Tonton Streaming Partners for Justice (2018) S1E16 - Episode 16

Do Nam and his wife mourn heavily over the loss of their son, Sung Jae. Initially, Sung Jae is believed to have fallen from a building. However, judging by the absence of blood at the crime scene and how the top of his head hit the ground first, Beom and the crew suspects this to be a homicide, not an accidental fall.
