ST. LOUIS (AP) — A former St. Louis County sheriff’s deputy faces up to a decade in federal prison now that he’s admitted collecting $95,000 in undeserved income from a library where he worked as a security officer.

Alvin Wilson pleaded guilty in St. Louis to theft from an organization that receives federal funds. His sentencing is set for Sept. 22.

Authorities say Wilson was employed as a deputy sheriff when he also worked as a St. Louis Public Library security officer from 2012 through last year.

Prosecutors say Wilson falsely reported hours he worked at the library and was paid for them, at times working as a deputy or at home when he was supposed to be providing security.
