At this moment, Wang Yi was like an obedient kindergarten child, answering whatever Xu Mo asked.
Captain Li couldn’t understand why Wang Yi had changed so quickly, going from stubbornly refusing to talk to now answering every question, as if he had become a completely different person.
He didn’t understand it, but he was utterly shocked.
Xu Mo’s interrogation skills were indeed unique!
“You killed your brother? Why did you kill him?” Xu Mo asked, puzzled.
“After killing that father and daughter back then, my brother and I went home to pack up and run away, to lay low for a while. But for some reason, he got it into his head to turn himself in,” Wang Yi said, still angry even after all these years, recalling the incident.
He couldn’t understand why his brother wanted to turn himself in.
“I tried to talk him out of it for a long time, but he wouldn’t listen. He insisted on turning himself in. Fine, if he wanted to do that, I wouldn’t stop him. But then he wanted to rat me out too!”
“We had a disagreement, and he tried to tie me up to take me to the police. We fought, and I accidentally killed him. I buried him under the willow tree in our backyard at our old home.”
After hearing Wang Yi’s story, Captain Li finally showed a look of realization.
“So that’s what happened…” he muttered to himself.
No wonder Wang Bo had never been caught by the police for seven years. No wonder, in this age of advanced technology, surveillance had never captured Wang Bo—because he was already dead! After the Wang brothers committed the crime, Wang Bo had been accidentally killed by his younger brother, Wang Yi.
The Wang brothers hadn’t gone their separate ways after the crime, and Wang Bo hadn’t mysteriously disappeared. He had been killed by Wang Yi, which was why the police couldn’t find him. That was also why Wang Yi claimed he was just an accomplice and that his brother was the mastermind. Since his brother was already dead, this lie allowed him to escape legal punishment forever.
As long as the mastermind remained at large, the case couldn’t be closed. But the “mastermind” Wang Bo had been dead for seven years. The police would have had no chance of catching him!
It was all thanks to Xu Mo. If he hadn’t gotten Wang Yi to reveal Wang Bo’s whereabouts, who knows how long it would have taken to close the case?
Captain Li couldn’t help but glance at Xu Mo, the hero of the day.
He was curious—what method had Xu Mo used to make Wang Yi talk? Could it really have been just a glare?
After getting the answers they needed in the prison, the team immediately left, heading to Wang Yi’s hometown to check if there was indeed a body buried under the large willow tree in his backyard.
On the way, Captain Li kept glancing at Xu Mo.
Finally, he couldn’t hold back any longer and asked, “Captain Xu, what exactly did you do to make Wang Yi confess?”
Of course, it was the truth serum… Xu Mo smiled. “Captain Li, you saw it yourself. I just asked, and he answered. Maybe Wang Yi was tired of prison life, or maybe these years behind bars changed him. I just happened to catch him at the right moment, so he talked.”
That’s what Xu Mo said, but Captain Li didn’t believe a word of it.
Wang Yi, tired of prison life? Changed after a few years in prison? Impossible!
When they had first met Wang Yi earlier that day, the guy’s lips had been sealed tight. He didn’t seem like someone who had turned over a new leaf.
It must have been as Han Fei said—Xu Mo had some unique interrogation technique. Thinking this, Captain Li glanced at Han Fei sitting in the back.
Han Fei noticed Captain Li’s look and shrugged, thinking, *Why are you looking at me? I don’t know how Xu Mo did it either. If you’re curious, I’m even more curious.*
Though Han Fei was also curious about Xu Mo’s methods, he was used to such situations, having experienced them more than once before.
The rest of the journey passed in silence.
Dazhuang Village.
This was the registered hometown of the Wang brothers, Wang Yi and Wang Bo.
In the backyard of the Wang family home, the team indeed found a thriving willow tree.
Tools were readily available in the yard, and the officers grabbed shovels and started digging around the tree’s roots without hesitation.
After half an hour of digging, there was a *clang*—the shovel had hit something.
“There’s something down here!” the officer digging called out.
“Keep digging!” Captain Li’s eyes lit up, but seeing the officer sweating profusely, he took the shovel. “You take a break. I’ll take over.”
A few more digs, and a skull came into view.
Continuing, Captain Li unearthed a complete skeleton.
The body had completely decomposed into bones, suggesting it had been buried for a long time—likely around seven years.
When Wang Yi had been arrested, officers had searched his hometown but hadn’t found the body under the willow tree. The reason was that Wang Yi had been captured two years after the crime, and by then, the soil around the tree showed no signs of being disturbed.
Excited as he was, Captain Li thought of a problem.
“Even though we’ve found a body, how do we confirm its identity? Could Wang Yi be lying? What if this isn’t his brother but someone else he killed?”
“That’s simple,” Xu Mo said. “We can test the DNA. Bones and teeth can preserve DNA for a long time. In theory, if not exposed, DNA in bones can last for hundreds or even thousands of years.”
…
The officers took the skeleton back to the station, collected Wang Yi’s DNA from the prison, and also brought in the brothers’ parents.
Simply extracting the DNA from the body and Wang Yi wouldn’t be enough to confirm they were brothers.
To determine a sibling relationship through DNA testing, the parents’ DNA was needed as additional evidence.
Only a parent-child DNA test could provide a 100% confirmation without needing further evidence.
After the tests, the officers got their results.
The body buried under the willow tree was indeed Wang Yi’s brother. Their parents also confirmed they had only these two sons and no other children.
The identity of the body was confirmed—it was Wang Bo!
Combined with Wang Yi’s earlier confession in prison, this seven-year-old case could finally be closed.
