This undated file photo provided by the Martin family, shows Trayvon Martin snowboarding. Martin was slain in the town of Sanford, Fla., on Feb. 26 in a shooting that has set off a nationwide furor over race and justice. Neighborhood crime-watch captain George Zimmerman claimed self-defense and has not been arrested, though state and federal authorities are still investigating. Since the slaying, a portrait has emerged of Martin as a laid-back young man who loved sports, was extremely close to his father, liked to crack jokes with friends and, according to a lawyer for his family, had never been in trouble with the law.
