The note Victor Tamar Coppins handed the bank teller July 30, 2007, stated "I got a gun . . . Don't speak."
Moments after being handed $749 in an envelope, Coppins, 41, ran from the Victory Drive Wachovia Bank.
Sitting Thursday in a blue jail shirt and pants, Coppins admitted to the bank robbery before U.S. District Court Judge Clay Land. He faces a maximum of 20 years in prison.
Authorities were led to Coppins after his picture was shown on local media, said Assistant U.S. Attorney Brendan Flanagan. Relatives of his ex-wife helped identify him.
His right thumb print, left on the note he handed the bank employee, also linked him to the crime.
Coppins chose to plead "cold," or without a written agreement between his attorney and prosecutors as to his recommended prison sentence.
Coppins will be sentenced after a pre-sentence investigation is completed. He's agreed to repay the money he took, which was never found.
