Luo Yuan slanted the corners of his mouth: "Aren't you in a hurry?" Still interested in listening to my explanation? ”

"......" Zhao Yixi was speechless for a while, turned to the other policemen and said, "Didn't you hear?" Now go and check the city's ...... immediately"

"Wait a minute!" Luo Yuan rolled his eyes and shouted.

Boy!

Check the whole city?

This can't be a week, huh?

Luo Yuan pointed to six people: "The three of you go to the three major express companies and ask for their employee lists, the other three people go to the branches of the three major food delivery apps and ask for the list of employees, and the others go to each deceased's home to find out if there are any courier orders, or food orders and the like." ”

"Yes!"

These cops also breathe a sigh of relief!

Fortunately, it is not a city-wide investigation, and in this era, there are too many otaku and otaku, so the food ordering and express delivery industry is very prosperous.

There are no less than 5,000 couriers in the city alone!

Counting the delivery people, even if the number of people is not tens of thousands, it is almost the same.

If you look for them one by one, it is estimated that you may not be able to find the suspect in two months.

Under Luo Yuan's arrangement, it became a list, and the work of finding the courier order became much simpler.

But this time, Luo Yuan was also sure that he could find the murderer.

It was one o'clock in the afternoon, and Zhao Yixi was not polite at all, and directly dispatched all the police.

For a while, in the entire office, Luo Yuan and Zhao Yixi were left.

Zhao Yixi couldn't help but ask, "Can you tell me how you deduced it?" I can't see that you're still a profiler! ”

Profiler.

That is, psychologists.

In fact, many police forces have advisers in this area.

It's just that Su Jiang's previous profiler passed away last year.

This becomes cumbersome.

The profiler is only an auxiliary role, and will only be used when encountering a major case.

Even if it is given from above, it will not work at the critical moment, and it is useless!

The director also took the former criminal police captain to several universities, trying to find some professors, or students in this area, but there were no suitable ones.

and the above application for this kind of talent, but this kind of talent is rare, even if it is specially cultivated by the police university, it depends on the talent of the student, please from other places, and this money is very batch.

So until now, the Sujiang detachment has not had a suitable profiler.

Luo Yuan said lightly: "I'm not a profiler, and I don't have such a strong knowledge of psychology, but I just understand it slightly." ”

Zhao Yixi pursed her lips.

If Luo Yuan understands a little, then she doesn't understand anything.

"It's easy to reason about what I'm talking about." Luo Yuan said lightly.

"Simple? Why didn't I feel it? The murderer didn't even leave a clue......"

Luo Yuan waved his hand and said, "There are cigarette butts, and there are so many cases!" What more clues do you want? You are just brainwashed by fingerprints and passion killing. ”

Zhao Yixi sighed.

Indeed, most of the cases handled by Zhao Yixi are murders of passion, or cases with key logic.

Like for money, for women, or on the spur of the moment.

In this kind of case, as long as forensic personnel are dispatched, many people's fingerprints can basically be extracted, and the suspect can be easily locked.

If you deal with more cases of this kind, you will develop the inertia of thinking, and you will naturally not be able to think of anything else.

Luo Yuan said: "The murderer can enter so many people's homes, which means that he must be doing door-to-door service, and I found that the lock in the deceased's house is old, so I ruled out repairing the lock, although the deceased's home has a laptop, I opened it and looked at it, and it has not been redone system." Moreover, most of the households where the murderer was killed were young women, and it can even be said that there were female deceased people in every case, what does this mean? ”

Zhao Yixi thought for a while: "It shows that the deceased has a great hatred for women." ”

"That's right! You see, you can reason too. Luo Yuan said with a smile.

Zhao Yixi glanced at Luo Yuan charmingly.

That look was very cute, which made Luo Yuan slightly stunned!

At this time, Luo Yuan realized that Zhao Yixi also had a woman's side.

Zhao Yixi also found that there was something wrong with her appearance, and hurriedly corrected her expression.

Luo Yuan slanted the corners of his mouth and continued: "And men who hate women are generally either injured by women, or they are family environment problems. ”

Family environment!

Luo Yuan also said this.

Zhao Yixi asked, "Then why not the former?" ”

"If that's the case, then the man he should have killed, or the first person to die was the murderer's girlfriend! If that's the case, wouldn't it be too stupid for you to find the murderer! ”

“……”

Zhao Yixi nodded!

The first thing they do to solve the case is to collect fingerprints, and then they investigate the interpersonal relationship of the deceased, if it is a relationship between men and women, even if the murderer wants to hide it, it will be known, but no matter which one there is, there is no such problem.

And most of the deceased's family environment is very good, looking for a courier or food delivery person as a boyfriend?

The odds are slim.

"The murderer's modus operandi is very calm, and the process is very complicated! How long do you think it takes to skin a person? ”

"For a long time!"

"That's right! If you feel uncomfortable with murder, you definitely don't have this patience, so the murderer must have psychological support to do things, so there is no problem with saying that he is a perverted murderer, and this kind of psychological support is generally caused in early childhood, which is like a chronic disease, and the virus will only break out after adulthood. And out of control. ”

Luo Yuan continued: "The murderer is meticulous in his work, and he must have made a very meticulous plan for the killing, so he can escape safely every time." The thrill he gets after a successful plan can last for a long time, and he also needs time to investigate the deceased's family situation and how he committed the crime. But ......"

Speaking of this, Luo Yuan fell into deep thought and did not say any more.

Zhao Yixi's eyes lit up: "But what?" ”

"But I guess this case should be different from the previous ones."

"Why?"

Luo Yuan pointed to the file and said: "The murderer also made a plan to kill many people at the same time before, and he did it very artistically, look at this!" ”

Zhao Yixi looked fixedly, and Luo Yuan was referring to a photo of the scene.

There were three corpses on it, one man hanged in the middle of the room, and the other two female corpses, all poisoned, kneeling on either side with a pale face.

"Look! Does the position of the two female corpses look like a confession to the hanged man in the middle? ”

Zhao Yixi nodded and said, "That's right!" I've also seen this case, one is a man's ex-girlfriend, and the reason for the breakup written on the file is that the woman cheated, and the other woman is the man's current girlfriend, but no cheating partner was found. ”

Luo Yuan shook his head and said, "You guys are really relying too much on the results of the investigation. ”
