Dan White

Daniel James White was an American politician who assassinated San Francisco Mayor George Moscone and Supervisor Harvey Milk, on Monday, November 27, 1978, at City Hall. In a controversial verdict that led to the coining of the legal slang "Twinkie defense", White was convicted of manslaughter rather than murder in the deaths of Milk and Moscone. White served five years of a seven-year prison sentence. Less than two years after his release he returned to San Francisco, where he ultimately committed suicide.
