Wu Hui finished the review. Of course, he had prepared more than one plan. In addition to killing people in the toilet, he could also kill people on the playground behind the school, in the community on weekends, in the debris pile under the dormitory building, and in the green area of the school.
He just needs to keep an eye on the target and wait for the person to enter any place alone. Of course, this is a bit of a hit and miss, and it won't matter if none of the targets go.
Of course, Wu Hui decided to use this plan only after observing the target's movement pattern in advance.
The key to the whole process is not to do unnecessary things and to use as few steps as possible to complete a simple murder case. If we say that other people's various exquisite layouts and techniques are giving people advanced math questions such as calculus and definite integrals. Then Wu Hui gave him a multiplication problem of twenty-digit numbers. .five
Advanced math can be solved by finding the right method. Of course, it requires a very high level of skill. This kind of multiplication will take half a day even if someone is quick in mental arithmetic.
Use a detailed and thorough layout to execute a plan with the shortest and simplest process.
This is Wu Hui’s rule of victory.
Don't think about that for now, let's prepare to solve the case first.
He drew a serial murder case on the spot, which was very difficult at first glance. He is a ruthless person who can come up with serial murders in five days.
There were three victims in total, all of whom were school bullies like the previous case Wu Hui drew.
One died in his own community, passing by a gap in the handrail while going for a walk at night. He was attacked from behind by a murderer wearing a raincoat and pushed down.
Wu Hui estimated that the raincoat’s height, shoe size, and other items were all fake.
One died in the school's sports warehouse. He was missing for two days before being discovered in a pile of scrapped equipment by a teacher who smelled the stench. It seemed that he was pinned down by a fallen shelf, and then a steel bar penetrated his chest. The perpetrator was clearly prepared and left no fingerprints or footprints.
In fact, although the two cases occurred only one day apart, their locations were relatively close. But there is no evidence that it was done by the same person.
But as soon as the third case came out, it was quickly merged and handled. The morning after a school power outage, a third body was discovered in a toilet.
The three cases occurred within three days of each other. Although the first case was discovered first, it was the last to be carried out. The other two bodies were discovered later.
"Hiding trees in the forest?" Wu Hui frowned slightly: "It could also be a real serial murderer."
Now, the total number of three school bullies who have the motive to kill in their interpersonal relationships may be dozens. It is simply impossible to conduct inspections one by one for five days.
If it is a serial murder, these school bullies may not know the murderer at all. Then there is no way to check.
Hiding trees in the forest is also a common technique in reasoning. The theory is feasible, making it more difficult for the police to investigate from interpersonal relationships, but in practice it is very difficult. After all, it is easy to leave clues by killing someone, let alone killing three in a row.
The probability of leaving traces has tripled.
This murderer may be considered a brave person with a high skill level. Such a radical and ruthless style reminded Wu Hui of someone he knew.
Let’s start with three sites to investigate and collect clues.
There are five days to solve the case, and the time is tight and the task is heavy. Must be faster. Every case solved here reduces future competitors.
The more difficult the case is to solve, the more trouble the opponent proves to be. Then you have to work harder to break it. The first thing Wu Hui went to see was the deceased in the toilet. Well, seeing this place, he could not help but think of his previous actions in the criminal stage. In a sense, everyone's ideas are quite similar.
…
…
The toilet is a good place, it smells great and there are many people coming and going. Not easy to leave traces. In other words, even if traces are left, there is no way to trace them.
Xiao Ming still remembers how he was bullied by Duan Ba in the toilet. Whenever he doubted the risk, he recalled that day and his anger reignited. Then it becomes impossible to give up.
He planned to kill the target right in the toilet. And already prepared.
The first is the selection of the murder weapon.
want
It is a murder weapon that is easy to obtain and cannot be found through channels. In this way, even if the weapon is left directly at the scene, it will be fine.
Of course, you must wear gloves, do not leave fingerprints, and hide the murder weapon in the toilet in advance. And you have to wait for an opportunity when the toilet is empty. By the time they discovered the body, it was already too late. Hmm... Waiting seems a bit too passive.
Perhaps some other measures need to be taken.
…
…
Wu Hui's association only lasted a moment, and then he began to observe the traces of the corpse.
In terms of settings, the police will help Wu Hui complete laboratory tests, investigation and surveillance, etc., but it will take time. He needs to find the specific investigation ideas himself.
The reason why he started investigating this case was because this case caused the most noise, and it was impossible for a power outage to leave no traces.
Unless the power outage is really due to luck and the late self-study time happens, the probability is very low.
Sure enough, the police soon found signs that the circuit had been vandalized. But the key line was suddenly cut off by a shovel, and the surveillance camera only captured the person's back. Wearing a hood and school uniform, his back is to the surveillance camera.
This shovel is quite deadly. However, you can check where the shovel came from.
Soon the origin of the shovel was discovered. It was lost at the construction site next to the school. It should have been thrown in from the school fence, and then found after entering the school.
"The shoes are taller, and clothes are added under the school uniform, so you can't tell your specific body shape. Damn the school that still lets people wear long-sleeved jackets in June." Wu Hui frowned crazily at the surveillance camera: "So the body shape and height are all different. It can’t be done accurately.”
High IQ crimes are rare. Most crimes in life are not even premeditated. It's all impulse, just do it when you see it.
If it's a petty theft, people won't have time to look for you carefully, but if you commit a murder... you can be traced out easily. However, many methods of confirming appearance characteristics are difficult to use if specially disguised.
The three cases seem to have greatly increased the probability of being found, but each case is very simple and simple when viewed individually, and there is not much to investigate.
However, Wu Hui grasped the key points keenly.
How can the murderer be sure that the victim will go to the toilet before and after the power outage?
Although Wu Hui also chose to act in the toilet, he had many backup plans at that time. Even if the target did not go to the toilet, he would die elsewhere.
If the murderer determined that the target was going to the toilet in the dark, this was obviously unlikely, so he must have known in advance that the target would go to the toilet. At least there is a high probability that he will go to the toilet.
Then, this person is likely to know the victim, so he can take relevant actions. This victim is the murderer's real crime target.
He pushed up his glasses and determined the next direction of investigation.
