Rock star Gregg Allman’s recent lawsuit to block production of the movie about his life—filed after a film crew worker died in a train accident on the set—helped cement his role as a defendant in a wrongful death case brought by the worker’s parents.

Jeffrey Harris, who represents the parents of camera assistant Sarah Elizabeth Jones, said testimony in Allman’s legal fight with producers of the movie “Midnight Rider” showed Allman was very involved in the day-to-day operations of the film.
