BOISE, Idaho (AP) — Prosecutors say a 35-year-old Boise man passed some three dozen phony $50 notes in Idaho, a crime that could mean he'll spend up to 20 years behind bars.

William W. Hanson pleaded guilty to one count of passing counterfeit bills on Monday in U.S. District Court in Boise. According to his plea agreement, on March 26, Hanson passed a counterfeit $50 note at a restaurant in Cambridge, Idaho. Hanson admitted to knowing the note was in fact a $5 note, bleached and altered to look like a $50 note.

A subsequent investigation revealed Hanson passed 35 counterfeit $50 notes in Burley, Twin Falls, Boise, Garden City, Nampa, Eden, Horseshoe Bend, Donnelly, McCall, New Meadows, Council, and Cambridge. Sentencing is set for Aug. 26 before U.S. District Judge Edward J. Lodge.
