Oscar Grant III was a 22-year-old black man who was killed in the early morning hours of New Year's Day 2009 by BART Police Officer Johannes Mehserle in Oakland, California. Responding to reports of a fight on a crowded Bay Area Rapid Transit train returning from San Francisco, BART Police officers detained Grant and several other passengers on the platform at the Fruitvale BART Station. BART officer Anthony Pirone kneed Grant in the head and forced Grant to lie face down on the platform. Officer Johannes Mehserle drew his pistol and shot Grant. Grant was rushed to Highland Hospital in Oakland and pronounced dead later that day. The events were captured on bystanders' mobile phones. Owners would then upload the footage to YouTube. Both protests and riots took place in the following days.
Some of the other passengers on the train, along with Grant's girlfriend Sophina, were able to break up the fight. Shortly afterward, the train conductor announced to the passengers that the police had been contacted and were on their way to the station at which they were stopped. As the passengers began to exit the train, Grant and his girlfriend saw the police walking towards them and split up. As they got closer to the train, police started to pick out people they believed to have been involved in the fight. Pirone walked up to two black men and ripped the jacket off one. Pirone threw three people against the wall and then turned to the train, yelling for everyone involved in the fight to exit the train and come to him. Everyone remained on the train, so Pirone walked into the train to see if there was anyone who looked as if they were involved in the fight. Pirone saw Grant and removed him.
