Involvement in case: Charged with second-degree murder in death of Trayvon Martin.
Background: George Zimmerman was volunteering as a neighborhood watchman in the Sanford subdivision when the shooting occurred. He was attending Seminole State College. He is married to Shellie Zimmerman, who is charged with perjury after saying under oath Zimmerman didn't have funds to post bond. The story has gained national attention as the lack of Zimmerman's arrest sparked outcry. Zimmerman was arrested in 2012 more than a month after Martin's death and is currently at an undisclosed location in Central Florida as he awaits a June 2013 trial.
