(CBS/AP) GREENVILLE, Pa. - Authorities issued an Amber Alert for a 10-year-old western Pennsylvania boy, and summoned dogs and a helicopter to search for him, all because the boy's ailing grandfather was unable to clearly explain he had taken the child to a friend's house days before.Fire Chief Dave King tells the Sharon Herald that dozens of volunteers had begun searching Hempfield Township, near Greenville, about 5 p.m. Sunday after some relatives couldn't find the boy. Greenville is about 65 miles north of Pittsburgh.
Emergency officials aren't identifying the boy or the grandfather with whom he lives, but say the man suffered an unspecified medical problem that made him unable to communicate sometime after taking the boy to the friend's house on Thursday.
Authorities found the boy Sunday evening. He's in the custody of Mercer County child welfare workers.
