Eyes that are the same as those of evil

Chapter 135 Fourteen Years of Pursuit 1
The test results surprised everyone; the remaining bloodstains pointed to the family members of someone within the police department.

Wu Yang was also shocked.

“How is that possible? I’ve never seen a folding knife like that in my house. And my dad has never had a history of cutting himself and losing a lot of blood.”

Zheng Yan has never met Wu Yang's father, so she cannot make a judgment.

After pondering for a while, he looked at the knife again.

"If the shop that sold this knife only made modifications by spraying red paint, and the rust and wear on the blade are inherent to the knife, then it can be determined that this knife is from many years ago."

Tan Jia followed his line of thought and analyzed further: "The knife may belong to the shop owner, but it is more likely that he acquired it. He bought it for the price of scrap metal, and only needs to spray some fake blood on it to sell it to people who like immersive murder mystery games. The price can be several times higher. If there are many buyers, he can only acquire it. It is best to acquire some scrap metal that originally has the aura of a murder weapon. In that case, it is not surprising that a real murder weapon appeared."

Xiao Chen: "So someone sold the knife that had stabbed Wu Yang's father to the shop owner, and then the shop owner sprayed some paint on it and made up a fake murder story to sell to Qi Ziqin. Qi Yao then used this knife to stab Tang Tianyu."

“My dad was never stabbed.” Wu Yang was speechless.

Xiao Chen: "What if it happened, but you just didn't know it?"

"That's possible, but my mom would know eventually. She tells me everything, but she's never mentioned anything like this."

The DNA testing personnel then said, "I retested, and the result is only a high match. Since you still think it can't be your father, it means that these bloodstains most likely come from your father's close relatives."

Wu Yang was stunned and began to recall which of her relatives was most likely to be involved in the criminal case.

The testing personnel added, "We've been building the Y-STR database over the past two years. Based on the Y chromosome of paternal relatives, we can confirm the family a sample belongs to. The person who left bloodstains on the knife should be a man in your family."

The criminal investigation team is no stranger to this technology. During the previous period of re-investigating cold cases, several cases from ten or twenty years ago were solved thanks to Y-STR technology.

In particular, in cases of sexual assault, this technology can even identify the number of people involved in gang rape.

Even if the murderer's DNA is not in the system, as long as a male relative related to the murderer has had his blood sample taken and left a DNA sample, the family can be identified. By screening the family members, the real murderer can be found quickly.

Tan Jia also knew that in recent years, countries around the world have been building their own national Y databases, which will make it faster to investigate suspects in criminal cases in the future.

But this happened too fast; even the suspected victim's family members couldn't remember.

They looked at Wu Yang again, but Wu Yang suddenly looked at Zheng Yan.

She thought of a possibility.

"...That was my grandfather. Fourteen years ago, he was stabbed twice by a robber who had come to the area to commit crimes. He died before the ambulance arrived."

"The murderer stabbed my grandfather while on the run and then ran away with the murder weapon, leaving no clues to follow. When I first became a police officer, I wanted to find out the truth about this case, but the robber never committed another crime, and I had no leads, so I had to give up."

The more she spoke, the brighter her eyes became.

"If this knife is the murder weapon that stabbed my grandfather, then I can find the murderer."

Tan Jia, Tan Ming, and Xiao Chen were taken aback by the unfolding story and stared at her with wide eyes.

But they quickly realized what was happening and helped analyze the situation.

"Investigate the shop owner and ask him to recall who sold him the knife. If you're lucky, that seller might be the murderer you're looking for."

"We can also check the origin of this knife, what brand it is, where it was manufactured, if we can find that out."

In the end, it all boils down to one sentiment.

"This is amazing. After investigating for so many years, we actually found a clue in a completely unrelated case fourteen years later."

Wu Yang also felt as if a fire was burning in her chest, and she couldn't sit still. She immediately wanted to check out that store.

“Captain Zheng, I won’t go to lunch with you guys. I want to stay in the office…” “Why bother with lunch? This is another case, and we all have to stay and investigate,” Zheng Yan patted her shoulder. “Don’t panic. If we work together, we can find out the truth faster.”

The dinner was canceled, and they returned to the office to investigate the murder mystery prop shop, the origin of the folding knife, and the case files of a robbery from fourteen years ago, assigning tasks to each person.

Tan Jia is the only one who doesn't have to stay and work overtime.

Her role as a dream specialist was useless in cases where the clues were obvious and only needed to be verified; she could go home and sleep.

The sky outside was getting dark, and she walked slowly, still thinking about Grandpa Wu Yang.

It sounds like the robber killed an innocent elderly person who was passing by, and then disappeared for more than a decade after fleeing.

Why did the murderer kill Grandpa Wu in the first place? She couldn't see the case file and didn't know the inside story.

Fourteen years have passed, is the murderer still alive? So many years have passed without a trace, is he dead or has he really been hiding so well?

Lost in thought, I heard the sound of a car door closing in front of me, "bang!"

She looked up and saw Lin Zhiyue standing in the dim light.

When you look at someone in the dim light, it's as if their eyes have an automatic filter applied, creating a sense of atmosphere. It blurs many details in sharp lines and complex gazes, leaving only a fleetingly beautiful impression.

"Why are you still here?" she asked.

Lin Zhiyue stood there at a distance, staring at her with a somewhat resentful look in his eyes.

“I’ve always been here.”

She smiled and said, "I didn't ask you to wait here for me."

His eyes held not only resentment but also a hint of frustration, yet he still asked, "Are you going home?"

"To be clear, we are all going back to our own homes. People who don't know the situation might think we are going back to your home."

These words made him even more unhappy, and he pursed his lips and stopped talking.

Tan Jia walked to his side, and his gaze followed her as she opened and closed her lips to say the next sentence.

"Have you eaten? I'll treat you to Japanese food. Captain Zheng and the others are busy with something, so it'll just be the two of us who can go out and enjoy some good food."

Lin Zhiyue's lips relaxed and turned up slightly before he opened the car door.

"Okay." He said.

……

After enjoying a delicious meal, Tan Jia went to the police station again the next morning.

Several people were sprawled out in the office, but Wu Yang was still bent over and standing by the computer, his brows furrowed, talking quietly with the technical team.

"Did you find anything useful?" she asked in a low voice, handing over a bag of breakfast.

When Wu Yang saw her, he closed his tired eyes and said in a hoarse voice, "No. The shop owner doesn't remember who sold him that knife, and the factory that produced the knife went bankrupt ten years ago, so he doesn't know who bought it or when."

"What is the technical team investigating?"

"Let's check the purchase records and chat logs of the owner of that murder mystery prop shop to see if we can find information about the knife."
