As a local policeman, is it appropriate for you to take over the job of a criminal policeman?

"Comrade Niu Xiaowei, please accept my condolences. We are here to understand what happened last night so that we can catch the murderer as soon as possible. Can you speak now?" Chief Li asked. Recording a confession requires the consent of the person involved, and since Niu Xiaowei was in this state, Chief Li was not sure if he could record it.

"I can do it, just ask." Niu Xiaowei nodded slightly and said with pursed lips.

"This is Captain Ye Linye of the Criminal Investigation Brigade of the Branch. He is here to ask the main questions. Please try to think about it."

"Ah."

Ye Lin and Li Suo sat down and started asking questions.

"Can you tell me briefly what happened last night?" Ye Lin asked.

Niu Xiaowei had a thoughtful look on his face, and after a while he slowly said, "I had a midnight snack outside last night and came back home after eleven. The lights were off at home, and my parents are old and go to bed early, so I didn't think anything of it."

"Wait a minute, did you use the key to open the door yourself, or was the door already open?" Ye Lin interrupted him.

"This?" Niu Xiaowei was silent for a while and began to think.

hiss--

Niu Xiaowei cried out in pain, gently supported his head, and a painful expression appeared on his face.

"My head hurts a bit, and I don't quite remember whether I opened the door to go in or whether the door was already open. I drank several bottles of beer last night, so I can't remember clearly."

Ye Lin nodded and motioned him to continue. It was normal that he couldn't remember some things clearly after suffering such a serious injury, and it would take some time to recover.

"After I went in, it was pitch black inside, so I just wanted to turn on the light in the dark, and then..."

"Then I seemed to be hit on the head and I passed out."

"Didn't you see anyone?" Ye Lin asked.

"No, I was drunk and I couldn't find the switch after trying twice, and then I was knocked out."

"and after?"

"When I woke up, it was already daybreak. I found a knife stuck in my stomach and a lot of blood. My parents were also lying on the ground, so I called the police."

After Niu Xiaowei finished speaking, Ye Lin was a little disappointed. The only survivor remembered nothing and the clues he provided were of no help in solving the case.

"Are there any valuable items in the house? Have you seen if anything is missing?" Ye Lin continued to ask.

"Yes, police officer, my father hid some gold at home, about one kilogram, and I don't know if it is still there." Niu Xiaowei suddenly remembered.

"Do you know where you put it? I'll have someone look for it right away." Chief Li interjected. If valuables were lost, there would be many more clues to the case, such as motives, selling stolen goods, etc., and there would be a direction to solve the case.

"There is a cabinet in the living room, not very eye-catching, with a lock on it." Niu Xiaowei described the general appearance.

"Your parents put such valuable things in the living room?" Ye Lin asked curiously.

"They said the more dangerous the place, the safer it is." Niu Xiaowei muttered softly, "I also tried to persuade them, but they didn't listen."

Li went outside to make a phone call to confirm. Ye Lin then asked, "Does your family have any enemies? Or have you had any grudges with anyone recently?"

Niu Xiaowei shook his head. "No, my parents are not that kind of people. They don't go out that often. My dad occasionally chats and drinks tea with old friends, and my mom dances with people downstairs. It's nothing."

"What about you? Are you married? Do you have any grudges with anyone?" Ye Lin asked, looking at him with a slightly scrutinizing look.

Niu Xiaowei's face changed slightly, and he explained: "I opened a company and did some small business. I can't offend anyone, and I don't have a girlfriend for the time being."

Looking at Ye Lin's stern eyes, Niu Xiaowei felt a little panicked. He thought that he would not be found to have borrowed money from loan sharks. His mind raced and he suddenly remembered something.

"Oh, by the way, just yesterday afternoon, when I came back, my dad had just had an argument with someone in the neighborhood, with a food delivery man."

Ye Lin's expression froze. It was the delivery man again. The previous case of Zhang Liqin was also somewhat related to the delivery man.

Seeing that Ye Lin seemed interested, Niu Xiaowei quickly continued, "Just yesterday afternoon, my dad was driving back and the delivery man scratched his car, and he refused to admit his fault. When I came back, I saw my dad arguing with him, so I went to help. I originally wanted him to pay compensation, but then it rained heavily, so I let it go."

Niu Xiaowei chose not to mention the incident in which Niu Jianmin forced the delivery guy to stop.

"Comrade police officer, do you think this delivery guy wanted to take revenge on us and came to kill people at night?" Niu Xiaowei asked weakly.

It would have been better if Niu Xiaowei didn't ask. After asking, Ye Lin immediately felt that there was something wrong here. How could an ordinary person think of killing someone after a quarrel?

His face darkened and he asked sternly, "Just because we had a quarrel and didn't pay any money, he wants to kill you? Are you hiding something else? Tell us everything so that we can solve the case as soon as possible."

This half-scare, half-question really frightened Niu Xiaowei, and he looked unnatural.

After looking at Ye Lin, he honestly told him about how Niu Jianmin forced the other person to stop, and also about how the takeaway was scattered, including how he scolded the delivery guy.

Ye Lin wrote them down one by one, and then said calmly: "We will investigate these things again, but if you deliberately conceal them, it will make it very difficult for us to solve the case, understand?"

"I understand, I understand." Niu Xiaowei replied weakly.

As soon as the voice fell, Li Suo came in and said solemnly: "The gold is gone."

When Niu Xiaowei heard this, he was so excited that he almost got up, but the wound on his stomach was pulled. He cried out in pain and lay down again. Sweat broke out on his forehead due to the pain.

"Be careful." Li Suo was so scared that he quickly helped him up.

"Comrade police officer, so much gold is gone? That's what my father saved for many years. It's worth a lot of money." Niu Xiaowei cried out in pain.

Ye Lin made a rough estimate. If it was one kilogram of gold, based on the current price of more than 500 yuan, it would be worth more than 50 yuan, which is a huge amount of money.

The nature of this case was even more serious. He looked at Chief Li, who also had a depressed look on his face. This kind of burglary, murder and robbery was definitely a major case and the whole city would be supervising it.

"Do many people know that you have so much gold in your family?" Ye Lin asked.

Since so much gold is missing, the motive of this case is most likely these properties, a typical case of murder for money.

In this world, no matter who has so much gold, no one would tell others about it, so if we find someone who knows the inside story, the case will be half solved.

Niu Xiaowei began to frown and think about it. Not many people knew about gold, but not too few either. Relatives would sometimes communicate with each other.
