Reborn in 1995, Criminal Investigation Records

"Zhao Jun, female, 28 years old, unmarried, a local of Ning'an, with a junior high school education, has been dealt with for theft, robbery, fraud, etc., and just finished serving her sentence in late June of this year from the neighboring Pingqing City Prison..."

This makes sense. Although he was from Ning'an, he was dealt with by the neighboring Pingqing City, so his identity information could not be found in Ning'an's system.

"Now that we've identified the first victim, we need to find out where he went after his release from prison, when he returned to Ning'an, who he contacted, and so on. We need to investigate every detail!" Liu Chengyu pumped his fist to encourage everyone.

The next urgent task is to quickly find out the identity of the second victim. Only in this way can we determine the killer's motives or patterns based on the connection between the two victims, which will facilitate the investigation.

Then, with the help of the local police, they tried to locate the torso.

Finally, the characteristics of the killer summarized by the 7.6 task force after discussion:

Male, height between 170-175 cm, good at disguise, owns a bicycle, lives about 35 minutes by bicycle from Xiangjiang Restaurant and about 1-3 kilometers from Xiangjiang Hotel.

The home has a large refrigerator or cold storage.

As for the last point, it was Wang Chao who suggested adding it, because he felt that the fact that the victim's leg could be frozen completely without being broken or bent indicated that there was a lot of space.

This point was almost universally agreed upon by the task force, so it was added, which further narrowed the scope.

Xiangjiang Subdistrict has the smallest area among the five subdistricts, but its population density is exceptionally high.

At that time, both the Xiangjiang Hotel and the restaurant were located in bustling areas.

Therefore, there were more people conducting investigations and visits, but fortunately the case is slowly moving forward.

......

Regarding the identity of the second victim, although the victim had a head and limbs, there has been little progress. No matching information has been found, whether it's a missing person report or a database.

"Just like I told you before, this body has also been processed, just not as roughly as last time!" In the forensic room, on the autopsy table, lay the reassembled body of the deceased.

The cut-off section, like a red ribbon, possessed an eerie beauty.

"Including the head, everything has been washed with bleach, and look here!" Wang Zhenhai shone a UV lamp on the area around the thigh, revealing an unnatural yellowish-white color at the base.

Zhou Yang thought of a possibility and pushed the ultraviolet lamp with his hand, shining it on another one, which also showed the same color.

"The killer most likely washed their genitals a long time ago!" Then he stared wide-eyed at Wang Zhenhai: "Very likely, they had sexual intercourse! There might even be semen residue!"

Wang Zhenhai nodded and gave Zhou Yang a thumbs up. He had also thought about it for a long time before coming up with this guess, but he didn't expect that this young man could immediately figure out the key point just by looking at it.

But then he poured cold water on the idea: "However, no semen was extracted from it. Logically, that stuff isn't just surface dirt; it seeps into skin folds. The bleach might only have damaged the surface DNA, while deeper DNA residue could still be extracted!"

Zhou Yang nodded: "It's very difficult for an ordinary person to evenly and thoroughly soak or brush every spot of semen, let alone a murderer who has killed someone and is in a state of tension. He's not tense, but rather very excited, but that's still not easy for him. So the most likely explanation is that it wasn't there to begin with!"

Wang Zhenhai lit a cigarette outside the door. Compared to Zhou Yang, he felt that the disciples he had taken on were not apprentices at all, but simply talking pigs.

Not only do you have to explain those things, but you also have to explain why, and in the end people will just say, "Really? That's too difficult!"

"Teacher Wang, how did this happen?" Zhou Yang asked, pointing to an unusual spot on the other person's thigh.

Wang Zhenhai exhaled a puff of smoke and was about to reply.

"It's a tattoo that was removed, right?" Zhou Yang muttered to himself, earning a glare from Wang Zhenhai. "Also, there's a considerable smoking history, and a fixed denture in the lower right molar area. These should all be useful to you!"

"Can you determine the cause of death?" Zhou Yang nodded. He knew that Teacher Wang was giving him a direction for the investigation. After all, the body had only been brought back for a short time, and the initial report from the autopsy wouldn't be available so soon.

"You little brat!" Wang Zhenhai stubbed out his cigarette. "Because the cut surface on the neck is relatively high, there is no soft tissue in the neck to examine, but there are fractures of the hyoid bone and thyroid cartilage, and pinpoint hemorrhages in the eyelids and bulbar conjunctiva. These are typical characteristics of strangulation or suffocation. It can be basically determined that the death was caused by asphyxiation."

After leaving his words of thanks, Zhou Yang immediately jogged back to the First Brigade office.

"Since no one is coming to identify the body, let's offer a reward. That will encourage more people to come forward!" Dai Yan pushed up his glasses and suggested.

He couldn't help but be anxious. Now was the golden opportunity to solve the case. He had thought that since the head hadn't been damaged and the face was intact, things would be easier. But so far, he hadn't found any clues about the victim.

"Let me tell you the clues I just got from the forensic lab... bleach... cleaned... tattoo... dentures... suffocation..." As Zhou Yang relayed the information, the seriousness on everyone's faces eased slightly.

"Based on what Zhou Yang just said, we'll go to all the hospitals and dental clinics in Ning'an to find the information the other party registered. Then we'll go to hair salons, video arcades, nightclubs, and billiard halls to look for clues about this tattoo. Finally, we'll find the shop that sells bleach and see if the owner remembers it..."

As soon as Liu Chengyu finished speaking, everyone in the office immediately sprang into action, quickly and in an orderly manner.

Zhou Yang had seen the autopsy report of the first victim. At that time, the methods used by the murderer to dispose of the body, create models, and destroy the characteristics of the body were still very crude.

"Too fast!" Zhou Yang murmured.

"What's too fast?" Fang Duo turned her head and looked at Zhou Yang in confusion as she drove.

"You've progressed too fast!" Zhou Yang said in a low voice.

It's important to understand that most criminals, regardless of their type, need a necessary transition and trial-and-error period between their initial clumsy attempts at the crime scene and their near-perfect presentation of the crime. But this killer skipped that process; it was as if he achieved "maturity" in one step.

In less than a day, he had already learned to use bleach to clean corpses and resin glue to piece them back together. It was hard to imagine what kind of monster the other party would evolve into if there were three or four more cases.

"Perhaps, this person is a born criminal?" Fang Duo sighed.

Born criminal? Zhou Yang's eyes narrowed. These things are unlikely to be learned without a teacher. Most likely, the other party has someone by their side, or has information that can instantly improve these counter-surveillance techniques!

"Squeak—creak!!"

The rubber rubbed against the asphalt, making a screeching sound, and the car suddenly stopped.

Fang Duo, whom Zhou Yang once considered a mature and composed woman in the team, was just as capable as Wang Chao when it came to driving. If she hadn't been habitually holding onto the overhead handrail, she would most likely have been hit by the windshield during that sudden stop.
