2-Year-Old Boy Found Alone in Diaper in Rock Hill

   ROCK HILL, S.C. (AP) _ Police say a 2-year-old boy was found walking in a Rock Hill neighborhood in only his diaper.
 
   Investigators say it took them about two hours to identify the boy, who walked away from his baby sitter Monday morning.
 
   Police say the boy was not hurt.
 
   Police officers fanned out across the neighborhood trying to find the boy’s caretakers. Authorities say the boy’s grandmother saw his picture and called officers.
