A Pampa man found guilty of a bank robbery has been sentenced.

Fifty-one year-old Billy Michael Grimes has been sentenced to 8 years in federal prison and ordered to pay $2,800 in restitution.

Grimes committed the armed robbery of the Amarillo Community Federal Credit Union in Pampa on September 15th, 2012.

He reportedly approached a teller and said that he needed to make a withdrawal. When the teller advised him that he would need to complete a withdrawal slip, he brandished a gun and told her that he did not need a withdrawal slip.

Grimes was identified by law enforcement a short time after the robbery. Officers found him with a donut bag, which he had purchased just moments after the incident using one of the bills from the robbery.

The investigation was conducted by the Federal Bureau of Investigation and the U.S. Attorney’s Office in Amarillo.
