(AP) — A Nebraska inmate has pleaded no contest to manslaughter in the death of a Lincoln woman who was struck and killed by a state prison van he was driving.

36-year-old Jeremy Dobbe entered the plea Monday in the death of 47-year-old Joyce Meeks. She was killed on June 25 in Lincoln. A no-contest plea acknowledges there’s sufficient evidence to convict but is not an admittance of guilt.

Dobbe was seen speeding and swerving before he struck Meeks’ minivan. Dobbe was transporting inmates as part of a state work-release program.

Deputy Lancaster County Attorney Nick Freeman said that in exchange for the plea, the state agreed not to file additional charges.

Dobbe faces up to 20 years in prison when he’s sentenced in June.
