After simulating crimes 100,000 times, I became an ace detective

This seems like a playful suicide note.

Or rather...

It shouldn't be called a suicide note, because there is no regret or unwillingness written in it.

He didn't explain his funeral like others did.

But when Su Ming held it in his hand, he felt unspeakably heavy and sad.

because.

Although there is no fear in this letter, regret and misery are written in every word.

Especially that sentence.

Never come again in the next life...

...

Silence for a few seconds.

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

Although simulated crime a hundred thousand times.

He also became a brutal murderer countless times.

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

While closing your eyes.

Su Ming kept asking himself questions in his mind, trying to sort out his thoughts and find the correct answer.

Did the deceased commit suicide?

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

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

Why was the dust on the stairs on the sixth floor swept away in order to hide the footprints, but the garbage on the rooftop was not disposed of, leaving traces of my own DNA?

Is it possible that the items on the rooftop were deliberately placed by the murderer in order to make it look like the deceased committed suicide, creating a perfect crime?

The deceased said that he was redundant. Have his parents divorced and started their own families? What does the dispensability in the letter mean? Have a bad relationship with your classmates? Or suicide due to depression caused by school violence?

...

Put away objects that may contain DNA.

Xu Changsheng stood up and asked curiously when he saw Su Ming closing his eyes slightly.

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

"Are there any key clues in this letter? Or have you inferred any useful information?"

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

"Brother Sheng, you can read this letter."

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

"Then I will summarize the only clues we have so far and summarize the general inferences we can get."

Speaking of which.

Su Ming paused for two seconds, inferred various clues and continued.

"first."

"At present, it should be confirmed that the deceased committed suicide. The posture of falling on his back is very special. I can't find any other possibility except that he jumped on his own."

"But even though he jumped on his own, we cannot rule out the possibility that the suspect used drugs or mental cues to control the deceased in extreme circumstances."

"Because it's in the previous case files."

"There have also been special cases where the victim was controlled by drugs or mentally suggestive, leading to the final suicide."

"As for."

"I have three guesses about why the deceased's left wrist artery was cut..."

"First, before the deceased fell, she asked her companions who came to the rooftop together to give her a chance to die peacefully if they found her alive after going downstairs."

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

"Third, the whole thing may have been influenced by other people. Under this person's instruction or request, the companion must ensure that the deceased died."

"No matter which of these three conjectures, I believe that the person who cut the radial artery of the deceased was the companion who was chatting and eating snacks with the deceased!"

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

"It is necessary to determine the specific identity of the companion, or tentatively called the suspect, as soon as possible."

“Because in my opinion, this person has too many doubts!!!”

"If the two were friends, why did they not show any signs of trying to dissuade the deceased from committing suicide, and finally caused secondary harm to the deceased."

"Secondly."

"The dust on the sixth floor has been swept away. I don't want to leave any footprints, but I don't care if the DNA traces left on the rooftop can explain one thing..."

"Footprints are easier to find her than DNA?"

"as well as."

"You think our police will definitely be able to find her in the end, so you don't process your DNA and just hide the footprints in the hope that she won't be found too early?"

"And the most important thing."

"By being able to drink AD calcium milk, eat spicy potato chips, and sit and chat with the deceased, we can basically infer that this person is most likely to be the same age as the deceased."

"How come you have such a strong psychological quality when you are so young?"

"It is really strange to see that the deceased who fell from the building did not have any fear at all, and could even step forward and cut the radial artery with a sharp knife."

"It makes me extremely suspicious..."

"It is very likely that not only two middle school students were involved in this case, but there may also be people behind the scenes, but the situation cannot be determined based on inference alone."

"at last."

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

"On the one hand, we need to understand the family situation and interpersonal relationships of the deceased, find the real reason for his suicide, and find out whether the deceased has been in this state for a long time, or whether there are factors that were deliberately guided by others."

"On the other hand, we need to search for the suspect who witnessed this case. According to the clues we have obtained so far, we can infer..."

"The suspect should be between 14 and 17 years old, female, and should have a good relationship with the deceased, or one of the deceased's only friends."

"Based on the suspect's practice of wiping off footprints but leaving DNA, I think the suspect is likely to have a defect in his legs."

"He is also a type of person who is excluded and ignored in school. Since the two have similar experiences, they can become pretty good friends."

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

"That is..."

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

"Why are you not afraid of being found, but worried about being found too early?"

"If you think about it in an extreme way, it is very likely that the suspect is also going to..."

"Commit suicide!!!"

At this moment.

When Su Ming finished his inference.

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

But he...

He didn't have time to say anything, and immediately returned to the stairs, turned on the flashlight and looked for something in the dusty stairs on the fifth floor.

Half a minute later.

Among a pile of faint footprints.

Xu Changsheng found a footprint against the wall, with the front sole of the foot touching the ground and the back sole floating!!!

Moreover.

It was not just a coincidence.

Looking carefully.

You can clearly see that there are such footprints on every step.

Xu Changsheng's eyes condensed slightly. He didn't expect that the suspect had a more obvious disease in his legs, just as Su Ming had just deduced.

But the most important thing is...

According to Su Ming, this suspect is also going to commit suicide? ! !
