Lewisville man sentenced to federal prison for string of bank robberies

SHERMAN, Texas - A Lewisville man has been sentenced to federal prison for bank robbery in the Eastern District of Texas, announced Acting U.S. Attorney Jay R. Combs.

Kyung Heo, 31, pleaded guilty to bank robbery and was sentenced to 71 months in federal prison by U.S. District Judge Amos L. Mazzant, III on September 30, 2025.

According to information presented in court, on November 18, 2022, Heo entered the Comerica Bank on State Highway 121 in Lewisville and approached the bank manager asking if the bank could process a cashier's check. When told the bank could only process cashier's checks for clients, Heo produced a handgun and pointed it at the manager. Heo pushed the manager out of the way, pointed the handgun at the tellers, and demanded they give him money. After taking the money, Heo exited the bank and departed the area on foot.

On April 6, 2023, Heo entered the American National Bank on Cross Timbers Road in Flower Mound, approached a teller station, pulled out a handgun, jumped over the counter, and instructed the tellers to empty their cash drawers. Heo then placed the money in a plastic bag before departing the area on foot. Shortly after the robbery, officers searched the area and located a plastic bag containing $18,943 cash in a nearby drainage ditch. American National Bank reported an additional loss of $10,208 for a total amount of loss is $29,151. An analysis of surveillance videos from the two robberies was also used to link Heo to the June 6, 2023, robbery of the Citizen's National Bank in Weatherford. Heo was convicted in the Northern District of Texas for that robbery and sentenced to 57 months in federal prison. His Eastern District of Texas sentence will run concurrently to the sentence for the Weatherford bank robbery.

This case was investigated by the FBI, Lewisville Police Department, and the Flower Mound Police Department. This case was prosecuted by Assistant U.S. Attorney Matthew T. Johnson.
