Bobby "Elvis" Munson (Mark Boone Junior) is SAMCRO's secretary. He does Elvis impersonations in Lake Tahoe. Munson is Jewish. He is a demolition and explosives expert. He was incarcerated for the murder of Brenan Hefner after a woman that lived in the building witnessed the killing and went to the police. He was released a few months after Jax threatened the witness into leaving California and the case against him was based completely on the witness's testimony.

Bobby's father was a mob accountant in Reno, who kept two sets of books for the mob – Bobby apparently learned accounting from his father.
