The attorney for George Zimmerman, the man who shot and killed 17-year-old Trayvon Martin last month, said Monday that Martin initiated the confrontation, beating his client so badly he suffered a broken nose and injuries to the back of his head.

Physical evidence, including a grass stain on the back of his shirt, showed there was a scuffle, lawyer Craig Sonner told ABC News. “When the evidence comes out, it will show that George Zimmerman was acting in self-defense in this case,” Sonner said. “It’s not a racial issue.”
