Zhang Youfa brought the criminal police to Yu Lide's residence, but Yu Lide was not there at this time, and only his wife and a little boy less than five years old were left in the house.

The mother and son were a little embarrassed when they saw the police coming, and the little boy hid behind his mother and did not dare to come out.

Xiao Zhuo asked Yu Lide’s wife: “Have he been back?”

"I should have been back, but I didn't see him. When I woke up in the morning, I saw the notes he placed on the table."

"What note is it?"

Yu Lide's wife took out a cigarette box from the drawer of the main hall and handed it to Xiao Zhuo: "That's it. He said he was going to the county for a meeting. Police officer, what's wrong with Lide? Did he do what he did?"

At first, she just felt that she didn't know what was going on, but now she felt a little overwhelmed and became panicked.

Xiao Zhuo said nothing and looked down at the note.

The note only wrote a sentence with a red pen, "I went to the county for a meeting, from 3 days to 5 days." The signature was left with Yu Lide's name.

Zhang Youfa muttered, "What can you do? You have been on for so long? Why don't I know if you want to drive?"

Xiao Zhuo had a serious expression. He looked at the note carefully for a moment and then looked at Zhang Youfa: "Is there a phone number in the village?"

Zhang Youfa nodded: "Some are some, some are on the side of the brigade."

"Uncle Wang, follow him and call the township government if it will be opened."

Wang Youzhi followed Zhang Youfa and left. Su Li walked up to see the cigarette box in Xiao Zhuo's hand. After Xiao Zhuo saw it, he handed the cigarette box to her.

After Su Li took a closer look, she looked at the cigarette box for a long time and found that the cigarette box was not newly torn, and there were some stains and oil stains on it.

Some others were asking Yu Lide’s wife some questions, while others were observing near the main hall.

Su Li looked at Yu Lide's wife and asked, "Where did you find this note?"

"Just go to the table in the drawer. This is not the first time he has left notes, he has put them there."

Su Li looked at the long mahogany table she pointed at, with an old black and white TV set on it, and two thermoses. Next to the thermos was a tray containing several cups, and the note was placed on the corner of the tray.

"Is your husband left-handed?"

"Ah? Yes, yes."

Su Li looked near the tray for a long time, held the cigarette card in her hand and said to Xiao Zhuo: "It is Yu Lide's fault."

As Xiao Zhuo asked, she handed the note on the cigarette box: "There are a few subtle bloodstains on his name, and there are also on the table."

Xiao Zhuo also saw the red marks, but because the note was written in a red fountain pen, his first reaction was that it was the traces of red ink dripping and being wiped off.

At this time, I took the note and put it on my nose and smelled it for a moment, and confirmed that it was not red ink but blood. I leaned over to look at the table on the tray, and found a few more drops of strangeness.

Liu Ming and the staff from the Trace Department of the Branch immediately began to extract samples and evidence. At this moment, Wang Youzhi called back from the brigade.

"After verified, there are no meetings in the county!"

Gao Jinbao said excitedly: "It must be that he didn't run away. Not only did he lie, there was blood on the note!"

More than an hour later, Xiao Zhuo and others held a case analysis meeting at the county branch. They issued instructions to the police stations in various townships to control hospitals, checkpoints, and transportation hubs in various places. Once Yu Lide was discovered or the "cut-fingered man" was immediately

Control review.

It is already past four o'clock in the afternoon, and some people from the second team have had instant instant noodles in the branch conference room.

Fang Shunliang swallowed: "This case will be closed after Yu Lide is arrested!"

Xiao Zhuo: "It shouldn't work."

Fang Shunliang: "Why? Can you basically confirm that he is a broken finger man now? And if it weren't for him, then what would he run away?"

Xiao Zhuo: "There are still many doubts. Now I can only wait until I see him."

Gao Jinbao: "Suspicious? What else is there? He is left-handed, and the deceased was strangled by the murderer's neck with his left hand. Moreover, he had been caught by Zhang Erwei before and he had harassed the deceased. Now it seems that he is very suspicious!"

Xiao Zhuo said: "Justice Zhong called and said something about it. Judging from the autopsy situation, Yu Xianglan was strangled to death by her left hand, and the force was very strong. The victim lost his life without having time to resist. This shows that Yu Xianglan should be very familiar with the deceased.

, She had no precautions against the murderer."

Fang Shunliang: "Yes! Yu Xianglan and Yu Lide not only know each other, but also the uncle of the deceased!"

Su Li swallowed the face in her mouth: "But Yu Lide had harassed her. Normally, how could she not be careful of Yu Lide?"

Fang Shunliang: "This..."

Su Li: "Secondly, if the murderer is Yu Lide, then he will have sex with the deceased before being bitten and killed by killing people, or will he be bitten and killed by killing people before having sex?"

"If it is the former, judging by the traces on the scene, the deceased did not resist, so why did the deceased not resist? Was it voluntarily or was threatened?"

"If it is voluntary, it is different from the situation of the deceased reported by the villagers and the family of the deceased. If it is threatened, it has already been obeyed at the beginning. Why did you bite off his finger later?"

Xiao Zhuo continued: "If it is the latter, Yu Lide will strangle Yu Xianglan and then invade her after being bitten. The bitten left little finger will definitely leave blood on the deceased's throat, neck, bedside, bed sheet, etc., but

No blood was found during the autopsy, only the ground dripping blood."

Su Li: "There is another point. If it were the latter, everyone would be dead. Why didn't he retrieve his broken finger and leave such evidence to the police?"

Xiao Zhuo and Su Li said one by one, and the other people in the second team became more and more disappointed.

Fang Shunliang put the instant noodles on the table and sighed: "Oh, you two have been talking about it for a long time and there is no progress!"

Gao Jinbao also said: "I thought I could catch someone, but now it seems that it is not good."

Seeing that everyone had finished eating, Liu Ming got up and packed up, and wiped the table again.

Su Li looked at his silent and busy figure with appreciation, and sighed in her heart: Good man, good man, male mother is fragrant.

Wang Youzhi took a sip of water: "Although Xiao Su has been here for a short time, she is more useful than the old detectives in handling the case. We thought about it one step, and she and Team Xiao thought about it several steps."

Su Li smiled and said, "Uncle Wang, don't praise me anymore. I still have a lot to learn."

"Why are you a praising me? I really praise people."

Fang Shunliang followed Wang Youzhi and said, "This is indeed quite useful. If those people in the first team knew that you were so good at solving the case, would they regret driving you to the second team?"

Fang Shunliang's question was actually a bit embarrassing, and Wang Youzhi thought about turning around.

Su Li said indifferently: "I care what they think." Although his tone was plain, it just made you sound very arrogant.

Xiao Zhuo leaned on the back of the chair and laughed out loud in her tone. He had heard a little about Su Li's previous events these two days, but after listening to it, he became even more confused. The hearing and seeing were completely complete.

Not alone.

When Su Li heard his laughter, she turned her head strangely and looked at him. Xiao Zhuo waved his hand: "It's okay."

Seeing that she really didn't care about being kicked out, Wang Youzhi asked again: "How did you analyze the descriptions in the morning to make others think of Yu Lide? Or the criminal profile I mentioned before?"

Su Li nodded: "Yes!"

Wang Youzhi was even more curious: "What kind of profile are you? Why can you find someone? The previous case was the same, and the murderer was found in an instant."

Su Li thought for a while and said, "Imagine yourself as the murderer and speculate on the murderer's behavior."

Everyone: "????"

"Only when you take the role of the murderer can you figure out the reasons why the murderer does this, hatred, insecurity, fear and anger, all of which are in the murderer's behavior."

Fang Shunliang frowned: "Is this a profile?"

The other people looked at Su Li curiously when they heard this.

Su Li: "There is actually a great controversy in the actual application of criminal profiling. In foreign countries, the scope of work of criminal profiling writers is basically divided into two aspects: analyzing case facts and talking and investigation."

"Analyzing the case includes profiles of the suspect's portrait, geographical profile, correlation profile, confession analysis and psychological profile. The conversation investigation uses conversation skills to guide the suspect to actively or indirectly explain the crime."

"In fact, everyone has basically used these when investigating cases."

Gao Jinbao: "We all have?"

Su Li nodded: "In previous cases, everyone summarized and analyzed the scene of the murder case, and set the types of objects that might be engaged in such criminal acts, thereby describing the general characteristics of the suspect. This is the profile of the portrait."

"When judging whether the murderer is the same person through the similarity and differences between cases, the relevance profile is used."

"Geographical profile is to analyze the location and living environment of several victims, so as to judge the activity trajectory of the murderer."

"Explanation analysis and conversation investigation are very experienced, and also requires psychological assistance, analyzing the subject's language and attitude, so as to judge his psychological state of the case and whether he is lying, etc.."

Wang Youzhi: "I feel like I understand a little bit when I hear you say this, but why do you say this is very controversial?"

Su Li: "Because the main reliance on criminal psychology, many people think that psychology is very ethereal, so they are debating whether this is a conclusion based on scientific evidence, and because of the problems of ability and experience,

The accuracy is not very stable.”

Fang Shunliang: "So this is still a guess?"

Su Li shook her head: "In my opinion, the basis of criminal profile is scientific knowledge. Are analysis and statistical methods not scientific methods? Through these, based on psychological theories and accumulated experience, a method is formed to draw conclusions.

.It is an investigation method that can be selected according to the characteristics of the case and then according to the circumstances."

Xiao Zhuo's dark and deep eyes were quietly watching her talking with a smile. She was very smart and professional.

Gao Jinbao wailed: "Ah... so complicated! I'm so dizzy just by hearing about it. How did you learn it?"

Su Li: "Just...reading a book in class?"

Wang Youzhi sighed with emotion: "I am still old. If I am twenty years younger, I have to find a way to go to college." Then he gave Su Li a thumbs up: "Xiao Su, amazing!"

Seeing that he was really regretful, Su Li said, "Uncle Wang, if you want to learn, I can help find some books and materials."

Xiao Zhuo: "This is good. You can find more books in the office. I will reimburse you for the expenses. If some books are not easy to find, you can tell me that I will ask someone to ask."

Su Li looked at him: "Okay, but there is no need to be reimbursed. Some books were used when I was studying. I will buy them back when I encounter a suitable one."

Xiao Zhuo only laughed and didn't say anything, but Su Li knew what he meant. He always did this and always had his own principles in dealing with people.

The door of the conference room was knocked, and a police officer walked in and said, "In the morning, a man with broken fingers from the county hospital went to see the doctor. He showed the photo of Yu Lide, and he left after he prescribed penicillin and tetanus. The person has not been found yet.
