ABC News: Second-grade teacher Elaine Brown was put on paid leave after warning the local sheriff that one of her seven-year-old students is violent. "This child has a history of choking, kicking in the groin, and pushing on monkey bars to fall down," said Terri Worthington-Pack, a parent at Oakhurst Elementary School who volunteers on the playground. Brown said she saw her student hit another second grader at lunchtime.
