect that this would involve cyber debate."

Xing Lian never slapped him again, but said, "Check the IP."

The dynasty nodded and began to work quickly. For a time, there were only rapid keyboard and mouse sounds in the office. Lin Chen looked at the ever-changing computer screen and had a worse guess in his mind.

"Here it is." The dynasty ripped off a sticky note and wrote down a string of numbers.

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

The dynasty turned his head and continued to work. After a while, his brows frowned and tightened: "The posting address is in Hongjing, very close to our house ..."

Lin Chen suddenly raised his eyes.

The dynasty stared at the screen and said: "Cangjia Lane 7, obedient pet shop."

When he heard the words in the pet shop, Lin Chen's face faded instantly and he coughed violently. When Xun Lian saw this, his heart tightened and he patted his back. He held Lin Chen's hand, only feeling that his palm was hot: "I'll take you back to the hospital before going to the pet shop."

"No." Lin Chen interrupted him, holding back his lung discomfort, and looked up at the forensic doctor.

"You mean after running out I have private things to say so let me get off work, right?"

"Sorry." Lin Chen nodded.

Yu Forensic pointed to his laptop: "Tell you the yellow **** inside is not allowed to peek."

"You can take it away," Lin Chen said.

"You didn't say it earlier." The beautiful female forensic stared at them, picked up the notebook, and left. As she approached the door, she turned back and glanced at them anxiously.

The doors are closed.

"What happened?" Xun Conglian asked.

Lin Chen took a deep breath: "That's Duan Yangfa's post."

Lin Chen couldn't describe the feeling in his heart now, maybe because he had a fever again, he was cold all over.

In fact, after going through everything in the rain forest, he would never doubt Duan Yang's feelings for Duan Wanshan. If he could, Duanyang would be happy to die for Duan Wanshan.

Well, since Duanyang unintentionally framed Duan Wanshan, this matter has become so far-perhaps long ago, someone was deliberately using Duanyang's design to frame Duan Wanshan.

Every step of Duan Yang's self-righteousness for the teacher and every trace left on the Internet may have been designed to push Duan Wanshan into the palm of the abyss in the eyes of the creator behind the scenes.

If Duan Wanshan wasn't dead, all this would happen logically, and Duan Yang thought that the kind behavior would hurt the teacher.

Unfortunately, Duan Wanshan died ...

This arrangement may be just a little malicious, but it is also intense and stinky.

Lin Chen's mind was extremely chaotic for a while, but no matter what, some things had to be done: "We need to confirm two things."

Xun Lian nodded.

"First of all, in order to confirm the true purpose of the person who forged the DNA evidence, we need to confirm to Duanyang whether anyone else knows that Duan Duan has died." Lin Chen paused and said, "Secondly, We must understand from Duanyang that Stankang copied the entire academic research results of Mr. Duan. If the murderer did not intentionally frame Duan Wanshan after seeing Duanyang ’s post, then this is a deliberate conspiracy, in my opinion, More likely. "

"But ... but do we have to tell Duanyang about this?" The dynasty began hard, "How uncomfortable he is."

Lin Chen looked at the tangled face of the young man and said, "He has the right to know."
