Education authorities in the northern Mexico state of Tamaulipas have suspended a teacher and the assistant principal at a junior high school where a student was thrown against a wall by four classmates and later died of his injuries. The Tamaulipas education department says in a statement that the 12-year-old boy died Tuesday after being hospitalized for almost a week. State Education Secretary Diodoro Guerra says the student's Spanish teacher and the assistant principal have been suspended pending an investigation. The boy's parents say witnesses described how four of his classmates grabbed him by each extremity and threw him against a wall several times. His father, Javier Mendez, says the teacher didn't stop the assault even though his son pleaded with her to intervene.
