A man accused of killing a Roman Catholic priest and taking the victim's car on a vacation to Walt Disney World has been found dead in a Mississippi prison cell with a sheet wrapped around his neck.

Thirty-three-year-old Jeremy Wayne Manieri was charged with shooting the Rev. Ed Everitt in July 2011 at a beach house in Waveland, Miss.

Manieri's attorney, Brian Alexander, said he was told that Manieri was found early Thursday at the Central Mississippi Correctional Facility near Jackson with a sheet around his neck. Alexander said he was trying to gather more information and would comment later.

Rankin County Coroner Jimmy Roberts said an autopsy was being performed Thursday. Prison officials called it a "possible suicide." They would not comment further.
