A 9-year-old autistic boy who misbehaved at school was stuffed into a duffel bag and the drawstring pulled tight, according to his mother, who said she found him wiggling inside as a teacher's aide stood by.

The mother of fourth-grader Christopher Baker said her son called out to her when she walked up to him in the bag Dec. 14. The case has spurred an online petition calling for the firing of school employees responsible.
