Xiao Jin, a newcomer to the special investigation team, and his senior Lao Li were appointed to investigate the recent murder of a couple.
The scene was a secret room, and there was a power outage for ten minutes during the time of the crime. It was expected that the crime occurred during this time, but the surveillance at the building's exit did not capture anyone entering or exiting the building. Therefore, the downstairs resident who discovered the scene and had an emotional dispute with the couple became the first suspect.
Intention: Know the law and abide by it, be independent and independent.
