Trayvon Martin, the unarmed black teenager who was shot and killed by a neighborhood vigilante in Florida, was on the phone with his girlfriend moments before the incident, new phone records confirm. The 16-year-old girl, whose name has not been released, told the Martin family’s attorney that Trayvon knew he was being watched, “so he put his hoodie on.” She continued: “I told him to run but he said he was not going to run.” The girl then heard the man—George Zimmerman—approach Trayvon before the line went dead. No charges have been filed, but the case is being referred to a Florida grand jury. On the 911 call with police, Zimmerman told the dispatcher that he was following Martin, and the dispatcher told him “you don’t need to do that.” Zimmerman has said he acted in self-defense.
