Prosecutors Seeking Reinstatement of Kennedy Cousin Michael Skakel's Conviction for Teen's 1975 Slaying

Attorney Stephen Seeger tells PEOPLE it could take several months for seven Supreme Court justices to render a decision following Wednesday's appeal hearing in Hartford.
Skakel, 55, was released in 2013 after a judge granted him a new trial in Moxley's killing.
Skakel is a nephew of Robert F. Kennedy's widow, Ethel, and was Moxley's neighbor in Greenwich, Connecticut, when the 15-year-old girl was bludgeoned to death with the shaft of a broken golf club.

A judge ruled two years ago that Skakel's trial lawyer failed to adequately represent him during the 2002 trial, which resulted in a 20 years to life prison sentence.
Skakel was freed on November 21, 2013 after posting $1.2 million bond. He is required to wear a GPS monitoring bracelet as a condition of his release.
Prosecutor Susann Gill did not return calls seeking comment Tuesday.
Skakel’s cousin, Robert F. Kennedy, Jr., has written a book about the case called Media Lynching: The Persecution of Michael Skakel. The book is due to be released in April.
