Man Responsible for Largest Bank Robbery in Wyo History Sentenced

A sixty-year-old man from Idaho was sentenced to 30 years in Federal prison for the largest bank robbery loss in Wyoming history.

Donald Alexander Sheriff was sentenced by the US District Court for bank robbery and the use of a firearm at a Green River bank in 2013.
He was ordered to pay over 170 thousand dollars in restitution costs after taking 175 thousand dollars from the bank.

This robbery was more sophisticated than a “typical” bank robbery as Sheriff had “cased” the bank prior to conducting the robbery; he wore a fake beard as a disguise and latex gloves in an attempt not to leave fingerprints or DNA.

He also wore an earbud connected to a police scanner enabling him to hear local police calls. Prior to the robbery, Sheriff had disabled the rear lock of the credit union, forcing the victim teller to a door where he was lying in wait.

Upon her arrival at the door, Sheriff confronted the victim teller, produced a firearm, and forced her inside the credit union. He then made her deactivate the alarm and open the vault. He emptied the vault and placed the money inside a garbage bag.

Sheriff then made the victim teller lie on the floor, where he used flex ties to bind her hands behind her back before binding her feet together. Sheriff was in the credit union less than ten minutes. The Green River Police Department was first to respond and contacted the FBI.

On August 26, 2013, another bank robbery occurred at a bank in Afton, Wyoming, where the robber wore a false beard, earbud, and a latex glove.

The Afton Police Department, Lincoln County Sheriff’s Office, and the Wyoming Highway Patrol responded and took Sheriff into custody twenty miles south of Afton a short time later.

Inside his vehicle, police found earbuds, latex gloves, a false beard, a police scanner, an Apple iPhone wrapped in tinfoil, the bank robbery demand note, as well as about $8,000 in cash from the bank.

Sheriff was categorized as an armed career criminal based on his conviction for ten prior bank robberies between 1982 and 1989. Sheriff was released from his 1989 prison sentence on 2008 and successfully completed supervised release in 2011.

The Green River Police Department was an indispensable partner with the FBI, working hand in hand throughout the three-year investigation to bring Sheriff to justice.

The FBI utilized resources from the FBI Laboratory, the FBI Denver Division, FBI Salt Lake City Division, and the FBI Milwaukee Division. A successful prosecution would not have been possible without the support of the Afton Police Department, the Lincoln County Sheriff’s Office, and the Wyoming Department of Corrections.
