Prosecutors are scheduled to go before the state Supreme Court this week to ask it to reinstate the conviction of Kennedy cousin Michael Skakel in the 1975 murder of Martha Moxley.
Skakel was convicted in 2002 but was freed in 2013 after a judge granted him a new trial in the slaying of Moxley, a Greenwich neighbor. Skakel is a nephew of Robert F. Kennedy's widow, Ethel.
The court found, in part, that Skakel's trial lawyer failed to argue that Skakel's brother could've been responsible for the crime and failed to present a key alibi witness for Skakel.
Skakel was sentenced to 20 years to life in prison.
He's currently free on a $1.2 million bond while awaiting a new trial.
The high court is scheduled to hear arguments Wednesday.
