(CNN) — Here’s a look at the February 2012 shooting death of 17-year-old Trayvon Martin. Former neighborhood watch captain George Zimmerman was acquitted of the crime in July 2013.
Facts: Trayvon Benjamin Martin, born February 5, 1995, was a 17-year-old African-American high school student who lived in Miami Gardens, Florida, with his mother Sybrina Fulton. In February 2012, Martin was visiting his father Tracy Martin in Sanford, Florida, after receiving a ten-day suspension from Krop Senior High School. The suspension stemmed from the discovery of drug residue in Martin’s book bag.
George Michael Zimmerman, born October 5, 1983, was a part-time student at Seminole State College and a neighborhood watch captain at the Retreat at Twin Lakes gated community in Sanford, Florida, at the time of the shooting. He is the son of Robert and Gladys Zimmerman.
