The case reached an impasse, and he began to look back at Lao Du's connections, from his neighbor, the original employee of the third factory, to the "tea friend" who went to the teahouse every day to drink tea with him, although some people had already asked, then ask again.

Liu Pengcheng knew that this was basically useless, because this was a typical professional crime, and ordinary people didn't need to say that they stabbed people with knives to look like that, even if they looked at the photos of the corpses, they could vomit at a glance. However, the trace examination department did not find any vomit in the stagnant water at the scene of the crime. This is a well-established professional crime. It's not just professional crimes, the suspect must have done big crimes and was not caught.

Professor Luo walked in, took out a thick report, and handed it to Liu Pengcheng: "In fact, the biggest feature of this case is the torture and murder of the victim, this is a detailed forensic report I have redone, you can take a look." ”

Liu Pengcheng just read it roughly, but before he had time to read it carefully, Director Dai notified the 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, what have you discovered.

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

First, due to the water from the upper floor, the crime scene was greatly damaged, such as very important footprints, which were not at all.

Second, the suspect wore gloves throughout the whole process and was very careful, and he didn't touch everything in the room if he could, so there were very few traces left.

Third, there are no traces of damage to the doors and locks, nor are the windows, and there are no traces of climbing in the outer building, so it can be temporarily characterized as an acquaintance committing the crime. Because whether it is a key or a person who can open the door in the middle of the night, they are acquaintances.

Fourth, no murder weapon was found at the scene, and there were no traces of rummaging. According to the victim's daughter, Du Juan, after cleaning up the scene of the crime, no valuables were found. For the time being, robbery and homicide can be ruled out.

After listening to Xu Lao'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, and that was that acquaintances committed crimes! Liu Pengcheng had no objection to Xu Lao's investigation, but the house was not rummaged through and the property was not lost, so it was considered a vendetta, but he couldn't find the enemy, and this Liu Pengcheng was still suspicious.

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

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 words.

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

First, the fatal wound is a knife in the neck, which is very accurate, directly cutting the carotid artery, but not injuring the trachea on the side.

Second, it is the knife in the abdomen, which is also very accurate, cutting a large hole horizontally in the abdomen, but there is no superior large intestine. Even a student who graduated from medical school, he didn't have this method after graduation, not to mention that the victim was not lying motionless on the operating table with anesthetic!

Third, the victim's limbs and chest all had knife wounds, all of which were scratched, and these injuries did not hurt the bones or disembowel, which should be to make the victim painful, Professor Luo also agreed with Xu Lao's point of view, this is a vendetta.

Fourth, other wounds included a blow wound to the neck, which Professor Lowe deduced was an instant knockout of the victim when he opened the door to the suspect. Some of the other wounds were mostly abrasions, which were supposed to be abrasions after the victim struggled.

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

Sixth, fibrous substances were detected in the victim's mouth, which was consistent with the towel left at the scene, which was identified by the cuckoo as the victim's own towel. In other words, the victim had a towel in his mouth when he was hurting, which explains why the neighbors didn't hear them. Unfortunately, because the towel should have been thrown on the ground and blistered, no biological samples were extracted.

Liu Pengcheng recorded these points in his notebook.

Then there was Professor Shaw, and Professor Shaw said what he thought.

He decided, yes, that the suspects were two people, the first person was Lao Du's acquaintance, the acquaintance who could open the door for him. This person Lao Du should have known him for more than ten years, otherwise an old man who lives alone will 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 the younger generation of an acquaintance of Lao Du, this is easy to understand, Lao Du has known people for more than ten years, and they are all older, especially acquaintances who can open the door in the middle of the night. But the person who can do this kind of case is really enough to choke the old man, so he can only be the younger generation of the old man.

The second person is a repeat offender, and this repeat offender should have been traumatized at an early age, or even physically harmed or abused for a long time. There should be a decent good job, having worked in medicine, but now the profession is not a doctor. This person is not the first time he has committed a crime, but previous crimes should not have been exposed.

For the rest, because there are too few clues now, Professor Xiao can't judge it.

After Professor Xiao finished speaking, Qian Lao 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 case of seeking wealth. He also talked about the results of his investigation, and everyone understood that more than one million was gone out of thin air, which was indeed a very reliable criminal motive, but if it was a case of seeking money, there were a few problems that could not be explained.

The first question is why Lao Du was tortured and killed in the case of trying to make money.

Liu Pengcheng already has an answer to this question in his heart, otherwise he would not insist that it is a case of seeking money.

Liu Pengcheng said: "Everyone just saw the result, Lao Du died with a scar, and thought it was torture and killing, but there are obviously two possibilities for this result, in addition to torture and killing!" ”

Professor Luo frowned, obviously dissatisfied with Liu Pengcheng's conclusion that he wanted to overturn him: "The results of the autopsy are here, what other possibilities do you say besides torture and killing?" ”

Liu Pengcheng said: "Torture! ”

Everyone suddenly realized, and said why did Liu Pengcheng have to make such a judgment that was completely inconsistent with the results of the autopsy!

Professor Xiao asked, "What Professor Liu means is that the suspect, like us, knows that there is this money, but does not know where it is, right?" ”

Liu Pengcheng shook his head: "I don't think what Professor Xiao said is entirely right, we know that there may be this money by inference, and the suspect should know exactly that there is this money, and even know the exact number of this money, but he doesn't know where it is!" ”

It makes perfect sense! And so it can only be! Unless there is clear information that the money does exist, and it is known how much money it is, who would risk losing their heads to make such a big case!

Qian Lao, who had not spoken, asked: "Xiaoliu, you said that this is a fortune, why didn't you rummage, and you didn't even lose anything at home, if it was a fortune, wouldn't it be good to take the sheep with you?"

Liu Pengcheng also thought of this question, and he said: "The first one, when the big money is in hand, naturally I don't care about the small money, and the second one, people may want us to check on the vendetta!" ”
