LINCOLN, Neb. (AP) — A prisoner who helped two other inmates escape a Lincoln prison has been given more time behind bars.

Court records say 27-year-old Brandon D. Williams was sentenced to three to four years in prison — time that will be added to the 10 to 15 years he’s already serving for a robbery in Douglas County. He’d pleaded no contest in the escape case.

Prosecutors say that on June 10 last year, Williams helped Lincoln Correctional Center inmates Timothy Clausen and Armon Dixon hide in a laundry cart before rolling the cart into a laundry truck that was headed to another prison.

They escaped from the truck after it left the center. Dixon was caught the next day in Lincoln, and Clausen was caught five days later at an Omaha apartment.
