"However, when we looked through the surveillance video frame by frame, we realized that the person with the problem was not your brother, but lawyer Chen, who had met you before him.
We slowed down the camera and zoomed in. We found that Mr. Chen secretly put a pill into your cup when the interrogating police officer wasn't paying attention."
There were surveillance cameras in every interrogation room in the police station. However, Zhan Jia 'er was the victim back then and not the suspect.
Therefore, no one would deliberately slow down the camera to pay attention to the situation in her interrogation room.
Lawyer Chen had come prepared. He merely raised his hand to look at his watch and threw a small white pill into the warm water that Zhan Jia 'er was drinking.
The pill dissolved in the water.
At that time, Zhan Jia 'er was crying and hiccuping. The female police officer at the side picked up the cup of warm water and let her drink it.
