Michael Skakel, Kennedy cousin whose conviction in 1975 killing of Martha Moxley was overturned, files lawsuit

Kennedy cousin Michael Skakel, whose murder conviction in the 1970s killing of a teenager in Connecticut was overturned, is suing the lead police investigator in the case and the town of Greenwich for alleged malicious prosecution, civil rights violations and other claimed wrongdoing. The case made headlines worldwide and was the subject of the "48 Hours" episode "The Diary of Martha Moxley."

Skakel, 63, a nephew of Robert F. Kennedy's widow, Ethel Kennedy, was found guilty in 2002 of the 1975 bludgeoning death of Martha Moxley, who lived across the street from the Skakel family in wealthy Greenwich and whose body was found in her family's backyard. Both Skakel and Moxley were 15 at the time of her death.

"It was devastating. You have no peace. You've lost it all," Martha's childhood friend Tori Holland told "48 Hours" correspondent Erin Moriarty in 2021.
