About 7 p.m. Zimmerman, a 28-year-old unofficial neighborhood-watch man, called 911 to report a "suspicious person," later reported to be Trayvon, in a gated community, Retreat at Twin Lakes, in Sanford, Fla. Despite instructions from the dispatcher, Zimmerman pursued him. Zimmerman alleges that after an exchange of words, Trayvon punched him in the nose, pinned him to the ground and began slamming his head into the sidewalk. About 7:25 p.m. Trayvon was shot once in the chest and killed. At the time of his death, the unarmed teen, who was on his way back to his dad's home after a trip to a convenience store, was carrying a small amount of cash, a bag of Skittles and a can of iced tea. He was wearing a hoodie.
