Seamus O'Brien

Seamus O'Brien seemed destined to be in the horror movie business, since in early childhood he expressed a bizarre infatuation with the unknown and the occult. After a short stint of doing movies (his last being "Bloodsucking Freaks"), O'Brien was stabbed to death when trying to hold a burglar at his apartment on May 14th, 1977. He was 44 years old. - IMdb
