After 100,000 simulated crimes, I became an ace detective

This seems like a playful suicide note.

Or rather....

It should not be said to be a suicide note, because it does not write about his regrets and unwillingness at all.

He didn't explain the aftermath like others.

But Su Ming held it in his hand, and it was a little indescribably heavy and sad.

Because.

Although this letter does not write fear, it is written with regret and sorrow.

Especially that sentence.

Never come again in the next life....

......

Silence for seconds.

Su Ming closed his eyes slightly and slowly suppressed some complicated emotions.

Although mock crimes a hundred thousand times.

He has been a brutal murderer for an unknown number of times.

The heart should be as cold as ice, but this is not a simulation, it is a real reality of flesh and blood, and people are often emotional.

While closing your eyes.

Su Ming kept asking himself in his heart, trying to clear his thoughts and find the right answer.

Did the deceased commit suicide?

If it was suicide, why was the radial artery in the left wrist still cut?

Why didn't the girl who spent the last period of time here with the deceased choose to discourage? On the contrary, it seems to be very cooperative?

Why was the dust on the stairs on the sixth floor swept away, intending to hide the footprints, but leaving their own DNA traces without disposing of the garbage on the roof?

Is it possible that these items on the rooftop were deliberately laid out by the murderer in order to shape the appearance of the deceased's suicide and form a perfect crime?

The deceased said that he was redundant, and did his parents divorce and start their own families? What does the dispensability in the letter mean? Bad relationship with classmates? Or depressive suicide due to school violence?

......

Put away objects that may have DNA.

Xu Changsheng stood up and saw Su Ming with slightly closed eyes, and asked with some curiosity.

"Xiao Ming, why are you closing your eyes?"

"What are the key clues in this letter?" Or did you deduce any useful information?

Su Ming, who had almost sorted out his thoughts, opened his eyes at the right time and handed the envelope to Xu Changsheng and replied.

"Brother Sheng, you can read this letter."

"These are not last words, but the words left to us by the deceased."

"Then I will say that I will take the only clues so far and integrate and sort out the rough inferences that can be obtained."

Speaking of which.

Su Ming paused slightly for two seconds, sorted out the various clues and continued.

"First of all."

"At present, it should be possible to determine that the deceased committed suicide, and the posture of falling on his back is very special, and I can't find any other possibility except jumping on his own."

"But even if it jumps on its own, it cannot be ruled out whether there are extreme situations in which the suspect used drugs or mental cues to control the deceased."

"Because in the case file in the past."

"There have also been special cases of victims being controlled by drugs, or mental suggestion, leading to final suicide."

"As for."

"Why the left wrist artery of the deceased was cut, I have roughly three conjectures now..."

"First, before the deceased fell from the building, he asked his companions who came to the rooftop with him, if he went downstairs and found that she was unexpectedly not dead, he would give her a chance to die safely."

"Second, the companion saw that the deceased was not dead, and could not bear her suffering from this, so he chose to cut the radial artery of the deceased."

"Thirdly, there may be other influences in the whole thing, and at the behest or request of this person, that companion must ensure the death of the deceased."

"No matter which of these three conjectures, I think that the person who cut the radial artery of the deceased is the companion who chatted and ate snacks with the deceased!"

"So I think the key question is..."

"The specific identity of the companion, or suspect, must be determined as soon as possible."

"Because this guy seems to me ... There are really too many doubts!!

"If the two are friends, why didn't they try to dissuade the deceased from taking his own life, and finally caused secondary damage to the deceased."

"Secondly."

"The dust on the sixth floor was swept away, and I didn't want to leave footprints because of this, but I didn't care about the DNA traces left on the rooftop, can it say one thing..."

"And."

"Think we, the police, will find her in the end, so they don't process their DNA and only hide their footprints so they don't get found too early?"

"And the most important point."

"Through the characteristics of being able to drink AD calcium milk with the deceased, eat spicy potato chips, sit and chat, etc., it can basically be inferred that the person is likely to be similar to the age of the deceased."

"I am so young, why can I have such a strong psychological quality?"

"It's really strange to see that the deceased who fell from the building did not have the slightest fear, and even stepped forward and cut the radial artery with a sharp blade."

"

It is very likely that this case is not only two middle school students involved, and there may be people behind the instructions, but it is not yet possible to determine the situation by inference alone."

"Finally."

"Brother Sheng, I think we must act in two ways."

"On the one hand, it is necessary to understand the family situation and interpersonal relationships of the deceased, find out the real cause of his suicide, and dig out whether the deceased has been in this state for a long time, or whether there are factors that have been deliberately guided."

"On the other hand, it is necessary to comprehensively search for the suspect who witnessed this case, and infer it according to the clues obtained so far..."

"The suspect should also be between 14 and 17 years old, gender female, and the relationship with the deceased should not be bad, or one of the deceased's only friends."

"Judging by the suspect's practice of erasing his footprints but leaving DNA, I think the suspect is likely to have a defective leg,"

"It also belongs to the category of people who are excluded and ignored in school, and because the two have similar experiences, they can become quite good friends."

"There is also a very high probability of one thing."

"From

the suspect's current practice of covering up her whereabouts, it is likely that we are not trying to escape, but simply let us find her later."

"Then why not be afraid of being found, but worried about being found too early?"

"If you think to the extreme point, it is likely that this suspect is also going to..." "

Suicide !!"

Now.

When Su Ming finished this inference.

Xu Changsheng also finished reading the letter left by the deceased.

But he....

Without having time to say anything, he immediately returned to the position of the stairs, turned on the flashlight and looked for something in the dusty stairs on the fifth floor.

Half a minute later.

In a large pile of looming footprints.

Xu Changsheng found a footprint against the wall, and there was an obvious situation of the forefoot landing on the ground and the hind foot floating on the ground!!

And.

It wasn't just an accident.

Look closely.

You can clearly see that every step has this footprint.

Xu Changsheng's eyes froze slightly, but he didn't expect that it was the same as Su Ming had just deduced, and the suspect had a more obvious disease in his leg.

But the most important thing is....

According to Su Ming, the suspect also committed suicide?!!
