Retracing the Police Path 1993

The case reached a stalemate, and began to look back on Lao Du's contacts, from his neighbors, the former employees of the third factory, to his "tea friends" who went to the teahouse to drink tea with him every day. Although some people have already asked, Then ask again.

Liu Pengcheng knew that this was basically useless work, because it was a typical professional crime. Most people would vomit just by looking at the photo of the dead body, not to mention stabbing someone like that.The trace inspection department did not find any vomit in the stagnant water at the scene of the crime.This is a surefire career crime.Not just professional crimes, the suspect must have done major crimes and was not caught.

Professor Luo walked in, took out a thick report, and handed it to Liu Pengcheng: "Actually, the biggest feature of this case is the torture and murder of the victim. This is a detailed forensic report I made again. You can take a look."

Liu Pengcheng had just read it roughly, but before he had time to read it carefully, Director Dai called for a meeting.

This meeting was not held with the City Bureau, but a small meeting held by their crime center.

Director Dai took the position of the host and said, let's talk about it, and each has something to discover.

The first speaker was Mr. Xu, and his speech mainly had the following meanings.

First, due to the flooding upstairs, the crime scene was greatly damaged, such as very important footprints, which were not there at all.

Second, the suspect was wearing gloves all the time and was very careful. He would not touch anything in the room unless he touched it, so there were very few traces left.
Third, there were no signs of damage to the door and lock, nor were there windows, and there were no signs of climbing on the outer building, so it can be temporarily identified as an acquaintance committing the crime.Because whether you have a key or you can call to open the door in the middle of the night, you are an acquaintance.

Fourth, no murder weapon was found at the scene, and there was no trace of searching.According to the victim's daughter, Du Juan, after cleaning up the crime scene, no valuables were found missing.Robbery and homicide can be ruled out for the time being.

After listening to Mr. Xu's introduction, Liu Pengcheng's heart gradually sank, which meant that he didn't find any clues at the scene.

But he noticed one thing, that is, an acquaintance committed the crime!Liu Pengcheng had no objection to Mr. Xu's investigation, but since his home hadn't been searched and no property was found missing, he thought it was a vendetta, but he couldn't find the enemy, so Liu Pengcheng was still suspicious.

Liu Pengcheng also has no objection to professional and acquaintance crimes.

After Mr. Xu, it was Professor Luo who spoke.

Professor Luo did not read the report he gave to Liu Pengcheng, but organized it again in his own language.

Professor Luo first talked about several scars on Lao Du's body.

First, the fatal injury was a knife on the neck. The knife was very precise and directly cut through the carotid artery, but did not hurt the trachea nearby.

The second is the knife in the abdomen, which was also very precise, and cut a large horizontal cut in the abdomen, but there was no superior large intestine.Even students who graduated from medical school did not have this kind of technique just after graduation, not to mention that the victim was lying motionless on the operating table after being injected with anesthesia!
Third, the victim had knife wounds on his limbs and chest, all of which were cut out. These wounds neither hurt the bones nor opened the body. They should be for the pain of the victim. Professor Luo also agrees with Mr. Xu's point of view. It's a vendetta.

Fourth, other wounds include blow wounds on the neck. Professor Luo deduced that the victim was knocked out instantly when he opened the door for the suspect.Some of the other wounds are mostly abrasions, which should be the abrasions after the victim struggled.

Fifth, bruises on both wrists, it is highly suspected that the victim was tied up, but no rope was found at the scene.

Sixth, fibrous substances were detected in the victim's body, which was consistent with the towel left at the scene. According to Du Juan's identification, it was the victim's own towel.In other words, the victim had a towel stuffed in his mouth when he was hurt, which explains why the neighbors didn't hear them.Unfortunately, because the towel should have been thrown on the ground and soaked in water, no biological material was extracted.

Liu Pengcheng recorded these points in his notebook.

Then there was Professor Xiao, who expressed his thoughts.

He determined, yes, that there were two suspects, the first one was an acquaintance of Lao Du who could open the door for him.Old Du should have known this person for more than ten years, otherwise an old man living alone would not open the door to a new acquaintance at two or three o'clock in the middle of the night before the time of death.

This person should be a junior of an acquaintance of Lao Du, which is easy to understand. People who Lao Du has known for more than ten years must be very old, especially acquaintances who can open the door in the middle of the night.But the person who can handle this kind of case is really an old man, so it can only be the younger generation of the old man.

The second person is a recidivist. This recidivist should have been traumatized when he was young, or even physically injured or abused for a long time.Should have a decent good job, have worked in medicine, but now is not a doctor.This person is not a first-time criminal, but previous crimes should not have been exposed.

Others, because there are too few clues now, Professor Xiao still can't figure it out.

After Professor Xiao finished speaking, Mr. Qian shook his head. Now is not the time for him to play a role.

Then it was Liu Pengcheng's turn, and Liu Pengcheng still insisted that this was a Tucai case.He also talked about the results of his investigation, and everyone understood that more than one million yuan disappeared out of thin air. This is indeed a very reliable criminal motive, but if it is a case of Tucai, there are a few problems that cannot be explained.

The first question is why Lao Du was tortured and killed in the Tucai case.

Liu Pengcheng already had an answer to this question in his mind, otherwise he would not have insisted that it was a Tucai case.

Liu Pengcheng said: "Everyone just saw the result. Old Du died with scars all over his body, so he thought it was a massacre. But there are obviously two possibilities for this result, and there is another one besides the massacre!"

Professor Luo frowned, obviously a little dissatisfied with Liu Pengcheng's attempt to overthrow his conclusion: "Here are the results of the autopsy. What do you think is the possibility other than torture?"

Liu Pengcheng said: "Torture!"

Everyone suddenly realized, and asked why Liu Pengcheng had to make such a judgment that was completely inconsistent with the autopsy results!
Professor Xiao asked: "What Professor Liu means is that the suspect, like us, knows that he has the money, but he doesn't know where it is, right?"

Liu Pengcheng shook his head: "I don't think what Professor Xiao said is completely right. We know that there may be this money through deduction, and the suspect should know exactly that there is this money, and even know the exact amount of this money. However, he does not Know where it is!"

This makes perfect sense!It can only be like this!Unless there is clear news that the money does exist, and it is known how much it is, who would take the risk of losing his head to make such a big case!
Qian Lao, who had been silent all this time, asked, "Xiao Liu, you said it was Tucai, why didn't you search for it, and you didn't even lose anything at home. If it was Tucai, wouldn't it be good to take it with you?"

Liu Pengcheng also thought of this question, and he said: "First, once you get the big money, you naturally don't care about the small money. Second, people might want us to check on the vendetta!"
