LINCOLN, Neb. (AP) — An investigator says an inmate helped two others escape a Lincoln prison in a laundry truck.

Nebraska State Patrol investigator Cory Townsend testified at a hearing Tuesday that the inmate piled clothes atop Timothy Clausen and Armon Dixon, who’d climbed into a laundry cart on June 10. The cart was then loaded into a truck used to haul laundry from the Lincoln Correctional Center to another state prison.

Authorities have said the two ripped a hole in the truck’s roof, climbed out and jumped off for a brief span of freedom. Clausen and Dixon were recaptured within a week.

The third inmate hasn’t been charged. A judge decided Tuesday that Clausen and Dixon will be tried on escape charges.
