On the other side, Han Yu and Ye Xiaoxiao were in an old house on Crescent Street, Ye Xiaoxiao always sighed that he was fortunate to be wearing black clothes and black pants today, otherwise in this environment, the clothes and pants would probably be dyed. The place where they are at this time is Jiang Linfen's residence on Crescent Street, Ye Xiaoxiao also admires, this house is the house near the ditch where the crime happened last time, at that time, Ye Xiaoxiao and they still thought that no one lived in such a house, but they never expected that such a house would still be inhabited now.

The interior of the house is extremely dilapidated, Jiang Linfen lives on the fourth floor, and the stairwell can be seen from time to time with garbage thrown by people, emitting an unbearable stench. Jiang Linfen's room is a one-bedroom apartment, but the floor height of this house is generally shorter than normal, so the room looks smaller than a normal storey house, the walls inside the room are faded, and the sofa in the middle is also gray and black, and the original appearance cannot be seen, and what is surprising is that Jiang Linfen obviously lives alone, but there are a lot of things in the room, it can be said that except for the sofa, which is empty, and other places are full of things, and I don't know what is inside. It's all neatly packed in boxes, and the only thing that's comforting is that things are neatly arranged, and there is no smell like the staircase.

Han Yu and Ye Xiaoxiao are both very tall, and in such a cramped space, both of them are a little depressed. Ye Xiaoxiao wanted to sit on the sofa, but looking at the sofa that couldn't tell the colors, she dispelled this idea again, she wore gloves, and while checking the things in the room, she said, "Team Han, can't we call a few more people over?" ”

Han Yu glanced at her lightly, "The other colleagues are on the way." ”

Ye Xiaoxiao smiled at this time, it's not that she dislikes it, although this house looks small, but there are too many things, just if she goes through it like this, she doesn't know how long it will take. Now Jiang Linfen's identity has been confirmed, and the cause of death has also been determined, but there are still many things like a ball of intertwined threads, and I can't figure it out.

After a while, some other policemen came, there were many people, Ye Xiaoxiao had to be free, so he went to find the person in charge of the house here, according to him, the house was planned to be demolished, but it was still in the planning and had not been implemented. Jiang Linfen currently lives alone in the house, and she had been persuaded many times before to let her move out, but she resolutely refused to move. Jiang Linfen has lived here for many years, and she also knows the person in charge of the house, and the person in charge saw that she was pitiful, so he simply let her live, but he also said that she could only live until the summer, and she had to move out at that time. And Jiang Linfen herself said that she would stay until the summer and leave when her daughter came back. It's just that I didn't expect the way of heaven to make people, this is just the New Year, it's just early spring, and people are gone.

The group didn't return to the team until midnight. Although it was late at night, Bai Yifan and Cheng Jiaxuan were also in the team, there were a few cups of coffee on the table, and when they came back, Bai Yifan handed them the coffee, "It's still hot, refreshing." ”

Ye Xiaoxiao took the coffee and sat down, "I'm tired today." ”

Han Yu also sat down, and it seemed that the two of them were really tired. Cheng Jiaxuan asked on the side, "Did you find anything?" ”

Ye Xiaoxiao put the coffee on the table and said speechlessly, "Lao Cheng, do you know, I and Team Han are in Jiang Linfen's house just like in the scrap yard, and I don't know what she thinks, the house is full of messy waste products, and there are all kinds of sundries." The point is, there are a lot of things that can't be used, there are broken rice cookers, there are desk lamps that can't be turned on, I don't understand, she is obviously making money herself, why do she keep these things at home. ”

Bai Yifan and Cheng Jiaxuan didn't understand either, Ye Xiaoxiao took a photo of them when they arrived at Jiang Linfen's house, and they were also shocked at that time, there were so many things in the house that there was no place to put their feet.

Han Yu took a few sips of coffee before speaking in a low voice, "I suspect that she has hoarding obsessive-compulsive disorder." ”

"What's that?" Cheng Jiaxuan heard this term for the first time.

"It's a mental illness, and some people call it collection obsessive-compulsive disorder. It's reluctant to throw away used things, and when they choose to decide what to throw away, it's a very painful thing, so they will keep them all, and even take the initiative to search for all kinds of things and hoard them, and in the long run, there will be more and more things, and for them, it will be more and more secure. However, this behavior is generally associated with traumatic psychology. ”

"Could it have something to do with her upbringing?" Bai Yifan asked, and told all the news he got in Laowan Village.

Han Yu nodded, "If that's the case, it may bring her psychological trauma, which will create a defense mechanism, maybe hoarding things is a way for her to build a sense of self-security." ”

"Today, all the things of Jiang Linfen's family have been brought back for inspection, and the scene is also being investigated. It is not yet possible to determine whether the first crime scene was in the ditch or her house. Ye Xiaoxiao frowned, feeling that this question was very difficult. Xiaobai, can you show me Jiang Linfen's photo? ”

"Is it a photo from before I was born?"

"No, it's the scene of the crime."

Bai Yifan pulled up the photo, looking at the photo, she felt that her stomach was churning again at the moment, and she quickly drank several sips of coffee to suppress that feeling.

Ye Xiaoxiao approached the projection on the wall, for Bai Yifan, the uncomfortable picture on the photo didn't seem to have any effect on Ye Xiaoxiao, she carefully touched the person in the photo, and suddenly turned around and asked Han Yu, "Team Han, did you say last time that Jiang Linfen's corpse felt a bit like falling asleep." ”

"Yes," Han Yu also stood up, "Although her hands and feet are tied and her eyes are blindfolded, according to the situation at the scene, there is no trace of a fight." And although she has a lot of things in the house, it is very neat, and there is no trace of any fighting, so it gives people the feeling that everything is her own willingness. ”

Bai Yifan called up a few more pictures of the scene, it is indeed the case, around the ditch where Jiang Linfen was found, there is no trace of it, no wonder there are people passing by every day and not finding it.

If she was willing, then under what circumstances would she willingly let people take her life? And it's still the same after death? Cheng Jiaxuan didn't know if he was asking them or himself. Because he immediately began to answer his own question, "Either the closest relatives or the most trusted friends, but we went to the shopping mall where she worked before, she was introverted, not good at talking, and only knew how to do things, so she didn't have any friends to communicate with." Her parents are gone, her two husbands are dead, and only one daughter is still alive. ”

"Su Yao!" Ye Xiaoxiao said coldly, "But we are just speculating, there is no evidence." ”

"As long as something has been done, there will be evidence. Where does Su Yao live now? ”

"Live right next to the institute." Bai Yifan replied.

"Lao Cheng and I stayed to check the physical evidence, there are a lot of things we brought back today, and the colleagues of the trace inspection estimate that the inspection will not be finished, let's go see if we can find anything useful, Xiao Xiao and Xiaobai will go to the research institute tomorrow morning to have a look."

After Ye Xiaoxiao listened, he took the initiative to say, "I'll go check things with you tonight, I drank coffee, and I just didn't feel sleepy." ”

Bai Yifan also joined, Han Yu did not stop him, although others looked serious, they took care of their colleagues. However, like Ye Xiaoxiao and Bai Yifan, who took the initiative to work hard, he would not refuse, and there were too many things brought back this time, and the strength of the people was great, and everyone would be more efficient together.

After a whole night of hard work, I didn't expect to have a harvest at dawn. From a carton next to the sofa in Jiang Linfen's house, a small amount of cyanide residue was detected, and in the gap next to the carton, half a piece of paper fell, and the fingerprints on it matched Su Yao's. It stands to reason that there is no comparison of Su Yao's fingerprints, but the last time she came to the criminal police team, Ye Xiaoxiao always felt that this woman was a little strange, so she had an extra heart and deliberately poured her a glass of water, and fingerprints were left on the cup.

Han Yu asked Cheng Jiaxuan and Ye Xiaoxiao to bring Su Yao back to the team, the research institute is a configuration of the medical school, mainly to do some medical research, the people who work here are not low in education, and they are also very professional in medical things. Ye Xiaoxiao and Cheng Jiaxuan arrived very early, and no one at the institute had gone to work yet, so the two came directly to Su Yao's residence next to them, Ye Xiaoxiao knocked on the door first, the door opened from the inside, Su Yao had exquisite makeup, holding a small bag in her hand, and she looked like she had just packed up and was ready to go out.
