A TRUE crime documentary examining one of Jersey’s most infamous murder cases is due to air on Sky and features previously unheard tape recordings.

The three-part series explores the investigation into the Newall murders in October 1987.

Nicholas and Elizabeth Newall were bludgeoned to death in their St Brelade home in October 1987 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.

The newly confirmed documentary is called Inheritance: The Jersey Murders and has been six years in the making, according to online site Deadline Hollywood.

The entertainment and media news provider said the three-part series, which will be broadcast next month, features unheard taped recordings between the brothers and offers new insights into their actions and motivations.
