At five o'clock in the afternoon of January 17, 1994, an alarm call entered the Heilongjiang Hailin City Public Security Bureau, and on the other end of the phone was a teenage girl, who heard her breathless and slightly crying voice, and at first the operator thought she was lost.
But he didn't expect that the first thing the little girl said was: "Uncle policeman, you are coming, my father is also a policeman, he has just been killed with a gun!" ”
Hearing of the extremely bad crime of killing a person and killing a policeman, combined with the girl's state, the operator immediately became suspicious of the authenticity of the case, so in order to confirm, he was ready to ask more about the details of the crime.
But before he could wait for him to speak, the little girl said more anxiously: "My father is Wang Jianmin, that is, the Hailin Public Security Bureau, I still have sisters and brothers and sisters in my family, they may not be dead, you come soon, my family lives in..."
Upon hearing Wang Jianmin's name, the operator was stunned, isn't this his colleague? He knew that Wang Jianmin's family had three or four children, and he also knew that the address the girl said was correct, so he no longer doubted at this time, and reported the situation to his superiors.
Considering that the suspect had a gun on his body, the superior dispatched a large number of police forces, contacted the hospital, sent several ambulances, and rushed to the scene with 100,000 fires.
However, unfortunately, when everyone rushed to the scene, they found that the scene of the crime was in a mess, and the blood everywhere was like a purgatory on earth, and the victim Wang Jianmin and his three children fell in a pool of blood, and many bullets on their bodies had long lost their vitality.
Seeing the tragic situation of the former colleague's family, the police officers present closed their eyes one after another, and everyone gritted their teeth and clenched their fists, secretly vowing in their hearts that they would definitely bring the murderer to justice.
Therefore, in order to solve the case as soon as possible, the police called Wang Jianmin's second daughter, the little girl who called the police, to the scene.
It was a little cruel to let a teenage girl witness the scene, but there was no way to do it, because she was the only witness at the scene, and her detailed testimony was extremely critical.
If she does not return to the scene, then the difficulty of solving the case will inevitably increase a lot. Of course, the girl herself understood this truth, so she endured the fear and sadness, but also told the police of the whole situation she saw.
According to the girl, it was dinner time that day, and her father had just made a meal and told her to go to the kitchen to get the dishes, but just then there was a knock at the door.
Wang Jianmin immediately walked over to open the door, and after opening the door, two fat and thin men walked in, and when they saw the person coming, Wang Jianmin was surprised at first, and then he smiled and said, You two are not here to rub rice, right? I just happened to be ready, let's eat some together.
Hearing Wang Jianmin's warm invitation, the two men did not refuse and immediately sat down on the sofa. When the girl heard this, she thought they were her father's friends, so she didn't care too much, but just prepared to take two more pairs of chopsticks.
However, not long after, there were suddenly two loud noises in the living room, and the girl looked at it, and it was the two people who took out guns and killed their father! Looking at the bright red blood on the ground, the girl was momentarily confused, she did not know why her father's friend wanted to kill him.
Her whole body trembled uncontrollably, but it was clear that the instinct to survive still outweighed the fear, and in order to survive, she rushed to the bathroom in three steps and made two steps, locked the door and jumped out of the window, because it was the second floor she picked up a life....
The above is the girl's entire confession about the case, from the confession the police found two key clues, one is that the two gangsters and Wang Jianmin know each other, and the relationship may be relatively good, otherwise Wang Jianmin will not leave them to eat.
Second, these two people are likely to be habitual offenders, because their modus operandi is too similar to the previous two cases of killing police and guns.
With these two clues, the police searched for traces left at the scene and instantly had a thought, holding the shell casing scattered on the ground and the mutilated fingerprints on the bathroom door handle.
The inspectors immediately returned to the police station and compared them to the two previous cases. After testing, sure enough, the shell casing and the previous "4.22" and "10.6" cases are the same model, and the fingerprints also show the same suspect.
At that time, the two cases of killing police officers and guns in 1991 and 1993, zhao Weishi and Ding Chunguo, two policemen, and their families were killed, which can be said to have caused a great sensation, and the police investigated for three years.
In addition to the shell casing and fingerprints, because there are no surviving witnesses, the police have not been able to find any other clues, but now the situation is different, in the case of Wang Jianmin's murder, there are not only witnesses, combined with the first two cases, the police investigation is much less difficult.
Therefore, in order to solve the case as soon as possible and catch these two extremely vicious gangsters, the local police immediately decided to investigate the three cases together, and once again set up a special case team to increase the intensity of the investigation.
In the detailed police investigation, an even more frightening situation has also surfaced, that is, it is not only these three similar cases that have occurred so far.
In 1993, three families close to the Chaihe City Public Security Bureau were killed consecutively, adding up, which means that these two gangsters actually committed six murders against the police, and even massacres!
Oh my God, are these two gangsters having a vendetta against the police and deliberately fighting against the local public security organs? Thinking of this, the public security cadres and policemen in charge of the case were filled with indignation, and the intensity of investigation and investigation was also strengthened several times.
Of course, it is precisely because the police attach so much importance that soon a suspect named Wang Chengyan, suspected of major crimes, surfaced.
A few hours before the police found his home, the man called a taxi and tried to escape, but not long after getting on the highway, the taxi driver saw that he had a gun in his hand, so he cleverly used the excuse of refueling to throw him at the gas station, and then chose to call the police.
In order to escape, Wang Chengyan, who could not be angry, hijacked a big bus and threatened him to drive to Kaiyuan, but he did not think that this driver was a hard bone, not only did not take him, but even the money was unwilling to hand it over.
Thinking of being teased by the driver before, and seeing this bus driver so contemptuous of himself, Wang Chengyan was immediately angry, he first brutally shot and killed the driver, and then drove away from the scene with the bus.
However, because the dispute with the bus driver delayed too much time, the police also chased after him and forced him to stop in an open area.
Seeing that he was under heavy siege, Wang Chengyan knew that his sins were deep, and he also ignored the police's persuasion and stubbornly confronted the police with a gun.
The police saw this situation, and in order not to threaten public safety, they had no choice but to send snipers to kill them. At 8:00 p.m. on January 30, 1994, Wang Chengyan was shot and killed.
After examining the gun in his hand, the police also determined that he was one of the murderers who had committed many cases of killing police and guns, but it was strange to say, why did he carry two guns alone? Isn't it hard to stop all the guilt?
This is very likely, so in order to find another gangster, the police went to Wang Chengyan's home and interrogated his family. At first, in the face of police questioning, Wang Chengyan's wife did not know what to ask, left the family clean, and denied the fact that her husband had accomplices.
However, her psychological quality is high, but it does not mean that the two children in the family are the same, so seeing that Wang Chengyan's wife refused to confess, the police changed the target of the interrogation to Wang Chengyan's son and daughter.
In the face of the police uncle, the child does not lie, so under the interrogation staff's gradual progression, the two children quickly say a few key clues.
According to their brothers and sisters, Wang Chengyan had a very good friend, a policeman surnamed Zhang, who usually called him Uncle Zhang, and just two days ago, this Uncle Zhang came to their house late at night and handed Wang Chengyan a letter, and then Wang Chengyan left home and never returned.
Hearing the words of the two children, the police also determined that this "Uncle Zhang" was another suspect, so they immediately investigated Wang Chengyan's social relations in the police station.
Through the investigation and the identification of the two children, Zhang Siwei, deputy director in charge of secretarial work of the Chaihe Forestry Public Security Bureau and a more important member of the special case team, was controlled by the police.
What the? Is the member of the task force one of the murderers? Hearing this news, the police were reluctant to believe it at first, but when they thought of the failure to arrest the murderer many times before, this time Wang Chengyan learned the news in advance and fled, all of which made sense.
In this way, the interrogation of Zhang Siwei, a member of the special case team, began, but it was obvious that Zhang Siwei, who was a policeman with extremely high anti-interrogation ability, was not so easy to deal with.
He has always behaved very calmly, that is, to avoid the important and light, saying that he and Wang Chengyan really have a good relationship, and indeed gave him a message, but this is all for the sake of brotherhood, and he himself did not participate in the murder case.
Hearing Zhang Siwei say this, the interrogators were also very helpless, after all, the tricks they used, he Zhang Siwei knew it, so in desperation, with the permission of his superiors, the interrogators had to deceive Zhang Siwei.
They said that Wang Chengyan was actually not dead, just seriously injured, before the police considered that there may be internal problems, has not been public, but now that he has woken up, he does not have such a great ability to survive the interrogation, so I hope Zhang Siwei still has a good account as soon as possible, and there is a chance to get leniency.
Hearing that Wang Chengyan was not dead, Zhang Siwei was suddenly shocked, and the originally impregnable psychological defense line also appeared in an instant, coupled with the police searched for a series of physical evidence from his home, and soon Zhang Siwei confessed the truth of everything.
According to Zhang Siwei, the reason why they chose to kill the police was actually because they wanted to use the principle of "black under the lights" to rob these belongings, after all, Zhang Siwei is a policeman, and Wang Chengyan's identity is also relatively special.
If Wang Jianmin's daughter did not survive, no one would suspect them at all, and even if they did, Zhang Siwei himself would be in the task force, and they would most likely not be caught by taking advantage of this...
At this point, with the death of Wang Chengyan and Zhang Siwei's confession to his criminal process, and finally severely punished by the law, these six consecutive cases, killing seventeen people in succession, also officially came to an end.
