After Liu Gensheng resigned, he continued living in the company dormitory, going home only on weekends. During the incident, Liu Gensheng was at the company where he drove, with video and witness evidence, so he had no time to commit the crime.
Wang Yong's investigation results also quickly progressed.
Wang Yong resigned from Tianhong Chemical Transport and Storage Company two months ago, not because he found another job, but because his son had a child, and he went to help take care of it.
Wang Yong's son is in Haizhou City, not Tianzhou City, so Wang Yong has been living in Haizhou City for the past two months and hasn't returned.
With this, Wang Yong's possibility of committing the crime was directly eliminated.
That left the last person Lu Chuan suggested for thorough investigation, Zhang Zicai.
Third Mr. Zhang's Village is a small village in Quanshui County of Tianzhou City.
