"I've read Fang Yi's files. His real situation is that his parents died and were sent to an orphanage. In the orphanage, he was adopted several times, but soon after each time, he was sent back with injuries all over his body - I checked the information at that time. Once, because the adoptive family had a new child, he didn't need him. He was beaten or scolded. He couldn't stand running back to the orphanage. Once, he ran back because he was molested by the adopter. But the orphanage is also to calm things down, not for him. It can be seen that he suffered a lot when he was a child. So he wants to be a policeman. Later, someone funded the orphanage to set up a school. He studied hard and wanted to stand out. "

"Then he is really poor." Yunjin has lived a happy life and a happy family since childhood. I never imagined that there are so many children in the world who are still suffering.

Fang Yi had never thought about such a situation.

"Yes, he wanted to be a policeman. But I don't know why his excellent files were returned by the police several times. I have read some information, probably because he received several psychological treatments when he was in school. The police station is worried that he is incompetent. Of course, the vice president didn't help him, which shows his mercy. "

Yunjin nodded gently: "maybe his childhood experience really left him too much psychological shadow. He was excellent at school, but I met him and never made any impression. I feel that he is the kind of person who has both a very sense of existence and a very non sense of existence. It feels like a special contradiction. "

"When I first saw him, I also had a strange feeling. But I didn't expect that he would kill. And I didn't expect that he was not the son of the vice president. His superficial identity still confused me. "

"How did you find out later?"

"Do you remember the first time I said that the murderer was skillful?"

"Remember." Yunjin nodded.

"I also said that the killer's dominant hand was his left hand. I have seen Fang Yi several times. He always works with his right hand. But on the tiger's mouth of his left hand, there were traces left by holding the knife for a long time. Later, Guo Tong inadvertently said that Fang Yi was an orphan and had good cooking skills. I think Fang Yi must be hiding his habitual hand. Moreover, people with good cooking skills generally have good knife skills. When they know that he is an orphan, I guess he will cook and cook himself. He may even cook and cook for other children from childhood. "

Yunjin nodded.

"Then I checked the lives of all the victims and found that they all have a common feature." Song Yancheng said, "all these victims have participated in a property dispute case. The last time I asked you to pull out a civil dispute case from the file. "

"I remember, I also helped you find the file."

"These victims, more than ten years ago, had a lawsuit with a husband and wife with the other surname. The couple surnamed Fang sued them for conspiring to seize a shop on the street, which was the steamed stuffed bun shop on which the Fang family lived, and their whole family lived there. But I don't know why, the couple surnamed Fang lost the lawsuit. They were driven out and displaced with their children. "

Yunjin was flustered when she heard this: "are those Fang Yi's parents?"
