Kelly was an American gangster who became notorious for committing a series of robberies and killings during the prohibition era.

Urschel but was eventually caught and sentenced to life in prison, where he died in 1954. What less violent nickname did Kelly reportedly earn during his time at Alcatraz? Discuss
