A Fort Worth man accused of robbing a Denison bank and two others in North Texas last year was found guilty in federal court Thursday.

Wayne Alan Watson, 58, of Fort Worth was convicted of three counts of armed bank robbery after a three-day jury trial in the court of U.S. District Judge Marcia A. Crone. Watson faces up to 60 years in prison for the robberies of Texoma Educators Federal Credit Union in Denison on Dece. 19, Altra Federal Credit Union in Tyler on Dec. 1 and City Credit Union in Gainesville on Oct. 16.

“In each of the robberies, Watson displayed a gun and by force, violence, and intimidation robbed employees of the credit unions of currency,” the U.S. Attorney’s Office of the Eastern District of Texas said in an emailed news release Thursday. “Additional robberies linked to Watson in Austin and Wichita Falls which occurred in January of 2018, led to his identification as the serial robber.”

A call seeking comment from Watson’s attorney, John Hunter Smith, was not answered Thursday afternoon and a message could not be left. Law enforcement officials executed a search warrant at Watson’s home in Fort Worth in February and recovered a vehicle and articles of clothing, which he used during the robberies. Watson was indicted by a federal jury in March and prosecuted by Assistant U.S. Attorneys Lesley Davis Brooks and Maureen Smith.

The case was investigated by multiple agencies, including Federal Bureau of Investigation, the Texas Department of Public Safety-Texas Rangers Division, Gainesville Police Department, Tyler Police Department, Denison Police Department, Austin Police Department and the Wichita Falls Police Department.
