After bringing Yu Xiaofei back to the police station, Han Fei and Xu Mo immediately began interrogating him.
Interrogating this guy was quite challenging, and even Xu Mo found himself feeling a bit stumped.
Earlier that morning, Xu Mo had easily gotten Qiu Yuanhang to confess, primarily because Qiu felt guilty about the murder. This was evident from how he had donated most of the money he had earned afterward to charity.
Moreover, Qiu Yuanhang was essentially an ordinary person, fundamentally different from Yu Xiaofei.
Under the high-pressure environment of the interrogation room, ordinary people's mental states often crumbled easily. Combined with Xu Mo's "deductive reasoning" of the past events in front of Qiu Yuanhang, the already nervous Qiu couldn't think straight and assumed the police had solid evidence against him, so he confessed.
But Yu Xiaofei was different. He had a criminal record, and this wasn't his first time at the police station. In fact, after his parents left, he became a regular at the local police station back in his hometown.
He wasn't a frequent visitor to Ram City police station; it was his hometown's station.
He had even served time in prison!
He was a tough nut to crack, thoroughly familiar with the police's routines. Added to that, with no parents to discipline him from a young age, Yu Xiaofei was adept at lying, spouting falsehoods effortlessly.
Showing weakness in the interrogation room? Not a chance!
"I’ve truly reformed! Why don’t you believe me? Just because I have a criminal record, you can unjustly accuse me of being a murderer? That’s discrimination! I’m going to expose you!" Not only did Yu Xiaofei refuse to confess, but he also slapped Xu Mo and Han Fei with the accusation of discriminating against former inmates.
Close to the end of the workday, Xu Mo didn’t have time to waste... glancing at the clock, he decided to wrap things up quickly. He’d give Yu Xiaofei a dose of truth serum and not waste any more words.
After more than an hour of interrogation, Yu Xiaofei stubbornly refused to admit anything, denying his involvement in the five-year-old case.
There were only two ways to convict him: first, by finding solid evidence, and second, by getting him to confess.
Evidence was undoubtedly absent since five years had passed. Moreover, if any evidence existed to prove Yu Xiaofei was the killer, the police would have found it back then, and the case wouldn’t have dragged on this long.
Xu Mo initially avoided using the truth serum because he only had one dose left and wanted to conserve it. But now it seemed this last dose couldn’t be saved; it had to be used to avoid delaying his timely departure from work.
Han Fei was completely out of ideas. This guy was too hard to interrogate, and now he could only hope Xu Mo would deliver.
After questioning for so long, Yu Xiaofei either denied being the killer or simply remained silent.
Likely, this was a tactic he had learned from fellow inmates while in prison. Yu Xiaofei knew that, without concrete evidence, as long as he stuck to his story, he’d be released when time was up.
Xu Mo’s technique for administering the truth serum had become increasingly skillful, allowing him to inject it into the suspect’s body without being detected by the interrogation room’s cameras or Han Fei’s watchful eyes.
Once the truth serum took effect, Yu Xiaofei became much more cooperative, answering every question without hesitation.
Using this, Xu Mo easily got Yu Xiaofei to confess to the crime in front of Han Fei.
"Why did I kill him?"
"Because he swindled my money... About seven years ago, I had just been released from prison and couldn’t find a job, so I started setting up a small stall. After two years of selling, I saved up close to 500,000 yuan."
"Originally, I planned to use that money to rent a shop and open a small store to make a living. But then I ran into that con artist. He told me to give him the money, and he’d invest it for me, making money grow money, and within a year, I’d earn a million. I was naive and believed him, handing over all the money, keeping only enough for a few months' rent."
"After some time, I realized he wasn’t investing my money but had spent it on his lavish lifestyle. That was my entire savings! The result of two years of hard work, getting up early and staying out late, saving every penny I could."
"When I confronted him and demanded my money back, he refused and even had a few guys beat me up. He told me the money was gone, spent, and warned me not to bother him again, or he’d have me beaten every time he saw me. I couldn’t let him get away with squandering the fruit of two years of my life, so I waited for him on the small path he took home every day and killed him."
Xu Mo had already learned the reason behind Yu Xiaofei’s murder from the fortune teller's clue. However, just knowing it wasn’t enough; Yu Xiaofei needed to confess in the interrogation room for the conviction to stick.
"You killed him just because he scammed your money?" Han Fei was stunned. "Couldn’t you have reported it to the police instead of ending up hurting yourself?"
He never expected the motive for Yu Xiaofei’s murder to be so simple.
Originally a victim, Yu Xiaofei had now turned himself into the criminal, a huge loss.
"I gave him all the money in cash, not through a transfer, so I have no evidence he swindled me. Plus, with my criminal record, even if I’d gone to the police, would you have believed me?"
Han Fei nodded without hesitation.
"Of course, we would. We believe anyone who comes to report a crime, regardless of their background. That’s a fundamental part of being a police officer."
"Here’s your confession record. Take a look, and if everything’s accurate, just sign here."
Yu Xiaofei casually flipped through the record and then took the pen to sign his name.
With that, the case was concluded.
The only two unsolved cases in the police station had both been resolved through Xu Mo’s efforts.
"You successfully apprehended the fugitive. Reward received: Truth Serum × 10!"
A notification sounded in Xu Mo’s mind as his supply of truth serum ran out, and the system kindly replenished it.
After the interrogation, as soon as Han Fei exited the room, he heard noise outside.
To find out what was going on, Han Fei quickly walked over.
He saw a slightly thin man recounting his ordeal to a police officer.
"Officers, you have to help me seek justice and arrest her!"
"What’s the matter?" Han Fei asked.
"Deputy Chief Han, this is Mr. Li. He claims he was violently assaulted by a woman."
Han Fei: "?"
A man being... assaulted by a woman? How is that possible?
Was the complainant drunk or high? Han Fei was considering whether to take the man for a urine test.
"Ahem... Chief Han, didn’t you just say something in the interrogation room with Yu Xiaofei?" Xu Mo, standing nearby, saw through Han Fei’s thoughts and coughed to remind him.
"What did I say?" Han Fei momentarily couldn’t recall what Xu Mo was referring to.
Xu Mo: "???"
Who just said they would believe any informant’s account, regardless of their background? And that it was a fundamental part of being a police officer?
Chief Han, where’s your professional integrity now?
