Profiler 4: Criminal Investigation Team

Recently, after more than ten years of relentless appeals, the parties involved in a murder case in a certain place were acquitted and acquitted. There was a wave of reversal of the case on the Internet.In many cases that were filed several years ago, more than ten years ago, or even decades ago, the perpetrators or their family members applied for reconsideration.

This time, the public security bureaus in many places became lively.

After the meeting yesterday morning, Deputy Director Wang called Jiao Yang and Li Shen into the office.

"The King's Bureau."

Jiao Yang greeted Director Wang, and saw Li Shen already sitting there.

"Jiao Yang, you handled the last case well, sit down."

Deputy Director Wang took a sip of tea slowly, "Recent public opinion, you may have noticed that there are many cases applying for reconsideration. On our side, we also received a dossier from the Supreme People's Procuratorate. Li Shen has already read it , take a look too."

Jiao Yang took the file, opened it and looked through it quickly, and saw that it was a rape/murder case many years ago.

One morning in the autumn of 2001, Li XX, a high school girl from Chongming No. [-] Middle School, was found dead behind a bush.

Li Moumou suspected that he had been raped before his death, and then he was hit on the head with a heavy object such as bricks and stones, causing his head to bleed, and then he was strangled to death with a rope.When the body was found, Li Moumou had a black plastic bag covering his head.

There is blood-like substance on the outside of the plastic bag, and complex and difficult symbols are painted on it.This situation immediately attracted the attention of the police.

Because prior to this, three such cases occurred in Chongming in April, June and August of that year. Three young girls aged 4 to 6 were killed. Serious panic.

After being played up by the media, all kinds of rumors spread everywhere. Some said that a fugitive escaped from prison and committed crimes. Some said that this was a resentful female ghost who died unjustly and came out to find a substitute. Some said that a cult murdered and sacrificed with CN's blood. The more chaotic.Many young girls dare not even go to school alone, and are picked up by their parents.

Since the first case appeared, the Chongming police have been under tremendous pressure.In particular, the cases followed one after another, and the tactics and performance were consistent. They could basically be identified as the same series of cases. After the murderer was also identified as the same person by the local police and criminal investigation experts, the Chongming police received a strict order from the city to solve the case within a one-month deadline.

However, the case was full of difficulties. Although it was a sexual/homicide case, the murderer did not leave semen/spots, body/fluids and other substances on the victim, nor did he find key evidence such as fingerprints and blood that could prove the identity of the murderer.

Of course, there is no evidence, but it cannot be said that there is no evidence at all.But the main thing was the black plastic bag that covered the faces of the three dead.

The police in charge of the case had repeatedly checked back and forth, and found that the three plastic bags left at the crime scene had no printed words on the inside or outside, that is, they did not have any characteristics of their own.

After inspection, this black plastic bag made of recycled plastic is mainly used as a garbage bag.But there are also many street vendors who use them as shopping bags to hold items that are not directly imported.Every plastic product factory sells a huge amount of such products, and the products are similar, so it can be said that they have no characteristics at all, and they cannot be traced.

As for the blood stains left on the surface of the black plastic bag, after forensic examination and trace inspection, apart from a small amount of blood left by the victim, the handwriting like symbols on it is not human blood, but fish blood, which belongs to certain marine fish.

In addition, on August 2001, 8, the day before the discovery of the deceased in the third case, near Lingzhuang Village, where the body was dumped, witnesses saw a dark blue van passing by, but No license plate was seen.

From this, the police handling the case analyzed that the murderer may be a fisherman or a fish and shrimp dealer. Such a person is easily exposed to fish blood. The purpose of buying a small truck is to deliver goods more quickly and ensure the freshness of seafood products.

However, Chongming is surrounded by the sea on all sides, and many of the local young and middle-aged laborers were born in fish farming ponds and fishmongers. It is difficult to further identify the suspects and narrow the circle.

At that time, the criminal investigation team leader of Chongming District, who was in charge of the case, connected the three places where the three deceased were found, and used them as the central area to carry out a blanket search to investigate the suspects.

Although the occurrence of the fourth case made the police officers very distressed, it also gave them one more chance to capture this blood-debt murderer.

Because Weizhuang Village, where the No. 4 deceased was found this time, is in this key area.

According to the family members of the deceased Li XX, the girl did not return home the night before, and the parents have called the police.The next morning, the students passed by on their way to school and called the police after finding Li's body.

The Chongming police quickly dispatched the police after receiving the report. In addition to the body of the deceased, they also found the victim's scattered schoolbags, books, clothes and water bottles at the scene.

There were new lacerations on the vagina of the deceased, and the forensic doctor determined that the deceased had been raped/exploded during his lifetime.However, no DNA substances such as Jing//Madara were found, and the hemp rope and bricks used as the murder weapon were not found at the scene.

However, in addition to the victim and the two girls who found the body, the footprints of the fourth and fifth persons were also found at the scene.At the same time, the fingerprints of the deceased and another person were found on the deceased's kettle.

After inspection, the fingerprints and one of the footprints belonged to Zhang Guangchao, a villager in the village.Police dogs were also at the scene and recognized the breath left by Zhang Guangchao.

Then, trace inspection carefully found a more exciting evidence, that is, several incomplete fingerprints were found on the handle of the plastic bag.

The police suspected that there were heavy objects in the black plastic bag, which caused the plastic bag of average quality and thin texture to be pulled and deformed, resulting in incomplete fingerprints.

After working overtime for two days, the two trace inspectors finally put together a complete fingerprint.It turned out that these fingerprints were consistent with the fingerprints found on the girl's water bottle, and belonged to Zhang Guangchao, a villager in Weizhuang Village.

Immediately afterwards, the police handling the case found a hemp rope in the utility room in the backyard of Zhang Guangchao's house.

After inspection, the forensic doctor extracted a small amount of skin tissue from the hemp rope and found the DNA belonging to the No. 4 deceased Li XX.The forensic doctor determined that this hemp rope was the murder weapon that finally strangled Li XX.

At the same time, after investigation, the police found that Zhang Guangchao and the family of the deceased Li Moumou were villagers from the same village, and the two families were not far away.The father of the deceased Li Moumou fished for a living and often went to sea. Zhang Guangchao had a long-term improper relationship with Li Moumou's mother Chen Moumou.After being discovered by the deceased's father, Chen Moumou broke up with him, and Zhang Guangchao was beaten by the deceased's father Li Mouyang. Zhang Guangchao threatened to retaliate with the villagers of the same village many times, and he was suspected of committing a major crime.

Therefore, Zhang Guangchao was identified as a suspect in the case by the police.

After Zhang Guangchao was arrested, he confessed that after he came back from fishing, he found the victim Li Moumou who was coming home from school alone, so he had evil thoughts, dragged her into the bushes and raped her, because the victim saw his face when he resisted, He feared the crime and killed him.

However, the defendant Zhang Guangchao later retracted his confession in court, claiming that he was tortured by the police, and that the confession was torture.

However, that was Shencheng at the beginning of the 21st century, and the legal system was relatively sound.What's more, the society attaches great importance to such a case, and it is impossible for the police handling the case to act arbitrarily.Afterwards, the Shencheng Procuratorate sent an investigation team composed of many people to review the interrogation video, but did not find that the police officers in the case had tortured to extract a confession.

Ordinarily, this kind of case of killing four people in a row should sentence the criminal to death, but because of the seriousness of the case, there are considerable doubts.For example, none of the four victims could find body/fluid, blood and other substances belonging to Zhang Guangchao, and only the murder weapon that strangled the deceased Li XX was found, and the murder weapon in the first three cases was missing.Therefore, under tremendous pressure, the judge handling the case finally ruled that Zhang Guangchao was guilty of rape and homicide, and his death sentence was suspended for two years.

However, the suspended death sentence in such vicious cases is also for further investigation and evidence collection, and to improve information. Most of the perpetrators still have to execute the death penalty.

There is no such thing as an amnesty in my country's socialist society, so why was Zhang Guangchao able to survive?Because he had an extremely important meritorious service afterwards.

After the verdict, Zhang Guangchao was assigned to a prison in the border area because he was a serious criminal.

Just in time for a certain sensitive period, the prison was infiltrated by some foreign forces, cooperating with some heavy traffickers in the prison, trying to violently resist the law and escape collectively.

Zhang Guangchao is a felon who will be shot, and he often calls for injustice, so he has naturally become an object that some people can win over.

After Zhang Guangchao learned the news, he immediately pretended to agree, and tried his best to inform the prison guards without alerting the criminals who were trying to escape, and cooperated with the prison to defeat this major conspiracy.

Therefore, Zhang Guangchao's sentence was commuted to life imprisonment for his great meritorious service. Later, after several commutations, he will be released from prison soon this year.

In the two or three years since the verdict was executed, Zhang Guangchao and his family had filed appeals or administrative reconsideration many times, and the Shanghai High Procuratorate upheld the original verdict.Unexpectedly, many years later, when he was about to be released after serving his sentence, Zhang Guangchao proposed to reverse the case again.

Wang Zhong said slowly: "It is the legal right of criminal suspects to file appeals or complaints. With the gradual improvement of the rule of law in our country and the law enforcement becoming more and more humane, such complaints may become more and more serious within a certain period of time. Many, but will gradually disappear.

In the past, most of these cases would be remanded for retrial, but with the lapse of many years, the criminal police have been transferred from the original unit, or even retired. There are more and more cases. All localities tend to assign special personnel to take charge, so as not to appear, athletes When you are a referee yourself, and engage in malpractice for personal gain.How about this case, which one of you has the confidence to do a review? "

Li Shen hesitated for a while and said: "Director Wang, our team has just taken over a special witness protection job, which requires a lot of people, and we may not be able to spare for a while, so we can deal with the administrative review case."

Obedient and listening, Jiao Yang said: "Then I will come."

Wang Ju put down his cup, looked at him, stretched out his hand, and patted the file meaningfully, "Jiao Yang, I know you have experience in this area. But you must handle this case with caution." !"

Jiao Yang nodded and said: "Wang Ju, don't worry. Every case is related to the vital interests of the people, especially this kind of administrative reconsideration case, most of which involve the blood and tears of one or even several families. Needless to say, I will It will be taken seriously!"
