The parents of two Poudre School District students are suing the district and four administrators for employing a school bus paraprofessional with a known criminal history of child abuse who was sent to prison for assaulting children on the buses. The students, who are identified in the lawsuit only by their initials, were hit, kicked, pinched, poked, slapped and cursed at by Tyler Zanella, who was employed during the 2022-23 school year.
