Oscar Juliuss Grant III, (February 27, 1986 – January 1, 2009), lived in Hayward, California. Grant had worked as a butcher at Farmer Joe's Marketplace in Oakland's Dimond District after previous jobs at several Kentucky Fried Chicken outlets. He attended both San Lorenzo and Mount Eden High Schools in Hayward until the 10th grade and eventually earned his GED.
Grant served two state prison terms for various felonies including a conviction for drug dealing. In 2007 he was sentenced to 16 months in state prison for fleeing "from a traffic stop while armed with a loaded pistol". During that incident, near his Hayward home, San Leandro police shot him with a Taser to subdue him after he threw the pistol into the air and ran. The arresting officers testified that even after being Tased, Grant "continued to resist efforts of the officers to handcuff him".
Grant was released from prison on September 23, 2008, and according to the attorney for Grant's family, John Burris, "had been doing well in recent months". Burris also stated that the criminal conviction and Tasing was "irrelevant to the BART shooting because Mehserle wasn't aware of it when he opened fire".
In the motion for bail, Mehserle's attorney, Michael Rains, stated that toxicology testing of Grant's blood revealed the presence of alcohol (0.02%) and Fentanyl, a strong narcotic pain reliever. The coroner's bureau said the pathologist's autopsy protocol would be finalized in March 2009.
Grant's funeral was held at the Palma Ceia Baptist Church in Hayward on January 7, 2009. He is survived by his mother, sister, four-year-old daughter, and girlfriend (his daughter's mother), who are the claimants in a wrongful death claim against BART.
