NEW YORK — Mark David Chapman, who shot and killed former Beatle John Lennon 32 years ago, was denied parole for a seventh time, New York State's Department of Corrections said on Thursday. Chapman, 57, is serving a prison sentence of 20 years to life for shooting Lennon four times in the back outside the musician's New York City apartment building on Dec. 8, 1980. He pleaded guilty to second-degree murder. Chapman has come up for parole every two years since 2000 and has been turned down each time. “Despite your positive efforts while incarcerated, your release at this time would greatly undermine respect for the law and tend to trivialize the tragic loss of life which you caused as a result of this heinous, unprovoked, violent, cold and calculated crime,” Sally Thompson, the parole board's “deciding board member, wrote to Chapman, according to a department statement. — Reuters
