A few years earlier, Danny and Derek's father, 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 erupts in a long racist tirade. Shortly thereafter, Cameron Alexander and Derek form a white supremacist gang called the Disciples of Christ (D. O. C. ). As a skilled basketball player, Derek is reluctantly dragged into a 3-on-3 game against several members of the Crips in which the prize is control of the recreation center basketball courts. After winning with his friends, Derek leads a large gang of skinheads to attack a supermarket owned by a Korean that included African-American and Latino workers. Derek's mother Doris invites Murray, whom she is dating, home for dinner, which turns into a full-blown argument between Derek and Murray, with Derek assaulting Davina, Murray leaving, and Doris kicking Derek out. That night, as Danny hears people attempting to steal Derek's truck, Derek shoots and kills one of the thieves and curb stomps another, before being arrested. He is sentenced to three years in the California Institution for Men for voluntary manslaughter.
