What are the official giants of Silent Witness?

The "Dianbingshan 1" case that shocked the whole country broke out in Yungang City. The case started with an ordinary murder case, and the same pit with buried bones was found in the depths of Dianbing Mountain in the suburbs. After forensic identification, it was confirmed that this was a serial murder case with a single technique that lasted for ten years. Almost all the victims were self-indulgent female college students. The whole Yungang city is shrouded in the shadow of terror.

Under the guidance of Liu Baosheng, an old criminal policeman, and inspired by Chen Junwei, an expert in criminal psychology, Ma Zhou, a young policeman, used the perspective of criminal psychology to find the culprit hidden in the vast sea of people. Their target is Yin Shi, who has a good family background and higher education, but has psychological problems because of power disputes in the family business. Yin Shi admitted his crime.

However, the loopholes in his confession attracted the attention of Liu Baosheng and Ma Zhou. As the case progressed, Yin Shi committed suicide before being sent to court. At this time, Liu Baosheng, an old criminal policeman, went to other places for investigation in the name of going to Beijing for a meeting, but he disappeared mysteriously, and the case was confusing again.
