Chapter 484: Case Closed

At this moment, Wang Yi was like an obedient kindergarten child; whatever Xu Mo asked, he answered.

Li Dui didn't understand why Wang Yi changed so quickly, from originally refusing to speak about life or death to now answering whatever was asked, as if he had become a different person.

He didn't understand, but he was greatly shocked.

Xu Mo's interrogation technique truly was unique!

"You killed your brother? Why did you kill your brother?" Xu Mo asked, somewhat puzzled, and continued.

"After we killed that father and daughter back then, my brother and I went home, prepared to pack our things and run away, to lay low for a while. I don't know what twisted his mind, but he actually wanted to turn himself in." Saying this, Wang Yi felt a bit indignant; years later, recalling those events, he couldn't help but feel angry again.

He didn't understand why his brother wanted to turn himself in.

"I tried to persuade him for a long time, but he wouldn't listen, insisting on turning himself in. It's one thing that he wanted to turn himself in; I wouldn't stop him. But he actually wanted to implicate me as well!"

"Our opinions clashed, and he wanted to bind me and turn himself in. We fought, and I slipped up and killed him, burying him under the willow tree in the backyard of our old home."

After hearing Wang Yi's words, Li Dui finally showed a look of sudden realization.

"So that's how it is..." he murmured to himself.

No wonder Wang Bo hadn't been captured by the Police for a full seven years; no wonder that even with today's advanced technology, surveillance never caught Wang Bo, because he was already dead! After the Wang brothers committed the crime, Wang Bo was accidentally killed by his own brother Wang Yi.

After the Wang brothers' crime, they didn't go separate ways; Wang Bo didn't mysteriously disappear—he was killed by Wang Yi, which is why the Police couldn't find Wang Bo. That's why Wang Yi claimed he was an accomplice and his brother the principal offender; since his brother was already dead, this claim allowed him to forever evade legal punishment.

As long as the principal offender remains uncaught, the case cannot be adjudicated and closed; yet the "principal offender" Wang Bo that Wang Yi mentioned had been dead for seven years, so the Police being able to catch him is impossible!

Thanks to Xu Mo, if he hadn't extracted Wang Bo's whereabouts from Wang Yi, no one would know when this case could be closed.

He guessed that they would probably have to wait until Wang Yi eventually grew tired of prison life before he would reveal the truth.

Thinking this, Li Dui couldn't help but look at the Great Merit hero Xu Mo.

He was very curious about what method Xu Mo used to make Wang Yi confess—was it really just because he glared at Wang Yi?

The group obtained the result they wanted in the prison, then immediately left the prison, preparing to go to Wang Yi's hometown to see whether under the big willow tree in his family's backyard lay Wang Bo's corpse.

On the road, Li Dui kept glancing at Xu Mo from time to time.

Finally, he could no longer hold back and asked for advice.

"Team Leader Xu, what method did you just use to get Wang Yi to reveal the truth?"

Of course it was a truth serum... Xu Mo smiled: "Li Dui, didn't you see? I asked him and he answered. Maybe Wang Yi had had enough of prison life, or perhaps those years he spent in prison reformed his heart; I just happened to catch him at the right moment, so when I asked, he spoke."

He said that, but Li Dui didn't believe it at all.

Wang Yi had had enough of prison life? After a few years in prison, he reformed? How could that be possible!

To know, when they first saw Wang Yi today, the kid's mouth was still tightly shut; nowhere did he look reformed.

It must be, as Han Fei said, that Xu Mo has some unique interrogation technique... With this thought, Li Dui glanced at Han Fei sitting behind him.

Han Fei noticed Li Dui's gaze, shrugged, and thought, "Why am I being looked at? I don't know how Xu Mo did it either; you're curious, I'm even more curious."

Although Han Fei was also curious about Xu Mo's interrogation methods, he was, after all, a veteran; he had experienced such situations more than once and was already accustomed to them.

No words were spoken all the way.

Da Zhuang Village.

This is the household registration place of the Wang Yi and Wang Bo brothers.

The group indeed saw a thriving big willow tree in the Wang family's backyard.

Tools were already in the yard; the officers, brandishing iron shovels, without a word began digging at the roots of the big willow tree.

They dug for a full half hour, then heard a clang as the iron shovel hit something.

"There's something below!" the officer in charge of digging said, turning back.

"Keep digging!" Li Dui's eyes lit up, but seeing the officer's forehead dotted with bean-sized beads of sweat, he took the iron shovel: "You rest over there, I'll take over."

After a few more shovelfuls, a skull appeared in everyone's view.

Continuing to dig, Li Dui uncovered a complete skeleton.

The corpse had become completely skeletal, suggesting the years weren't short; calculating the burial time, it was about seven years.

When they had captured Wang Yi, the officers also visited his old home but didn't find a corpse under the willow tree. The reason was that Wang Yi was apprehended two years after the incident, and by then the soil layer under the willow tree had long lost any digging marks, so the officers didn't notice that someone had been buried there.

Excited, Li Dui thought of a question.

"Even though we actually dug up a corpse, how do we know its identity? Could Wang Yi be lying, and this corpse not be his brother's but someone else he killed?"

"That's simple," Xu Mo said. "We can test DNA; DNA in bones and teeth can be preserved for a long time. In theory, if not exposed, bone DNA can last hundreds or even tens of thousands of years."

……

The officers took the skeletal remains back to the Police Station, also extracted Wang Yi's DNA from the prison, and additionally brought the brothers' parents in.

Simply extracting the corpse's and Wang Yi's DNA cannot 100% confirm whether they are biological brothers.

To verify by DNA whether two people are brothers or siblings, parental DNA is needed as corroboration.

Only a parent‑child DNA test can determine with 100% certainty if they are biologically related, and it requires no additional evidence.

After a round of verification, the officers reached a result.

The body buried by Wang Yi under the willow tree was indeed his biological brother; the parents also stated they have only these two sons and no other offspring.

The identity of the corpse was confirmed: the deceased was Wang Bo!

With Wang Yi's earlier confession in prison, this case that had been pending for seven years could finally be concluded.
