Alvin 'Creepy' Karpis

Alvin 'Creepy' Karpis was a notorious American criminal and one of the last public enemies of the Great Depression era. He was known for his involvement in bank robberies and kidnappings and was eventually sentenced to life imprisonment at Alcatraz, where he served 26 years, making him one of the longest-serving inmates at the facility. Karpis's criminal exploits and his time in Alcatraz contributed to the prison's infamous status as a place where only the most dangerous offenders were held.
