Criminal Psychology

The punishment was loosened from the chopsticks, and the newly raised chicken leg slammed down. The soup splashed, the dynasty was stunned, and Zheng Xiaoming seemed to be aware of the abnormality and looked at them in confusion.

Lin Chen felt a little uncomfortable, but still touched Zheng Xiaoming's head with relief, stood up and asked the dynasty, "We may not be able to come back in one and a half. You wait for Xiaoming's parents to pick him up." He finished, Zhang Xiaoming Still holding his hand.

Lin Chen touched the little fat man's face and relieved, "Your mother has my phone. If you want to see me, you can ask her to call me."

Lin Chen said so, and Xun Conglian left the cafeteria and went to the forensic department together.

Along the way, they walked side by side, and the police officers who came to send the inspection report were very happy and did not stop saying, "Captain, this is a major discovery. The forensic doctor suspects that the suspect may have accidentally cut his hand during the murder, so Leave your blood on it, and you can still detect DNA samples after wiping. "

"Um." Xun Conglian didn't respond, but said lightly.

The police officer came back with a spirit: "The reason why he wanted to release the weapon was also because his blood was stained on it, so the weapon must be destroyed?"

Xing Cong didn't even talk, and the police officer said to himself: "Speaking of which, Duan Wanshan is also very strange. I just took a look at his profile. He was a professor of medical science at the university. It seems that he has resigned and left the country, and there is no record of it anymore. His nationality is still in our country, but why did he suddenly enter the country and kill Dr. Stancom, I will wait for the entry and exit to check his entry records. "

Xun never talked, Lin Chen walked behind.

It was dark outside the window and the air conditioner in the corridor was so cold that he couldn't help but cough slightly.

Probably seeing his face look ugly, Xun Conglian asked: "Does the wound hurt?"

"No," Lin Chen said.

"I'll take you back to the hospital first, and I'll let you know the results as soon as I find out." Xing Conglian was worried. If there weren't other police officers around, Xing Lianlian would stop and hug him. .

Lin Chen knew that he was not in a good condition, but insisted: "I have stayed for so long. It is not bad now. Go to the forensics department first."

Xing Lian stretched his hands on his forehead and frowned. "A little hot."

"I think it's okay. Just after eating, my temperature is normal."

"Isn't your x-ray filmed yet?" Xun Conglian asked.

"That's a shortfall," Lin Chen said.

"The next time I go back, I'm afraid you have a lung infection." Xun Conglian said solemnly.

Lin Chen nodded.

The policeman who led the way turned back again: "Advisor Lin, you have to be hospitalized if you are not well. Now the case has also made breakthroughs. You don't have to keep your eyes on it. Take a good rest. Your body is the capital of revolution . "

Lin Chen shook her head, wondering how to answer.

...

There are still more than half of the staff in the forensic department, and the room is brightly lit.

Because the results have just come out, and a DNA sample matching object has been found, many people have learned the news and are in a good mood.

Xing Conglian greeted the police officers inside, took a chair and sat down, asking, "Where did you go?"

Police officer of the Forensics Section replied: "The DNA results from the forensic doctor came out. We are now going to compare the fingerprints on Stancon's notebook and the fingerprints extracted from the tape with those of the suspect Duan Wanshan ..."

"Isn't it possible to find out who the fingerprint was on the notebook from the beginning, since we don't have the fingerprint of Duan Wanshan in our library, where can we find the comparison target?" Xun Conglian asked.

"We have just called Duan Wanshan's former work unit, Yongchuan Medical College, and asked them if they have relevant records."

"For so many years, can the fingerprint records of former employees be kept in Yongchuan Medical College?"

"In case, captain," the policeman grinned.

Suddenly, the facsimile machine of the Forensics Division rang.

Someone picked up the contents of the fax and shouted, "Comrade Xiao Zhang, your fingerprint is here!"

Lin Chen and Xun Lian looked at each other.

Officer Xiao Zhang ran to the fax machine with excitement, took a glance at the fax content, turned his head and said, "Captain, Yongshan Medical College Duan Wanshan once led his lab. His fingerprint records are still kept, only his thumb, But it's enough. "During the conversation, Xiao Zhang opened his mailbox and an email lay there quietly.

Officer Xiao Zhang quickly operated the computer and compared the fingerprints in the email with the two sets of fingerprints found on the laptop and plastic bag.

Lin Chen bowed his head, somehow, his heart beat a little faster.

The results came out quickly, the printer creaked, and Officer Zhang pulled out the paper and walked towards them.

"How?" Xun Conglian asked.

Xiao Zhang showed a smile on his face, he grinned, and was pleased to report: "Captain, the 14 characteristic points coincide, and we can conclude that the fingerprints found on the deceased's notebook and the bag containing the murder weapon belong to Duan Wanshan himself!"

Lin Chen suddenly looked up, his heart shook.

Duan Wanshan has died in the Dana rainforest. This is what he saw with his own eyes. Now, the other person's DNA samples and fingerprints appear again. What is going on?

Forensic Section whispered, as if happy to identify the suspect.

"Captain, what shall we do next?" Officer Zhang asked.

Xing Conglian rarely had such a moment when he was asked to be dumb, and his eyes seemed to be looking forward to Xing Lian's order to search for the suspect: "Wait a minute, I have a few questions." Xing Lianlian Get the idea and start talking.

"The first question is why two DNA samples were detected on the weapon." He asked.

"The second DNA sample was found at the handle." The other responded, "So we suspect that the suspect accidentally cut his hand when he committed the murder ..."

"I know this." Xun Conglian interrupted the other party. "It is definitely a DNA sample from the blood, isn't it any other cell tissue?"

"Yes." The police officer who came to send the report nodded.

Xing Lian turned his head and asked the other party: "The second question, why do we have a DNA sample of Wanshan Duan and quickly get a comparison result, what has he done before?"

"It doesn't seem ..." The other responded, "I'll check it later."

Lin Chen frowned. This is really strange. It is important to know that the citizens' DNA samples belong to individuals * and the testing costs are high. Unless a crime or some special circumstances, it is impossible to be recorded. Thinking about the possibility of Duan Wanshan's DNA samples appearing in the citizen's gene bank, he asked: "Or what kind of victim?"

"It's not clear. I'll ask right now."

"no need!"

There was a light noise at the door, Lin Chen looked at it, and saw the dynasty holding a mobile phone standing at the door.

After the handsome man said the words "no more", he bent over and ran over, reporting to him: "Brother Ahchen, Father Xiaoming has taken my brother away."

"Thank you," Lin Chen said.

"Ah Ah Chen, you're welcome again, but that's my brother." Wang Chaobian said, took the inspection report, took out his mobile phone, and then quickly answered the question from Xing Conglian, "Teacher Duan's DNA sample appeared in citizens The reason for the gene bank is ... "He suddenly looked up," is it because of the mch plan? "

"Speak people." Xun Lian said.

"I don't know too much." The dynasty was rare and modest. He licked his fingers, began to quickly tap on the screen of the mobile phone, and then said, "mhc, the major histocompatibility complex, immune to humans. The system functions are closely related. Through accurate sequence analysis and genotyping of the mhc region, the mhc plan fully displays the mutation sites of the mhc region and the polymorphism map of the hla gene in the Chinese population. Lays a solid foundation for correlation studies ... "

Xun Lian even interrupted him: "That is to say, the reason why the DNA sample of Duan Wanshan appeared in the gene bank has nothing to do with any case, just because of the medical plan."

"It should be so." The dynasty nodded, still looking at the messages on the mobile phone, "Ms. Duan seemed to be the first medical scientist to respond to the plan. Some people opposed the plan at the time, which meant that the genetic information was a citizen *, the government Doing a large-scale disease investigation is a violation of citizens *, so Teacher Duan took the lead in participating in this program. "

"Like the old section would do." Xing Conglian said.

The police officer who came to deliver the materials before, and then stood next to them, seemed to guess something, and suddenly said, "Captain, do you know?"

Xing Lianlian calmly said: "I know, I was ... a good friend."

"Oh ... it's your friend." The police officer prolonged his tone, a little embarrassed, "So ... then do we need to ask your friend to assist in the investigation, there are actually many possibilities for him A blood sample will appear on this knife, such as he accidentally got it on and gave it to someone ... "He began to try to explain some other reasons.

"No, please," Xun Conglian said.

"For ... why?"

"Because I know that he has been abroad and has not returned to China for many, many years." Xun Conglian said faintly, but did not mention the news that Duan Wanshan had died.

Lin Chen lowered his eyes.

The police officers around them took a breath of breath: "It's ... this is impossible, it's blood and fingerprints, and the evidence is relatively good."

"Is there any recent entry record for Duan Wanshan?" Xing Conglian asked back.

The dynasty had already found the computer of the Taiwan Identification Bureau, logged in to the immigration management center, and then entered Duan Wanshan's name for inquiries.

He angled the computer and said to everyone, "Come and see."

Xing Cong and Lin Chen were useless, but many people surrounded him.

"Duan Wanshan's last entry was on August 10, 2007 ..." Someone said according to the information on the screen, "and entered the country on September 1 of the same year, and then there were no entry records ..."

"It's weird," someone said, touching his nose. "Is there a mistake in immigration control? Shouldn't it ..."

"This only shows that Duan Wanshan did not enter the country through formal channels, and he may sneak in." Someone said.

"But if Duan Wanshan has been abroad, how did he resent Stan Kang and why did he kill people?" Finally, someone asked.
