"Of course, it's also possible he bought it with cash. In any case, investigate as thoroughly as possible. I think this is a major breakthrough."
"If we ultimately can't find any evidence in Han Xiaolong's case, then perhaps we can use Yang Maocai to convict Zhou Hui."
A fatal hit-and-run is considered a traffic offense, carrying a sentence of seven years or more.
However, if it was a premeditated plan to kill someone with a car, that's a completely different situation. That's intentional homicide, which carries the death penalty.
So, Liu Jie's idea was that if they couldn't find evidence in the Han Xiaolong case to convict Zhou Hui, they could rely on Yang Maocai to get a conviction.
As long as it's the death penalty, the outcome is essentially the same.
The investigation continued.
Just as Liu Jie said, the more moves Zhou Hui made, the more tells he would reveal, giving them more avenues to investigate.
Another discovery was made that day.
It was the surveillance footage.
