Midnight Rider assistant director Hillary Schwartz has pleaded not guilty to charges of involuntary manslaughter and criminal trespassing in connection to the death of Sarah Jones on the set of the Allman Brothers biopic.

Schwartz, who became the fourth member of the movie's production group to be charged, was arraigned on Tuesday (30Sep13) at Georgia's Wayne County Superior Court.

A tentative trial date has been set for 9 March (15) for all of the defendants, who could face up to 10 years behind bars under Georgia law if found guilty.

Director Randall Miller and producers Jody Savin and Jay Sedrish have been hit with the same charges and have also pleaded not guilty.

Camera assistant Jones died after she was hit by an oncoming train while filming scenery footage for the movie on a trestle in Georgia back in February (14).

Several civil suits have been filed against Miller, Savin, Sedrish and others linked to the project, which was put on hold following the tragic accident.
