Travyon Martin

Trayvon Martin walked into a 7-Eleven in Sanford, Florida, grabbing a bag of Skittles and a can of Arizona iced tea. The hood from his dark gray sweatshirt over his head, he walked up to the counter, reached deep into his pants' pockets, paid the clerk, then walked out.

This seemingly mundane act, captured on a surveillance video, would be the last image the 17-year-old's loved ones would have of him alive.

While questions still remain, what happened next to Martin on the night of February 26 became clearer on Thursday with the release of scores of pages of investigative and medical examiner's reports, in addition to new images of Martin's shooter and the 7-Eleven video.

Martin didn't live in Sanford, a central Florida city of about 53,000 people. Yet by that winter night, he'd been there for seven days, after being suspended for the third time from Dr. Michael M. Krop High School in Miami, in this instance, for 10 days after drug residue was found in his backpack, according to records obtained by the Miami Herald.
