SPOKANE — A former Yakima man was sentenced in U.S. District Court to 51/2 years in prison for distributing LSD.

A yearlong investigation showed that Allen Lint, 27, was a selling the hallucinogenic drug at regional barter fairs, federal prosecutors said in a Thursday news release. Authorities did not say where Lint was living when he was arrested.

He and another man, Palmer Hanson, sold LSD to undercover officers at the Spokane Valley Mall on July 26, 2007.

Palmer is scheduled to be sentenced later this month.
