A female relative has accused George Zimmerman, the killer of the unarmed black teenager Trayvon Martin, of molesting her over a 10-year period. The unnamed woman says the abuse began when she was six years old and Zimmerman was eight, lasting until she was 16. The woman says she came forward to prosecutors early on in their probe of Zimmerman to disclose her knowledge of his family’s bias against African Americans. On newly released recordings, the woman said she was concerned Zimmerman had killed Martin because Martin was black.

Witness: “I was afraid that [Zimmerman] may have done something because the kid was black, because growing up, they’ve always made — him and his family have always made statements that they don’t like black people if they don’t act like white people. They like black people if they act white. And other than that, they talk a lot of — a lot of bad things about black people.”
