The dark red metal card that Luo An took out was the identity document obtained after capturing the taxi driver who had sneaked into Luo An's villa and tried to find the cross.

Seeing the dark red metal card, Lacey's eyes lit up, and Mona sat up straight, refreshed, and asked with a smile:

"Ann, you're going to use that underworld crime site to find clues?"

"That's right."

Luo An smiled and nodded, handed a notebook to Mona, and said:

"It's not just this website, it's the crime site we met earlier, and I've borrowed several identities from the Ministry of Intelligence."

"Wow."

Mona took the notebook and sighed, looked down a few times, and said with some surprise:

"Eight crime sites? Why so many? ”

"The development of the Internet is changing with each passing day, and the underground world naturally has long-term talents, and the Ministry of Intelligence has been dealing with these things, and there are not many criminal websites in the eight worlds."

Luo An smiled, this morning he called the intelligence department to ask for help, he thought that it was really impossible to let Verenis come forward, but he didn't expect the intelligence department to hear his name, and agreed without saying a word.

The Ministry of Intelligence not only directly handed over all the eight criminal websites on hand to Luo An, but even prepared three or four accounts for Luo An with disguised identities for each website.

Luo An was very surprised to get this information, and only after asking did he learn that the Ministry of Intelligence had also heard about the investigation team led by Luo An, and the 100% detection rate of the case.

This time, knowing that Luo An needed help, the Intelligence Department was naturally willing to push the boat down the river to send personal favors.

Briefly thanking the intelligence department, Luo An's expression turned cold after hanging up the phone.

It's a good thing to get the help of the Ministry of Intelligence, but the fact that the crime solving rate behind the scenes is being publicized, coupled with the phone call from Verenis before, makes Luo An smell that something is wrong.

So Luo An called Verenis again later, and after a brief communication, Verenis immediately agreed and prepared to deal with this matter.

Putting these things behind for the time being, Luo An briefly said some precautions, and Mona then took the computer and notebook, pulled Michelle out of the conference room, and began to enter those websites to post tentatively to investigate.

The second daughter left the conference room, and Luo An then looked at the other agents left behind and asked:

"Guys, how are the clues of the first serial murder case, that is, the case against the shape worker?"

"An important clue has been found."

Hearing Luo An's question, the detectives immediately turned their attention to the first serial murder case, rummaging through the documents in their hands for a moment, Winslow stood up first and said:

"During the investigation, we found that among the 12 victims of the first serial homicide case, the first victim died in 1992, which was too early to find relevant information, and the second, third, fourth, and fifth victims were also difficult to investigate due to similar circumstances.

In addition to these five victims, after the death of the next seven victims, one of their family members or a friend has received a call from someone using the victim's mobile phone.

The content of the phone call is roughly the same, all of which are the murderer's claim that he has forced* and killed the victim, and even the murderer will describe his feelings, etc., causing the victim's relatives or friends to scold. ”

“Fu-k！”

Lacey scolded in a low voice, and Anne Mori, a profiler from the Behavior Analysis Department next to her, nodded and said in a deep voice:

"This is a clear act of provocation, which on the one hand shows that the pleasure of killing others for the killer has gradually decreased, and the murderer has begun to look for more pleasure from the victim's relatives or friends.

On the other hand, it also shows that the murderer is very confident in his safety, he believes that he has erased the clues related to him, and firmly believes that the law enforcement officers cannot find him. ”

"A very rampant guy."

Luo An's eyes narrowed slightly, and then asked:

"Did you find a clue on your phone?"

"Some, but not much."

Winslow handed Roan a folder and explained:

"According to the investigation, when the murderer made the call, he used the victim's mobile phone.

Based on the location of the signal, we found a total of three base stations, and it was determined that the killer was in a park on Long Island when he called.

But there is no use of information in the follow-up, because there is no monitoring in that park, there is still a lot of traffic, and there are so many men who match the simulated portrait made by Anne's profiler that it is impossible to check all of them. ”

Luo An looked at the information in the folder and asked:

"Have you checked the call logs of these 7 victims' mobile phones? There are no suspicious disposable calls, or anonymous calls. ”

"I've checked it, but I haven't done it."

Winslow shook his head and said:

"I suspect that this murderer used the most old-fashioned method, that is, to go to the street and randomly find women who are engaged in physical work, and then use money to trick them into going with him."

"It's a problem."

Hearing this, Lacey's brows tightened, and she said:

"New York is so big, and there are probably more than 100,000 women engaged in physical work.

Excluding those who are organized, led by gangs, and those who work alone on the streets, the number is probably more than 10,000.

If the murderer really used the old method of driving on the street to find random people, according to his annual killing frequency, we may not be able to find him at all. ”

Luo An clasped his hands in front of his chest and was silent, Chenelle thought for a moment and asked:

"What if we also use the stupid method and ask those women one by one?"

"It's impossible."

Lacey shook her head again and again, and introduced:

"You don't know about this industry, it's a lot of people.

If a woman is willing to work hard, it is not a problem to receive a dozen guests in a night, after all, most men are very fast.

In addition, the turnover of people in this industry is far beyond your imagination.

In addition to those permanent workers, there are also many women who work temporarily for a few days because of lack of money, after all, this industry does not require any technical accumulation.

There are also women who stay in one place for a few days and then run off to work elsewhere because they are threatened or afraid of being seen by acquaintances.

All of these circumstances add up to make it difficult to find all the women.

Even if they find it, they have come into contact with so many men, and they probably can't remember the appearance of a specific man, and at most they have a little impression of the time and length of a certain man. ”

“……”xN

Listening to Lacey's serious science popularization and explanations, Chenellele and Anne-Mo are full of black lines.

Winslow looked at Lacey with a bad look, and he felt that Lacey's remarks about time seemed to insult him.

Luo An, who was also a man present, glanced at Lacey quietly, took the folder and gently tapped her head, and then asked:

"Do you have any suggestions for how we should investigate next?"

Lacey patted the folder on her head, waved her finger and said:

"The murderer was very cautious and did not use his mobile phone to contact these victims, so the mobile phone did not work.

Ask directly on the street, we may not be able to find clues after a year of investigation.

So...... Either we will refer this case to another investigation team. ”

Luo An retracted the folder, nodded, and said:

"Your suggestion is very good, don't suggest it next time."

Lacey: "......"

Glancing at Lacey, who rolled her eyes at Roan, Chenelle frowned:

"Both roads are blocked, team leader, what are we going to do next?"

"I have an idea."

Luo An groaned for a while, and was just about to speak, when the door of the conference room was suddenly opened, and Mona walked in with a laptop and said excitedly:

"Guys, Michelle and I found an interesting post!"
