A Mexico, Missouri gym teacher is facing charges of Abuse or Neglect of a Child and Endangering the Welfare of a Child after striking a nine-year-old boy with a large bag of balls.

According to court documents, 48-year-old Katrina Dukes, a teacher at Eugene Field Elementary School in Mexico, was picking up balls from the gym on April 27. The alleged victim was sitting in what is known as the "penalty box." Surveillance video shows Dukes about halfway through picking up the balls when she runs toward the victim with the bag of balls in her right hand.

When she reaches the victim, Dukes allegedly swings the bag in a downward motion. After that, she swings a second time with a "backhand motion," striking the victim.

According to the documents, the child showed signs of a large continuous bruise on his upper leg. A student interviewed by police said the teacher struck the boy with the bag "so hard."
