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

At 12 o'clock in the night, the Criminal Investigation Brigade was still brightly lit. It was already the early morning of July 7, the fourth day after the Zhao Youquan case occurred.

Yu Haifeng was making the final summary of the report.

"This is the forensic report. It is exactly the same as Zhang Yuli's confession."

"The deceased, Wang Yamei, died between 7 and 3 p.m. on July 8. The cause of death was a sharp weapon piercing her heart and her face was slashed multiple times by the weapon."

"According to the comparison, the murder weapon was a sharp knife. According to Zhang Yuli's explanation, it was the beef knife in her store."

"All the circumstances are consistent with what Zhang Yuli said. It is basically confirmed that Zhang Yuli is the murderer of this homicide."

When everyone heard that the murderer had been identified, they applauded happily. They were excited that a murder case was solved so quickly.

After everyone was happy for a while, Yu Haifeng continued, "Don't be too happy. This is Wang Yamei's murder case. We are investigating Zhao Youquan's unsolved case, and there has been no progress in this case."

After Yu Haifeng said this, everyone fell silent. Yes, the most important case has not been solved yet.

"Captain Yu, I think this case should be related to Zhao Youquan's case. It's such a coincidence." Ye Lin said.

"Linzi, please continue, let us listen."

"Look, both cases happened on July 7rd, at night, one around 3pm, the other around 8am, and the murderers were both women."

"Look at the murder weapons again. They are all sharp knives. Qi Shan, get the sharp knives from Zhao Youquan's case."

Qi Shan quickly retrieved the information from the computer and put the two knives together. Although the murder weapon in Zhao Youquan's case was not found, a simulation was made based on the shape of the wound, and the simulated murder weapon was the same as the knife used by Zhang Yuli.

"That's true. It's possible that it's the same knife." Old Zhao on the side agreed.

Ye Lin continued, "Also, let's take a look at the surveillance footage of Zhao Youquan's case. His back view is similar to Zhang Yuli's."

Yu Haifeng suddenly woke up, "Are you saying that Zhang Yuli killed Zhao Youquan?"

Everyone exclaimed, how could it be such a coincidence that one murderer solved all the cases?

Ye Lin touched his nose, frowned and said, "It's hard to explain, but I just feel that there is some connection here, a very strange feeling."

"No, Captain Ye, it seems like it might have been done by one person." Wang Longxin said excitedly, then took out a map and pointed to the route on it.

"Look, it takes about an hour to get from Wang Yamei's home to the hotel where Zhao Youquan died. Zhang Yuli has plenty of time to change into a new set of clothes and then go get a room with Zhao Youquan."

"That's right." Old Zhao slapped his thigh and interrupted, "It is said that beheading is a technical job. Think about what Zhang Yuli does?"

"She's in the beef business. I asked around when I went to the store. She used to sell beef in the market, and she cut it herself."

"Judging from the way they sell meat, they must have a good understanding of the human body structure. There must be a problem if they chop off the head." Old Zhao said loudly.

"No, Lao Zhao, they are selling beef. What does it have to do with the human body structure?" Wang Longxin started to get serious.

Old Zhao snorted disdainfully, "What do you know, kid? How different are our bodies from those of cows and sheep? Our bones are the same."

"I'm telling you this. If you can kill a pig, you can definitely kill people?"

"of course."

The two began to argue from all angles, and in the end they didn't know what they were talking about.

"Okay, since we have this suspicion, we will continue to interrogate Zhang Yuli."

When Zhang Yuli was brought up, she looked much more haggard than before. Her fate was already sealed, and she no longer had any ideas.

"What? I've explained everything so clearly. Do you have anything else to ask me?" Zhang Yuli smiled meaningfully.

Ye Lin stared at her straight in the eyes, "Zhang Yuli, where did you go after you killed Wang Yamei?"

Zhang Yuli remained silent and just smiled.

"I hope you will cooperate with the investigation honestly." Ye Lin scolded.

"Where do you think I should go?"

"We already have a lot of clues in our hands. There's no point in you hiding it any longer. Now we're giving you a chance to make a fresh start."

Zhang Yuli curled her lips and sneered, "Reform? Don't you already have clues? Do you think I still have a chance to reform?"

"I asked you to explain something. Don't be so talkative. Where were you around 7:3 a.m. on July 12? Tell the truth!"

"Just as you thought, I went to find Zhao Youquan again that night, checked into a hotel with him, and then killed him." Zhang Yuli said indifferently.

This attitude surprised Ye Lin a little, and the confession of the crime was a bit too straightforward.

It always feels wrong when things go too smoothly.

"Then tell me, how did you kill him?"

Zhang Yuli raised her head and looked at the ceiling. "How to kill? Kill with a knife."

"I made an appointment with him to book room 305 at the Jiayue Hotel, and then I killed him after I went in and chopped off his head. It was that simple." Zhang Yuli said lightly.

Ye Lin was a little surprised, not because of her attitude, but because she was right.

Zhao Youquan’s case has spread, but many details are unknown to others, such as Room 305, at least the ordinary people don’t know it.

"Okay, you said you killed him, what did you use?"

"It's that knife, the one used to kill Wang Yamei. It's easy to use."

"Don't you love him very much? Why do you want to kill him?"

"No reason. When I saw him, I remembered him being with that bitch, so I killed him in a fit of rage."

"Please describe the details at that time, where was he and how did you kill him?" Ye Lin didn't believe it. Could it be that she really killed him?

"Details? What details are needed to kill someone?" Zhang Yuli pursed her lips.

"He went to take a shower, and then I went in and stabbed him to death and cut off his head."

So far, everything Zhang Yuli said was correct. Ye Lin looked at Yu Haifeng in surprise, and Yu Haifeng also looked incredulous.

"What about the head? Why did you cut it off? And where is it now?"

"I was upset when I saw his face, so I just chopped off his head. I used to sell beef in the market, so chopping off heads was easy for me."

"After I chopped off the head, I took it away. I originally wanted to find a place to feed the pigs, but then I thought it would be troublesome, so I just threw it into the river." Zhang Yuli finished her words calmly.

Everything clicked.
