Zhao Lin frowned, the murderer committed crimes in the same area five times, is he confident or crazy?

"Is there anything different from before?"

He shook his head and said, "I can't see it now, I have to move the body back and examine it carefully." ”

But then he added: "If I have to say that it is different from the previous times, it is that there are more injuries on the corpse." ”

"Look...... The killer broke the blade of her left shoulder and broke three ribs, among other wounds, before killing the deceased. ”

What a pervert...... Zhao Lin gasped and glanced up at the crowd present.

It is said that the murderer likes to return to the scene of the crime, will he be in the crowd?

Zhao Lin lowered his eyes, let go of all his hearing, and carefully screened the sound of breathing, talking and walking of everyone at the scene.

After a long time, he shook his head slightly.

If he had the same sense of smell as a mink, he might be able to track the killer based on the smell he left on the deceased.

It's a pity that it's too late to absorb the spirit now.

Besides, the cost of doing so is too great, and in order to handle a case, it is really worth the loss to consume a valuable grid of spirit beast diagrams.

After inspecting the scene, Zhao Lin asked Liang Song and He Qingquan: "What do you think should be done next?" ”

Both shook their heads.

He Qingquan said: "The murderer is a martial artist, his mental ability is far stronger than that of ordinary people, and he is a habitual offender......"

He sighed as he spoke, and he didn't have any ideas.

Zhao Lin thought about it, so he asked the three of them to ask the nearby residents for news, to see if they could find clues, and go back to the yamen with him.

"Zhao Zhutou, the county is invited."

Zhao Lin went to the torture room to ask for the file, and was going to check it carefully, and as soon as he returned to the fast room, there was an errand waiting there to say.

He had no choice but to put away the file and go with the people to the government office to meet Liu County's order.

"Zhao Zhutou, I heard about this morning's case, this case is very important, please be sure to find out the real murderer immediately."

Liu County Ling didn't beat around the bush and said straight to the point.

Zhao Lin hurriedly responded: "My subordinates understand that they must go all out, but it's just ......"

Liu Xianling raised his eyebrows, "Just what?" ”

Zhao Lin said in a deep voice: "The murderer is arrogant, and he treats the garrison of our county as nothing, and his subordinates are worried that the murderer will endure for three months and be out of control. ”

"You're worried that he'll continue to fight against the wind?"

"Exactly."

Liu Xianling groaned for a while and said, "I really have to guard against it." But don't worry, I've already greeted the garrison and asked him to double the manpower to patrol the night, so as not to give the murderers a chance. ”

The county is thoughtful and thoughtful, and his subordinates admire. However, judging from the injuries of the deceased, the murderer's cultivation was at least in the bone training period, maybe he was a master of the qi realm, and he was not an opponent when he met an ordinary patrol. ”

Speaking of this, Zhao Lin paused for a moment before saying, "My subordinates suggested sending a Qi Realm master to take charge. ”

Liu Xianling glanced up at him, "Who do you think is appropriate?" ”

"Sun Zhuchang is a master of the qi realm, witty and resolute, brave and brave, and can be the best candidate."

Zhao Lin's face did not change his color.

This matter can't be borne by yourself alone, you have to pull Sun Zhang in and stay up for a few days and nights first.

Liu Xianling agreed without thinking about it: "Okay, I promise you." Sun Zhang patrols the night at night, and the position of the chief of the Dongcheng is taken by Ling during the day, and I will tell you about this later, what are the difficulties? ”

"Not for the time being, my subordinates will go to investigate the case."

Zhao Lin left the government office and went back to continue reading the file.

At noon, he came to the fast room, "Zhao Zhutou, I found this on the deceased's clothes." ”

Zhao Lin looked at it and saw that he was holding three inches of hair in his hand.

One gray hair, two gray hairs.

"He's an old pervert!"

He was stunned, "What's too much?" ”

Zhao Lin changed his words and said: "I mean, the murderer is an old man. ”

"Yes!"

He nodded and said, "I estimate that my age is between fifty and sixty." ”

"I didn't expect ......"

Zhao Lin muttered to himself, recalling that Huang Xiangqin's father had grown his hair, and his hair would not be so short, so it seemed that it must have been left by the murderer.

"Good, anything else to discover?"

He stepped forward and whispered, "There are traces of invasion on the deceased's body, but it is still a virgin. ”

"Virgin?"

Zhao Lin was surprised, but he was quickly relieved: the more perverted he was, the more incompetent he was.

In the afternoon, Liang Song and the others returned to the county office, but they did not hear any useful news.

Zhao Lin felt a heavy burden on his shoulders, if the case could not be solved, his career as a fast catcher would probably come to an end.

Even if it wasn't for himself, he wanted to catch the murderer, this kind of person left in the world, and he didn't know how many ordinary people he would harm.

……

Zhao Lin has been staying in the fast room until the evening, and the files are about to be rotten, and he still has no clue.

"Go to bed early, and we'll go back tomorrow to see where the accident happened before."

Liang Song saw that Zhao Lin was so sleepy that he yawned, and persuaded on the side.

"It's fine."

Zhao Lin put down the file, went to the courtyard to wash his face, and lay on the bed with his clothes.

Just when he was about to fall asleep in a daze, he suddenly remembered a movie he had watched in his previous life about the corpse shredding case.

"There it is!"

Zhao Lin sat up with a spirit.

Liang Song was startled and asked, "What's wrong?" ”

"It's nothing, you sleep first."

Zhao Lin slowly calmed down and tried to recall the relevant plot in his mind.

The movie tells the story of a serial murderer who keeps killing people and committing crimes, and is finally arrested by the government.

In the movie, the detective uses a method called "geo-profiling".

Zhao Lin also deliberately searched for relevant entries on the Internet and learned that this is an investigation method specifically aimed at cases of serial homicide, rape, arson, robbery and so on.

The so-called geographical portrait is to list all the locations of the murderer on a map.

Analyze and study the spatial distribution and connection of these locations, find out the area where the murderer is located, and achieve the purpose of narrowing the scope of investigation.

This kind of detection method requires a lot of professionalism, and Zhao Lin is not an expert in this area, but he knows one of the easiest methods:

Find the two crime spots that are the farthest away and make a straight line.

Then draw a circle with this line as the diameter.

If the locations of the crimes are all in this circle, then the murderer is likely to settle in this area.

Zhao Lin fell asleep, lit the oil lamp, took out the map, and marked the file on the map.

The map of the county government is rough, but the scale is relatively accurate, and he found the two farthest places and drew a circle.

Sure enough, three other case points also fell into the circle.

"This circle is not small!" Zhao Lin muttered to himself in a low voice.

He visually measured the circle to be more than three miles in diameter and encompassed two populated areas and a densely populated market.

It is not easy to find the murderer in such a large area, Zhao Lin looked at the map for a long time and felt at a loss.

In a moment of boredom, he picked up a charcoal pen and connected the five dots in a straight line.

It is an irregular pentagram with a sideline of varying lengths and a small empty space in the middle.

When Zhao Lin's gaze fell on an address in the blank area, his eyes suddenly froze.

"It can't be such a coincidence, can it?"
