The first deceased died five days ago, the crime occurred near Jiaxin Garden, Jiaxin Garden is a high-end residential area, belongs to the development of real estate in Longjiang City, the surrounding area has not been fully developed for the time being, some places are still short old-fashioned residential buildings, some places are even very desolate, but in recent years, Longjiang City has continued to develop, Jiaxin Garden near the real estate potential is very large, the price has reached more than 25,000.

Liu Xuebin took Jiang Yu to an alley near Jiaxin Garden, where there was also a white line painting, which was the scene of the crime.

Jiang Yu stepped forward, squatted on the ground and looked carefully, sniffing the smell lightly while watching. The first homicide was similar to the third, and the deceased did not struggle too much, so there were no visible traces.

"Basically, it can be determined that the deceased and the murderer knew each other, and the deceased died very suddenly, and there are basically no obvious traces around." Jiang Yu stood up and asked Liu Xuebin, "The deceased lives here?" ”

"Yes, the deceased lived in Jiaxin Garden, and it was only three months since he moved in."

"What about the families of the deceased?"

"The deceased had been divorced for many years and had a daughter studying abroad."

"That means the deceased was alone, and there's no way to prove how the deceased got here?" Jiang Yu frowned.

"Yes, we can't find any eyewitnesses, the last person the deceased saw before his death was a nurse at the hospital, and more than ten hours had passed since the deceased left the hospital, and the deceased was on vacation that day." Liu Xuebin said.

"Interesting." Jiang Yu squinted his eyes, it seems that the murderer is a master, I now have some suspicions that the murderer has an unknown purpose, and I don't know if he will commit crimes in the future.

"How?" Liu Xuebin looked at Jiang Yu: "You mean that the three cases were actually committed by the same person?" ”

"Although I don't have direct evidence, it's almost certain that this is a serial murder case." Jiang Yu stood up: "Let's go to the next place, the next place where the deceased has struggled, there should be more obvious traces, right?" ”

Liu Xuebin shook his head while opening the car door: "There are no clues, there is no difference between the crime scene and this place and the one last night, the only difference." ”

"How so?" Jiang Yu looked at Liu Xuebin: "The deceased was obviously killed by a blunt object, judging from the situation of the deceased, there are traces of a fight, how can there be no traces?" ”

"Basically, it can be determined that the place where the deceased was found was the scene of the first crime, and the reason why no clues were found can only show that the murderer had enough time to deal with the scene." Liu Xuebin said.

"It seems that this is the only explanation." Jiang Yu nodded: "Let's go, let's take a look." ”

The second crime scene is also in a relatively secluded alley, and it is worth mentioning that it is also near the deceased's residence, combined with Wu Liang's death next to the hospital, so the three cases already have another similarity, all near the deceased's work or residence.

"It seems that the dead and the murderer also know each other, otherwise why would the dead come to this place at night?" Jiang Yu looked at the scene of the crime and said: "There is no need for the deceased to go through here whether he is going home or going out, the only explanation is that he was called out, and being able to call the deceased out at least means that he is an acquaintance." ”

Liu Xuebin nodded: "I have thought of this after you left last night, and I called up all the surveillance near the three crime scenes, but no suspect was found." ”

Jiang Yu waved his hand: "The surveillance video basically can't capture the murderer's appearance, if he is a master, he can completely avoid it, and if the murderer is a public size, it will be even more troublesome to investigate." ”

While speaking, Jiang Yu stepped out of the car, the blood stains on the ground had not been treated, and the scene could be seen.

Jiang Yu bent down and asked while looking, "There is no blood stain of the murderer at the scene?" ”

"No, nothing suspicious was found except for the deceased." Liu Xuebin shook his head.

Jiang Yu didn't speak, squatted down and looked carefully, and suddenly stretched out his hand and pointed: "Director Liu, look here." ”

Liu Xuebin stepped forward: "This is ...... Left behind when the murderer and the deceased fought? ”

Jiang Yu refers to an inconspicuous trace on the side wall, the wall on the side is an old-fashioned brick wall of some ages, there are many traces, and you can't find this trace if you don't look carefully.

"Judging from this trace, it should have been inadvertently encountered by the murder weapon that was fought at that time, and it is relatively new."

"I'm going to call someone to get it identified." Liu Xuebin took out his mobile phone, and after a while, someone from the police station began to test with professional instruments.

"It's a new trace, indeed." Liu Xuebin looked at Jiang Yu.

"In this case, the murderer should have carried a murder weapon." Jiang Yu looked around: "The blunt weapon is not easy to deal with, could it be that the murderer will directly take the murder weapon away from the scene of the crime?" ”

"Generally speaking, it's not likely." Liu Xuebin shook his head: "If it is a blunt object, it is often more conspicuous, so it is easy to be exposed." ”

"Then look around, maybe you'll find something." As he spoke, Jiang Yu was looking around, and when he was almost at the end of the alley, Jiang Yu suddenly walked to the wall and pulled out a brick that had moved and fallen off from it.

Liu Xuebin hurriedly stepped forward and looked at the brick in Jiang Yu's hand: "Do you suspect that this is the murder weapon?" ”

"Get someone to check it out first." Jiang Yu gently handed the brick to the policeman who stepped forward on the side, and said with a smile: "I considered it from the assumption that the three cases were committed by one person. ”

Liu Xuebin is not stupid, on the contrary, he is very smart, and his eyes lit up when he heard this: "You mean that the murder weapon of the murderer in the other two cases is just a dagger, and if this case is committed by the same person, the murder weapon should also be a dagger?" ”

"Yes." Jiang Yu nodded: "But the murder weapon in this case is a blunt weapon, so there is only one explanation, the murderer in this case is taken from the scene." ”

The results of the comparison on the other side came out quickly: "Liu Ju, according to our analysis of the comparison results, the residual fragments of the skin on the back of the deceased's head are basically similar to the fragments on this. ”

"Looks like this is the murder weapon." Liu Xuebin frowned, but why didn't the murderer use a dagger?

Jiang Yu clapped his hands: "Do you remember what I said before, the murderer is not tall, his right arm is very powerful, but he is not necessarily burly, the deceased is a man, tall and tall, if the other party is wary, the deceased may not be able to succeed, so I guess that the deceased attacked with a brick in the back, it is obvious that the murderer knows the human body very well, although the blow in the back of the head was not fatal, but almost made the deceased lose most of his mobility......

I have to say that Jiang Yu's explanation is very reasonable, as if he saw it with his own eyes.

Liu Xuebin looked at Jiang Yu with a smile: "Director Jiang is worthy of Director Jiang, so can you guess the murderer's motive for committing the crime?" ”

Jiang Yu looked at Liu Xuebin directly: "Is there any benefit, you won't let me contribute to this case alone, right?" ”

Liu Xuebin was originally just joking, but when he heard Jiang Yu say this, he was subconsciously stunned: "You really guessed?" ”

"Huh."

"What do you mean?" Liu Xuebin was anxious: "If you guess correctly, I promise you a request, no matter what the request?" ”

"That's what you said?" Jiang Yu looked at Liu Xuebin with a smile.

"You talk about it first, if I say it, I definitely say that it counts, and I still don't believe it, are you really so godly?" Liu Xuebin pursed his lips.

"You don't have to give me the agitation method."

Jiang Yu said as he walked to the car: "It's not early, invite me to lunch first, if I am satisfied, I might as well tell you." ”

"This guy." Liu Xuebin smiled bitterly and shook his head, he was eaten to death by Jiang Yu, this guy's reasoning ability is really speechless, and he is really condescending to not be a policeman.

After getting into the car, Liu Xuebin diligently handed Jiang Yu a bottle of drink: "Director Jiang, it's no problem to eat, you can eat anything, you say it first, it's important to solve the case, if it's really a serial case, we may cause someone to be killed again if we delay it so much." ”

Jiang Yu unscrewed the cap of the bottle and took a big sip before asking: "What are the motives for serial homicides?" ”

Liu Xuebin was stunned for a moment, thoughtful: "Most of them are vendettas, and at the same time, it does not rule out any other purposes, such as perverted murderers." ”

The perverted murderers in Liu Xuebin's mouth are often divided into many kinds, some have special hobbies, and some just like to enjoy the process of committing crimes, which cannot be generalized.

Jiang Yu nodded: "In this way, let's analyze, the deceased are all doctors, and they know the murderer, the murderer's modus operandi is very sophisticated, and it is obvious that it has been carefully planned, so it may be the best explanation." ”

Liu Xuebin was taken aback: "The murderer hates the doctors, or does the murderer have relatives who have been misdiagnosed and mistreated by these doctors......?" ”

"It doesn't have to be a misdiagnosis or a mistreatment, right?" Jiang Yu didn't like to hear this: "Judging from the identity of the deceased, they are all surgeons, and it is obvious that the murderer is targeted, so the biggest possibility is that the murderer has relatives who have serious external injuries, but they have not been rescued, which makes the deceased have a hatred of doctors, and then retaliate." ”

Liu Xuebin slapped his thigh: "This possibility is very high, if Director Jiang is guessed by you, you will have made a great contribution." ”

Liu Xuebin is really excited, although everything is speculation now, and there is no evidence, but the police solved the case at the beginning to determine the most likely idea to investigate and find evidence, and then eliminate it.

Jiang Yu's guess is equivalent to giving the police an idea, Liu Xuebin can first start an investigation from this idea, targeted investigation, if there is no gain, it is natural to guess wrong, if there is a harvest, then it proves that Jiang Yu guessed correctly.

Although Liu Xuebin is still not sure whether Jiang Yu guessed correctly, this idea undoubtedly gave Liu Xuebin a direction, which is much stronger than him looking for a needle in a haystack.

"Merit?" Jiang Yu pouted: "Who is rare." ”

"Enlightenment, Doctor Jiang, you are also helping the people's police and the people." Liu Xuebin couldn't cry or laugh, this Director Jiang may have the ability, but he is too aimed at him.
