s on several suspects in the name of research. The polygraph results showed that the suspects in Case 1.05, Case 3.12 and Case 7.21 did not speak on the issue of whether they committed murder.

This is a murder case, not any other case. The murderer will be sentenced to death, and a light sentence will also be a suspended death sentence!
Secretary Meng realized the seriousness of the problem, frowned and hesitated to speak, finding it difficult to accept all this. Deputy Director Huang and Deputy Director Song looked at Ying Chengwen at the same time, as if asking him if there were any problems with these cases.
I knew their drunkenness was not interested in drinking, but I didn’t expect such a big thing to happen.
Ying Chengwen was frightened. He took several deep breaths to calm down as much as possible. He quickly recalled the facts of these cases. The more he thought about it, the more he thought there was no problem. He subconsciously asked: “Director Han, where is the 12.28 case?”

He can’t find a job, and he looks a bit like a homeless person on the outside, so he can’t be compared with other murder cases.”
As long as it is a murder case, Ying Chengwen has been to the scene of almost every case and has directed the investigation. He knows the case very well and is convinced that there is nothing wrong. Starting from these two cases, I want to eliminate all those that the provincial department thinks are problematic.
