"Seeing that your question is so detailed, do you think the delivery man is also suspicious?" Zhang Yichi asked.

Team Yi was old and a little tired in the middle of the night, so he rubbed the bridge of his nose: "My intuition tells me that the murderer this time is very tricky, so I don't want to miss any possibilities." ”

Zhang Yichi thought so: "Indeed, we can't let go of any possibility. However, if it is a delivery man, then we have to figure out how he managed to make Meng Xiaoyang eat takeaway and then be killed in dozens of seconds, and then write blood on the wall of the living room, and clean up his traces, not even fingerprints and footprints. ”

"It's really impossible, so he's not the focus of our suspicions. If Xiao Mo checks and determines that the family situation he described is true and has no connection with the deceased, then the suspicion can be completely ruled out. The Iraqi team strode towards the residential building.

Zhang Yichi slowed down slightly, looked at the tired but still energetic back of the Iraqi team, and recalled Li Xiangnian for a while.

It's the same experienced old cop.

Will this reincarnation world really give them a huge boost for no reason?

The murderer left the words 'perfect crime' on the wall, what kind of crime can be called a perfect crime?

He entered the building with the Iraqi team, and the police force assigned to him is currently conducting investigations in various households.

Such a vicious and appalling case has not happened for decades in this small city that is about to flourish, and now everyone is in a 200 percent spirit, and we want to arrest as soon as possible this murderer who provokes the police, who may have committed many cases and is very likely to continue to commit crimes in the future.

Progress was rapid, and preliminary findings came out in the early hours of the morning. And because it was too late, disturbing the residents and the police was also very tired, so the rest had to wait until the morning to continue.

On the way back to the bureau, Team Yi and Zhang Yichi flipped through the preliminary investigation results.

Two of these people got noticed.

One is a boy who is still in his third year of high school, because of the pressure of studying, the pressure of his parents, many quarrels broke out in the family, and the child has also had several suicidal tendencies. According to parents, children's usual hobbies are only watching movies, among which mystery and crime movies are the majority.

One is a disabled person who lives alone downstairs of the deceased, has an arm amputated due to a car accident, and usually goes to a relative's shop to help earn money to live. According to the residents next door, the middle-aged disabled man has a bad temper, often drinks heavily, plays adult movies loudly at home in the middle of the night, and there have been conflicts between the two sides.

These two, one is world-weary and stressful and likes crime films, and the other is not psychologically normal and short-tempered.

Compared to the rest of the 61 households, both were relatively motivated and capable of committing crimes.

And the day of the crime was Saturday, and neither of them went out during the time when the deceased died. The boy who was still in his third year of high school, his parents were working overtime that day, only urging the child to study hard at home.

That is, both of them are at home alone, and there are certain conditions to commit crimes.

"Tomorrow we will focus on investigating these two people, but the others can't let up." After returning to the bureau, the Iraqi team held a meeting with the rest of the task force set up overnight, "The murderer wants to commit a perfect crime, and we must try to follow his train of thought." How can we not be doubted, or how can we lower our suspicion of Him. If you have any thoughts, you can tell me. ”

"I don't think the murderers will be them, their conditions are too eye-catching, too easy for us to notice. The murderer wants to commit a perfect crime, he must be a far-sighted person, how could he put himself at a disadvantage in the first place? "Someone has an opinion.

"A perfect crime does not depend on whether or not you will be suspected, but even if you are suspected, even if you know that you are the murderer, there is no evidence to prove it. So I think these two people are very suspicious, and being suspected is not considered a disadvantage, and even the most dangerous identity is the safest identity, and the murderer will feel that this can reduce the suspicion. "There are those who have the opposite opinion.

"It is not excluded that the murderer is actually not as complicated as we think, and the so-called perfect crime is a trick that makes us think about things complicated and ignore those simple things."

"I think judging from the current performance, the murderer is indeed not simple......"

Everyone has their opinions.

The Iraqi team did not respond to the opinions of several people, but listened silently and arranged to sort out the information currently in their possession: "Let's take a look at the information we currently have, only this information can prove your speculation, and can restore what happened and what the truth is." ”

At present, it is known that the deceased Meng Xiaoyang lived alone and basically did not go out, so he had almost no contact with his neighbors, let alone whether there would be any conflicts.

He is a mystery writer who usually supports himself through manuscript fees.

According to what the delivery man said, at least at 7:15, Meng Xiaoyang was not unusual. So everything happened in the five minutes between 7:15 and 7:20 a.m., when the murderer reported the crime.

In these five minutes, Meng Xiaoyang ate a curry chazuke delivered by the delivery man, and then was stabbed seven times. The murderer used Meng Xiaoyang's blood to write on the wall of the living room, 'Please come and test whether this is a perfect crime'. Then he cleaned up all traces of himself, footprints, fingerprints, so that no clues about the murderer were left.

Counting the delivery people, there are 62 people who have been in and out of residential buildings and live here.

At present, a high school student and a middle-aged person with a broken arm are the key suspects.

At the scene of the crime, there was nothing unusual except for the living room, and the murderer should have only entered the living room.

"There's something weird." Zhang Yichi asked a question that had been speculated before, "Meng Xiaoyang ate the takeaway, but we didn't see a takeaway box, could it be that he was really taken away by the murderer?" ”

"The answer is yes." "And the murderer took away the takeaway box, not because he had any peculiar fetishes. In my opinion, it should be some important information on the take-out box, so the murderer must take it away. ”

Someone realized something: "Then we can check the monitoring, after that time period, someone came out to take out the garbage." The take-out box must be thrown away, if no one takes out the garbage, it means that the take-out box is still somewhere in the building, as long as the take-out box is found, the murderer should be found. ”

Team Yi nodded slightly, thinking in his heart what information could be generated on the takeaway box, which was worth the murderer's risk of taking it away.

At this time, a technician came over and reported the situation.

"The fingerprints on the key inserted in the door of the deceased were found to match the fingerprints of the delivery person."
