Producers of ill-fated Gregg Allman biopic Midnight Rider: The Gregg Allman Story have turned themselves in to police and spoken out over the death of a camera assistant that shut down production.

Director Randall Miller, writer/producer Jody Savin and producer Jay Sedrish have been charged with involuntary manslaughter over the death of Sarah Jones, 27, who was struck and killed by a train during shooting of the film in Wayne County, Georgia back in February.

Miller and Savin, who are husband-and-wife, have insisted that they haven't committed a crime and aren't responsible for Jones's death, but say the tragedy "will haunt us forever."

The two filmmakers were indicted on charges of involuntary manslaughter and criminal trespass and were later released on bond.

"In the weeks and months that follow when the true facts of the events are revealed, people will know that this was not a crime: we never had criminal intent; we would never knowingly or intentionally put anybody's safety at risk. This was a horrible tragedy and a horrific accident," the couple said in a joint statement.

"We have remained silent out of respect for the family of Sarah Jones, their loved ones and all of the crew who were injured on that very sad day," the statement reads. "Our hearts are broken, our spirits are broken. We have young children and can only imagine with immense sadness the heartbreak of losing a child. We are praying for Sarah's family."

The couple turned themselves in to police on Sunday and pleaded not guilty to the charges.

Sedrish finally turned himself in to Georgia police on Thursday, but has yet to make a statement.

The crew of the film was shooting a scene on a train trestle when the incident occurred, and Jones couldn't escape the oncoming train.

The three filmmakers face up to 10 years in prison each, and civil suits against the trio have also been filed. The film has since been put on hold, and even Allman himself has pushed for it to be scrapped entirely.
