The sophomore season of MASTERMIND OF MURDER premiered on Sunday, July 17, 2022 at 7pm ET/PT on Oxygen. Every episode investigates a murder of an unsuspecting and beloved victim, with initial clues leading police to believe the person who committed the crime also devised the plot. However, when law enforcement furthers its investigation, everything's not as it seems. The person who committed the brutal crime isn't the one who carefully and deliberately orchestrated the hit, but is a pawn in someone else's plotting. As the twisted layers of cases are unraveled, the master manipulators behind the crimes are brought to light. Professions of love, bone-chilling threats and promises of riches are the tools used to persuade others to utterly devastate family and friends by taking their loved one's life. Deception among family members, a never-ending fight for land and an obsession with power are just some of the factors fueling the rage that leads people to construct murderous plans. It's easy to see the person who manipulates the perpetrator embodies as much evil as the one who commits crime. Season 2 episodes include:
