Robert (Bobby) Munson
Bobby "Elvis" Munson serves as SAMCRO's treasurer.
How did he earn such a nickname? Because he does Elvis impersonations in Lake Tahoe, of course. The character is a demolition and explosives expert.
Munson was jailed for the murder of Brenan Hefner, after a woman that lived in the building witnessed the murder and told the cops. However, Jax threatened the witness into leaving California and the case Bobby was based solely on that testimony.
