2 December 1948 – Sam Shockley
He was originally jailed for life as a result of robbery and kidnap. However he was classed as unstable and transferred from Leavenworth to Alcatraz where he tried to escape twice.
Shockley played a key part in the Battle of Alcatraz, which failed descending into a bloody shoot-out, which lasted two days and killed five men. He pleaded insanity to no avail and was ultimately sent to the gas chamber aged 38.
