Profiler 4: Criminal Investigation Team

"Why am I so nervous..."

Liu Yunli blurted out: "Leader, I have to go home and cook for my grandson!"

After Liu Yunli finished speaking, she left in a hurry without waiting for their answer.

Jiao Yang looked at Liu Yunli's back, and said thoughtfully, "This eldest sister's reaction is a bit strange."

A township cadre accompanying the town smiled and said, "Captain Jiao, you can't blame her. Zhang Guangchao was arrested after the case came out. His parents died early, and he is an only child. There is no one at home, and he has never been. Married. He was arrested and imprisoned at a young age. This man is usually a good person. Some people in our town can’t believe that he can kill people. He even killed four people in a row. He was very pitiful. I went to testify Those few, sometimes there are some gossips in the village, saying that they are talking nonsense in order to get bonuses."

Jiao Yang asked in surprise, "Bonus?"

The township cadres realized that he might have said something wrong, and quickly laughed: "No, no, it's just rumors in the village!"

In the last century, especially in the 90s and [-]s, in order to solve crimes, there were indeed some chaos among individual personnel in certain places.

Jiao Yang did not expect that Director Ke also had such a rumor.

To be honest, there is evidence for Zhang Guangchao's involvement in this case, but it is not hard enough.In particular, part of the most critical murder weapon was not found, let alone Zhang Guangchao's body//fluids were not found on the victim.

If it is now, the procuratorate will at least remand the case for retrial, ask the public security department to add evidence, and may even release the suspect in court.

At present, the internationally prevailing judicial spirit is never to suspect, and so is our country.But in terms of actual implementation, more than ten or twenty years ago, the country was based on the principle of mitigating the crime on suspicion, rather than never suspecting it.For example, Zhang Guangchao was sentenced to death with a reprieve, but later because of his major meritorious service, it was changed to 20 years in prison, and he will be released soon.

Because in our country, traditionally, the judicial spirit has paid more attention to not to be wronged, not to be indulged, and to strive for precision.After all, no doubt is a very broad concept.There are very few cases where 100% doubts can be found in any case.It can even be said that there is no doubt. As long as the relevant personnel are skilled enough, doubts can be found no matter what.Then the question arises, how much doubt is there, and where is no doubt?In terms of specific implementation, if there is a slight error, it may indulge a large number of criminals and become a hotbed for high-IQ crimes.

When I came back for a meeting at night, Jiao Yang said: "I think there is something wrong with this Liu Yunli. Although what the town officials said is natural, I feel that when Liu Yunli faced us, her eyes flickered and her expression was very nervous. You can contact the local police. Look up her experience, and then find out with the local residents, whether she has any connection or interest with the two parties in the case."

Hou Xiyong smiled and said, "Boss, you don't think it was this Liu Yunli who killed Li Miaomiao, she was a woman. The murderer has sexually assaulted her, so of course she has to be someone in charge!"

"Liu Yunli will not be the murderer."

Jiao Yang shook his head and said, "I just have a different feeling. As you all know, I seldom use the so-called sixth sense to solve cases. However, if Zhang Guangchao was really wronged, to prove that he did not commit a crime, he must Starting from two points, the first is to find the proof of his time on the night of the crime, and the second is to find the real culprit.

However, 20 years have passed, not to mention that this place should not have been monitored at that time, even if there was, the physical evidence has long since disappeared.Two people who often fished with Zhang Guangchao at that time had no impression of him, and some of them had already passed away.It is difficult to prove from this point.If Liu Yunli is really hiding something, then follow her to find out the real culprit. "

Yu Xiaoguang said: "Boss, what if Zhang Guangchao is really the murderer? After all, he lied about extorting a confession by torture. Although he will be released from prison soon, according to the investigation, he is the only one in his family. After he came out , Life is a problem. If he can prove that he was wronged, he can get a large amount of state compensation. I think he still has a certain motive to lie."

"I've also thought about this possibility."

Jiao Yang said: "We are only responsible for reviewing the case, not saying that it must be overturned. But on the other hand, after 20 years, it is basically an impossible task for us to find strong evidence to prove that Zhang Guangchao is the murderer."

Yu Xiaoguang first took a copy of Liu Yunli's household registration and some documents from the local police.

Liu Yunli's experience is very simple. After entering junior high school, she did not go to further education. After inheriting her father's mantle, she got married and had children after working in a local parts factory for a few years.

Jiao Yang sat in the office temporarily arranged for him by the Chongming District Bureau and thought about it, but he couldn't think of any solution. After 20 years, three of the several crime locations no longer existed.The other one was changed to a farmer's market, and it was impossible to find any evidence.

Hou Xiyong crossed Erlang's legs and said, "Boss, what are you worried about? Wouldn't it be better not to overturn the case? That's Ke Ju. Let me tell you, the overturn of the case will be fatal!"

Jiao Yang said in a deep voice: "But now I can basically be sure that Zhang Guangchao is not the murderer. Even if it is not to pay him justice, there are still four young lives who died innocently, waiting for us to avenge them!"

However, thinking about it alone is not the solution.Jiao Yang called the people in the office and held a temporary video conference.Of course, it also includes Professor Lu who is in Dongzheng University at this time.

Lu Yuanli read the latest dossier, thought for a while and said, "If you all feel that Zhang Guangchao is not the real murderer, we might as well assume that he was wronged. Then, how did his fingerprints get on the victim's head?" What about the black plastic bag?"

Jiao Yang said: "Actually, I have been thinking about this problem too. You see, in the first three cases, no fingerprints were found on the plastic bag on the victim's head. Only in the fourth case, the dead woman Li Miaomiao was found on the plastic bag on the head. , found two fingerprints of Zhang Guangchao.

This place, I always think it is unreasonable, the murderer should become more proficient in committing crimes, it is unreasonable that the fingerprints mixed with fish blood on the hand are relatively obvious, to the extent that they cannot be seen.

In my opinion, this is likely to be a deliberate frame-up.Since the real murderer committed three cases in a row and aroused public outrage, the police in Chongming District pursued him day and night. When the murderer was in panic all day long, he found Zhang Guangchao's fingerprints on the handle of the plastic bag, and deliberately chose him as his scapegoat.

Therefore, the question that Professor Lu just mentioned should be divided into two parts. First, why are Zhang Guangchao's fingerprints on the plastic bag?Second, how did it get on the plastic bag?These are actually two concepts.However, as I mentioned just now, in the dossier, Zhang Guangchao is a fishmonger who makes a living as a fishmonger.Therefore, after he kills the fish, he puts it in a plastic bag and hands it to the customer and buyer. It is normal behavior that the fingerprint is on the handle. "

Ke Luoluo bit his lip, couldn't help raising his hand and said, "Then why is there no second person's fingerprint on this plastic bag? The fourth case was committed on September 2001, 9. If you just said The establishment, the murderer must get this plastic bag before September 15th.

I checked and it was a particularly hot summer that year.It's still very hot in autumn. Wouldn't it be strange if someone wears gloves to buy fish?Why did the police repeatedly ask Zhang Guangchao if there was anything special? Even if the confession was retracted in court, when life and death were at stake, he didn't mention it? ! "

Jiao Yang said: "I've thought about this question too, and I think there are three possibilities. First, Zhang Guangchao is an ordinary villager with a low level of education. He may not have imagined that when a customer came to buy fish, his fingerprints would show up at the scene of the crime. The connection in the evidence. Second, people generally like to get up early to buy fresh food. There may be a lot of people in the farmer's market in an instant. Zhang Guangchao is busy selling fish and killing fish, so he may not be able to notice. Third, there is a situation where it is normal to wear gloves in hot weather, and most people will not notice the difference at all. That is, many people like to wear gloves when riding electric vehicles. 20 years ago, electric vehicles It is a very common means of transportation in Chongming District.”

Li Shen coughed and said: "So, the real culprit is very likely to be one of Zhang Guangchao's customers who came to buy fish back then. Moreover, the farmer's market where Zhang Guangchao is located is not well-known, so the real culprit should live near there."

"But what's the use of knowing that?"

Ke Luoluo said: "I read in the file that this Zhang Guangchao has been fishing and selling fish with his uncle since he was not yet an adult. When the case was filed, he has been in this business for more than 10 years. Even if there are dozens of customers every day, Isn’t so many years an astronomical figure?!”

"That's not the case, Xiao Ke, didn't you listen to what Team Li said just now? The farmer's market where Zhang Guangchao is located is not famous, and the people who come to buy things are people nearby. It is very likely that Zhang Guangchao sells 100 fish every day, and five or sixty people are the same of."

He can understand Ke Luoluo's mood, but the truth is another matter.Jiao Yang said: "Let's look at the situation in Chongming District back then. The place was not too big, and the people were familiar. There were three consecutive rape/murder cases. People in the society were panicked, and rumors were raging. The suspect was a fishmonger. The fish is a business, and there are details such as a blue pickup truck, which are likely to have spread.

To consider using Zhang Guangchao as a scapegoat, at least someone who knows him, or even Zhang Guangchao's neighbors or acquaintances, has a clear understanding of his work and rest patterns and vehicle conditions! "

Ke Luoluo couldn't help but rolled his eyes and said, "Even so, there are tens of thousands of people in that town, so it's still useless!"

Jiao Yang calmly said: "Then we can also start from the villagers near Zhang Guangchao at that time, and gradually extend to the town. Also, this is from Zhang Guangchao's perspective, considering the connection between the murderer and him, we can also change the angle, from The four victims came to ponder what happened to the killer."

Lu Yuanli said: "This is actually the traditional point of view, and we usually analyze it from this direction first. Regardless of whether it is international or domestic, sexual/assault cases, regardless of gender, the vast majority of victims are victims of their elders, relatives and friends. Violations by acquaintances. But the four victims in this series of cases did not know each other, so the police at that time solved it with a series of indiscriminate attacks."
