In the future chat group, I'll become the richest man by just eating gossip.

Chapter 15 Feng Nan's Investigative Approach
Early the next morning!
When Feng Nan arrived at the Major Crimes Unit, Yue Yang and Li Biao were already waiting for her there.

Looking at the heavy dark circles under their eyes, Feng Nan knew that these two pillars of the Major Crimes Unit had been working through the night again on the Nine Corpses and Thirteen Heads case.

It wasn't that she arrived late; it's that these two hadn't gone home at all.

"Feng Nan is here?"

"Tell me, what did you find?"

Upon seeing Feng Nan, Yue Yang asked.

Feng Nan smiled and shared the breakfast she had bought on the way with Yue Yang and Li Biao: "You two haven't eaten yet, have you? Come on, let's eat and talk."

Yueyang and Li Biao didn't stand on ceremony with Feng Nan either.

He accepted his share, thanked her, and ate while waiting for Feng Nan and the rest of the story to continue.

Feng Nan didn't keep them in suspense. After organizing her thoughts, she said, "I've read through the materials and autopsy report that Team Leader Yue sent me yesterday. I feel like there's something wrong, but I can't quite put my finger on it. So I'd like to go back to the scene where the body was found and take another look. Maybe I'll find the answer I'm looking for there."

At this point, Feng Nan paused and looked at Yue Yang and Li Biao.

"You called me so early in the morning just for this?"

Yueyang put down the steamed bun in his hand and looked at Feng Nan with a puzzled expression.

"Of course not, but if this question isn't answered, anything I say afterward is just empty talk."

Feng Nan said helplessly.

Yueyang took a sip of soy milk: "You can go to the event, but before you go, tell me about your empty talk."

Li Biao, who was standing to the side, nodded with a smile: "That's right, let's talk about it first, anyway, we'll have to wait a while before we eat."

Looking at the two men with their ambiguous smiles, Feng Nan shook her head helplessly. She knew perfectly well that Yue Yang and Li Biao, two veteran criminal investigators, were testing her to see how capable she was.

"Okay, then I'll tell you."

"However, when I speak, I have to answer any questions I may have."

Feng Nan said with a smile.

"no problem!"

Yueyang said casually.

"OK, then I'll make a fool of myself."

Having decided to assist in solving the case and secure the position of consultant for the Major Crimes Unit, Feng Nan was naturally not unprepared. He immediately stopped beating around the bush and asked directly, "My first question is, with so many bodies and so many deaths, they couldn't all have died at the same time, could they? Why isn't there a time of death on the autopsy report?"

"Don't tell me the forensic doctor forgot to write it down. I don't believe a forensic doctor who performs autopsies for the Major Crimes Unit would make such a basic mistake."

Feng Nan smiled as she looked at Yue Yang and Li Biao.

Feng Nan knew without even guessing that these two must have been up to test him.

"I knew she'd find out, didn't I?"

"Your attempt to probe is too simplistic!"

As soon as Feng Nan finished speaking, Yue Yang pointed at Li Biao and began to mock him mercilessly.

Li Biao glared angrily at Yue Yang, then gave Feng Nan an awkward smile.

It was somewhat embarrassing to be exposed like this. Originally, Li Biao wanted to pin the blame on Yue Yang, but Yue Yang beat him to it.

"Gentlemen, please speak."

"You asked me to assist in the case, so even if we don't have the exact time of death for each body, we should at least have a general time span, right?" Feng Nan said, feigning helplessness.

In fact, Feng Nan had already determined the time of death for each victim in the future chat group, and even identified the identities of several victims who were murdered in different years.

But now that he's discovered that Yue Yang and the other guy have secretly dug a hole for him, Feng Nan can't just turn a blind eye and then be looked down upon for no reason, can he?

So, we need to clear this pit first!

"The first three victims were all murdered ten years ago. The first victim was murdered at the beginning of the year, the second victim was murdered around June or July, and the third victim was murdered at the end of the year."

"However, the time of the fourth victim's murder was almost a year apart from the time of the third victim's murder."

"After the fourth victim, the frequency returned to three per year, until the tenth victim, then there was another gap. Two years later, the body of the eleventh victim was found. Three more people died that year. From eleven to thirteen, and then until this year, the third year, no new victims have appeared."

"It is currently impossible to determine whether the murderer has stopped or abandoned this location and used another place as a new disposal site."

Li Biao rattled off the time report in one breath, including the time of death he had omitted, and the patterns they had painstakingly pieced together after staying up all night.

After listening to Li Biao's story, Feng Nan couldn't help but give Li Biao a thumbs up in her heart.

Those who are professionals are indeed professionals; their modus operandi is exactly the same as what will be revealed later.

"No, I suspect the killer didn't give up using this body disposal site, but rather that he was arrested for another crime and was unable to continue committing crimes and disposing of bodies."

Feng Nan shared her speculations, which she had pieced together from her observations of the future.

"Ok?"

Yueyang and Li Biao were both stunned.

The two exchanged a glance, and both saw surprise in each other's eyes.

The two of them also wondered what the killer did each time he paused from committing the crime.

From illness and the possibility of a car accident to going out to work, Yueyang and his companion considered every possible scenario, but they never imagined that the murderer might have been arrested for a crime.

Yueyang laughed and said, "This is interesting!"

"You know what, what you said is actually true. The first time he was sentenced to one year, the second time to two years, and this third time to more than three years."

Feng Nan smiled slightly. Isn't that interesting? This is a viewpoint that Li Biao put forward four years later. How could it not be valid?

"So this can be a direction for investigation. First, screen out the people who were arrested and sentenced during each period when the murderer disappeared. Then, from these people, find those who have been imprisoned twice or three times, and further narrow down the scope of suspects."

"I think there probably won't be too many people who meet the criteria in the end, right?"

Feng Nan revealed a profound and inscrutable expression.

Four years later, Li Biao did indeed do just that and identified several suspects. However, these individuals all had perfect alibis when Nango was killed, which is why it was impossible to pinpoint the suspect's identity.

However, when Feng Nan was reviewing the investigation record, she discovered that Li Biao had overlooked one person during the investigation, and this person happened to be one of the suspects that Feng Nan had identified.

Feng Nan became increasingly suspicious of this person, who happened to be a convict with four prior convictions for labor camp incarceration.

Therefore, Feng Nan decided to guide Yue Yang and the others to investigate this person first.

"Feng Nan, you're really something!"

Yueyang couldn't help but offer a compliment.

"Old Li, take Feng Nan to the scene and see if she can make any new discoveries. I'll immediately start screening all the people in the city who are currently serving sentences or have just been released to see if there are any people who meet this condition."

Yueyang left a message, turned around, grabbed his car keys, and ran out of the Major Crimes Unit office.
