Investigators say Graham was one of three suspects who entered the high-end story on Old Georgetown Road on Dec. 13 and stole $60,000 worth of jewelry at gunpoint.

Police said the surveillance video they released on Dec. 17 following the robbery led to a number of tips identifying Graham as the gunman.

They are still trying to identify the masked suspects who accompanied Graham during the robbery.
