Mike DeStefano of "Last Comic Standing" dies of heart attack

(CBS) - He was known for his appearance on NBC's "Last Comic Standing" and the sometimes uncomfortable honesty he put into in his shows. He was set to start a one-man show in New York  on Wednesday.

But instead Mike DeStefano died  Sunday night from a heart attack, according to reports.

The Bronx native is probably best known as a finalist from the last season of "Last Comic Standing." He recently wrapped up a series of sold-out shows called "Drugs, Disease and Death: A Comedy."

It was this sort of dark-tinged, self-effacing humor that DeStefano used. He came from a history of deep drug addiction - he began using heroin at the age of 15 according to TV Guide - and never entered the world of comedy until the death of his wife.

The producer of DeStefano's recent show and long-time supporter posted  a one-word message on Twitter-  simply: "devastated."
