Ethel Kennedy, who lost her husband Robert F.

Kennedy cousin Michael Skakel is suing a police investigator and the town of Greenwich, Connecticut, more than five years after his murder conviction was overturned.

Michael Skakel, right, appears for his hearing at Stamford Superior Court, with his attorney Stephan Seeger, Friday, Oct. 30, 2020, in Stamford, Conn. A Connecticut prosecutor says Kennedy cousin Michael Skakel will not face a second trial in the 1975 murder of teenager Martha Moxley in Greenwich. Skakel, a nephew of Robert F. Kennedy's widow, Ethel Kennedy, did not speak during the hearing or outside the court. On the night of the killing, Martha Moxley, 15, and other teens in Greenwich's Belle Haven neighborhood were out doing pre-Halloween pranks, police said. At the 2002 trial, prosecutors presented several witnesses who said they heard Skakel confess or make incriminating statements. One of those witnesses, Gregory Coleman, died from heroin use by the time Skakel’s trial began.
