The rain outside the window was still pouring down, and several police officers had already driven to various hospitals under the surveillance of the cameras.

Under the gloomy sky and pouring rain, the determined back view of the police officers satisfied the photographer. While taking pictures, he said to Huang Qiangming, who was waiting in the lobby, "Give this set of photos a nice name, and the publicity effect will be maximized."

Huang Qiangming twisted his neck and looked at the photographer's profile, slowly saying, "Maybe it would be better to follow them and take more photos."

"Huh? Well... actually, the photos we took are already enough..." The photographer hurriedly smiled, listening to the sound of rain outside the window.

Theft is never good, try looking at [ pawread dot com ].

"Go ahead, just like the team in Qinghe City, take more photos and come back for better publicity." Huang Qiangming handed him a raincoat and watched him walk out of the door and into the rain.

The news from the front line kept coming back, bringing both joy and worry.

The good news was that the laser tattoo removal records of all hospitals had been documented, and the location of the tattoo could be determined with careful searching. The bad news was that they had not found any records that matched the deceased in any hospital so far.

Liu Wenkai, the captain of the second team, was searching for information in the office of the First People's Hospital of Qinghe City.

Qinghe City was the administrative center of the Qinghe area, and people from Ningtai County would come here first if they had any major illnesses.

The distance between the two places was not far, only a few dozen kilometers, and those with cars could arrive quickly, while there were also many public transportation routes. Qinghe City was also crossed by the Tai River and was an upstream city of the river.

Of course, there were also many people from Ningtai County who went to Changyang City for medical treatment, but there were too many hospitals in Changyang City, and it was not easy to search through them. Liu Wenkai and Huang Qiangming agreed that they should first search the local hospitals in Qinghe City and Ningtai County. If they still could not find anything, they could then try to find a solution in Changyang City or even further upstream.

Liu Wenkai sat in front of the computer, watching the doctor trace the medical history all the way back to two years ago, but still had not found anything, making him anxious.

"Can't you search for keywords like 'leg' or 'Fengshi acupoint' and find all the previous cases?" Liu Wenkai suggested.

The doctor glanced at him and said, "Why don't you make a software like that for us?"

"Your software is too outdated." Liu Wenkai made a sarcastic comment and added, "Don't miss anything, take your time."

"Aren't you in a hurry?"

"Of course, how could I not be in a hurry? What year have you searched up to?"

"We are almost at the beginning of the year before last. Many people get tattoos removed around the time of the Chinese New Year."Liu Wenkai's expression became more serious. The forensic determined that the deceased was between 23-25 years old. If we deduct three years, it would be between 20-22 years old. The probability of getting a tattoo at a younger age is lower. As a veteran detective, he knows what type of tattoos minors usually get. A single tattoo on the thigh of a male, only the size of a fist, does not look like a tattoo style for minors.

"Maybe it wasn't done in our hospital. There are many places that offer tattoo removal now, even beauty salons..." The doctor searched while speaking.

Liu Wenkai said, "The forensic said it was washed quite clean."

"Oh, then it might have been done in a hospital. But it's not necessarily our hospital."

"We are all searching in our respective hospitals. Can you please keep looking? If we can't find it, we'll discuss it again." Liu Wenkai spoke politely but with a hint of frustration. He knew that it was possible that they might not find anything. In fact, they couldn't even be sure if the deceased died in Ningtai County.

But for them, they had no choice but to investigate one hospital at a time.

The doctor became tired from searching and muttered, "Actually, some beauty salons can also do tattoo removal now. The cleanliness of the removal depends largely on the pigments used during the tattooing process. Black and dark blue pigments are generally easier to remove, while mixed pigments are more difficult. It also depends on the individual's physical condition. I've seen someone who only needed one removal, while others needed ten or more and still couldn't remove it. Some even ended up with scars after the tattoo was removed..."

As the doctor spoke, his pace slowed down and he stopped moving.

Liu Wenkai stood up sensitively and walked over to see what was going on.

"Take a look and see if it's similar." The doctor opened a file and showed Liu Wenkai the photo.

Liu Wenkai didn't tell him that they only had half of the body. He remained silent and said, "Let's look at the tattoo first."

The doctor then found another photo.

Sure enough, there was a string of English letters on the right side of the thigh, written in cursive and tangled together in black.

Judging from the location alone, it should belong to one person.

The doctor looked closely and read aloud, "I-believe. I believe in what?"

"What do you believe in?" Liu Wenkai asked.

"Who knows what he believed in. If we're talking about the tattoo, it was done two years ago. It was probably done at a random tattoo shop on the street, and the quality is not good." The doctor flipped through the file and printed it out for Liu Wenkai. "This should be a low-quality tattoo done at a random tattoo shop."

He was a professional when it came to tattoos.

Liu Wenkai nodded slowly and took out his phone. "I'll make a call. Thank you."

As he spoke, he dialed his phone.

"How did it go?" Huang Qiangming answered the phone quickly."Found him. The deceased's name is Zhou Lei, 24 years old. He has an ID number, but I haven't checked it yet. I'll send it to you later..." Liu Wenkai was quite excited.

For a case like this, identifying the victim's identity can be considered a huge milestone victory.

For most similar cases, if you follow the victim's network of relationships, there is a high probability of solving the case.

Well-designed cases are ultimately rare. Even if the perpetrator designs a sophisticated method of attack, the number of killers who can execute it flawlessly is extremely small. Even fewer of them have no accidents in the process.

In Liu Wenkai's impression, it was the old hooligans and rascals who often went in and out of the police station that could barely manage their emotions and expressions when facing the police.

Most killers do not know how to deal with the police.

This is why the police often have to go door-to-door for investigation and questioning.

Calling or inviting the other party over makes it easier for them to prepare psychologically and increases the difficulty of interrogation or questioning.

"Okay, I'm leaving now. Be sure to keep it confidential and don't tell anyone else about this. If someone asks, just tell me, okay?" Liu Wenkai reminded and hurriedly left.

On the other hand, the entire criminal investigation team became excited, and several police officers in Qinghe even gathered together, took the initiative to work overtime, assigned tasks to themselves, and rushed around actively.
