ORLANDO, Fla., July 24 (UPI) -- The grandfather of a missing 2-year-old Florida girl has asked thousands of people through automatic telephone dialing to help find his granddaughter.

In his message, delivered in a system that dialed homes in five central Florida counties, George Anthony urged listeners: "Please help my family and me bring her home for her third birthday."

More calls were planned Thursday, the Orlando Sentinel said.
