A Fort Campbell soldier has been charged with aggravated child abuse after the child was taken to Vanderbilt University Children's Hospital with head injuries.

Clarksville police say 20-year-old Joshua Ryan Starner of Clarksville, Tenn., was arrested Saturday. His bond was set at $1 million. Starner is listed as a specialist corporal in the Army. He did not have an attorney listed in jail records on Sunday.

The Clarksville Leaf-Chronicle says the child's mother left the boy at home for two hours while going to the store on Saturday.

When the mother returned from the store, she found the boy unresponsive. The mother called 911 and the boy was taken to Vanderbilt University Children's Hospital.

Police say medical personnel at Vanderbilt advised that the child has severe forehead trauma and other injuries. The child remained in critical condition on Sunday.
