GERING, Neb. (AP) — A former Kimball city councilman has been sentenced to 14 to 20 years in prison for attempted sexual assault of a teenage boy.

Forty-nine-year-old Scott Haun was sentenced on Monday in Scotts Bluff County District Court in Gering.

He was charged in October with first-degree sexual assault. He pleaded no contest to the lesser charge in April.

Haun was on the Kimball City Council for 12 years. He resigned prior to his plea hearing.

Authorities have said he admitted to performing a sex act on the 14-year-old boy while visiting the boy’s mother in rural Scotts Bluff County. The boy’s mother has said her son is mentally disabled.
