"Yes...... It was probably around seven o'clock the night before yesterday and came back after eight o'clock......" Liu Zhijin's colleague thought about it and said.

"Are you sure?" Bai Yaqing asked.

Bai Yaqing needed a definite clue.

"Because we usually eat in the hotel, we have a cafeteria."

"You mean, Liu Zhijin went out to eat the night before, right?"

"Yes, he went out alone."

Bai Yaqing thought about it carefully, when An Leizhu's body was found, the forensic doctor thought that the time of his death was nearly twelve o'clock. But it was later confirmed that it was eight o'clock, because the temperature at the scene was extremely low, and it should have been the murderer who turned on the air conditioning in the entire living room after the killing......

And the night before yesterday, that is, on the day of the crime, although Liu Zhijin was working overtime, he went out alone at the time of An Leizhu's death.

According to the distance from here to An Leizhu's house, these times are enough. As for Liu Zhijin's going out to eat, in fact, it doesn't matter if people don't eat at night, he can go out and kill people and come back, just say that he just came back from eating.

"Thank you for your cooperation."

From here to the street of An Leizhu's house, there should be surveillance, and after Bai Yaqing came out of the hotel, he came directly to the neighborhood committee of this district.

Neighborhood.

"Hello, I'm a police officer from the serious crime group in City A."

"Oh, comrade policeman, how can I help you?"

"That's right, I need to investigate a piece of surveillance, please help me."

"Yes, when?"

"From 7 p.m. to 10 p.m. the night before yesterday, the street from the hotel to here was monitored." Bai Yaqing pointed to the area on the map and said.

The staff of the neighborhood committee immediately started their work, and they were already transferred out in less than half an hour.

"Hello comrade policeman, it's been transferred out, take a look."

On the surveillance video, Liu Zhijin was indeed seen, he walked from the street of the hotel to the street of An Leizhu's house, and when he reached that neighborhood, he was gone. At around eight o'clock, Liu Zhijin reappeared on the street of An Leizhu's house, but there seemed to be a black bag in his hand, and there was no trace of blood on the clothes on his body, but it seemed that he had changed a set of clothes......

Because this suit looks a little loose, An Leizhu's body is slightly stronger than him......

The black bag should be the murder weapon. The black bag was thrown into a trash can on the street next door to the hotel.

I am afraid that the one that was lost the night before was now collected from the garbage dump......

"Can you please give me a copy of this?"

"Yes, is there a USB flash drive?"

When handling cases, Bai Yaqing always carried the things she needed at any time, and took out a USB flash drive from her pocket.

"I'm sorry for you."

After coming out of the neighborhood committee, Bai Yaqing was worried about how to find the murder weapon, and when it turned out that Liu Zhijin had killed someone, the police station called.

If there is no murder weapon, based on the surveillance video, it can only prove that Liu Zhijin has been there, and it may be that he has passed by, but it cannot directly prove that he came to kill people.

The call from the police station was about the murder weapon.

This morning, when the sanitation workers were working, they found a black bag next to the garbage can, opened it and saw that it was a knife with blood on the blade, and immediately called the police......
