OMAHA, Neb. (AP) — A 59-year-old dentist has been convicted of stealing dental gold and equipment when he worked at the Veterans Affairs Medical Center in Omaha.

A federal judge entered his ruling on Tuesday against Randall Toothaker. In December he’d pleaded no contest to theft. His sentencing is scheduled for April 9, and he faces up to 10 years in federal prison.

Investigators say Toothaker stole more than $16,000 in dental gold and equipment from a locked cabinet in 2013. An officer stopped Toothaker while he was leaving the property.

Toothaker’s attorney has said his client works for a dental group in Fort Dodge and wants to put the case behind him.
