Authorities say a 7-year-old boy was accidentally shot in a first-grade classroom by another student in Louisiana. Nobody else was wounded. Sheriff Tony Mancuso said the boy was shot a few minutes before 8 a.m. Monday. Police said in a news release that the boy was in surgery. Mancuso says the loaded gun fell out of a first-grader's backpack in the classroom, where a second student picked it up. The sheriff says the gun went off by accident.
