A Professional Assassin - Chapter 52

Lin Yuetian drove to the police station to attend the task force meeting. The system made a lot of comments on this picture, such as “the weasel greets the chicken in the New Year”, Lin Yuetian thought that his language skills were not good.

The leader of the task force, Chen Chen, had been waiting for him for a long time. Chen Chen was in his 40s this year. He had been with the original colleague many times before, and the two were considered friends. He had heard of a bunch of bad things that Lin Yuetian had encountered recently, and came up to pat him on the shoulder first: “It’s a good thing to have pressure, but Xiaolin, don’t be too burdened.”

“I’m fine, Captain Chen,” Lin Yuetian pulled out his chair and sat down, took out the dossier and notes, “Captain Chen, let’s start now.”

Chen Chen nodded, and then said to the other police colleagues: “Okay, the tenth special meeting on the 427 blunt weapon serial murder case officially begins now.”

He clicked on the computer, showed the PPT on the projector, and reviewed the case at the same time: “The first victim of the April 27 serial murder case is Zhao Fanyun, who lives alone and is a freelancer. On April 27, the day of the incident, the victim had a morning Running habit, he went out for a morning run around the community at 5:00 in the morning, and then went to buy breakfast outside the community at 5:20. Later, the victim walked through this alley to go home. It was 5:40 in the morning. , he met the murderer, and was hit on the head with a blunt object by the murderer to death, and was later found by sanitation workers at noon. The autopsy determined that the murder weapon should be a claw hammer. We searched hardware stores across the city and found no crime. In the first three months, there were suspicious people enough to buy claw hammers. There were no footprints, fingerprints, DNA, or hair left at the scene. The victim lived in a relatively remote place. This alley was usually empty, and no witnesses were found. “

PPT switched to the second one. Chen Chen continued to introduce: “Starting with the second victim, the prisoner began to commit murders on rainy nights. The second victim was He Dan, who was in the clothing business and had complicated interpersonal relationships. He had the habit of going to the reservoir to fish. He Dan had a phone call with his wife at eight o’clock in the evening, two hours before the incident. He Dan mentioned that it was starting to rain, so he brought a raincoat by himself. My wife called the police and found it the next day. It was also a blunt force injury. This time the murder weapon was a rock near the reservoir… Please see this, the murder weapon was found this time, but there was no information. Due to the heavy rain, the scene was destroyed serious.”

“The next deceased are male and female,” Chen Chen quickly introduced, “We have investigated the interpersonal relationships of the five deceased, and we have not found any intersection, nor have we found anyone who may have murderous intentions against them. The only one. The common point is that there are no clues at the scene. All five people died of blunt weapons. However, the injury identification of the last three deceased people shows that the murder weapon in the last three cases should be a masonry hammer. However, this does not mean that the murderer is a construction site worker or the like. , after all, our city’s construction sites are generally not strict with tools, and it is not ruled out that the murderer may steal. Xiao Xie from our group made a profile of the murderer, and I printed it out for everyone to see. “

Chen Chen handed out a stack of printer paper. Lin Yuetian took over to read, and the content was not particularly large: young and middle-aged men, age may range from 20 to 45, strong anti-reconnaissance ability, may have a criminal record, random murder, anti-social tendencies, and may be sensitive to rain or blunt weapons special feelings.

Chen Chen stared at Lin Yuetian, who had never expressed his opinion: “Detective Lin, do you have any ideas?”

Lin Yuetian repeated a content in the profile: “The prisoner’s anti-reconnaissance awareness is very strong, I think he may have a criminal record.”

“We’ve thought about it for a long time,” Chen Chen said helplessly, “We have investigated all cases of blunt weapon wounding or homicide in this city and the three nearby cities in the past two years, but the prisoners in all cases have already been arrested and are in the bureau. They have no ability to commit crimes. We even checked their close relatives, and we didn’t find any suspects who had time to commit crimes five times.”

“That’s not what I meant,” Lin Yuetian explained, “Why do you think the murderer chose to commit the crime in the rain?”

“It’s convenient to hide traces.” Chen Chen replied.

“Yes, but there is still a problem,” Lin Yuetian pointed at the file, “The first victim, Zhao Fanyun who died in the alley, didn’t die in the rain, right? He died in the early morning and came out for morning training. .”

“You can hide traces in the early morning. There are few people in the early morning, and it is not easy to have witnesses.”

“That’s right, but the first time the prisoner chose to commit the crime in the early morning, why did he give up this idea and choose a rainy day again?” Lin Yuetian said to himself, “I put myself in my shoes and thought about it. It’s because rain is more convenient than early morning, and what’s the most convenient thing about rainy days… rain, scouring — it’s blood.”

“Why bloodstain.” The system spoke in a tone that couldn’t understand you perverts.

“Because some people wear raincoats on rainy days.” Lin Yuetian pointed to Chen Chen, and was actually explaining to the system, “The most difficult clue to deal with in a murder case is the bloodstain, and the most difficult bloodstain is at the scene, but in this kind of For cases that didn’t happen in one’s own place of residence, what was really difficult to deal with was the bloodstains on the murderer’s body. How to leave the scene without bloodstains without being noticed by the witnesses—the answer is a raincoat. The murderer should have been wearing a rubber raincoat when committing the crime. After the murder, the rain will wash off the blood on the raincoat, and after the prisoner calmly leaves the scene, possible witnesses will not pay too much attention to a passerby wearing a raincoat on a heavy rainy day. I think the murderer first chose the early morning, he should think There are few witnesses in the early morning, and there is spare time to change out of the **** clothes, but in fact, it is very troublesome to change clothes, and sometimes there will be…”

“It doesn’t need to be so specific.” The system coughed and reminded.

Lin Yuetian also coughed twice: “In short, after committing the crime for the first time, he felt that this method was too troublesome and the risk was too high, so he chose to commit the crime on a rainy day to avoid the risk.”

He added: “Besides, the murder weapon used by the murderer for several crimes was different, although they were all blunt weapons… The first time was a claw hammer, the second time, a stone was found at the scene, and the third time it was used permanently. Mason’s hammer. That means he’s looking for the perfect weapon.”

Chen Chen nodded and continued to ask, “Yes, that’s right, but what’s the point of this? If you feel that the weapon is not going well, you will naturally choose to replace it.”

“Yes,” Lin Yuetian said, “The first is, this shows that the murderer is constantly improving his actions in the crimes, perhaps this is his first murder.”

“Isn’t this contradicting what you just said about having a criminal record?” Another person asked suspiciously.

“It’s not contradictory,” Lin Yuetian paused, “I mean… the first victim, Zhao Fanyun, is he really the first victim in the murderer’s series of crimes?”

“?”

Lin Yuetian said: “Actually, I have been thinking about why the murderer chooses blunt weapons… Of course, blunt weapons are much easier to use than sharp weapons, and they are more likely to kill. Sharp weapons are strictly controlled, not knives, knives, etc. Killing or injuring people, or at least making them lose their ability to call for help or resist, is very skillful…”

“Only an industry elite like you can do this, right?” The system guessed his words.

“You’re wise.” Lin Yuetian said in his head with relief.

Of course, he would not say this sentence, but continued to analyze: “However, it is undeniable that if my speculation is true, the murderer has no criminal record, it is very strange. Because to a person who has no criminal record Say, when you think of killing people, your first thought is a sharp weapon, right? Fruit knives, screwdrivers, etc.—why do prisoners think of using blunt weapons?”

“Why?” Chen Chen was fascinated and couldn’t help but ask.

“I make a bold guess,” said Lin Yuetian, “the first victim in this case is someone else, and it is very likely that he died of a sharp weapon injury, or even excessive blood loss after being stabbed multiple times. I guess the culprit is After using a sharp weapon once, I found that the sharp weapon was not easy, so I changed the blunt one. That’s why I said he had a criminal record.”

Lin Yuetian said: “So I think we should investigate all unsolved murder cases with sharp weapons in the city within half a year, and investigate together with this case after research.”
