According to police, the driver lost control of the vehicle, left the roadway, struck the ditch, and overturned.
The crash ejected the child from the vehicle, resulting in fatal injuries. They were transported by the Monroe Community Ambulance to Beaumont Hospital in Trenton, where they succumbed to their injuries.
