A few years earlier, Danny and Derek's father, Firefighter Dennis Vinyard, was murdered by black drug dealers after being sent on a call to fight a fire in a drug den. In a television interview conducted after Dennis's death, Derek erupted in a long racist tirade. Shortly thereafter, Cameron Alexander and Derek formed a white supremacist gang called the Disciples of Christ (D. O. C. ). As a skilled basketball player, Derek was reluctantly dragged into a basketball game against several members of the Crips in which the prize was control of the recreation center basketball courts. After winning with his friends, Derek led a large gang of skinheads to attack a supermarket owned by a Korean that employed African-American and Latino workers. Derek's mother Doris invited Murray, whom she was dating, home for dinner, which turned into a full-blown argument between Derek and Murray, with Derek assaulting their sister Davina, Murray leaving, and Doris kicking Derek out. That night, Danny heard people attempting to steal Derek's truck, Derek shot and killed one of the thieves and curb stomped another, before being arrested. He was sentenced to three years in the California Institution for Men for voluntary manslaughter.
