Authorities say Tonya Thomas, 33, shot and killed her four children before killing herself on May 15, 2012 in Port St. John, Fla. The shooting happened about 15 miles west of Cape Canaveral in an area known as the "Space Coast" because it is the home of NASA's Kennedy Space Center.
Deputies identified the children as Pebbles Johnson, 17; Jaxs Johnson, 15; Jazzlyn Johnson, 13; and Joel Johnson, 12.
