Patient's Name: Yu Lixin

Clinical diagnosis: impulsive personality disorder

After reading this list, I looked up what impulsive personality disorder means on the Internet:

Impulsive personality disorder arises from unconscious instinctive impulses, which release a person's nervousness, resulting in a sense of relief and pleasure, which occurs when self-control fails. At the same time, people with this personality will burst out with a very strong burst degree due to the mental stimulation of a smile, which can cause serious injuries and property damage.

"Xiao Yang, there is a woman who said she wants to look for you."

Who's coming here to look for me at this time? I walked towards the door of the police station, and the person standing at the door was Fang Han (Fang Yin's sister)

"Hello, I am Fang Yin's sister who contacted you last time, I just finished dealing with my sister's funeral, I want to come to you to say something, I don't know if it will help you find the murderer."

I finally waited for her to come to me, because as Fang Yin's sister, she can know more about Fang Yin, so that our case can progress faster, because through the social relations of the deceased, we can always know some clues, these are very important to us, the reason why we haven't investigated Fang Yin's things in the past few days is because: a few days after Fang Yin was killed, we received Yu Lixin's matter, on the other hand, because because of the Chinese New Year, we can basically find all the people we can find, The clues we told us were basically irrelevant, and the rest of the people were in different places because of the Chinese New Year, and it was more difficult for us to find them, so after thinking about it, we still chose to wait for his sister, that is, Fang Han, to come to the police station after contacting Fang Yin's local social relations and tell us more detailed things, after all, this can save us a lot of time and manpower.

Fang Han's arrival undoubtedly relieved all of us, at least Fang Yin's murder can make some progress.

"It's finally waiting for you." I said.

"I'm sorry."

"You can sit down first."

Fang Yin in Fang Han's mouth didn't seem to be happy at all

Fang Yin's parents chose to divorce when their two sisters were still in high school, and soon after the divorce, they each had a new family, and the couple basically ignored their sisters, and even later they completely lost contact with their parents, at that time Fang Han also happened to be admitted to college, because she had to pay her sister and her own school tuition, she worked part-time all the time, and in her sophomore year, he chose to drop out, on the one hand, because she often went out part-time and wasted too much class time, Therefore, he began to be unable to keep up with the progress of the teacher's classes, and the money she had part-time was not enough for herself and her sister Fang Yin's tuition, and there were only two options in front of her at that time: either she would drop out of school, or Fang Yin would drop out. Of course, it was obvious that she had chosen the former, but she was only twenty years old herself.

Fang Han said that she only hoped that her abandonment would give Fang Yin a better future than herself, after all, she was still in high school, she still had a long way to go, and she had seen the world for a few years more than her sister.

The parents of the two of them have been "yin and yang" since they were children, and they made a little mistake, and they would say why they gave birth to the two of them, so Fang Yin has been a very introverted character since he was a child, he doesn't talk to others much, he always likes to do his own things, and even once he was hit by a car and didn't dare to tell his parents when he went home, because she was afraid that it would be her mother's blame, she would occasionally tell Fang Han something about what happened to her at school, but more often than not, she didn't have much communication with Fang Han.

Later, Fang Yin was admitted to university, and he also began to earn tuition part-time, Fang Han said that his pressure was actually reduced a lot at that moment.

Fang Yin, who went to college, began to change, and began to talk to Fang Han about what happened in college, and Fang Yin was also successfully admitted to adult college, she said that if she didn't go to college, she would always feel a little regretful in her life.

"Fang Yin had a boyfriend when he was in college, his name was Yu Lixin."

"What! What is it called! Yu Lixin! ”

I bounced up from the chair I was sitting on and asked in shock, because my voice was so loud that even Zhang Kai in the office heard it, and he also rushed out of the office and said, "Xiao Yang, what's wrong with Yu Lixin!" You're so loud. ”

No, it was everyone in the office who handled Yu Lixin's dismemberment case and looked at me after hearing my words.

For a while, I didn't know whether to answer Zhang Kai's question or say something to respond to everyone's gaze.

"Yes, she had a boyfriend named Yu Lixin in her sophomore year, Officer Yang, why are you so shocked." Fortunately, Fang Han then answered my question, and at this time, Zhang Kai and several other colleagues also stood by my side.

"What's the matter, you say it again, what's the matter with Yu Lixin?" Look, I'll just say that it's not that my reaction is too strong, because we didn't think that we would have too much contact with Fang Yin's case when we received Yu Lixin's case, and the clue we heard at this moment means that these two cases must be related, because we have been looking for a domestic violence man before, that is, the man who came over to domestic violence Fang Yin when the aunt in the guard room of the family home told us that it was okay.

"So you've heard your sister say that Tai Lixin beat her."

"I hadn't heard her mention it, but when she came back from her junior or senior year, I saw bruises on her arms and legs, and I asked her, and she said she had fallen. But it can be seen that the truth is not as she said, because the bruise looks like someone else beats, and I didn't ask him much at the time, because I know her, and she won't tell you a little bit of what she doesn't say, no matter how much you ask. ”

"And later?"

I asked her then.

"Then they broke up within a year of her graduation, and she looked relaxed on the day she broke up."

Yes, how could it not be easy, because of this man, she may have suffered pain that others could not understand, at least in terms of body.

"Do you know what happened next?"

"Later, she lived in the current apartment after work, I would come over from time to time, she was with Su Shao later, that person was very good to him, they were actually ready to get married."

"Su Shao?" This person appears as Fang Han's new character relationship, and we don't know what we can get from him, which will be our next work.

"Thank you, this information you gave us is very helpful, and we will give your family an explanation of your sister's matter." I couldn't help but say, in fact, for what the truth of the matter is, the family of the deceased wants to know more than us, after all, a corpse is more for us who investigate the case to give an explanation to the public, to avoid everyone's panic, and to increase some admiration for the profession of the police, and the deceased killed in the case may be a lifelong pain for the family.

On the other side, Wang Zhiyi went to the hospital to ask Yu Lixin's attending physician about something, of course, the hospital where Yu Lixin was treated and his attending physician, we all knew about it on his list.

"How so? Guys over there at the hospital. Zhang Kai asked.

Wang Zhiyi picked up the water on the table and glanced at me, I nodded, he picked up the glass of water and drank it violently, and it was obvious that he was really thirsty and "died", although I didn't know him for a few days, but it was also because of the fact that I was inseparable from him in the past few days of investigating Fang Yin's affairs, and the tacit understanding between us seemed to have known each other for several years, before he entered the door, I estimated that he should come back after I finished talking with Fang Han, and he has a habit of drinking a large glass of water every time we go out and come back, And it must be warm water, I have to complain about this, his habit is not what a young man should have, what hot water does a big man drink every day, I really can't understand, he said that people should be healthy in advance when they are "old", and water replenishment is the most effective method, as for where he got this conclusion, there is no way to know.

Wang Zhiyi put down the water in his hand that had been drunk, took a deep breath and said:

"Yu's attending physician said that when he came to the doctor, he knew that he had this disease, and he had been examined in other hospitals before, but there was no result after taking the medicine, so she re-examined the place where she was treated now, but the results were obvious, there was no problem with the diagnosis in the hospital before, he did have this disease, and there was no problem with the medicine prescribed, as for why he had no effect after taking the medicine, this has to make people wonder whether he took the medicine on time according to the doctor's instructions."

Why didn't he take his medicine?

A normal person will try his best to get better as soon as possible when he knows that he has a problem with his body, and why does this person still not take medication to alleviate or alleviate the symptoms of his disease after he is diagnosed?

We don't know what was going on in his mind, but maybe he had some unique idea of his own to face his disease.

"Pack up our things, let's go look for Su Shao, we just found out his address." Zhang Kai said with the notebook he often carries with him in one hand and his cup in the other.

Su Shao is also the current boyfriend of her sister that Fang Han just mentioned, and we didn't know about his existence until Fang Han talked about him this time.

Then again, why no one mentioned him among the people we asked before, it seems that his existence does not seem to have much "value", but it adds a little more mystery to him, what kind of character is this, whether he will be the murderer of Fang Yin, all this we can't define until we meet him in person.
