Sandra Castrejon filed a negligence lawsuit against her son's 7th grade teacher for leaving her students attended, the Chicago Sun-Times reported. Her junior high school son allegedly broke his right femur on Feb. 22 at Chappell Elementary School while the teacher was absent.
The negligence suit, which seeks more than $50,000 in damages, was filed against Chicago Public Schools and the teacher, who was not named in the article.
The teacher left her classroom unattended for "a long period of time" and a fight erupted, eventually leading to her son's broken leg, Sandra Castrejon claims:
"During the fight, someone pushed [the boy] from behind and he fell to the ground with great force and violence, causing the injuries."
