Columbus man sentenced to 20 years in prison for armed bank robbery in Whitehall

COLUMBUS – A Columbus man was sentenced today for robbing a bank in Whitehall, pistol-whipping two of the bank’s employees while demanding money, and conspiring with his girlfriend to hide the gun he used in the robbery.


Robert K. Mason, 43, was sentenced to 240 months in prison.


According to court documents, Mason robbed the Huntington Bank at 4550 East Broad Street on Sept. 26, 2018. Mason walked in the bank, lifted his shirt to show that he had a gun, pulled the handgun and ordered customers to the floor. Mason vaulted the counter and demanded money from the tellers, hitting two of them with the gun when he became frustrated at the speed of the employees.


Mason ran out the front door and escaped in a car driven by his girlfriend, Bretta L. Nallen. Whitehall police arrested Mason on Oct. 31, 2018. While he was in custody, he called Nallen and told her to get rid of the gun. Nallen was charged with being an accessory to the crime and evidence tampering. She pleaded guilty to the accessory charge in August 2019.


Mason pleaded guilty in April 2019 to one count of bank robbery, one count of using a firearm during a crime of violence and one count of conspiracy to tamper with evidence.


“Mason is a career criminal who has committed a number of violent offenses,” U.S. Attorney David M. DeVillers said. “That’s exactly the type of offender we prioritize prosecuting in this office. Mason earned his time in federal prison.”


DeVillers, Joseph Deters, Acting Special Agent in Charge, Federal Bureau of Investigation (FBI), Cincinnati Division, Columbus Division of Police Acting Chief Thomas Quinlan and Whitehall Police Chief Mike Crispen announced the sentence imposed today by U.S. District Judge Edmund A. Sargus, Jr.


Assistant United States Attorney S. Courter Shimeall is representing the United States in this case.
