Criminal Case: Mysteries of the Past

Victims are supporting characters who are killed for reasons that must be exposed in each individual case.

Suspects are supporting characters who are suspected of either the murder of the case's victim or any shady crime as the police force sees as being fit,whether they turn up as innocent or guilty of the crime.

Quasi-suspects are characters that are not suspects, but require a star to converse with in the Additional Investigation. Often to gain more leads.
