Two of the three producers of the Gregg Allman biopic have surrendered to Georgia police on charges of involuntary manslaughter. The charges stem from the on-set death of camera assistant Sarah Jones five months ago.

TMZ is reporting that director Randall Miller and his wife, Jody Savin, turned themselves in to the Wayne County Sheriff's Department. They were released roughly an hour later after posting $27,000 each. The third member of the production team, executive producer Jay Sedrish, is still at-large.

Jones was killed Feb. 20 when a train unexpectedly arrived across a trestle where they were preparing to shoot a dream sequence. Seven others were injured in the accident. In the aftermath, actor William Hurt, who was cast in the lead role, left the movie and Allman attempted a lawsuit to shut down the production.

Two weeks ago, a grand jury returned an indictment against the trio for involuntary manslaughter, which carries a maximum 10-year sentence, and misdemeanor trespassing. Reportedly the producers were working at the location without a permit. All three -- and Allman, who is listed as one of the film's executive producers -- are also facing a wrongful death civil suit from Jones' parents.
