Healey died at Providence St. Joseph Medical Center Dec. 21 and his family is only now making the news public, the Los Angeles Times reported Monday.
His first bad guy role was opposite Johnny Mack Brown in 1948's "Hidden Danger." After that, he became a regular in similar films starring Brown, Whip Wilson and Jimmy Wakely, the Times said.
Boyd Magers of Western Clippings called Healey "one of the best, most recognizable and most frequently seen heavies in the waning days of the B-western and the burgeoning days of the TV western."
His regular TV appearances included stints on "The Adventures of Wild Bill Hickok," "Range Rider," "Bonanza," "Maverick" and "Rawhide." He played Doc Holliday for a year in the late 1950s on "The Life and Legend of Wyatt Earp."
Healey wrote screenplays for a number of the B-Westerns, including 1951's "Colorado Ambush," in which he also appeared, the Times said.
He was honored with the Golden Boot Award from the Motion Picture & Television Fund in 2000 for his work in westerns.
He was divorced four times and is survived by two daughters, a grandson and a great-grandson.
