ABC News has obtained a medical report that claims Trayvon Martin shooter George Zimmerman had injuries to his face and head a day after he shot and killed the African-American teenager in Sanford, Florida. The report shows Zimmerman was diagnosed with a “closed fracture” of his nose, black eyes, two cuts on the back of his head and a minor back injury. Zimmerman has insisted he shot Martin in self-defense, but recordings of phone calls from the scene show Zimmerman pursued the unarmed teenager in defiance of a dispatcher’s instructions. Zimmerman was charged with second-degree murder and has been in hiding since making bail last month.
