This was the question that Li Ze had to think about.
If he could figure it out in a short period of time, he might be able to immediately lock onto the suspect's identity.
Gelofang was a controlled medicine.
Of course, it wasn't an absolute ban.
There were three requirements.
First, a small amount.
Second, real name registration.
Third, explain the purpose.
These three conditions had to be met at the same time before he could purchase it.
However, no matter what, it was impossible for the murderer.
A small amount?
To kill four people in a row, and by injection, that would require a large amount of pheromone.
Real name registration?
It would be better to kill someone and turn himself in at the police station.
Explain its use?
How should he explain it? Kill someone?
"Wu Kang, how's your investigation on this?”
Li Ze looked at Wu Kang and asked.
There was no record of it in the dossier.
Thinking about it, the investigation should have been fruitless.
However, he still had to ask what he needed to ask.
At the very least, he had to know how far the other party's investigation had progressed.
Wu Kang was silent for a moment before he said,""Captain, we are still investigating.”
As the vice-captain of the criminal police, although he was not as capable as Li Ze, he still had some common sense.
The victim had been poisoned by the drug, and since it was a controlled drug, the source had to be investigated.
After all, there weren't many industries that could be used for this.
There were also very few people who bought it.
As long as he investigated, he would get the results very quickly.
However, he had sent people to all the pharmaceutical shops in the city, but they did not find anything.
None of the buyers knew the four victims.
Furthermore, its usage was very standard and there was no problem with it.
As for the internet, he had not found any traces of the drug being sold.
That was illegal.
"Are you sure you didn't miss anything?" Li Ze asked.”
"As long as it's a registered pharmacy, I'll definitely not miss anything." Wu Kang straightened up and nodded.”
Li Ze stared at it for a while, causing the latter to feel a little scared.
After a while, he chuckled and said,"If that's the case, I'm afraid the scope of suspects will be narrowed again."”
"There aren't many people who can easily obtain something like this…"
Wu Kang blinked as if he suddenly remembered something. He frowned but didn't say anything immediately.
"There should be chemical plants, hospitals, and even universities of science and technology.”
"If you want to steal it, it's not difficult.”
Hearing this, Li Ze nodded." That's right. The murderer wouldn't be so stupid. He would really go to the store to buy it. He's just ruling out one possibility."”
"Since Wu Kang has checked the list, there are only two ways for the murderer to obtain the pheromone.”
"Two?"
Fu Xiaojun was moved.
Other than stealing, was there a second possibility?
"First, steal."”
"As for the second…"
"Make it yourself."
The last four words made Fu Xiaojun understand.
He had almost forgotten about this.
Although the possibility was not very high, it was not completely impossible.
"If it was stolen…"
Li Ze muttered to himself and turned to look at the big screen.
"Tong Xuan, get the addresses of the chemical factories and major hospitals in the city, as well as the comprehensive universities.”
Investigating a case was a complicated process and had to be done step by step.
If one was afraid of trouble, one would not be able to become a qualified criminal police officer.
"Alright."
Tong Xuan nodded and started to work on the computer.
Soon, the entire map changed.
All the dots lit up at the same time.
Li Ze took a glance and could not help but take a deep breath.
It was too much.
If he were to investigate them one by one, he would need at least ten days to half a month to obtain satisfactory results.
If he could find someone who was connected to a certain place…
Thinking of this, he turned around and said,"Increase the scope of the investigation."”
"The targets of the investigation are not limited to the relatives and friends of the deceased.”
"As long as they know each other, have met each other, or have interacted with each other, they are all under investigation.”
"The main point is women between the ages of 25 and 35.”
"As long as you find a suspicious person, first confirm the alibi. Be careful to prevent the illusion from taking advantage of the loophole!”
Nowadays, there were too many ways to forge an alibi.
The development of science and technology had brought about a qualitative breakthrough in criminal investigation techniques.
At the same time, it also brought a new pattern to criminal methods.
"Yes!" Everyone nodded in unison. Captain!"
Li Ze looked at Song Shirou and said," Shirou, it's been hard on you. Let's do a full autopsy and see if there are any new clues."”
"Don't worry, Captain. Leave it to me."”
After issuing a few orders, Li Ze fell into deep thought.
As for what he was thinking, no one knew.
The meeting room fell silent.
At this moment, Wu Kang, who had been frowning, seemed to be distracted.
His eyes widened as he listened to Li Ze's words.
He easily obtained the pheromone?
Stealing?
Forging an alibi?
Female?
Move to the local area?
A few clues flashed through his mind, and Wu Kang immediately let out a strange cry.
"Ah!"
This shout was extremely sudden, giving everyone a shock.
Even Li Ze, who was deep in thought, raised his head and looked at Wu Kang suspiciously.
Fu Xiaojun, who was the closest, was the most affected.
"Wu Kang!!" she shouted angrily. Are you crazy?"
"I think of a major suspect!" Wu Kang stood up abruptly and said.!”
As soon as he said this, the entire place fell silent.
