"Do you recall it carefully, apart from screaming, is there any other sound?"

I looked at the man earnestly and continued to ask.

"No, only a scream, the sound insulation of this residential building is still relatively good." The man said in a deep voice.

"What time did you hear the screams?" I looked at him and continued to ask.

The man recalled a moment and said to me, "It was about one o'clock in the middle of the night. ”

"Okay." I nodded, handed him over to Officer Wang for a transcript, and turned around and walked into the residential building.

On the fourth floor of the crime scene, I picked up the cordon and walked into the crime scene.

In the living room, Jiang Tingbai was leading a team to conduct on-site investigation.

Going around the entrance, I saw a dead man sitting in a chair.

It was an ordinary domestic chair, four-legged with armrests.

A man covered in blood sat in a chair, and there were large blood stains on the ground.

The chair was against the wall, the man's hands and feet were secured to the armrests and legs of the chair by ropes, and his neck was also secured to the back of the chair by a rope.

The man's head hung down, already dead.

This type of bondage completely restricts the man's ability to move, and it is a standard mode of interrogation bondage.

Of course, none of this shocked me, I've seen too many ways to kill people over the years.

What really struck me was a huge blood-dripping six-pointed star pattern on the wall behind the man, along with a big X.

Officer Wang is right, this is a serial murder case, and the murderer is also X of the Hexagram organization.

"It looks like this is the murder weapon."

Jiang Tingbai looked at a household kitchen knife on the floor of the living room and said seriously.

This time the crime scene was not as chaotic as the last time, and there was no trace of a fight at the scene.

On the ground at the scene of the crime, there was nothing but a blood-stained kitchen knife.

The technical team immediately conducted a trace inspection of the kitchen knife, focusing on extracting fingerprints on the kitchen knife.

"Are there fingerprints?" I walked up to Jiang Tingbai and asked seriously.

Jiang Tingbai nodded and showed a smile: "There are fingerprints, and the murderer can be found now." The vase is used to blame, and I don't believe that this kitchen knife is also used to blame. ”

This is definitely a major discovery, and it is very likely to be the key to clearing Ye Yun's suspicions.

I made up my mind and turned around and walked over to the deceased.

As the distance closed, I finally saw the tragic situation of the deceased.

On the deceased's right hand, only one thumb remained, and the other four fingers were severed and thrown under the chair at will.

"There are obvious coercive wounds on the deceased's body, and the murderer must have wanted to ask for some clues from the deceased's body." Ren Qiushi said lightly.

"It seems that the scream last night was because the murderer cut off the finger of the deceased." I said in a deep voice.

"That's right, ten fingers are connected to the heart, and the severe pain can make the deceased faint in an instant, so there is only a scream." Li Meng, who was beside him, echoed a sentence.

I nodded and asked, "What is the cause of death?" ”

Ren Qiushi gently held up the deceased's drooping head and pointed to a wound on his neck that turned out: "This is the cause of death." ”

"The murderer fixed the deceased in a chair and inflicted harm on him, wanting to get some content. During this time, he cut off his fingers with a kitchen knife, and finally wiped his neck with a kitchen knife. Zeng Lan carefully described the whole incident to us.

After a while, Lin Zifan walked into the scene of the crime and brought us the identity information of the deceased.

"Team Qin, the deceased's name is Huang Youfu, he is fifty-six years old this year, and this house is in his name. Eight years ago, he was sentenced to eight years in prison for child trafficking, less than half a year after his release. Lin Zifan said to us seriously.

"Child trafficking again? As with the previous deceased, it seems that the murderer's motive for killing was obvious, which was to carry out revenge torture against the perpetrators of child trafficking. Li Meng said seriously.

I nodded and continued to ask Lin Zifan: "Do you have any other clues?" ”

"Huang Youfu is not a core member of the child trafficking criminal organization, he only acts as a contact buyer in the entire child trafficking case. After the incident, he confessed that he had helped children to find buyers for more than 20 years, and the police had found six abducted children according to the clues he provided, but two more abducted children had not been found. However, according to the police investigation at that time, there were by no means only eight cases in which he was suspected of being involved in the sale of children, but there was no actual evidence, and no important clues were found. According to the case file investigated, Lin Zifan told us about Huang Youfu's crime.

"Judging from the scene, the murderer must have wanted to get some news from the deceased. Combined with his criminal record, it is likely that the killer was the parent of an abducted child who wanted to get his child's whereabouts out of his mouth. Li Meng was suddenly a little excited, and said indignantly.

"That's right, Zifan, didn't you say that there are still two abducted children who have not been found? Investigate the parents of the abducted children in both cases. Thinking of this, I quickly explained to Lin Zifan.

After listening to my words, he showed a confident expression: "Don't worry, Team Qin, I have already sent someone to do this." ”

We looked at each other and smiled, but didn't say anything more.

When I was the head of the criminal police detachment, Lin Zifan was the criminal police under me, and we got along for many years and had a very tacit understanding. Especially after we all came to the serious crime team, Lin Zifan is my right-hand man, and we can think of going together without communicating about many things.

"Don't you think it's strange?"

Just when we were all happy about the prospects of this serial murder case, Ren Qiushi suddenly asked a question.

We were stunned for a moment, and hurriedly cast our eyes at Ren Qiushi.

"There was no trace of a fight at the scene, how did the murderer tie the deceased to a chair? No resistance at all? Ren Qiushi looked at us and asked a very critical question.

"What do you mean......" I looked at Ren Qiushi in a daze, frowning.

"It is very likely that this was a crime committed by an acquaintance, and the deceased was controlled in an unsuspecting situation." Ren Qiushi said lightly.

"Acquaintances committing crimes? The deceased was a child trafficking criminal, and the murderer was a child trafficking parent, they are two completely hostile identities, how can they be acquaintances? Li Meng first raised his own questions.

"This is really a key point, the doors and windows are not broken, how did the murderer get into the scene of the crime?" Jiang Tingbai also pointed out a problem.
