WILLIAMS, Ariz. (AP) - Authorities say a 10-year-old child was fatally injured in a two-vehicle wreck on Interstate 40 in northern Arizona.

Trooper Kameron Lee says the child was fatally injured when an eastbound SUV towing a trailer collided with a tractor-trailer rig and rolled off the highway about 10 miles east of Williams early Friday morning.

Lee says the Department of Public Safety's investigation continues but that preliminary information indicates that the collision occurred when big rig rear-ended the SUV.

Lee also says additional information about the victim and circumstances of the wreck are not immediately available.

The wreck closed a four-mile stretch of eastbound Interstate 40 for several hours Friday morning.
