No, did a search and....."None. Alcatraz had no facilities for capital punishment, and no one was ever sent to the Island with a death sentence. Alcatraz inmates who committed capital offenses while on the Island were tried in federal court, sentenced to death, and transferred to San Quentin State Penitentiary for execution in the gas chamber."
Thank you. So death sentence was only for inmates who committed capital crimes while IN Alcatraz. Interesting.
