From left Jay White, Derrick Williams, Sherri-Lyn Miller, and E.J. “Mix It Up” wear their shirts in memoriam of friend Ronnie “Hennessy” Jackson Jr. where he was shot on 90th Ave. near MacArthur Blvd. in Oakland, Calif. on June 21, 2008. Williams, who was shot in an unrelated incident in 2006, was mentored by Hennessy. Miller has turned her frustrations with the violence in Oakland into her business, as she specializes in producing memorial shirts for the community.
