The U.S. Supreme Court has denied certiorari in Connecticut v. Skakel, leaving in place a state Supreme Court decision that vacated Kennedy cousin Michael Skakel’s conviction in the 1975 murder of Martha Moxley.

Represented by Bridgeport attorney Michael Fitzpatrick, Michael Skakel successfully argued in May that he was denied a fair trial, after being charged in 2000 and convicted in 2002 for beating 15-year-old Moxley to death with a golf club. Skakel, who was also 15 at the time of the murder, was Moxley’s neighbor in the Belle Haven section of Greenwich.
