St. Mary’s Law School professor Bill Piatt and his son Bob Piatt, a San Antonio attorney, completed a San Francisco swim that has claimed the lives of many a prisoner.

Of the 36 inmates who staged 14 escape attempts from Alcatraz Island during the time it served as a federal penitentiary, 23 were captured, six were shot and killed, two drowned and five are still listed as missing. But on Sept. 30, both Piatts safely completed the 1.25-mile swim from Alcatraz Island to San Francisco.
