Sean's death.

Sean is a member of Nucky's bootlegging operation, serving as an enforcer, after Season 4 and the end of Season 5. He is seen multiple times in the last season.

He was sent by Nucky to retrieve Benjamin Siegel with Arquimedes and Mickey Doyle in "Friendless Child". During the proceeding struggle, Siegel shoots all of his bullets but is able to shoot Sean with his own gun through the mouth. Arquimedes then captures Siegel and leaves Sean's body in an apartment.

He is played by actor Nicholas E. Calhoun.
