A man once charged in a double murder at a bar has himself been shot to death outside another tavern in southwestern Pennsylvania.

Police have charged 36-year-old Nathaniel Jones, of Monessen, in the shooting early Sunday of 44-year-old Carl Anthony Cohen outside a bar in Canton Township. State police say Jones is hospitalized with unspecified injuries and being held under guard.

Cohen and two other men were charged with robbing and killing two men, Fred Brilla and Martin Brahler, inside another Washington County bar on Nov. 4. 2003.

Cohen and another suspect pleaded guilty to lesser charges of robbery and had the homicide charge against them dropped in exchange for testifying against the third suspect, Gerald Gregg, also of Canton.

Gregg was acquitted.
