LOUISVILLE — A mother of a girl with special needs says her daughter was left unsupervised at the school and was raped by a male student. The Courier Journal reported Thursday that the mother is now suing officials at Ballard High School in Louisville, saying they left her daughter, who has “significant intellectual impairment,” unattended. The lawsuit says school workers were supposed to escort her daughter from the school bus to her classroom, but failed to do so one day in February 2018. It says a male student then took her to an empty area and raped her. It says the school later said the girl had been “attacked” and couldn’t be monitored at all times. Jefferson County Public Schools spokeswoman Jennifer Brislin says the district doesn’t comment on pending legitimation.
