High Quality Content by WIKIPEDIA articles! Daniel James "Dan" White (September 2, 1946 – October 21, 1985) was a San Francisco supervisor 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. Less than two years after serving a sentence of five years, White returned to San Francisco and committed suicide. San Francisco Weekly has referred to White as "perhaps the most hated man in San Francisco`s history."
