Legendary FBI Detective-Chapter 252: The Zero Patient with HIV

"Exactly!"

Luo An nodded. According to his colleague Lena's explanation, Flavia Fran was actually close to finding out who the original infected person was, and the specific details and the method to find that person were in that notebook.

So, if the murderer really wanted to find the original infected person, they could totally do so with that notebook.

Just then, Mona's shout suddenly came:

"Everyone, I found that guy's shadow!"

Luo An and Reesi hurried over to Mona's side, where a short surveillance video was playing on the computer.

A person riding a bicycle, holding a notebook and occasionally flipping through it to write and draw, sneakily followed behind Darrell Roger.

However, due to insufficient skills, they were easily spotted by Darrell Roger, who had honed his talents in prison, causing them to quickly change the direction of the bicycle and speed away.

The surveillance footage, however, was not very clear, and due to the bike rider wearing a hood and a mask, Mona and the others couldn't see the rider's face.

But they weren't without a lead. As the person on the bicycle rode away, they exposed their white wrist, which allowed Luo An and the team to accurately identify the person as a white federal individual.

"And this guy seems pretty young."

Mona tapped a few keys on the keyboard and zoomed in on the white person's bike in the video, showing it to be a rather fancy bicycle.

Reesi puckered her lips at this sight, and Luo An then asked:

"Is there any way to find out who bought this kind of bike?"

"No way to find out."

Mona shook her head. These types of bikes were very popular among young people and were seen everywhere in New York. There were countless reports of these bikes being stolen submitted to the NYPD.

Luo An's expression didn't change, and he was not affected negatively by Mona's words. He then clapped his hands strongly, attracting the attention of all the agents of the Number Five Investigation Team before asking loudly:

"William, you haven't found the second victim in the people recorded by Flavia yet, have you?"

"That's correct."

William nodded, then indicated that they found the people listed in those two folders somewhat incomplete, with some information likely contained in Flavia Fran's notebook which Flavia hadn't had the chance to sort out yet.

Luo An felt that William's suspicions were very likely correct, then briefly reiterated the analysis he had with Reesi and continued:

"The murderer is very likely seeking the original Mr. Zero HIV-infected person now, and this person is his next target.

So, what we need to do next is to find this Mr. Zero infected person before the other party does, and then figure out a way to catch the murderer who killed Flavia Fran, whether it be by lying in wait or some other method!"

"No problem!"

The source of this c𝐨ntent is freёnovelkiss.com.

The eyes of the members of Investigative Team Five brightened as they heartily agreed to the task. As soon as Luo An finished talking, William and the other technical agents immediately sprang into action.

Laying out the information of everyone in the folder side by side, Luo An quickly discovered Flavia's investigative method, which was to examine who each person had sexual relations with.

After all, sexual relations are one of the main ways the AIDS virus spreads rapidly.

After starting the investigation with this approach... the members of Investigative Team Five began to understand what true freedom felt like.

One of the women, a Caucasian named Inka, had a list of male sexual partners from a short period that was almost large enough to form two soccer teams.

If it weren't for Flavia's investigation revealing that her HIV was contracted from someone else, Luo An and the others would have almost believed she was the patient zero carrier of the virus.

By linking these people with arrows, Investigative Team Five quickly identified three individuals from whom the arrows did not point to anyone else, so the next targets naturally became finding other people who had sexual relations with these three individuals.

Because there weren't many people, Luo An and Mona paired up, Reesi went alone, and Laide went alone, to search for these three filtered-out individuals.

Laide, who had just returned to Investigative Team Five and had barely sat down, said: "..."

"So, this is actually an AIDS epidemic, right?"

Upon arriving at the first target person's community, Mona stepped out of the passenger side, looking at Luo An speechless.

"That could be said."

Luo An nodded; the case had been sorted out, and the overall content was not complicated:

A person initially infected with the AIDS virus acted with no public conscience, not only refraining from seeking treatment and concealing the fact that they were diseased but also frequently changing sexual partners.

After these sexual partners contracted AIDS, they then had relations with others, further transmitting the virus to more people, multiplying it from one to ten and directly from ten to a hundred.

The murderer who killed Flavia Fran was just a pitiful member of this "hundred."

Mona smacked her lips, then knocked on the door of the first source individual's home.

This source was a high school student by the name of Barry.

"So why didn't you use protection in the first place?"

Luo An was genuinely curious, as he remembered that many federal schools provide students with free contraception.

"Because I'm Catholic."

Barry shrugged; young people always have their unique rationale:

"Additionally, I joined an environmental club at our school, one of whose core principles is anti-rubber."

Luo An: "...Six."

Thanks to their FBI status, Luo An and Mona easily got from Barry the name of the person who transmitted the HIV to him, unsurprisingly a female, who also lived nearby.

This female was named Wen Xian, quite young, with good looks and figure, but she had a husband who liked to engage in extramarital affairs, so under various dissatisfactions, Wen Xian also started her own affair spree.

Upon learning Luo An and Mona's purpose, Wen Xian struggled a bit at first but ultimately revealed a man's name: Matthew Ethan.

Just after leaving Wen Xian's house, Reesi and Laide both called Luo An, indicating that they had also come across the name Matthew Ethan.

"Good."

Hanging up the phone, Luo An turned to look at Mona beside him:

"It seems this gentleman is the unethical Mr. Zero.

How about it, can you locate where this guy is now?"

"Quite easily."

Returning to the SUV passenger side, Mona opened her laptop and started tapping away, quickly finding the suspect's current location:

"Queens Saint John Hospital!"

Upon hearing this, Luo An furrowed his brows:

"Hospital?"
