Profiler 2: Criminal Investigation Brigade

"Don't flatter me, you kid!"

Hou Xiyong smiled and said: "You do housework at home, who among us can do this stuff?!"

So without directly touching the vehicle, in the interior of the car, it sucked fiercely from front to back, left, right, up and down.The car looks okay on the outside, who knows that after such a toss, there are quite a lot of dust and paper scraps. What Jiao Yang is particularly interested in is that he really sucked out a few hairs.

A curly, yellowish long hair, which seemed to belong to the dead woman.There are also three short hairs, which are relatively thick and hard. They all look like men's hair, and one of them is white.

Yu Xiaoguang said, "Team Jiao really has you! Shall we guess which one belongs to the murderer?"

"Does that even need to be said?"

Hou Xiyong said: "Didn't it mean that this woman married an old man? It must be this white hair!"

Jiao Yang said: "Don't be preconceived, let's make bold assumptions and carefully verify."

Jiao Yang thanked the cleaning staff of the property, packed up the collected physical evidence, thought for a while and said, "Let's go, let's meet this professor!"

Jiao Yang took the initiative to ask for the case of only two deceased to the second team.

When they met Professor Fan Yiwen, he was in the mortuary of the Third People's Hospital to recognize him.

It may be that the internal comrades who notified him to come were more "humane" and had implicitly reminded him of the situation of the deceased at that time.Therefore, Professor Fan's expression is also quite exciting, with disheveled hair, red eyes, and a lingering streak of depression and wimp on his face.

Those present, except for the little nurse who led the way, were all men, so it was inevitable that they felt a little bit embarrassed.And Jiao Yang looked at this Professor Fan with a bit of vigilance.

The freezer was pulled out for more than a foot, seeing Fan Yiwen wanting to get closer, his body language was a little stiff, he stretched his right hand for a long time, and finally supported the outer edge of the freezer, after a long while he sighed and said: "Hey...it's me wife."

The scene looks a bit mournful, but there is no crying show.Jiao Yang stepped forward to show his ID and said, "Jiao Yang, Jiangcheng Criminal Investigation Serious Crime Brigade. Professor Fan, can we ask you something?"

Fan Yiwen pushed his glasses and said, "Unexpectedly, the law enforcement is really civilized now, tell me."

Jiao Yang said: "May I ask, do you know the gay man who had an accident with your wife?"

Fan Yiwen didn't answer, but asked, "Comrade police officer, do you have any cigarettes?"

Jiao Yang took out the Xuanhe door, Fan Yiwen looked at it, a little hesitant, "This smoke is too soft, is there anything else?"

"Hey you..."

Just as Hou Xiyong was about to get mad, Jiao Yang stopped him and looked at Yu Xiaoguang.

Yu Xiaoguang took out the long-mouthed Liqun he usually smoked, and gave it to Fan Yiwen, "Is this okay?"

Fan Yiwen took the cigarette and lighter from Yu Xiaoguang, lit it and took two puffs, and then said: "I've seen her a few times, and I know it's her friend. I forgot the exact name, and I can't tell them apart. She has many friends." It's also my fault, a moment of vanity... I didn't know until I got married that I couldn't control her."

Jiao Yang also lit a chimney and said, "Professor Fan, what have you been doing from 5:00 last night to this morning?"

Fan Yiwen said: "I finish class at 4:00 and return home at 5:00. Now it's the graduation season, so I start revising papers for the students. Around seven o'clock, I eat the leftovers in the refrigerator. Watched TV for a while, continued to revise the thesis around 8:00, got up at 10:30 to exercise for a while, took a shower, and went to bed around 11:00. Then I just got to school this morning, and I received a call from your colleague."

Jiao Yang asked: "You and Madam, how is your relationship?"

"Now I say yes, you can't believe it."

Fan Yiwen smiled bitterly and said: "Actually, apart from not liking her to go out and not caring much about the family, we can really do other things. We had a big fight last year and thought about divorce, but, I In this kind of situation, reading and teaching, making trouble in school is not good. She has no children, and my child is not around, and the two of them live together and have a companion. As long as she doesn't make trouble at home, I just turn a blind eye Just close your eyes."

Yu Xiaoguang couldn't help looking at Hou Xiyong, men are getting older, are they all so worthless?The wife is wearing a cuckold, which means that there is more than one, he knows it all, and he still doesn't get a divorce!This is still a university professor, why listen to this talk, just begging for perfection like a housewife with no income? !

Hou Xiyong coughed, and also looked at Yu Xiaoguang, intellectuals are too skinny, and they want to save face and suffer!

Jiao Yang patted Yu Xiaoguang's arm, signaling them not to make small moves here, and then asked: "Professor Fan, you know, your lover has had grudges with someone, or has a grudge, so you must kill her." ?"

Fan Yiwen was stunned and said, "What are you talking about, she was killed? Wasn't it carbon monoxide poisoning?!"

Jiao Yang stared at Fan Yiwen's expression and said, "It's not bad that it's carbon monoxide poisoning, but it can basically be regarded as murder. This is a situation. So I want you to think about it carefully, does your wife have any enemies?"

Fan Yiwen said hesitantly: "Probably not? Although the competition in their circle is quite fierce, I heard that it is nothing. The hot search for black people in the press release is not to the extent of saying they want to kill people, right? Let's talk about her. It's not very popular, and it can't block anyone's way. I think, um, no way. However, I'm not very familiar with people in her circle, and I don't know who she usually associates with. "

Jiao Yang thought for a while and asked, "Then let's change the angle. Do you have any enemies?"

"Me?!" Fan Yiwen was stunned again, "No. Police officer, do you think I have a personality that can offend people? I usually don't have any conflicts with my colleagues. I'm just a poor teacher, and I don't even think about it. You get promoted and get rich, and you get along well with your colleagues, so what kind of enemies can you have?!"

"Okay, thank you for your cooperation."

There is no evidence at present, Jiao Yang saw that he would not be able to ask anything for a while, so he saluted and closed the team first.

Early the next morning, Jiao Yang took Hou Xiyong to the university where Fan Yiwen worked, and asked the school leaders about his situation.

The school leaders confirmed Fan Yiwen's statement. Professor Fan is a good guy in the school and has a good relationship with his colleagues. He has the most contacts with Professor He from the Department of Chemistry and Professor Liu from the Faculty of Arts.

The love story between him and his wife was once a good story in school. Later, some rumors came out one after another. Professor Fan was not in school. He talked about his wife with his colleagues. He hadn’t seen him for more than a year. This actor The wife came to the school to find Professor Fan.

Jiao Yang returned to the police station, gathered the facts and evidence of the carbon monoxide poisoning case, called several people in the police station, and held a case discussion meeting.

"You guys don't mind, do you?"

Jiao Yang lit a cigarette and said, "Come on, let's all talk about it."

Hou Xiyong said: "I think it was Professor Fan who did it. He has the motive to kill, and he is the most qualified to install such a poisonous device. Such things as a good man are not convincing. They say that rabbits bite people when they are anxious. Many The murderers in the murder case are all gentle and gentle, and they can't prove anything at all."

Jiao Yang said: "But I think that when I talked with him yesterday, he was calmer and quite sincere."

Zhang Xianning said: "After all, he is a university professor. People who go to the podium all day should have a good psychological quality."

Jiao Yang looked at Lu Yuanli, "Professor Lu, please tell me."

Lu Yuanli said: "I don't know if the murderer is this professor, but I know that you must have a lot of work in this case. The social relations of the two deceased are very complicated. The people they interact with on a daily basis are from various schools and schools. To investigate interpersonal relationships, you have to investigate for a while."

Schadenfreude, isn't it?Is it so obvious? !Jiao Yang coughed and said, "Then Professor Lu can't just watch our jokes, can we do profile now?"

Lu Yuanli thought for a while and said, "Probably possible. Since the poisonous device was placed in the car of the deceased woman's husband, we can deduce that it is more likely that there is a problem with her interpersonal network, rather than of the male deceased.

Then, let's look at the method of killing. The highly poisonous gas is contained in a balloon and placed on the car. This is a very concealed and technical method of killing.

For example, with my country's strict control over such items, how did the murderer obtain them and store the poisonous gas?Will he accidentally cause the balloon to explode in the process of dressing up, causing danger?

However, none of them, the murderer successfully carried out the murder.From this, it can be inferred that the murderer is thoughtful, strong in action, highly educated, and probably has a laboratory environment.Moreover, the triggering element of this poisonous device is to put the seat flat, and the dead woman has sex with a person.Therefore, it can be concluded that the murderer was emotionally entangled with the female deceased, and the age of the Kochi crowd should be around 50 years old. "

Jiao Yang thought for a while and said, "That's still Professor Fan!"

Lu Yuanli said: "Then I think, whether it's him or not, you, Professor Fan, are always right. Of course, this top-ranking university in the country has a laboratory environment, so it must be able to obtain poisonous gas. After all, with the female deceased It is very difficult for social groups to obtain this poisonous gas and successfully commit crimes.

Moreover, we infer in reverse, if the murderer is not Professor Fan, and the use of this kind of directivity is very obvious, it will make people think that it is Professor Fan's method of killing, does it also mean that the murderer understands the relationship between Professor Fan and his wife, and Do you want Professor Fan to take the blame for yourself? "

"That's right!"

Jiao Yang stretched out his hand and snapped his fingers: "This is indeed a clear idea. In terms of probability, it is all related to the female deceased. It should be difficult to realize the two high-skilled groups who have no intersection with each other. The murderer Either it is Professor Fan, or it is a contact person who has a close relationship with him. The current situation is that the motive for the murder must be an emotional dispute. If it is Professor Fan, it is a cuckold issue. If it is someone else, the motive for the murder will be What?"
