About Aaron Mitchell

Aaron C. Mitchell was a murderer, convicted of the February 15, 1963, killing of Sacramento police officer Arnold Gamble, who was responding to a robbery committed by Mitchell. He was sentenced to death, and was executed in the gas chamber. Mitchell, who was from Alabama, had a lengthy criminal record that spanned 20 years. Mitchell was the last inmate to be executed involuntarily before the U.S. Supreme Court's ruling in Furman v. Georgia in 1972, which invalided all existing death penalty statutes at the time.
