Chen Shi asked: "What is your relationship with Kong Tingting?"
"College classmates, friends."
"More than that, right?"
"Xiao Wang must have said it? Yes, I chased her, but she never promised me. In fact, I haven't contacted her for a long time. I heard her death, I just felt a little sudden."
Chen Shi had been observing his words and expressions, and Han Le's eyes flickered, as if he was hiding something.
He decided to throw a bomb and said, "Do you know that before she died, Kong Tingting thought she had AIDS and madly slept with a strange man?"
"What!?" Han Le was shocked, "Impossible, she is not that kind of casual girl."
"You don't need to assert this matter, it's a fact."
Han Le was stunned for a long time without speaking, and then said: "Well, I know people will change. Maybe she is no longer the innocent girl who used to recite words under the willow tree in the early morning."
"Do you know who has a knot with her?"
"How could I know that, having said that we haven't contacted for a long time, I can't catch a tree and hang it. Actually, I have a girlfriend a long time ago. Hey, that's it." He pointed to the cashier with his chin. , There stood a girl with short hair and freckles.
Chen Shi took out his mobile phone and prepared to exchange contact information, "What's the situation, can you contact us in time?"
"must!"
"Then don't bother."
Lin Dongxue frequently gestured to Chen Shi with his eyes, and Chen Shi turned a blind eye. After leaving the supermarket, Lin Dongxue said, "Why don't you ask for alibi."
"If you talk too much, you will lose it. Don't ask such direct questions all at once."
"Do you think he told the truth?"
"I feel something is concealed... Miss Lin, have you ever had a spare tire?"
Lin Dongxue's eyes widened, "Why do you ask? Girls have vanity and like the feeling of starring over the moon, but I never do that kind of thing."
Xu Xiaodong said: "I used to be a spare tire."
"Talk about your feelings."
"I liked a girl when I was in middle school, and I asked me out to play, but she never wanted to go with me in front of her classmates. Later, she found out that she had a boyfriend. She was really sad."
"Will you want to kill her?" Lin Dongxue asked curiously.
"No, it's just sad... Of course, I hate her a bit."
"The mood of the spare tire is really delicate, this Han Le can observe it." Chen Shi said.
Chen Shi did not leave directly, but sneaked into the staff locker room, and an older sister walked in and said, "What are you doing?"
Chen Shi gave Lin Dongxue a wink, and Lin Dongxue took out his ID, "We are the police, we are investigating a..."
"Theft case! One of your employees lost an important item. It was only reported yesterday."
The eldest sister didn't see that Lin Dongxue's ID was a criminal police officer. She believed it was true and said, "Why don't you find a manager?"
"When it comes to privacy, the reporter doesn't want to make any noise, can I trouble you..." Chen Shi pointed to the cabinet.
"Yes, it is necessary to cooperate with the police."
The eldest sister went to fetch the keys. Chen Shi asked her to open several cabinets in turn, pretending to be looking for something. Finally, she asked to open the locker with Han Le's name, which contained Han Le's clothes. Chen Shi had a sharp eye. Seeing a piece of hair, I took it off while the eldest sister was not paying attention.
There was also a book under the clothes. It was a detective novel called "Night Eyes". The author Xin Bai and Chen Shi said, "Which author wrote it last time?"
"Comrade Officer, have you found it?"
"No, no, let's look at other cabinets."
Pretending to read all the cabinets, Chen Shi thanked the eldest sister and left.
The three discussed where to investigate the case next. In the chat group of the task force, Peng Sijue said that he had made some progress. In addition, Lin Qiupu said that a friend of the deceased wanted to report some of the situation. He was very close to them and asked them to run.
Chen Shi said: "Then let's split the troops into two for the time being. I'll go back to Lao Peng, and you can find out the situation."
Lin Dongxue ridiculed: "Captain Peng will always be the first."
Back in the bureau, Chen Shi went straight to the technical squadron. The room was so cold that people were freezing to death. The police officers were stomping their feet to keep warm, while Peng Sijue sat in front of the microscope and looked inwardly, unaffected.
"What's the matter? The technical squadron changed to the Tomb faction?" Chen Shi joked.
A police officer said: "The captain is doing an experiment on food rotting in the refrigerator."
There was an old refrigerator in the room, and Chen Shi smiled and said, "Really dedicated!"
Peng Sijue said without looking back: "The normal temperature is now 5 degrees. It may take a lot of time for the ice cream in the refrigerator to melt like that... In addition, I also looked at the experimental data of the University of Tennessee, at a room temperature of 30 degrees. , The decay of the corpse will accelerate for five hours."
"The Corpse Farm?"
"Yes!"
Three universities in the United States jointly built a corpse farm, which contains various corpses, blisters, buried, sealed, and peat tanned corpses, to collect data on the decay of the corpses under different conditions for the purpose of solving crimes. .
Peng Sijue said: "Were there any power outages on the night of the incident, there would be a five-hour error in the estimation of the time of death, but how to determine whether the power outage occurred that night?"
"On the way I came back, there was a guess that the murderer was the deceased who was killed at 3 o’clock in the afternoon, and then went outside to pull the switch off, and then quietly came back the next morning to turn on the switch. From the perspective of the forensic doctor, the air conditioner was always on in the room. , So I guessed that the time of death was shortened. It was judged that the murder occurred at 7 o'clock in the evening. In fact, the room has always been at room temperature... This is a reverse thinking. If the murderer really did it intentionally, he must be very smart."
"It's too smart to induce the idea of a forensic doctor. Why would he do this?"
"Alibi, when the police found him, he could calmly say that I had alibi at 7 o'clock that night."
Peng Sijue pondered for a moment, and said, "There is another possibility. The power outage happened before. The food in the refrigerator has already gone bad. The murder happened at 7 o'clock that night... Don't forget, that man at 7 o'clock. I also received a call from the deceased."
"What I said was a conjecture, a bold hypothesis, and careful proof."
"I think you have considered the murderer too complicated."
"No, when a person wants to get rid of sin, he will show a higher level of wisdom than usual. This is called wit."
"Just discussing here, there is no result, it is better to go to the scene and take a look."
Chen Shi immediately agreed and said, "Wait, I have something to give you." He gave Han Le's hair sample to Peng Sijue, "Compare it with the hair found on the deceased."
Peng Sijue handed this over to his subordinates. A police officer said: "Captain, the result of the dander sample has come out. The DNA matches exactly."
Chen Shi was taken aback and asked what was going on. Peng Sijue said, "It seems that there is no need to go there. The suspect has been identified."
