Hearing this, not only Ma Guozhen, but all the police officers at the scene were shocked.
"Professor Lin…what do you mean…"
Ma Guozhen looked at Lin Can with uncertainty.
"I only need one day."
"I'll solve this case within a day, but within this day, you must fully cooperate with me."”
As soon as he said this, the scene was in an uproar again.
Everyone looked at Lin Can, who was beside Ma Guozhen, in disbelief.
This unknown foreign aid professor dared to make such a big promise after he had a simple understanding of the case.
He would definitely solve this case within a day?
In the current situation where there was no progress in the case, even the top detectives in the country did not dare to make such a claim.
Was this so-called young professor bragging?
Ma Guozhen looked suspiciously at Lin Can. He was also not confident about this handsome young man beside him. Moreover, Lin Can's promise was too extreme and it was indeed difficult to convince him.
However, for now, they did not have a better way to solve the predicament, so Ma Guozhen could only choose to believe Lin Can.
After weighing the pros and cons for a moment, Ma Guozhen slowly nodded." You are a foreign aid professor specially invited by the director. We will naturally cooperate with your investigation.”
"Very good."
Lin Can nodded as he flipped through the stack of documents on the table." I have a rough understanding of the contents of the case, but there have been three consecutive cases. Did you find any valuable traces at the scene?”
Hearing this, Ma Guozhen's expression turned awkward.
"The murderer has a certain degree of anti-reconnaissance awareness. The crime locations he chose were all blind spots or places without surveillance cameras. Moreover, it was drizzling when the three crimes were committed, so many traces of the crime were not preserved…"
Ma Guozhen coughed twice." So far, we haven't been able to obtain any traces.”
Hearing this, Lin Can immediately had a general understanding of the criminal investigation standards of City Z's municipal bureau.
Although the murderer had a certain degree of anti-reconnaissance ability, unless the murderer was a top criminal with a high IQ and a deep understanding of detective methods, it was impossible for him to commit three crimes in such a short period of time without leaking any information.
From the information that Lin Can had previously learned, it was obvious that the murderer was not a top-notch criminal. As long as the professional investigation team was strong, they would more or less be able to find some clues.
However, the overall level of criminal investigation in this world was much lower than the world before Lin Can's rebirth, so Lin Can was not very surprised.
"Alright, I got it."
Lin Can continued to flip through the information on the table, then continued to ask,"Have you investigated the identities of the three victims in detail?”
"Of course."
"There is no direct connection between the three victims in terms of age, gender, occupation, or kinship, so this is the biggest obstacle we have encountered in tracking down the murderer."”
"Yes, we tried to find the connection between the three victims from all levels, but in the end, we found nothing.”
" There's no pattern in the murderer's target selection," Old Liu added." We have no way of determining the murderer's motive."”
"You are wrong."
Lin Can looked at the photos of the victims on the projection and said," It's not untraceable.”
Hearing this, Ma Guozhen and Old Liu turned to look at Lin Can curiously.
Could it be that he had discovered something so quickly?
Lin Can was silent for a while, then slowly said,""The three victims all have one thing in common. They were all very thin.”
Hearing this, Ma Guozhen and Old Liu looked at each other.
What kind of discovery was this?
"This alone doesn't explain anything, but take a look at these photos of the crime scene.”
Lin Can analyzed." The skin on the edge of the victim's severed limb was rotten, and the cut surface of the severed limb was rough. This is the mark of repeated hacking. This shows that the murderer's strength was not strong, so he had to chop the victim's arm repeatedly.”
"And from the perspective of the body, the murderer has been using his left hand to swing the axe with one hand, which means that his right hand may be disabled.”
"Combined with the three victims 'figures, it's not difficult for us to determine that the murderer might be a woman or a man who is not strong.”
"However, the first victim, Yang Jundong, was 175cm tall. The murderer was able to easily knock him out from behind, which means that he was no less than 1.7 meters tall.”
"So the murderer is most likely an adult male with a disabled arm," said Lin Can."Therefore, the targets he chose are relatively thin.”
"Continue!"
Ma Guozhen's eyes lit up. Lin Can's analysis was reasonable and professional enough!
" Choosing to commit the crime in a place without surveillance cameras, rainy days, and sparsely populated, and taking the initiative to clean up the traces of the crime scene, this shows that the murderer has a certain degree of counter-reconnaissance awareness, and he was already prepared before committing the crime. It's a typical premeditated crime.”
" Understand the situation of each road and clearly understand where there are no surveillance cameras," Lin Can said." This means that the murderer is likely a local and lives not far from the three crime scenes."”
" As for the murderer's motive…"
Lin Can narrowed his eyes and said to Ma Guozhen,"Captain Ma, I need more detailed information about these three victims, including their family financial bills and all their human relationships in recent years.”
"No problem."
Ma Guozhen immediately said to Old Liu,"Bring some people over to investigate immediately and bring this information over as soon as possible.”
"Yes, sir!"
Old Liu responded and immediately left the meeting room with a few police officers.
"Also, I need a detailed map of City Z.”
Lin Can said.
"No problem. As criminal investigators, we always carry a map with us.”
Ma Zhenguo snapped his fingers at the scene. Immediately, a police officer handed a few maps to Lin Can.
"Very good."
Lin Can took the map and found the roads where the three crime scenes were located. He circled them and marked a few lines beside them.
Ma Guozhen and the others looked at Lin Can's actions and asked seriously,"Professor Lin, what do you need us to do next?”
Lin Can put down the pen and map in his hands." All of you should rest. Those who haven't eaten, go and eat something. Those who should sleep, go and sleep for a while.”
