Murder and Justice: The Case of Martha Moxley (7 p.m., Oxygen) - This three-night TV event, hosted by former federal prosecutor Laura Coates, explores the 1975 murder of Martha Moxley in Greenwich, Conn. Michael Skakel, cousin to the Kennedy family, was found guilty of the murder in 2002, but the conviction was reversed in 2013 when a judge ruled that Skakel’s original trial lawyer did not provide a competent defense. Did he do it? With the help of crime experts, Coates looks at the case’s original evidence and tests new theories that examine potentially overlooked clues. The case also explores the effects that money, privilege and media frenzy can have on a quest for justice. This will include interviews with those connected to the case, including former LAPD homicide detective Mark Fuhrman, attorney Mickey Sherman and Skakel’s cousin and advocate Robert Kennedy Jr. The next two parts air over the next two Saturday nights.
