"What is this?"

"This is a powerful evidence for Xiaoyu's case."

Bai Yaqing looked at this USB flash drive suspiciously, this is the most powerful evidence? Could it be that someone witnessed it with their own eyes? Then why don't you save Xiaoyu?

Bai Yaqing frowned and looked at Liu Muduan suspiciously, not understanding. If someone really witnessed it with their own eyes, why is they so cold-blooded, preferring to record a video rather than save someone, even if it is to call the police......

"You don't have to look at me like this, here is the data of the monitoring equipment......" Liu Muduan told Bai Yaqing about the process of the matter.

After hearing this, Bai Yaqing felt that her luck was really good, and she also thanked Uncle Li Wei for his help, otherwise the progress of solving the case would not be so much faster.

………………

The next morning, Bai Yaqing sent the USB flash drive to City B.

She came back here yesterday because of something, and Zhang Zijun was still on crutches in the hotel in City B.

"Zhang Zijun."

"You called last night to say there is new evidence, what is it?"

"You know it when you see it." Bai Yaqing gave him the USB flash drive.

Bai Yaqing hadn't seen this USB flash drive, because it was a little late yesterday, so he went to bed directly.

Zhang Zijun looked at the USB flash drive and plugged it directly into the computer.

Liu Muduan was right, it was the surveillance video, which happened to be the floor where Xiaoyu lived.

It can be seen that after that person went up to this floor, he directly took off his clothes and changed into the clothes in a black bag. And the black bag, which was placed there early in the morning, may have been premeditated for a long time.

This outfit is exactly the same as the person who destroyed the surveillance camera, and even the body shape is exactly the same!

I saw that he had been squatting there, and this time period should have been after Li Wei left.

Bai Yaqing looked at the time, Xiaoyu usually had time to go home if she didn't have any activities.

Sure enough, it didn't take long for the man to go out with a stick and never returned......

"That's the person, hand it over."

"This can only prove that he destroyed the surveillance equipment, and if he does not admit to the killing, we have no way to convict him......," Zhang Zijun analyzed.

"So what now!?"

"Let's hand this over first."

………………

The next day, the man was arrested.

The Forensic Identification Division found a set of fingerprints in the discarded bag, which was discovered by the cleaning staff and called the police, so no one else touched it; And his neighbors also testified that in the middle of the night, about four o'clock, before the body was found, he heard the sound of chopping things next door, which lasted until dawn......

And the comparison of that set of fingerprints immediately confirmed the identity of the murderer, and the testimony of the surveillance video was enough to capture him.

During the interrogation, Bai Yaqing watched from the observation room next to the interrogation room, looking at the person through the one-way glass.

Her eyes were full of murderous intent, her hands were clasped around her chest, her fists were clenched tightly, and she gritted her teeth and held back.

She was afraid that she would not be able to control herself, and she would rush over and kill the murderer!!

"Why did you kill the dead?"

"I didn't kill her."

The murderer denied it, very calmly, without the slightest flaw.

"This is a trash can near your house, the knife that was found, it has been curled, and there is the blood of the deceased and your fingerprints on it, what is the explanation?"

"You said that the blade is curled, how can you kill someone?"

Bai Yaqing's eyes were red, this person was simply quibbling!
