SAVANNAH — Singer Gregg Allman was sued Wednesday along with movie producers, a railroad company and others accused of being responsible for the February death of a young camera assistant when a freight train slammed into a film crew in southeast Georgia. The lawsuit filed in Chatham County State Court by the parents of 27-year-old Sarah Jones targets 10 individuals associated with the film "Midnight Rider," based on the Allman Brothers Band singer's memoir. It also goes after eight corporations including CSX Transportation, which owns the railroad tracks where the crash occurred, and Rayonier Performance Fibers, a subsidiary of forest-products manufacturer Rayonier that owns the land surrounding the crash site.
