Luo An took out a dark red metal card, which was the identity proof obtained after catching the taxi driver who sneaked into Luo An's villa, attempting to search for the cross.
Seeing the dark red metal card, Reesi's eyes lit up, and Mona sat up straight, her spirits lifted as she asked with a smile:
"Luo An, are you planning to use that underworld crime website to look for clues?"
Luo An nodded with a smile and handed a notebook to Mona, saying:
"Not just that one website, but also earlier crime websites we've encountered. I have borrowed several identities from the intelligence department."
Mona took the notebook with astonishment, glanced at it briefly, and said somewhat in surprise:
"Eight crime websites? Why so many?"
"The development of the internet is rapidly changing, and the underworld naturally has forward-thinking talents. The intelligence department has been handling these matters all along, and eight websites is not that many."
Luo An laughed, thinking back to this morning when he called the intelligence department for help. He originally thought that if worse came to worst, he'd ask Vireness to intervene. However, when the intelligence department heard his name, they agreed without a second word.
The intelligence department not only handed over all eight crime websites they had on hand to Luo An but also prepared three or four decoy identities for each website.
Luo An was surprised when he received this information. After inquiring, he learned that the intelligence department had also heard of the investigation team led by Luo An, with its 100% case-solving rate.
Once they knew Luo An needed help, the intelligence department naturally wanted to lend a helping hand by doing a favor.
After simply expressing his gratitude to the intelligence department, Luo An hung up the phone, his expression turning cold.
Getting help from the intelligence department was a good thing, but the fact that his case-solving rate had been publicized, along with the previous call from Vireness, made Luo An sense something was amiss.
So, he made another call to Vireness, had a brief discussion, and she immediately agreed to handle this matter.
Putting these matters aside for the time being, Luo An gave some precautions and Mona, along with Michelle, took the computer and notebook, leaving the conference room, and began to enter those websites to post and probe for investigation.
After the two women left the conference room, Luo An turned to the remaining agents and asked:
"Ladies and gentlemen, how's the investigation into the first serial killing case, the one targeting professionals, coming along?"
"We have found important clues."
Upon hearing Luo An's question, all the agents immediately focused on the first serial killing case and after flipping through their files for a moment, Winslow stood up first and said:
"In our investigation, we found among the 12 victims of the first serial killing case, we couldn't find relevant information for the first victim due to their death occurring in 1992, being too far back in time. The second, third, fourth, and fifth victims were also difficult to look into because of the same issue, with scant related information.
Aside from these five victims, the relatives or a friend of the later seven victims all received calls from someone using the victims' cell phones after they died.
The content of the calls was roughly the same, with the perpetrator claiming to have assaulted and killed the victim, even describing his own feelings and other details, inciting curses from the victims' families or friends."
Reesi cursed under her breath while the behavior analysis specialist side profiler, Annie Mori, nodded and said in a serious tone:
"This is a clear act of provocation. On one hand, it suggests that the pleasure the killer gets from taking a life has gradually diminished, and he begins to seek more thrills from the victims' relatives or friends.
On the other hand, it also shows that the killer is very confident about his safety. He believes he has erased any clues related to himself, convinced that law enforcement won't find him."
"A very arrogant guy."
Luo An's eyes narrowed slightly, then he asked:
"Any clues found regarding the phone?"
"Some, but not many."
Winslow passed a folder to Luo An, explaining simultaneously:
"According to the investigation, the perpetrator used the victims' cell phones to make the calls.
Based on the signal broadcast locations, we've identified three cell towers, which confirms the perpetrator made the calls from a park on Long Island.
But there are no leads beyond this, as that park has no surveillance and a large influx of people. Many men matching the profile drawing by specialist Annie are present, making it impossible to check everyone."
Luo An looked at the information in the folder and pondered for a while before asking:
"Have the cellphone records of these 7 victims been checked? Are there any suspicious one-time calls or anonymous calls?"
"We've already checked, there aren't any."
Winslow shook his head and said:
"I suspect the perpetrator uses the most clichéd method, which is to pick up those women working in the sex industry on the streets at random, and then deceive them with money to follow him."
"That'll be troublesome."
Reesi frowned upon hearing this and said:
"New York is so big, there must be hundreds of thousands of sex workers.
Excluding those organized or gang-led, the number of independents on the streets must also be over ten thousand.
If the murderer really uses the old method of driving around to pick people at random, given his once-a-year killing frequency, we might never find him."
Luo An crossed his arms in front of his chest and remained silent. Chenier thought for a moment before asking:
"What if we use a blockheaded method and ask those women one by one?"
Reesi kept shaking her head and explained:
"You don't understand this business; there's a lot of turnover.
A woman who's willing to put in the effort can serve more than a dozen clients in one night; after all, most men are quick.
Also, the turnover rate in this business is far beyond your imagination.
In addition to the regular workers, there are also many women who do it temporarily for a few days when they're short on money, after all, no special skills are required.
Some women stay in one place for a few days, and then move to another area to work because they feel threatened or are afraid of being recognized by acquaintances.
All these factors combined make it difficult for us to find all the women.
Even if we found them, given the many men they encounter, they are likely to not remember the specifics of any particular man; at most, they'll have some vague memory of the time spent and whether it was brief."
Listening to Reesi's serious science lecture and explanation, Chenier and Annie Mori were covered in sweat.
Winslow, who looked at Reesi with a hint of disapproval, felt like her recent comment about time was a bit insulting.
Luo An, who was also a man, glanced at Reesi without a word, tapped her head lightly with the folder, and then asked:
"Do you have any suggestions on how we should proceed with our investigation?"
Reesi swatted the folder away from her head and said with a hand gesture:
"The perpetrator is cautious and didn't use a cellphone to contact these victims, so the cellphone route won't work.
Directly asking on the streets, it could take us a year to find any leads.
So... how about we hand this case over to another investigative team?"
Luo An took back the folder, nodded, and said:
"Your suggestion is quite good, don't make any more."
After glancing at Reesi rolling her eyes at Luo An, Chenier, with a furrowed brow, said:
"Both avenues are blocked, team leader, what do we do next?"
Luo An was about to speak after a moment of contemplation when the conference room door suddenly opened. Mona came in carrying a laptop, excitedly saying:
"Everyone, Michelle and I have found an interesting post!"
