When I came out of the detention center, it was already dark.

Xiao Ran did not choose to get off work, but followed Wang Liyang to Dai Xiaorong's doorstep.

Wang Liyang said that Dai Xiaorong's father was a 49-year-old son, and because he was born late, Dai Xiaorong was pampered since he was a child, and his personality was not well shaped.

When Dai Xiaorong was 10 years old, his father died of illness, and since then he has no restraints, and he rebelled and fought when he went to school, so he dropped out of school.

Dai Xiaorong and his mother live in an old apartment building, dilapidated and dim, and the walls are covered with layers of small advertisements.

According to Wang Liyang, after Dai Xiaorong was detained, his mother was persuaded to leave by the hotel.

Moreover, Chai Shaoying's relatives also went to Dai Xiaorong's house to make trouble because of anger, so that Dai Xiaorong's mother was worried all day long and did not dare to go out easily.

When I came to the door of Dai Xiaorong's house, there were traces of red paint on the dilapidated iron door, and there were two lines of blood-red characters on the walls on both sides of the door: "Murder pays for life!"

I knocked on the door, and after a long time, I heard a faint footstep in the house, and the footsteps stayed behind the door, as if he hesitated for a long time: "Who, who?"

Wang Liyang paused for a moment: "Hello, policeman." ”

As soon as the words fell, the iron door that seemed to be unusually heavy was pulled open, and a gray-haired aunt stood in the door excitedly and nervously, rubbing her hands together, with eagerness in her eyes, and said, "Is it clear? My son is not a murderer?"

"I'm sorry, for the time being, Dai Xiaorong hasn't been suspected of being photographed yet. Wang Liyang's voice was very low.

The light in Dai Xiaorong's mother's eyes quickly dimmed, and she said a little sluggishly: "Then, please come in." ”

The furnishings in Dai Xiaorong's home are very old, and the only household appliance that can be on the table is an old color TV more than ten years ago, and there are advertisements on the TV, but there is no sound at all, like watching a pantomime.

"Dai Xiaorong usually lives in this room, so you can go in and see whatever you want. ”

Wang Liyang pointed to a messy room, the situation inside was still the same as after the search, thinking that the police had not been passive since the search.

"Comrade policeman, it's really impossible for my son to kill people, it's really impossible, I know that he hasn't been a good boy all these years, but he is not bad in his heart, he doesn't dare to kill chickens at home, how can he have the courage to kill people. ”

Dai Xiaorong's mother sat on a small horse, her hands hanging weakly on her knees, and kept repeating.

Xiao Ran walked into Dai Xiaorong's messy room.

The room was as shabby as the outside, with a small bed pressed against the corner, pillows placed against the corner, and the window opposite the pillow, where all the transparent areas were covered with thick newspaper.

Under Dai Xiaorong's bed, there were still a few comic weeklies, Xiao Ran put on gloves, picked up the top one, patted off the dust, and the date of publication was two days before Dai Xiaorong's incident.

"These, is there anything worth noting?"

Shan Yuesoft looked at Xiao Ran in confusion and flipped through the comics: "This place has been thoroughly searched, and there is indeed no special suspicion." ”

Xiao Ran closed the comics, walked to the door and said to Dai Xiaorong's mother: "Auntie, does your son like to read comics very much?"

Dai Xiaorong's mother looked at the comics in Xiao Ran's hand, and didn't understand what Xiao Ran wanted to ask, so she was stunned for a while before nodding and said: "Yes, he has always liked to read this comic, and he will buy a copy on time every Sunday, and the new one is so expensive, every time I say that he doesn't listen, he keeps buying, and keeps buying ......."

Xiao Ran took out his mobile phone, took pictures of all the furnishings in Dai Xiaorong's room, took pictures of those cartoons, looked up and said: "Auntie, don't worry, we will definitely investigate the matter clearly, and we will not wronged a good person, nor will we let go of a bad person." ”

"Thank you, thank you, I just want to know if he did it, if he really did it...... I don't want to think about anything anymore, I just want to know what's going on......"

Dai Xiaorong's mother covered her cheeks with her hands and burst into tears.

Coming out of Dai Xiaorong's house, Wang Liyang drove back to the bureau in a police car, while Xiao Ran and Shan Yuerou stood on the side of the road, preparing to take a taxi back to their respective homes.

"Xiao Ran, what do you mean by taking those photos just now?" While waiting for the bus, Shan Yuerou couldn't help but ask.

"I ...... just constructed the psychological characteristics of Dai Xiaorong before and after the crime. Xiao Ran said.

"Oh, by the way, you also have a degree in criminal psychology. ”

Shan Yue said softly: "Then according to your judgment, what kind of psychological state was he in during that time?"

Xiao Ran thought for a while and said: "Just like what was said in the dossier, he was timid and afraid, but he was a little naïve and fantastic. ”

"From what point of view?" asked Shan Yuerou.

"Have you noticed, the bed Dai Xiaorong slept on was a very small bed, against the corner of the wall, and on the side of his quilt, there were traces of friction against the wall. ”

Xiao Ran took out his mobile phone and pointed out the photos he took to Shan Yuerou: "This shows that he is afraid of the night, and when he sleeps at night, he always puts one side of his body against the wall, and the top of his head is against the wall, and the only window that may bring uneasiness is still covered with newspapers by him, and he can always be within the range of his vision."

- Only people who are insecure in their hearts like to shrink themselves in a corner, and when such people are sober, they will want to show their strength more and more, which is why he is always mixed with those gangsters, because those people seem to be afraid of anything, which can give him the illusion of security. ”

"What about naivety and fantasy?" asked Shan Yuerou.

"You look at these comics, they are all for elementary school students, and even the senior children in elementary school don't read them, but Dai Xiaorong bought them all without landing in one issue. ”

Xiao Ran said: "The last issue of the comic he bought was on July 1st, Sunday, and Chai Shaoying's accident was on July 3rd, in just two days, it was almost impossible for a person whose real psychological quality was still at the level of a teenager to mutate into a villain with the intention of killing." ”

Shan Yuerou nodded and thought about it.

The forensic report also said that Chai Shaoying died between 12 and 1 o'clock in the morning, which was the dark night when Dai Xiaorong was afraid, even if he had the intention to kill someone, he would not do it so simply. ”

Xiao Ran continued: "Assuming that Dai Xiaorong really changed his psychology and became a person with a strong desire for crime, he removed all the footprints in the villa, why did he leave only that piece of toilet paper?"

Shan Yuerou understood what Xiao Ran meant: "In other words, we can now temporarily determine that Dai Xiaorong did not commit the crime and go all out to investigate in other directions?"

"So, go back and have a good night's rest, and we'll probably be busy again...... Your car has arrived. ”

Watching Shan Yuerou's taxi disappear into the depths of the lights, Xiao Ran looked at the stars in the night sky.

Hopefully tomorrow will be a good day......
