Legendary FBI Detective

The dark red metal card that Luo An took out was the identity credential obtained after he captured the taxi driver who 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 upright, refreshed, and asked with a smile:

"Luo An, do you plan to use that criminal website in the underground world to look for clues?"

"That's right."

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

"Not just this website, I also borrowed several identities from the Intelligence Department for the criminal websites we met earlier."

"Wow."

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

"Eight criminal websites? Why so many?"

"The Internet is developing at a rapid pace, and the underground world naturally has talents with long-term vision. The Intelligence Department has been dealing with these matters. Eight criminal websites are not many."

Luo An smiled. He called the Intelligence Department this morning to ask for help. He thought that if it was not possible, he would ask Veranith to come forward. Unexpectedly, the Intelligence Department heard his name and agreed without saying a word.

Not only did the Intelligence Department directly hand over all eight criminal websites on hand to Luo An, they even prepared three or four accounts for Luo An to disguise their identities.

Luo An was very surprised to get this information. After asking, he learned that the Intelligence Department also heard about the investigation team led by Luo An, which had a 100% case detection rate.

Knowing that Luo An needed help this time, the Intelligence Department was naturally willing to give him a favor.

After simply expressing his gratitude to the Intelligence Department, Luo An's expression turned cold after hanging up the phone.

It was a good thing to get help from the Intelligence Department, but the fact that the crime detection rate was publicized behind the scenes, coupled with Veranith's previous phone call, gave Luan a smell that something was wrong.

So Luo An later called Veranith and communicated briefly for a while. Veranith immediately agreed and was ready to handle this matter.

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

The two women left the conference room. Luo An then looked at the other agents who were left behind and asked:

"Everyone, how is the investigation going on with the clues for the first serial murder case, which is a case against a sex worker?"

"Important clues found."

After hearing Luo An's question, the detectives immediately turned their attention to the first serial murder case and rummaged 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 in the first serial murder case, the first victim died in 1992, which was too early to find relevant information. The second, third, fourth and fifth victims were Due to similar circumstances, relevant information is scarce and difficult to investigate.

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

The content of the phone calls was roughly the same. The murderer claimed that he had raped and killed the victim. The murderer even described his feelings, which caused the victim's relatives or friends to curse. "

"Fu-k!"

Lacey cursed in a low voice, and Anne Murray, a profiler from the behavioral analysis department next to her, nodded and said in a deep voice:

"This is a clear provocation. On the one hand, it shows that the pleasure brought to the murderer by killing others has gradually decreased, and the murderer has begun to seek more pleasure from relatives or friends of the victim.

On the other hand, it also shows that the murderer is very confident in his own safety. He believes that he has eliminated the clues related to himself and firmly believes that law enforcement officials cannot find him. "

"A very arrogant guy."

Luo An narrowed his eyes slightly and then asked:

"Have you found any clues about the mobile phone?"

"We found some, but not many."

Winslow handed a folder to Roan and explained:

“According to the investigation, the murderer used the victim’s mobile phone when making calls.

Based on the location where the signal came out, we found a total of three base stations, and we can determine that the murderer was in a park on Long Island when he made the call.

But the information was useless later because there was no surveillance in the park and the flow of people was still very large. There were so many men who matched the simulated portraits made by Annie's profiler that it was impossible to investigate them all. "

Luo An looked at the information in the folder and pondered for a while, then asked:

"Have you checked the call records of these seven victims' mobile phones? Are there any suspicious disposable calls or anonymous calls?"

"I've checked and found none."

Winslow shook his head and said:

"I suspect that this murderer used the most old-fashioned method, that is, he went to the streets to randomly find women who were engaged in illegal work, and then used money to trick them into following him."

"This is very troublesome."

Lacey frowned when she heard this and said:

“New York is as big as New York, and there are probably hundreds of thousands of women working in the nude industry.

Excluding those who are organized, have gang leaders, and those who work alone on the streets, the number is probably over 10,000.

If the murderer really used the old method of driving on the streets to find random people, based on his murder frequency of once a year, we might not be able to find him at all. "

Luo An crossed his arms on his chest and remained silent. Cheniel thought for a while and asked:

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

"Totally impossible."

Lacey shook her head repeatedly and introduced:

“You don’t understand this business, there’s a lot of traffic in this business.

If a woman is willing to work hard, it is not a problem to receive more than a dozen customers in one night. After all, most men are very fast.

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

In addition to those regular workers, there are also many women who work temporarily for a few days due to lack of money. After all, this industry does not require any accumulation of skills.

There are also women who stay in one place for a few days and then go to work elsewhere because they are threatened or worried about being seen by acquaintances.

These circumstances combined make it difficult to find all women.

Even if they find it, they have been in contact with so many men, and they will most likely not be able to remember the appearance of a specific man. At most, they have some impression of the time and duration of a certain man. "

"..."xN

Listening to Lacey's serious science popularization and explanation, Chenelle and Annie-Mo's heads were full of dark things.

Winslow looked at Lacey with a slightly unkind look. He felt that Lacey's statement about time just now seemed to insult him.

Luo An, who was also a man present, glanced at Lacey calmly, tapped her head lightly with the folder, and then asked:

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

Lacey patted the folder on her head, waggled her fingers and said:

“The murderer was very cautious and never used mobile phones to communicate with these victims, so the mobile phone route was not feasible.

If we go directly to the streets and ask questions, we may not be able to find any clues for a year.

So... how about we hand this case over to other investigation teams. "

Luo An took back 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 Luo An, Chenelle frowned:

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

"I have an idea."

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

“Guys, Michelle and I found an interesting post!”
