At one o'clock in the afternoon, the 1st District Police Station

"Knock knock." There was a knock on the door.

"Come in."

The door to Jiping's office opened.

"Flat, the victim's autopsy report is out." The officer who opened the door said.

"Okay, let's bring it in." Ji Ping looked at the documents in his hand, and Chen Yiyan was also looking at the documents on the side.

After the police officer went out, it didn't take long for someone to come from outside the office.

"Knock knock." The knock on the door rang again.

"Come in." Ji Ping spoke again, but Chen Yiyan and Ji Ping continued to look at the document without looking up.

"Yo, hello Advisor Chen, I heard that you are also here, so I want to send you in to see if you are really at the police station." The voice is from a woman.

Ji Ping raised his head, and the woman across the desk was wearing short sleeves with suspenders inside and a beige knitted jacket on the outside. Ji Ping had seen this woman, but the two were not very familiar.

Chen Yiyan raised his eyebrows, his head was facing down at forty-five degrees, and his right eye looked through the top of the spectacle lens, glancing at the other party who seemed to him to be a mosaic. Chen Yiyan didn't need to see clearly, he could hear who the owner of the voice was from the sound.

"Golden Forensics? You didn't wear a white coat today? Although Chen Yiyan couldn't see clearly, he could still distinguish the colors.

"Heh, I'm going to a meeting in a while, so I sent the autopsy report by the way." The person who brought the report to Ji Ping's office was the female forensic doctor Jin Yu.

"Thank you, Dr. Kim." Ji Ping stood up and stretched out his hand. Jin Yu looked at Ji Ping, stretched out the hand that had been put back in his pocket, and the two shook hands politely.

"I'll forget it." Chen Yiyan put down the document in his hand and looked at Jin Yu. "Did he kill?"

"It should be, it's all in the report, you can see for yourself, then I'll go to the meeting first." Jin Yu didn't care about Chen Yiyan's words, turned around and left the two of them behind, and walked out of the office.

"I've seen this golden forensic doctor a few times, but I didn't expect it to be so capable." Ji Ping muttered.

Chen Yiyan glanced at Ji Ping out of the corner of his eye, "How does it feel?" ”

"What's the feel?" Ji Ping asked.

Chen Yi stretched out his right hand and shook it in front of Ji Ping.

"Tsk, it's just a handshake, which one are you doing?"

Chen Yiyan shrugged his shoulders, "Sa is quite sassy, but he doesn't close the door." ”

Chen Yiyan got up and closed the office door.

The two began to work on the autopsy report that had just been sent by Dr. Kim.

The approximate content is: Name: Zhang Sen, Gender: Male, Age: 52 years old; Cause of death: Severe cerebral contusion caused by a blunt force blow to the lower part of the back of the head, and death from excessive blood loss. The wound on the lower part of the back of the head and the ball on the top of the bronze trophy match, and the murder weapon was determined to be a bronze trophy. As Dr. Jin said, she did just come to deliver the report, and she did not do the diagnostic examination of the cause of death of the body.

"Sure enough, that trophy is indeed a murder weapon, is it fingerprinted?" Chen Yiyan asked.

"Xiao Zhao informed me that the trophy had been scrubbed and no fingerprints were left."

"Then you said that the trophy that was found next to the corpse later was put back after it was disposed of?" Chen Yiyan felt a little strange.

"Yes, the killer may have been prepared." Ji Ping frowned. Chen Yiyan looked at Ji Ping's expression and didn't say anything.

"I'm going to hold a meeting on this case in a while, will you sit in on it?" Ji Ping put the autopsy report aside and prepared to send someone to inform Li Qinlan later.

"Okay, I'm fine anyway."

Three o'clock in the afternoon

"Okay guys, this case is likely to be a deliberate murder, Xiao Zhao, tell me about the clues we have now." Ji Ping pasted photos and documents of some related cases on the blackboard at the meeting place. There were a dozen or so criminal investigators sitting below.

The closest to Ji Ping was Xiao Zhao, Xiao Zhao took out his notes, "What is known now is that the cause of death of the deceased was due to the death of a copper trophy hitting the back of the head, the murder weapon has been determined, the time of death was yesterday at noon, the wife of the deceased heard a male voice arguing with the deceased upstairs, and when she went downstairs, she found that the victim had died, the deceased was a professor at Haishi University before her death, according to colleagues, the deceased was suspected of having received a call that made him behave abnormally, and now the technicians are cracking the deceased's mobile phone and computer, The letters found in the study had the fingerprints of five people, two of which belonged to Ping and Advisor Chen, one was the deceased himself, and two were not in the fingerprint bank. That's all the useful information we have for now. ”

"Okay." Ji Ping walked over to the blackboard. "Ren Shijie, you speed up the cracking of mobile phones and computers." Ren Shijie from the technical department nodded, "Understood." ”

"Xiao Zhao, you continue to go to the school to ask for clues. See if the students know if the victim has any holidays at school. ”

"Okay."

"The rest of the personnel, give me a careful look at the evidence obtained from the deceased's office and home, and don't let go of any useful clues."

"Understood, draw." The crowd said.

"Does anyone have any other ideas?" Ji Ping glanced at Chen Yiyan, who was leaning against the wall at the back.

"Is it possible that the other two fingerprints on the letter were the cooperation of the two of them." An executive in the back row said.

"This possibility is not ruled out. Jiang Sheng, are these ten or so letters all from the same person? ”

"Yes, Ping, the paper style of the fingerprint ten or so letters is the same, ordinary printing paper, the font and tone on it are the same, I am sure it was written by the same person." Jiang Sheng replied from the Evidence Division.

"Good. Now the outside media has begun to pay attention to this case, our last airport case was very good, it received a lot of attention, this homicide case should also be very energetic, do not let go of any subtle clues, and solve the case as soon as possible. Ji Ping nodded at Chen Yiyan as he spoke. Chen Yiyan understood that this was Ji Ping's thank you to him, but in fact, Chen Yiyan understood that he had actually done nothing at all in the airport case, and the fugitive was arrested, and the proof of his reasoning at that time was no longer needed.

"So be it, you guys go back and get back to work." Ji Ping said that the short meeting was over.

"What do you think?" Ji Ping asked as he picked up water next to the water dispenser.

"You said that the murderer was able to think of dealing with the murder weapon when the conflict escalated the murder, or that it was premeditated, but why did the letter leave fingerprints." Chen Yiyan expressed his doubts.

"No one is perfect, no matter how carefully planned the event is, there may be mistakes, maybe the murderer didn't pay attention at that time." Ji Ping took a sip of water.

"I have a way of finding the person who wrote these letters." Chen Yiyan suddenly spoke.

"Ahem, ahem." Ji Ping choked. Ji Ping wiped his mouth, "You say." ”

Chen Yiyan approached Ji Ping, "Isn't there a media paying attention to this matter now, I am 80% sure, the person who wrote the threatening letter should be from the school, you asked Xiao Zhao and them to find the media and say that we have made a major discovery, and the fingerprints of the murderer were found on the letter, and then the suspect can be determined by looking for data in the national database." ”

"The fingerprint bank only contains the fingerprints of people who have committed crimes, and the national fingerprint bank is still only a target. You mean, to convince them that there are fingerprints of income suspects in the fingerprint bank? Ji Ping looked at Chen Yiyan.

"No, you can know on the Internet that there are only fingerprints of people with criminal records in the fingerprint bank, but you know the human nature, when you are not clear about a certain thing, especially the things that upset you, you will only speculate, and when he speculates, it is when the road is wrong."

"You're saying he's going to come to the police station to steal letters?" Ji Ping was a little unconvinced.

"Not really, do you remember what we ask most often when we ask? Today we asked at the beginning. ”

Ji Ping recalled, his eyes slightly open, "You mean, abnormal performance." ”

"Yes, so you need to send more people to the school, so that the other party's heart will wonder if our police already have a suspect, I estimate that two days after the news comes out, he should react, unknown is the biggest enemy." Of course, this is the most feasible method that Chen Yiyan predicted, but if the other party is a ruthless personality disorder or a high-IQ murderer, this set may not be useful. "Okay, I'll go and inform Xiao Zhao now." Ji Ping finished drinking the water in the cup. "Are you going to stay at the police station for a while? I'll wait for me to drop you off at work, but I shouldn't be going back today. ”

"It's okay, you go about your business. I'll go to the evidence office again, and I'll go back myself later. ”

"Okay, then I'll inform Xiao Zhao and the media, I'll see you tomorrow."

"Okay." One of the two walked towards Xiao Zhao's desk, and the other walked towards the place where the evidence was stored.

"Hello Officer Jiang, can I take a look at those threatening letters again?"

Jiang Sheng, who was checking the list, raised his head and helped his glasses, "Oh, it's Consultant Chen, yes, I'll help you take it out." ”

"Okay."

Jiang Sheng took out a box from the evidence display case, "The relevant things are here, you can take your time, I will get off work in two hours, you can give it to me before then." ”

"Okay."

Chen Yiyan took the box and walked to the empty seat on the side and took out more than a dozen printed letters.

The font of this print should be the font size 3 font of the main font, which is the same as the font requirements of the college paper, if it is not a coincidence, it should be someone in the school. The paper is ordinary printing paper, this kind of paper is easy to get dirty and discolored, and this threat letter will not go to be saved, so it should be that these dozen or so letters are recent. Judging from the description of this textual language, there is not a single word I from beginning to end, which may indicate that the threat party did not threaten Zhang Sen for their own interests, and it is more likely that Zhang Sen's secret was discovered, but in this case, it will not be murderous, and if the conflict escalates, it is impossible to deal with the murder weapon in that situation. Chen Yiyan pondered.

Time passed quickly, and when Chen Yiyan was looking through other relevant evidence, it was almost time to get off work. Chen Yiyan glanced at the clock hanging on the wall and returned the evidence box to the evidence vault. Then I went out and prepared to go back to the office.

Walking on the road, Chen Yiyan took out his mobile phone, the latest news of his friends is still Yu Yuqian's, and Chen Yiyan has not many friends.

'The unknown is the worst enemy, am I guessing now?' Or maybe I thought about it but didn't want to accept it? Chen Yiyan smiled, but the taste was slightly bitter. "It's still easy to handle the case, so you don't have to think about it so much."

ps Obviously, you thought more about it when you were handling the case, but there was less emotional erosion, and you couldn't analyze the scenery and location in this photo to deduce Yu Yuqian's hotel address?

Chen Yiyan broke through the dimensional wall: "You don't want me?" But everyone has their own life, what right and right do I have to interfere with others? Whatever you want, it's your love story and it's not mine anyway.
