Mehserle was convicted in 2010 of shooting Grant on Jan. 1, 2009, after Grant was pulled from the BART train. Mehserle says he didn't mean to shoot Grant, who was unarmed and lying face down on the Fruitvale BART platform when he was killed. Mehserle argued in court that he meant to grab for his Taser, but accidentally pulled out his gun and fired one shot in Grant's back, killing him instantly.
The shooting was recorded by other BART passengers, which was used as evidence in his trial.
A jury acquitted Mehserle of murder, but convicted him of involuntary manslaughter. He served only 10 months of his two-year sentence, and was released last year on good behavior.
