"At half past eight o'clock in the evening of October 21, an eight-year-old boy was strangled to death in Hongbin Community of our city, before his death, the boy went downstairs to help the family throw garbage, and the body was found by his family at 8:45, the location is at the head of Building No. 8 in the community, here is a dead corner of the community, Building No. 8 is also the last building in the community, this community is an old community, there is no back door, there are eight buildings here, there are eight buildings on the other side of the road, there is an exit from the front door, there are walls on three sides, and the front is an iron fence and gate."

"At 8:40 p.m. on October 24, a nine-year-old girl was strangled to death in my citizen and Li community, this girl was killed on the way back to her home from her grandmother's house in the same community, that is to say, the victim's home and grandmother's house were in the same community, and the place where the body was found was on the first floor of her own building, and the time when the body was found was 8:45, which was estimated by us based on the time said by the victim's parents and grandmother, and when the victim left the grandmother's house, the grandmother sent a message to the victim's father. The victim's parents waited at home for five minutes, but when they did not see the child come up, the victim's father put on his coat and went downstairs to find the body. ”

"October 30, that is, last night, in our city's Jiashui Liyuan Community, a seven-year-old boy was stabbed to death, five stabs in the body, the time of death was half past seven, the child was killed when he was playing in the community, but the time to find the body was 8:20, the place where the body was found was a perennial park in the community has not moved under the van, at that time other children went home to eat, only he was still playing."

"The three murders occurred in the community is not close, not even in a district, the scene where the body was found because of the emotional problems of the child's family, plus the crowd of onlookers, the damage was very serious, when the police arrived, the children were in the arms of the parents, and again, the mouths of the three murdered children were blocked with scotch tape, and the family members uncovered them before the police arrived, and the fingerprints on them were very messy. You can see from the photos that the three crime communities are relatively old communities, all of which are five- or six-story slab buildings, and there is only monitoring at the gate of the community, in fact, if you want to enter the community, you may not necessarily go to the main gate, it is easier to climb over the wall, this is just an inference from us, because when the three cases came out of the scene, they all called up the surveillance, and no suspicious people or cars were found before and after the incident. ”

"Furthermore, the murderers in the three cases had different methods of killing, but it can be determined that it was a serial child murder case, because a small car toy was found at each scene that was exactly the same but of a different color, and I deduced that it should be placed next to the child's body, because the body was found by the relatives of the murdered child, and it was night, and when we found it, there were cars everywhere, and another was trampled."

"In addition, no other clues were found, the footprints at the scene were chaotic, oh, by the way, the child killed last night was stabbed to death and dragged under the car, there were traces of blood at the scene, but when the police arrived, it was almost destroyed, too many residents of the community gathered at the scene of the crime before the police arrived, and the trace examination failed to find any useful clues or evidence at the scene."

After Zhao Xueming finished speaking, he looked at the leader, and the leader said with a serious expression:

"I won't say much about the consequences and impact of the serial child murder case, most of you are already fathers, and you will compare your hearts with your hearts! Our duty is to protect the safety of people's lives and property, but now the murderers are acting recklessly under our noses! Three children have already been killed, and we must not allow another tragedy to happen! That's the bottom line! I don't say anything about solving the case within a time limit, I believe that you will never let the murderer go unpunished, and will do everything possible to arrest the murderer as soon as possible! Before the case is solved, I won't go anywhere, this conference room was requisitioned by me, this is our 1021 Serial Child Murder Case Task Force Office, you guys are busy, once there are some clues, let's focus on analyzing the case here! Don't waste time, you start the work as soon as possible, Zhao Xueming, you take them to their respective offices, how you need your city bureau to cooperate, how you need to cooperate, now everything is on the premise of preventing the murderer from committing crimes again, and everything else will give way! ”

Zhao Xueming nodded heavily.

……

The people from the technical department of the provincial department were directly taken to the technical department of the Liaobin City Bureau, and they also brought equipment from the provincial department, and the people from the technical department of the Liaobin City Bureau helped move to the office.

Zhou Wang, Dalong and Zhang Heng followed Hu Yang to an office, Hu Yang asked everyone to sit casually, and then went straight to the topic:

"I know you're all having a hard time driving here, get over it! You have all read the autopsy reports of the three murdered children, the cause of death is not complicated, wait a minute, let's do an autopsy for the three murdered children together, with questions, when the autopsy is completed, let's find the answer together, the first question, why did the murderer do it three times, but used three ways to kill? The second question is, did the murderer abuse the child before he committed it? The third question, how did the murderer fail to make the child scream, I mean before sealing the child's mouth with scotch tape, how to prevent the child from shouting, just by covering his mouth? Fourth, what did the murderer bring? These four questions, you keep in mind, let's re-autopsy now! ”

……

Zhou Wang made up these four problems in his mind, and found that if this problem was solved, basically the process of the murderer's murder would come out, and if he thought about it deeply, it was possible that even the murderer could be pushed out.

Zhou Wangxin thought and learned another trick.

During the autopsy, Hu Yang personally performed the autopsy, and Zhou Wang watched carefully with wide eyes.

The children have different bumps and bruises on their bodies, but they are all daily old injuries, children are naughty, and their bodies are often blue and purple, except for them, they have not found new injuries in poplars.

Every time the autopsy of a murdered child was completed, Zhou Wang's heart felt like he had been pierced by something, and the elf who should have been alive, who should have lived under the wings of his parents, was now lying on the cold dissecting table.

The autopsy was completed quickly, which also shows that the cause of the child's death is relatively single, only the autopsy of the third victim took some time, and the victim was stabbed five times, of different depths, and only one knife was fatal.

The conclusion of this autopsy is consistent with the results of previous autopsies by the forensic doctors of the Liaobin Municipal Bureau, who have not been able to find new clues.

A few people returned to the office, and Hu Yang asked before he sat down: "Zhang Heng, tell me first, is there an answer to the four questions just now?" ”
