(AP) — Relatives have sued the state over a fatal Lincoln collision that involved a state-owned van driven by a Nebraska inmate.

The lawsuit was filed last week against the state and the inmate driver, 36-year-old Jeremy Dobbe. He has pleaded not guilty to a manslaughter charge and awaits trial.

Joyce Meeks’ husband, Leonard, and son, Martell Buchanan, say in the lawsuit that the state was negligent for letting Dobbe behind the wheel of the van that hit Joyce Meeks’ vehicle on June 25 last year.

The Nebraska Department of Correctional Services has since ended the prison-driver program, which allowed inmates to transport other prisoners to and from work-release sites.
