Authorities are searching for an inmate who went missing from a minimum-security prison in Yankton.
Corrections officials say Richard Beckwith signed out of the Yankton Minimum Unit to go to a work release job Sunday morning and never arrived at the job site.
Beckwith is 51 years old. He is white, 5-feet-9 inches tall and weighs 145 pounds. He has brown hair and brown eyes.
He was sentenced in 2006 to 9 years, 10 months in prison for possession of a controlled substance on a drug conviction in Minnehaha County.
