Hearing this, not only Ma Guozhen, but also the police officers at the scene were taken aback.

Professor Lin ...... What do you mean by ......

".

Ma Guozhen looked at Lin Can with some uncertainty.

"I just need a day. "

Lin Can said directly: "This case will be solved within one day, but on this day, you must fully cooperate with my actions." "

As soon as these words came out, the scene was in an uproar again.

Everyone looked at Lin Can beside Ma Guozhen with incredulous eyes.

This little-known foreign-aid professor dared to boast of such a Haikou after simply learning about the facts of the case.

This case will be solved in one day?

In the current situation where there is no progress in the case, even the top detectives in China dare not make such a false statement.

This so-called young professor can't be bragging, right?

Ma Guozhen looked at Lin Can on the side suspiciously, he was also unsure of the handsome young man next to him, not to mention that Lin Can's promise was too extreme, and it was indeed difficult to be convinced.

However, for now, they have no better way to solve the dilemma, so Ma Guozhen can only choose to believe Lin Can.

After weighing for a moment, Ma Guozhen nodded slowly, "You are a foreign aid professor specially invited by the director, so we will naturally fully cooperate with your investigation operation." "

"Good. "

Lin Can nodded, and at the same time looked at the pile of materials on the table, "I know the general content of the case, but this has been three cases in a row, did you find any valuable traces at the scene?"

Hearing this, Ma Guozhen's face became a little embarrassed.

"The murderer has a certain sense of anti-reconnaissance, and the places he chose to commit crimes are all blind spots or places without monitoring, and it was raining lightly at the time of the three crimes, and many traces ......of the crime have not been preserved."

Ma Guozhen coughed twice, "So far, we haven't been able to get any traces for the time being. "

Hearing this, Lin Can immediately had a general understanding of the criminal investigation level of the Z City Municipal Bureau.

Although the murderer has a certain anti-reconnaissance ability, unless the murderer is a top criminal with a strong IQ and an extremely good understanding of detective methods, it is impossible to carry out three crimes in a row in such a short period of time.

From the information that Lin Can learned before, it is obvious that the murderer is not a top-level criminal, as long as the investigation team with excellent professional standards can more or less find some clues.

However, the overall criminal investigation level of this world is much lower than the world before Lin Can's rebirth, so Lin Can was not very surprised.

"Okay, I see. "

Lin Can continued to look at the information on the table, and then continued to ask, "Have you investigated the identities of these three victims in detail?"

"Of course. "

Ma Guozhen said: "These three victims do not have any direct connection in terms of age, gender, occupation or kinship, so this is also the biggest obstacle we have encountered in tracking down the murderer. "

"Yes, we tried to find the link between the three victims at all levels, but in the end nothing came to naught. "

Lao Liu on the side continued: "The target chosen by the murderer is irregular, and we have no way of judging the murderer's motive for committing the crime. "

"You're wrong. "

Lin Can looked at the several photos of the victims on the projection and said, "It's not that there is no trace. "

Hearing this, Ma Guozhen and Lao Liu both turned their heads to look at Lin Can with a curious expression.

Did he find out so quickly?

Lin Can was silent for a while, and then slowly spoke: "The three victims all have one thing in common, they are all very thin. "

Hearing this, Ma Guozhen and Lao Liu both looked at each other.

What kind of discovery is this?

"That alone doesn't mean anything, but look at these photos of the crime scene. "

Lin Can analyzed: "The skin on the edge of the victim's severed limb is erosive, and the cut surface of the severed limb is rough, which is a trace of repeated chopping, which shows that the murderer's strength is not great, so it is necessary to chop the victim's arm repeatedly." "

And from the perspective of limb sections, the murderer has been using his left hand to swing the axe with one hand, which indicates that his right hand may be disabled. "

"Combined with the size of the three victims, it is not difficult to tell that the murderer may have been a woman, or a man who was not strong. "

However, the height of the first victim, Yang Jundong, was 175cm, and the murderer was able to easily stun him from behind, indicating that his height would not be less than 1.7 meters. "

Lin Can said: "Therefore, the murderer is most likely an adult male and has a disabled arm, so the targets he chooses to commit crimes are relatively thin." "

"You go on!".

Ma Guozhen's eyes lit up on the side, Lin Can's analysis was reasonable and well-founded, obviously professional enough!

"Choosing an unmonitored, rainy and sparsely populated place to commit the crime, and taking the initiative to clean up the traces of the crime scene, shows that the murderer has a certain sense of anti-reconnaissance and has been prepared before committing the crime, which is a typical premeditated crime. "

Lin Can said: "Knowing the situation on each road and clearly understanding which places are not monitored shows that the murderer is most likely a local and lives not far from the location of the three crimes." "

"As for the murderer's motive ......".

Lin Can's eyes narrowed, and then he said to Ma Guozhen on the side: "Captain Ma, I need more detailed information about these three victims, including their family financial bills and all their personal contacts in recent years. "

"No problem. "

Ma Guozhen immediately said to Lao Liu on the side: "You immediately bring someone over to investigate, and sort out these materials as soon as possible." "

"Yes!".

Lao Liu responded, and then immediately left the conference room with several police officers.

"In addition, I need a detailed map of City Z. "

Lin Can said.

"No problem, as a detective, we always carry a map with us. "

Ma Zhenguo snapped his fingers at the scene, and immediately a police officer took a few maps and handed them to Lin Can.

"Good. "

Lin Can took the map, then found the road where the three crimes occurred, circled them, and marked a few lines on the side.

Ma Guozhen and the others looked at Lin Can's movements and asked seriously, "Professor Lin, what do you need us to do next?"

Lin Can put down the pen and map in his hand, "You all rest and rest next, go eat something if you haven't eaten, and go to sleep for a while if you should sleep." "
