A Lewisville man has been sentenced to federal prison for his involvement in multiple bank robberies across Texas, according to an announcement by Acting U.S. Attorney Jay R. Combs of the Eastern District of Texas.
Kyung Heo, 31, pleaded guilty to bank robbery and received a sentence of 71 months in federal prison from U.S. District Judge Amos L. Mazzant, III on September 30, 2025.
Court documents show that on November 18, 2022, Heo entered the Comerica Bank on State Highway 121 in Lewisville and asked the bank manager if they could process a cashier’s check. After being told this service was only available for clients, Heo produced a handgun and pointed it at the manager. He then pushed the manager aside, threatened tellers with the weapon, and demanded cash before leaving the scene on foot.
On April 6, 2023, Heo robbed another bank—the American National Bank on Cross Timbers Road in Flower Mound—by pulling out a handgun after approaching a teller station. He jumped over the counter and ordered tellers to empty their cash drawers into a plastic bag before fleeing. Officers later found $18,943 in cash discarded in a drainage ditch near the area. The American National Bank reported an additional loss of $10,208 for a total loss of $29,151.
Surveillance footage from these incidents also linked Heo to a June 6, 2023 robbery at Citizen’s National Bank in Weatherford. For that crime—prosecuted in the Northern District of Texas—Heo was sentenced to 57 months in federal prison. His sentence from the Eastern District will run concurrently with his sentence for the Weatherford robbery.
The investigation involved cooperation between the FBI as well as police departments from Lewisville and Flower Mound. Assistant U.S. Attorney Matthew T. Johnson prosecuted the case.
