OMAHA, Neb. (AP) — The first of five men charged in a deadly Tecumseh prison riot last year has been sentenced to a year in prison.

22-year-old William Harris pleaded no contest to a reduced charge of third-degree assault in the riot that killed two inmates, destroyed portions of the prison and injured two corrections officers and four inmates.

At the time of the riot, Harris was serving a 51- to 74-year sentence for assault and use of a deadly weapon in Douglas County.

Four other prison inmates were charged with assault and related charges following the riot. Law enforcement officials still haven’t arrested anyone in connection with the killing of the two inmates, Donald Peacock and Shon Collins.
