The mother of the boy struck by a car in Chippewa Township is facing child endangerment charges.  Chavaun Bolton of White Township was charged Thursday after allowing the six-year-old boy and his eleven-year-old sister to walk across a four-lane highway unsupervised Tuesday morning.  The two were trying to cross Route 51 when the boy ran into the road and was hit.  The six-year-old is expected to recover from his injuries.
