John Costelloe, 47, whose short role as a gay firefighter 'Johnny Cakes' on the HBO hit 'The Sopranos' that made him famous was found dead of a self-inflicted gunshot wound on 18th December in his Brooklyn apartment.

Costelloe, who was also starring in the off-Broadway production of 'Gang of Seven', seemed a little off in his final show performances, according to the show's playwright.

Family members and friends, including 'Sopranos' co-stars are shocked by his death.
