Nicholas and Elizabeth Newall were bludgeoned to death in their St Brelade home in a crime which shocked the nation.
Their sons, Roderick and Mark Newall, were in their early 20s and inherited £900,000 after their parents' deaths. They were later convicted for their involvement in the murders and cover-up.
Roderick, a former British Army officer, received a life sentence for double murder, while Mark, an international banker, was convicted of assisting an offender and concealing the bodies.
Inheritance: The Jersey Murders explores the investigation into the Newall murders in October 1987, which features unheard taped recordings between the brothers and offers new insights into their actions and motivations.
