The slaughterhouse owner was slightly overweight and had a bit of a double chin.
The interrogation chairs in the case center were all widened, and when he sat down, he filled every inch, as if not to waste any space.
As he talked about the homicide, the slaughterhouse owner was also nervous, with a touch of relaxation. Seeing this, Liu Jinghui's expression became grave.
He wasn't an actor; ordinary people couldn't fake that kind of expression unless they were preoccupied with serious concerns.
Liu Jinghui judged that he must be an important informant, and that the information he knew was probably not simple.
Liu Jinghui quickly glanced around, noticed Jiang Yuan and the others were present, and then turned to the slaughterhouse owner, saying, "Li Huigai, you claim you're not the killer, so do you know who is?"
After hesitating for a few seconds, the slaughterhouse owner, Li Huigai, said, "I know."
