2000: Mark David Chapman is denied parole by the New York State Board of Parole. In 1981, Chapman received a sentence of 20 years to life in prison for the Dec. 8, 1980, murder of John Lennon. Since this first hearing, he has been entitled to a parole hearing once every two years. He has been denied parole eight times by a three-member board since then, most recently in August 2014. He's seen here in a 2011 mugshot.
