Colorado paraprofessional Kiarra Jones arrested for assaulting children with disabilities.

Jones worked as a bus aide to help children with autism and other disabilities travel between school and their homes.

Newly released footage shows Jones punching and stomping a disabled 10-year-old boy.

Three families are now taking action against Jones, claiming they started noticing behavioral changes from their children about 6 months ago.

They also noticed physical injuries including scratches, bruises, a lost tooth, broken toe, black eye, and other bruises.

Jones was arrested on April 4 after surveillance footage showed her hitting a student in the abdomen and mouth.
