Now authorities are telling George Zimmerman’s side of the story. Zimmerman told police that Trayvon Martin approached him from the rear and punched him in the nose before repeatedly slamming his head into the sidewalk. Around this time witnesses heard screams for help, and police say that evidence suggests those screams came from Zimmerman, not Martin. At least one witness corroborated this version of events, and Zimmerman had various injuries when police arrived on the scene. It has also emerged that Trayvon had been suspended from his school after officials caught him with an empty baggie that contained marijuana residue.
