(AP) — A judge has dismissed a lawsuit brought by the family of a Nebraska inmate who died in 2010 while in custody.

The lawsuit was dismissed Thursday. Lancaster County District Judge John Colborn found there wasn’t enough evidence to show that state officials had been negligent in the death of 51-year-old Darryl Reed.

Reed died from heart disease and hardening of the arteries. He was serving a 5-to-8 year sentence for a drug conviction when he was taken from an Omaha prison to a prison infirmary in Lincoln because of behavior that led security staff to think he has used illegal drugs. Hours later, a nurse found him in distress, and he was taken to a Lincoln hospital, where he died.
