On Feb. 26, 2012, Trayvon, 17, was shot and killed in Sanford, Fla., as he was returning to a gated community. His family says he was followed and then killed because the gunman, George Zimmerman, deemed him “suspicious” because the teen was black and wearing a hoodie. Zimmerman said he shot Trayvon in self-defense. The debate caught the attention of the nation. A memorial for Trayvon sits outside the scene of the encounter.
