After Han Cheng copied all the surveillance videos back to his computer, he used the double-speed viewing skill to watch all the videos in less than half an hour.
The final scene was framed, and he locked in his mind a suspect who left Nanshi by train shortly after the four cases occurred.
Han Cheng took a picture of the suspect's face captured on surveillance and asked Chi Shen to take people to the train station to investigate the person's personal information.
Soon, Chi Shen reported back the news from the train station: the suspect's name was Song Jian, 35 years old, who lived in Dongshan City, Linshi, Nan City, and had a history of theft.
Everything is right!
The Second Criminal Police Team quickly dispatched police to arrest Song Jian and escort him back to the Jiangnan Branch.
At first, Song Jian avoided the serious issues and only admitted that he was responsible for the Yu Dan case.
Song Jian may have felt that he neither killed anyone nor stole anything in the Yu Dan case. Even if he confessed, he would at most be detained for a few days and then released.
But after finally finding out the murderer, Han Cheng would not let him get away with it so easily.
In order to find more evidence, Han Cheng invited handwriting experts to conduct handwriting forensics by comparing the words engraved on the three corpses with the words Song Jian usually wrote.
After repeated comparisons, handwriting experts finally gave the identification result that the special characters carved on the faces of the three female corpses were written by Song Jian.
Later, Han Cheng and the others also found a hood with blood stains on it at Song Jian's house.
After examining the bloodstains on the hood, it was found that it contained the bloodstains of the three deceased women, Ye Xia, Kang Hong, and Wanqing.
In the face of irrefutable evidence, Song Jian finally lowered his arrogant head, truthfully confessed the numerous crimes he had committed, and also told about his criminal path.
His family of origin may be the origin of his crimes.
Song Jian's father was a gambler or an alcoholic, and his mother was a dancer in a ballroom, and she was also a money-worshiping girl. After the two gave birth to Song Jian, they left him to Song Jian's grandfather to raise him.
Grandpa Song Jian was an intellectual, and Song Jian also fell in love with literature.
But the good times did not last long. When Song Jian was 7 years old, his grandfather passed away.
Song Jian was handed back to his parents who were addicted to gambling and money worship.
Since then, Song Jian has been living in a family full of quarrels and violence.
Song Jian's parents were extremely irresponsible parents. They never cared about Song Jian's life or death. Song Jian's childhood was almost lived in pain and hunger.
When he was young, Song Jian had no choice but to engage in petty theft because he had no money or food.
When he was 10 years old, his father was hit and killed by a car because he was drunk and crossing the road.
Later he lived with his mother.
At this time, his mother was fired by the owner of the dance hall because of her old age and sex, and she had no source of income.
But she remained stubborn, still greedy for enjoyment, hung out with all kinds of men, and never cared about Song Jian's affairs.
In the end, when no man was willing to give her money, she started a sex business at home, and she didn't care about Song Jian's feelings.
Sometimes she even asked Song Jian to look after her.
If Song Jian doesn't follow her instructions, she will give her a severe beating.
From that time on, Song Jian began to hate prostitutes.
Later, when he was 17 years old, Song Jian's mother was killed by a prostitute at home because she couldn't agree on a prostitute.
Song Jian, who was in high school at the time, returned home and saw his mother lying quietly in a pool of blood with a knife stuck in her chest.
Instead of feeling sad and fearful, he felt very happy. He even cursed in his heart, "You deserve to die!"
After that, Song Jian dropped out of school and entered the society early. His way of making a living was to break into houses by flying through windows.
Because he is a little clever, he knows how to avoid surveillance and find some old communities to commit crimes when the owner is not at home. In addition, he is agile, so he is rarely caught.
At the age of twenty-nine, Song Jian accumulated a large amount of wealth through theft. At this time, he began to long for a family.
Later, someone introduced that Song Jian was married to a woman named Yang Xin. Yang Xin had an outstanding appearance and an amazing figure. Song Jian was very satisfied with this beautiful wife.
The only thing he was dissatisfied with Yang Xin was that this woman worshiped money just like his mother and always spent money lavishly.
But these are not big problems and he can accept them. After all, Yang Xin can spend a long time just once if he goes out to steal.
Song Jian is from Dongshan City. In order to avoid police investigation, he never steals in this city. He often chooses to steal in other places. Nanshi is the city he visits most often.
Yang Xin never asked Song Jian where his money came from. Anyway, as long as Song Jian gave her money to spend, she would be his canary willingly.
However, two years after the two got married, Song Jian learned a shocking secret about Yang Xin from a fellow villager.
The fellow said that Yang Xin used to be a housekeeper on Hong Kong Island, and he also took care of her business.
The so-called Lou Feng is actually another name for prostitute.
After learning this shocking secret, Song Jian was like a bolt from the blue.
He never imagined that his beloved wife was once a prostitute!
A feeling of disgust arose in his heart!
This was a very heavy blow to Song Jian!
Scenes from the past reappeared in his mind.
He thought of his mother, who had also been a prostitute, and of the perverted pleasure he felt seeing a sharp knife inserted into a corpse.
At that moment, he had a perverted idea to kill all the prostitutes.
And once this kind of thought grows, it will take root and sprout in his heart like a seed and cannot be contained.
He wants revenge on the prostitute!
Once, he came to Nanshi to commit a theft. When passing a club, he saw Yu Dan, wearing scantily clad clothes and heavy makeup, walking out of the club alone.
Looking at the coquettishly dressed Yu Dan, he felt that this woman must be a prostitute. He immediately felt a sense of disgust in his heart and had an urge to kill her.
So he followed Yu Dan to her residence, and while Yu Dan was asleep in the middle of the night, he flew into the house through the window and tried to kill Yu Dan.
That was the first time he intended to kill someone. He was very nervous. When Yu Dan discovered it, he was so frightened that he dropped the knife and ran away.
Later, the more he thought about it, the more he felt useless, so he bought some chickens and ducks home with his wife on his back to practice the feeling of "killing".
He used a knife to cut the live chickens and ducks one by one. When he heard the screams of the chickens and ducks, he felt an inexplicable pleasure.
Soon, he was no longer satisfied with the shallow pleasure he found in live chickens and ducks.
He shifted his target to living people again.
Therefore, Ye Xia, a dance coach with sexy clothes and outstanding appearance, became his target.
In his inherent thinking, he believes that beautiful and sexy beauties are prostitutes and should be killed.
After "Ling Chi" tortured Ye Xia, Song Jian felt an unprecedented pleasure.
After killing the person, he saw that the police did not suspect him at all, so he began to defy the police, and the crime began to escalate step by step.
He thought that with his intelligence, the police would never catch him.
But he never expected that Han Cheng, the evil nemesis, would appear in Nanshi.
"Song Jian, since you hate prostitutes so much, why didn't you kill your wife?"
At the end of the interrogation, Han Cheng asked Song Jian one last question.
Song Jian was stunned for a moment, then sneered: "Actually, she is the one I want to kill the most, but I have thought about it. If I kill her first, your police will definitely suspect me immediately. I want to wait until I am outside After killing 99 prostitutes, I will kill her again to collect 100, then I will have no regrets!"
