Chapter 750: Chapter 693: Close the Case

The victim Liu Zhiwu’s mother came with her brother and nephew.

Along the way, the relatives comforted Yang Xiuli, which somewhat improved her mood. Upon meeting Liu Cheng, she even asked, "Officer, when can I take my son home?"

Liu Cheng’s attention was originally focused on his nephew Yang Wanjun. He was taken aback by Yang Xiuli’s question before responding, "I’m afraid you’ll have to wait until we close the case. Please be patient for a little while longer."

"When can the case be closed? When can the murderer be found?" Yang Xiuli pressed on.

The attitude of the victim’s family is very important to the police. Liu Cheng replied amiably, "We are currently investigating. There have been some findings, which is why we’ve called everyone in to make a statement. It’s also helpful for us to learn about the situation."

"What have you found?" Yang Xiuli was somewhat eager. To her, her son had been gone for a long time, and she wanted to know every bit of news.

Liu Cheng shook his head slightly and said, "I apologize, but the case is still under investigation, and this information is confidential."

"Even if I am the victim’s mother, I can’t know?"

Liu Cheng shook his head again and called a detective over, saying, "Let’s start by taking your statement. As soon as there is something I can share with you, I will notify you immediately."

Yang Xiuli’s sister-in-law came over and took Yang Xiuli away.

Yang Wanjun had been observing the police officers the whole time, but he had been silent throughout. He now followed closely behind his aunt until the detectives called him into a separate interrogation room.

After the group dispersed, Liu Cheng let out a sigh and said to Jiang Yuan, "Shall we go to the surveillance room together?"

"Okay," replied Jiang Yuan. He closed his eyes and recalled the gait of Yang Wanjun, who had just left, saying, "The footsteps left at the memorial site should belong to Yang Wanjun."

When faced with the man himself, Jiang Yuan was still not certain whether Yang Wanjun was the one behind the murder.

From the observation just now, Yang Wanjun appeared to be an ordinary young man around 30 years old, wearing a plaid shirt and sneakers, with somewhat weak social skills, but not completely incapable of social interaction.

The impression he gave was less like that of a photographer or photography enthusiast and more like that of a programmer or programming hobbyist.

Liu Cheng couldn’t be sure either if Yang Wanjun was the mastermind, but he was still encouraged and said, "Any breakthrough is a good thing, even if he’s not the murderer, he’s definitely an informant."

Liu Jinghui nodded slightly in affirmation of the reasoning enthusiast.

The surveillance room.

On the big screen, the interrogation room where Yang Wanjun was located was isolated, taking up a quarter of the screen, while the live footage from the other interrogation rooms was displayed on the side.

Liu Cheng’s rank wasn’t high enough to use the department’s command center, so the level of information technology instantly reverted to that of Ningtai County, which Jiang Yuan and his colleagues found quite familiar.

People like Liu Jinghui and Li Haochen stood behind Jiang Yuan, each wearing a wireless earpiece, able to adjust the sound from different interrogation rooms. Almost in unison, they all selected interrogation room 3, where Yang Wanjun was.

It was evident that Yang Wanjun’s voice was still calm at the moment. After briefly describing his relationship with his cousin, he added, "My cousin liked to boss people around. Just imagine, he worked in a renovation company, fighting and arguing all the time, and he had to deceive and swindle people. Then he thought he understood society, but look how it turned out... Sigh, my aunt is the same, thinking that her way of educating is so great..."

Upon hearing this, Li Haochen couldn’t help but take out his notebook, flipped it open, and started taking notes: he has a strong desire to show off, and when mentioning the deceased and his mother, he exhibits strong emotions...

Liu Jinghui glanced at the notes and whispered with a smirk, "You’re jumping to conclusions a bit here."

"Based in part on Yang Wanjun’s Weibo and Moments," Li Haochen whispered. "He’s more arrogant when he speaks online than he is now."

Liu Jinghui raised an eyebrow. He often paid attention to the online presence of people involved in a case, but clearly, he wasn’t as dedicated to it as the younger Li Haochen.

At that moment, in interrogation room 3, the officer asked, "What were you doing when Liu Zhiwu disappeared?"

"I don’t remember clearly, probably just at work as usual, playing games or something," said Yang Wanjun, appearing extremely nonchalant.

The interrogating officer frowned seriously and continued, "Your own cousin goes missing, such a serious matter, and you don’t quite remember it?"

"Who remembers the exact time? It was so long ago. Plus, my cousin had complex dealings. It was normal for him to disappear for a day or two. By the time my aunt felt something was wrong and started calling around for him, several days had already passed," Yang Wanjun said with a convincing air.

Surveillance room.

Li Haochen frowned and said, "This Yang Wanjun clearly lacks experience in being interrogated, but he’s lucky in one aspect, he didn’t personally commit the murder, so he really doesn’t have much of a psychological burden."

"Doesn’t plotting the murder count?" Mu Zhiyang, who had been with Jiang Yuan for a while, bore some measure of abhorrence against evil.

Li Haochen hummed and said, "Legalities aside, just talking about personal psychology, the psychological burden of actually committing a murder and planning one are not on the same level."

"So you’re saying, planning a murder even helps him resist interrogation?"

"That’s about the size of it. However, if he truly is the mastermind behind this, the ending will be the same," Li Haochen didn’t believe an ordinary person could pass an interrogation test without training; relying on fabrications won’t get one very far.

Many people think they can lie calmly amongst friends, but that’s usually because their friends don’t call them out, or the lies are insignificant, and some friends are just carefree. But with criminal police, the purpose of taking statements is to record, and once all the made-up content is written down, any contradictions are unacceptable.

And after the police have grasped a portion of the facts, the chances of getting through an interrogation become even slimmer.

Someone like Yang Wanjun, even if his lies are tightly woven, would still face intense scrutiny.

"We’ve already sent people to search Yang Wanjun’s house, plus we’ve called in a computer expert to analyze his electronic devices. In a few hours, we’ll know everything about his online activities, whether he buys memberships or not," Cui Qishan said with a slightly ferocious smile, somewhat reminiscent of a domesticated wolf showing its feral nature.

Mu Zhiyang, thinking of something, hissed, "High-tech crime is not advisable."

"The victim’s mother is still praising Yang Wanjun," Wang Chuanxing reminded in a low voice. He was on a task and couldn’t just look at any surveillance room he wanted.

Hearing this, Liu Cheng switched the large screen to the victim’s mother’s perspective, and everyone adjusted their volume accordingly.

The victim’s mother was rambling on, "Wanjun is someone I’ve watched grow up. As a child, he was often sent to stay at my house during the winter and summer vacations. I paid for his school fees, helped him find a job, bought him a camera, furniture... Wanjun is a good kid. If only my Zhiwu were as obedient as him..."

"So, you’ve been giving Yang Wanjun long-term financial support? Why?" the interrogating officer asked.

The victim’s mother shook her head, "That wasn’t support, Wanjun is one of our Yang family. It’s only right for me to give him a bit of money, isn’t it?"

"What about your son?"

"My son is treated the same. He never lacked anything and used to play with Wanjun a lot when they were kids."

"How’s their relationship?"

"They got along well."

"And now? Do they see each other often?"

"We always gather as a family for holidays, and I often take my son back with me. He’s been busier these past two years, so he’s gone back less."

"In your will, your son Liu Zhiwu is the primary heir and Yang Wanjun is the secondary heir? Why is that?" the interrogating officer pressed further on the matter of interests.

The victim’s mother explained naturally, "Wanjun isn’t married yet. What I mean is, if I’m around, I could lend Wanjun money for his marriage. If I’m not, then I’d leave half the house to Wanjun, which should be enough for a down payment."

"Does your son agree with this?"

"Of course, he does. He doesn’t concern himself with my affairs and I haven’t spent his money," the old lady’s tone was very firm.

The people in the surveillance room looked at each other before hearing Cui Qishan softly say, "With a mother like that, it’s not surprising anyone could turn out to be a
