A few minutes following both investigations, the members of the LSI have reconvened with each other to discuss their findings. Jinshu, the construction worker believed to have no connection to the events, was revealed to be an assassin in the past as well as Liu's true father. Meanwhile, Nima, the school teacher who overhead the accident, was revealed to having an indirect connection to Jinshu via a fight between her husband and Jinshu.

Who killed Liu and for what possible purpose?
