Theodore Cole and Ralph Roe attempt to escape from the American federal prison on Alcatraz Island in San Francisco Bay; neither is ever seen again.

Theodore "Ted" Cole (born April 6, 1912) and Ralph Roe (born February 5, 1906) took part in the second documented escape attempt from Alcatraz, in 1937. Although officials were quick to conclude they died in the attempt, their remains were never found and their fate remains unknown, making the incident the first to challenge Alcatraz's reputation as an "escape-proof" prison.
