Chapter 178 A Detailed Murder Case

After Qingming Festival, life is back on track again.

When Cen Lian came to the support squadron, he asked Yuan Chenxi and found that the city bureau had not handed over the case of the deceased person in the nursing home to them. It was probably still within the shooting range of the Xicheng branch, so their support was not needed for the time being.

Wu Qiushan came in with a lot of information. Cen Lian took a look and saw that it was the previous case in which his entire family was wiped out.

"This case has definitely been handed over to us for reopening, but as before, let's first check the files and information to see if they are of value for reopening." Wu Qiushan pointed to these things, "The case is a bit complicated, so there is a lot of information."

"I remember this case," Tang Hua remembered that they had discussed it before. "It was the case that almost made the veteran detective think it was a mutual killing caused by internal conflicts within the family, and was finally ruled murder."

Cen Lian was also very impressed by this case.

This kind of case is relatively common in major mystery novels and film and television animations, but it is very rare in real life.

The most murder cases handled by several squadrons in the Taishan branch throughout the year are either ruled out homicides or murders of passion. Those who can cover up the traces of murder are considered to have some brains among murderers. As for secret room murders and high IQ crimes, etc. This situation happens only a few times a year.

Even Cen Lian and his support squadron rarely encountered them.

"This case was initially misjudged because the murderer disguised the scene to look too much like a husband and wife killing each other," Wu Qiushan sat down on a chair. "I have read the files of this case in detail, and the only flaw found is that at the end The fruit knife the wife was holding when she died was actually unedged and did not match the marks on the dead husband’s chest.”

"What a delicate case." Forensic Doctor Lin also sat down. "The autopsy of this case was done by Mr. Bai from the Municipal Bureau. His forensic skills are very strong. Otherwise, it would be difficult to find that the shape of the wound matches the knife in the wife's hand." Not on."

Cen Lian is not worried about making such a wrong judgment.

Because if a husband and wife kill each other, there will be a criminal record above their bodies.

But judging from the photos, their heads are empty.

They are good, law-abiding citizens in the legal sense.

"This case has been under investigation around the couple's social relationship before, but it has been restarted several times to no avail." Wu Qiushan took out some information, "I'm too lazy to make a PPT. You can read it yourself."

He has already acquiesced that he is one of the support squadron's own, and has become more casual in his actions.

It just so happened that Cen Lian didn’t really want to watch the PPT.

"Good guy, this social relationship investigation has even included elementary school classmates!" Tang Hua looked through the pages and exclaimed, "Is there no result like this?"

"No," Wu Qiushan had a photographic memory and had already memorized the contents of all the information and files. "No one even had an obvious motive for the murder. Several people who had some conflicts with the couple were also investigated. All suspects can be eliminated.”

Wang Yuanteng had been looking through the files before, and finally put down the tea cup at this time.

"My impression of this case is similar," he said, having participated in the handling of this case. "I remember that I even investigated the social relationships of their children, but there were no clues. Later, the case had to be shelved."

Cen Lian suddenly felt that handing over this case to them was indeed a sign of respect for them.

"At that time, experts from the city and some provincial departments came to provide support, but they did not find any clues in terms of trace inspection, so they judged that the person who cleaned up the scene either had strong counter-reconnaissance capabilities, or was a member of our team. "Wu Qiushan looked at Cen Lian, "I have some surveillance data on this case, you can take a look first."

Cen Lian shook his head.

"According to the level of detail in this social relationship investigation, everyone who has appeared in the surveillance near his home should have been investigated. I don't think the surveillance can make any new discoveries."

If it were an ordinary case, the surveillance investigation would definitely not be so careful, but the previous investigation of this case has been so detailed that anyone who has anything to do with the couple will be investigated in detail. Anything that appeared in the surveillance, let alone Even a mosquito would have to figure out where it came from.

Cen Lian didn't think he could see anything new by watching the surveillance.

"Then where do we start the investigation?" Ququhan looked for a long time but couldn't find any clues. "This man is really good at setting up the scene. If you look at the pictures of the scene, he even did a very detailed stress analysis. , even the positions where the wife and husband fell to the ground are completely consistent with the interaction of forces."

Qu Han even specially drew a picture, "In his design, the wife and husband should have fought and then stabbed the husband in the chest with a fruit knife. When the fruit knife was pulled out, the blood traces thrown out were completely consistent with the impact of the attack." Through force analysis, the wife was stabbed into the abdomen by her husband with a saber, staggered back a few steps, fell to the ground, and died of massive bleeding."

"Is it possible that it wasn't actually a simulation?" Yuan Chenxi felt something was wrong. "Maybe he stood in front of his husband and killed her husband in the way he designed, and then stood in front of his wife and killed her again in the way he designed. Wife?"

Although it seems that this kind of operation is difficult to succeed, it is much more reasonable than if he arranged it like this after the couple died.

"Experts in the province have also made this guess," Wu Qiushan did not deny it, "They cannot rule out that the couple were killed separately, but this method of killing cannot directly point to the identity of the murderer."

"That's true," Yuan Chenxi nodded, "It's actually worthless for us to analyze the method of killing now. Although how the murderer killed people is also important, we can't tell anything from the method of killing in this case."

"I saw in the autopsy report that neither the husband nor the wife was abused, and the wife was not violated. From the behavior, it doesn't look like a revenge killing." Forensic Doctor Lin has finished reading the autopsy report, "I don't know if other experts have proposed this idea. I am more inclined to believe that this is an indiscriminate killing."

Cen Lian looked up at Forensic Doctor Lin. This was also his first thought after reading the detailed information of this case.

If it was a revenge killing, there was really no act of revenge.

Just like the case he just experienced, in order to take revenge, he knew that he might be arrested and burned someone's grave in the middle of the night.

But the murderer in this case was too calm, so calm that he didn't even think that the family of three he killed was his kind.

This is Cen Lian’s most clear feeling about this case.
