When they got in the police car, Liu Jiaming pointed to a window in the old residential area and asked,

"Can you see that figure?"

The moonlight shone down, illuminating a fat old lady in a white nightgown standing in front of the window. Police cars and ambulances were coming one after another on the main street, and a noisy group of people rushed down, and another group of people got on the car and drove away. Anyone who hadn't fallen asleep would come out to see the excitement.

Yi Jiayi also saw the old lady, of course, but seeing that Liu Jiaming looked like he suspected he had seen a ghost, he said calmly,

"No, isn't it just a white window curtain?"

Liu Jiaming stared at Yi Jiayi in disbelief for a while, and seeing that she was still serious, he rubbed his eyes and looked again, and it was still a fat old lady. The white robe was shining with a cold light, as if it would fly through the air towards him the next moment.

The police car started and drove until it turned out of Daquan Street and onto Tai Kok Tsui Road. Liu Jiaming was still craning his neck to look back, afraid that something would chase him.

Fang Zhenyue stretched out his foot and bumped Yi Jiayi's foot. The young policewoman smiled and said, "Everyone can see it. A fat old lady is watching the fun." "

?" Liu Jiaming turned around and immediately became furious. He quickly punched Yi Jiayi's forearm.

The atmosphere on the return trip was not too heavy at last.

Arriving at the police station, Zhang Dafu was temporarily detained in the interrogation room. The cold headlights were on, he sat on the bench, and waited alone.

Fang Zhenyue led the team to sort out the follow-up matters. A few minutes later, when he was about to talk to Zhang Dafu, Chen Guangyao, who was still in the dilapidated area, called.

"Zhang Dafu's house was the scene of the first murder. All the victims were imprisoned and tortured here until they were strangled to death by the murderer.

"Hair of different colors and lengths has been collected as evidence. I'm afraid that the murderer has killed more than 6 people so far.

"In the closet in the main house, 9 sets of stacked clothes were found. Each set was complete, from underwear to outerwear, socks and shoes. The clothes were unwashed 'trophies' taken from the deceased. The deceased's DNA and other information should be able to be extracted... This closet is the neatest and cleanest part of the whole house..."

In order to serve Fang Zhenyue's interrogation, Chen Guangyao tried his best to report as many clues and speculations as possible. As he spoke, his tone became heavier.

They have seen a lot of bad guys, but they have never seen such a perverted one.

"During the internal fight in the cart of Zhang Dafu's mother, human blood and some human tissues were collected. It is preliminarily inferred that this cart was used to dump corpses.

"There are a total of 4 chopping knives in the house, and the blades of all of them are bent...

" "Sir Xu is leading people to dig corpses in the wasteland in the yard with headlights on. They have found 2 heads and some body fragments. The murderer did not bury it deep, and he should have done it secretly at night. The people living nearby are all poor elderly people, and they go to bed early... There should be more gains later."

"Yeah." Fang Zhenyue nodded and replied politely:

"Zhang Dafu's mother has confessed. Her son found two jobs after graduation, but quit or was fired within a month each time, and has been living off his parents ever since. She supported her son by selling fruit, and dumped the body on Ferry Street on her way to the wholesale fruit market across the street.

"In the murder case, she was responsible for luring the victims to help her pick oranges, or to help her push the cart uphill. She used women's sympathy and kindness to lead the victims to the alleys or corners where she and her son had agreed to meet.

"After her son killed the victim, she was responsible for following her son's arrangements and dispersing the bodies. Bodies have been dumped in various wastelands and garbage dumps in Sham Shui Po.

"I have sent people to search for the body, and I will notify you if I find anything. "

...How could this happen? Not only did he not care about his good son, but he also..." Chen Guangyao took a deep breath, suppressed his emotions, and then said, "Okay, thank you for your hard work, Sir Fang. I will continue to collect evidence."

"Well, you have worked hard, too."

After hanging up the phone, Fang Zhenyue was silent for a while before walking out of the office.

According to the confession of Zhang Dafu's mother, her husband had a violent temper. At first, he only beat her and her son after drinking. Later, even when he was sober, he would not show mercy.

In this family, the father played the role of a violent abuser, and the mother played the role of a numb doter.

The extreme growth environment, the inability to adapt after entering society, and the next ten years of living at home and relying on parents have gradually destroyed their family. Zhang Dafu.

In the second year of Zhang Dafu's life, he and his mother killed his drunk father.

A few months ago, he had a huge conflict with a prostitute because he was inhumane when hiring a prostitute, and killed a woman for the first time and raped her corpse.

After that, it was out of control.

When this story was gradually pieced together, no one felt relieved.

Zhang Dafu in another interrogation room had not confessed yet. He sat there like a wooden block, with his head down. I don't know what he was thinking, but he didn't say anything.

Gary and his friends couldn't do anything to him. The police have long banned forced confessions. Even if you know full well that this person is the murderer, you cannot use force if he won't talk.

When facing such a person, you can only wait and see. When he is tired and lets down his guard, you can use interrogation techniques to squeeze out a confession bit by bit and dig out the truth.

Fang Zhenyue saw Yi Jiayi leaning against the small window, watching the interrogation with a frown, "Didn't I tell you to go home? Why are you still here?"

He looked at the watch and it was already early morning.

"Brother Yue, a smart, inferior, and cynical person, so scary. "

According to the description of the murderer's mother, Zhang Dafu is a very smart person. He knows all the principles that others don't understand, and he can learn things that others can't do immediately after studying them.

Once, Zhang Dafu was also a good boy who could help the neighbors solve various difficult and complicated problems. Everyone praised him for his future prospects, and he himself was confident in this.

Until he entered the society, everything he had imagined to be easy to get became difficult, and the bright future suddenly became distant. His sensitive, fragile, and extreme personality was revealed, and gradually became more sinister and terrifying than his tyrannical father.

Thinking back to these variables, the little policewoman turned into a sad eleven.

Fang Zhenyue walked over, put his arm around her back, and led her out of the interrogation area, saying as he walked:

"Not all people with low self-esteem will completely give up on themselves. Not all cynical people will take revenge on society. Not all smart people will use their wisdom on such things. These are just individual cases. There are many more of us who are struggling and unwilling to give up in dire situations. Take a look at these, go back and have a good sleep, and forget about Zhang Dafu. "

He said it as if he had forgotten about that scumbag.

At this moment, everyone else was busy at their respective posts. He had a moment of leisure before the Forensic Science Department and the Medical Examiner's Department went back to the police station after investigating the scene.

"I'll take you home."

The streets were very quiet in the late night. Even in the city that never sleeps, people were asleep now.

Because it was really late and they had been through so much today, Fang Zhenyue took Yi Jiayi all the way to the door of her house.

Yi Jiadong hadn't slept yet. He endured the sleepiness and waited for his sister. Only after he received his sister from Fang Zhenyue did he bow his head to sleepiness and say goodbye to Sir Fang.

After closing the door, he closed his eyes, went back to the boys' room and fell asleep.

He didn't even have the energy and energy to say good night to Yi Jiayi.

He didn't have to go to work the next morning, so he could take a nap.

Yi Jiayi canceled the alarm clock and left a note for her brother telling him not to worry about her getting up and breakfast. Then she washed up and went back to bed.

Jiaru on the upper floor slept soundly, but Yi Jiayi tossed and turned and couldn't sleep.

Only when she recalled what Fang Zhenyue whispered to her when he accompanied her to climb the stairs did she finally calm down and gradually fall asleep.

In her dream, there was still a low and reliable voice comforting her heart, and it was still that sentence:

[Perhaps without the key points you mentioned, we can still solve the case, but without the idea of ​​merging the cases, and without the dumping site moving north to Sham Shui Po, we may not be able to capture the clue of the old lady selling oranges so quickly.

A few days later, or maybe just a few hours later, the victims rescued today would all die. Even if we solve the case a week later, more than one victim will die, and more than one family will be destroyed.

Eleven, this job is hard, and I know you are in a heavy mood now.

But you also have to understand what good you have done. The victim rescued tonight will come out of this nightmare. Human beings are sometimes stronger than you can imagine. Whether she gets married and has children or has a successful career in the future, all her long existence will be due to your contribution.

This is also the benefit of our industry that others cannot see. You must experience this sense of significance, this sense of accomplishment, this sense of happiness from strong self-identity and self-awareness, and even think that you are great.

Keep it as a secret, quietly enjoy this special spiritual reward of being a police officer, and then have a good sleep and have a good dream.

Thank you for your hard work, great little detective. 】

In the dream, the bitterness was washed away, and the corners of the little policewoman's lips finally showed a sweet smile.

She is very useful, she has helped and saved people...
