Yin Feng has been with her for several days, and he sees her all the time, which makes him feel extremely satisfied. It's like a child who wants to eat candy and eats a big jar in one go, so it's not so sticky, and then eat hard. The more important reason is that he feels that he stinks too much! Eating and sleeping with a group of criminal policemen, not taking a bath for a few days, seeing that they are all fine, even You Mingxu seems to be accustomed to it.

Yin Feng can try not to think of her stink, but he can't bear to stink himself, then You Mingxu will hate him! He had to be fresh and beautiful in front of her all the time. So he retired today, and asked Chen Feng to prepare a large bathtub full of milk petals, and be sure to wash himself before You Mingxu went home. In addition, when she comes home, prepare a pot of the same pot for her. Two people are as fragrant as they are entering and exiting.

And You Mingxu plunged into the case in the next time.

The results of the on-site investigation of Xu Jiayuan's case came out quickly: it was confirmed that he was killed at around 11 o'clock that night, and the murder weapon was a watermelon knife, but the size was different from Xie Huifang's case. In addition to Xu Jiayuan's footprints, a 38-yard footprint was also left at the scene. This is not in line with the deceased's card friends and roommates.

——

You Mingxu was busy until the next night, and then dragged his tired body back home.

The moment I pushed the door open, I thought I would see someone sitting on the sofa waiting stupidly. But when she saw that the room was dark, there was no sound at all, and the doors of both bedrooms were open, and she was still stunned.

Where did the wild go?

You Mingxu thought a little unhappily. She didn't bother to look for it, so she went back to the house and took a shower, changed into pajamas, and lay on the bed for a while, but the guy hadn't come home yet.

She sat up and called him. The bell rang and it was in the next room.

If you don't bring your phone, you haven't gone far. You Mingxu frowned and thought about it, and suddenly remembered that when he went upstairs just now, the light next door seemed to be still on.

The house next door was not rented by Chen Feng a long time ago? I still have a key in the house.

Picking up the key and standing in the dark stairwell between the two households, You Mingxu thought for no reason: When did I get used to living with that little heel and adapt to the role of mother?

She knocked on the door first, but she didn't answer, took out the key to open the door, the light in the living room was not on, and the light shone out from the door in the front room. You Mingxu hasn't been to this house yet, so he looked at it casually, and felt that it had obviously been renovated, exquisite and simple, with very little furniture, probably because it was convenient for Chen Feng to take a group of people to serve the boss.

When he arrived at the door of the room, the door was open, and as soon as You Mingxu wanted to knock on the door, the whole person froze.

It's not that she can't stand it, it's really the scene in front of her, which is a little shocking.

It was almost an empty room, with huge blackboards hanging on all four walls. At this time, each blackboard was densely filled with words. Yin Feng sat on a high stool with his back to her. Still sitting like that, with his legs spread out, his hands pressed on the stool between his legs, like a lonely teenager.

You Mingxu didn't greet him first, but looked at the words on the blackboard in front of him first.

In the first row, there is a big question: What if I am the murderer?

The word, like his signature she had seen before, was flying and majestic, and the bones were beautiful. At first glance, it looks like a printed copybook. You Mingxu really couldn't connect the thing in front of him with the person with such a handwriting.

Suddenly, the picture I had seen came back to my mind: a man in a gray T-shirt, sunglasses, and a mustache around his lips, walking out of the car with a grim face.

But You Mingxu's interest in the case is undoubtedly greater than Yin Feng's fine score. She immediately looked down. The following is the process of the murderer in Xie Huifang's case:

1. Prepare tools;

2. Follow-up observation;

3. Knock on the door to enter;

4. Control children;

5. Threatening the mother;

6. Killing the mother;

7. Killing children;

8. Accumulation of corpses;

9. Change out of bloody clothes;

10. Leave the scene;

*Note: On the face of it, I have no direct connection to the deceased, no hatred.

So, are the great writers working backwards? Think of yourself as a murderer first, and then push yourself back to what you should do?

In addition, many details and clues of the case were listed, such as "size 39 shoes" and "foot gloves"; "The deceased had a strong personality and had quarrels with colleagues"; "Discipline children strictly"; "Notice of Payment for Summer Camp"; "Cold Medicine for Children"; "Go home every day for a lunch break"; "I had a big fight with my nephew the night before" and so on.

even drew the daily activity route and community map of the deceased before his death; Nephew Li Biran's Internet café distribution map......

Densely packed with a full page. In fact, this information has been sorted out by You Mingxu and them, but it is basically a division of labor and cooperation, and everyone is responsible for a line. Unlike this person, who piles almost all the information together, and there is no logic in the front and back, it seems that he thinks of something and writes it up.

At this time, Yin Feng turned around and saw her. His eyes were still empty and cold, as if he was in a daze, but suddenly he seemed to be lit up, jumped down from the stool, and said with a smile: "You're back!" ”

You Mingxu was not polite, he sat down directly on the stool he vacated, crossed Erlang's legs, copied his hands, and looked at the other three blackboards, which almost included all the facts, personnel, confessions and other information of the two cases.

You Mingxu suddenly felt a touch in his heart. After all, Yin Feng is not a policeman, and the victims have nothing to do with him. But he worked so hard.

She beckoned, motioned for him to bend over, rubbed his head herself, and said, "Good work." ”

Yin Feng smiled slightly and said, "Ben Yingjun is not afraid of hardship. ”

You Mingxu also smiled and asked, "You Yingjun, did you find anything after such a big battle?" ”

He opened his mouth, and was about to speak, but he froze again, then his eyes wandered to the side, and he said slowly: "If you find out, what reward will Ah Xu give me?" ”

You Mingxu: "What reward do you want?" ”

He looked very casual and said, "Then just ask for one: the case is solved, you take me out for a day." ”

You Mingxu stared at him twice, smiled, and said happily: "Okay, you pick a place." ”

Yin Feng's face suddenly bloomed with a smile of joy, and the corners of his eyebrows and eyes were swishing, he said: "I made a criminal profile portrait of the suspect in Xie Huifang's case!" ”

You Mingxu frowned slightly: "Tell me." ”

Yin Feng turned sideways and faced the other blackboard, You Mingxu followed his line of sight, and there were indeed several rows of conclusions written there, and he said: "First, the murderer in Xie Huifang's case is between 15 and 20 years old, male. At least medium stature, not thin, often engaged in some physical work or exercise.

Second, he came from a very bad family, lacking the love of his parents and elders, and he had no feelings about it.

third, it was the first time he had killed someone;

Fourth, he often reads some criminal investigation or violent novels and TV series, and is very interested in it.

Fifth, he is thoughtful, patient, and distorted. Therefore, his psychological stress level is very low, which means that he is easily stimulated, causing strong emotional vibrations, and then killing. ”

After saying this in a refreshing voice, Yin Feng turned his head to look at You Mingxu and said, "Actually, I guessed the answer a few days ago." But when we engage in psychology, we must also pay attention to evidence. The various behaviors of the criminals at the crime scene are the key evidence, pointing to the portrait above. And the portrait points us to the suspect. Now, does Xu know who he's going to arrest? One of the most recent people is one who fits this portrait perfectly. ”
