CHEYENNE, Wyo. (AP) — The Wyoming Department of Corrections says a 58-year-old inmate has died after a lengthy illness.

The agency says Kevin B. Wallace died last Friday at the Regional West Medical Center in Scottsbluff, Neb.

Wallace was sentenced in April 2008 in Fremont County for two crimes to be served concurrently. He was sentenced to 13 and a half to 15 years for attempted sexual abuse of a minor in the third degree, and six to 10 years for interference with a peace officer.

A routine autopsy has been ordered.
