Hearing Yuwen Jiahong's words, Kun Xiaotian on the side immediately pouted.

"The Higher Attack Academy, the direction of research is how to kill demons efficiently, as a professor of the Higher Attack Academy, isn't the best thing to do is assassination?"

"So how can you be sure that she is not a murderer? Because of gender? This is too arbitrary, if you want to say that it is impossible to kill, it must be Instructor Li of the Berserker Academy, he is a battle maniac, to kill these three people, one punch is enough, and there is no need for a knife at all!"

Yuwen Jiahong, who heard this, immediately mocked,

"Cut, if he breaks these three people with one punch, anyone can guess that he did it, in order to avoid suspicion, of course use a knife!"

Iwayama frowned when he heard this.

"It's just nonsense, Sima Yuanyao has been practicing swordsmanship, but he can't kill these three people with one sword, let Instructor Li, who is good at boxing, use a knife to kill these three people in seconds, it's just a joke, are you a demon like the captain when he is also the captain?"

When Sima Yuanyao heard this, he said unhappily.

"We're not him, who knows if he'll practice swordsmanship in private, maybe he's a hidden master, maybe he's a master!"

Hearing this, Yuwen Jiahong said.

"You can't conclude that Professor Liu is a murderer just because he is a professor at the Higher School of Assault, it's ridiculous, it's the funniest joke I've ever heard. “

Chen Yongsheng, who heard the four people arguing, sighed helplessly.

In fact

If it's on Earth, it's not too simple for this kind of case.

Not to mention professional criminal investigators, even ordinary people who have only watched a few criminal investigation dramas can say it immediately.

To judge who is likely to do the case, it is enough to investigate whether they have the time and motive to commit the crime.

As long as it is at the time of the crime, have an alibi.

can rule out suspicion.

But now it's clear.

These four people are completely relying on their own preferences to make decisions, which is simply nonsense.

But just when Chen Yongsheng wanted to make a clear analysis and tell them about the process.

A prompt pops up.

Systems: Please don't spread the science of systems that don't belong to this world, so as not to cause unnecessary chain reactions, what the host needs to do is to become strong enough for everyone to look up to, and be curious about the host's abilities, so as to develop their own disciplines that are more suitable for them, and in the process, realize the importance of maintaining biological diversity, rather than host cramming.

Chen Yongsheng, who saw this prompt, frowned.

"Don't talk about the system, just talk about some simple analysis processes and ideas, isn't it okay?"

System: A simple analytical process that does not belong to systematic science communication.

Seeing this news, Chen Yongsheng sighed helplessly.

Then he interrupted.

"Don't argue about these things, people can lie, and everyone has a light and a dark side in their hearts, so to judge whether a person has done this or not, we need to argue not about his daily performance. “

"Rather, we must first investigate whether they had the time to commit the crime, whether they were present at the scene of the murder during that time period, and whether he had a motive for killing these three people. “

Hearing this, Yuwen Jiahong, who was sexy, immediately picked up the phone and said,

"I have Professor Liu's phone number, I'll call her!"

Chen Yongsheng, who saw this scene, really had a headache,

"Don't fight, investigate the side first. “

Everyone who heard this was stunned.

"Side-by-side, do you mean to ask her student, or to ask his partner?"

This made Chen Yousheng's brain hurt, and he didn't know how to explain it to them at all, so he said immediately.

"Well, you don't have to do anything now, just follow my command. “

Hearing this, the four of them looked at each other, and then fell silent

At the same time, Chen Yongsheng turned around and said.

"Side investigation, refers not only to ask her students and partners, but to avoid the front, through other means, to make some judgments, since you don't understand at all, don't be busy moving first, follow me, let's go to the scene of the crime, do some investigation. “

"If it goes well, the information from the scene will tell us who is more likely to be the murderer. “

The other four were a little confused.

While following behind Chen Yongsheng, he asked curiously.

"There is no trace left at the scene, what are we going to do?"

"That's right, the information of the Martial Arts Association has been given to us, there is no trace of the scene, and it has rained, we won't have any harvest if we go, why go there?"

"This is an obvious waste of time, it's been so long since we've been to the scene, it's raining again, and so many people have checked it, but they haven't found any useful clues, what's the use of us going?"

Chen Yongsheng, who heard their words, sighed helplessly, and after thinking about it, he couldn't help but say,

"According to the Lokadian principle of material exchange, when a criminal commits a crime at the scene of a crime, he must act directly or indirectly on the scene. “

"Consciously or unconsciously, it leaves traces of its activity. “

"According to the different forms of traces, the traces of crime at the scene can be divided into material traces and psychological traces. “

"When investigators investigate crime scenes, they usually pay more attention to traditional material traces such as hand prints and footprints, but often ignore psychological traces."

The four people who heard this were all stunned and didn't understand at all, what was Chen Yongsheng talking about?

Although my eyes were full of curiosity, I didn't dare to ask because I didn't understand.

So I had to follow behind Chen Yongsheng and went straight to the alley where the murder occurred.

By this time, it had rained and the sky was clear.

In the alley, apart from the outline of the three people who were killed and fell to the ground, there was basically nothing left in the alley.

As for the traces, there was nothing but the traces that appeared after the stagnant water in the alley had flowed.

At this time, Chen Yongsheng stood at the place where the three people were killed, in front.

After looking at it, I drew a circle on the ground.

Then he stepped aside.

"Now that I think about it, the assailant killed three people with a single knife and then left, without touching the finances of the three people, and without mending the knife, why? Why did he do this?"

Sima Yuanyao, who heard this, had bright eyes,

"The strong self-confidence of the Spirit Emperor-level martial artist, he can kill three people in seconds with one sword, and he doesn't need to make up the knife at all, so he naturally doesn't need to turn back, and the perpetrator is not short of money. “

"I'm talking about motives, why did the assailant kill these three people?" Chen Yongsheng raised his eyebrows and looked at the other three.

The three of them looked at each other,

Kun Xiaotian was anxious.

"Boss, what are you thinking? A Spirit Emperor-level powerhouse wants to kill three people who are not highly cultivated, and he still needs a reason?

Chen Yousheng smiled angrily when he heard this.

"Do you all think so? Are you kidding? The psychological traces here are already obvious, if it is purely for revenge and venting anger, for a strong warrior, a knife cutting the throat is far less pleasant than a knife decapitation, after all, the different parts of the body look more impactful, more hearty.
