Cops Follow Tip On Missing British Toddler

Police investigating the disappearance of Madeleine McCann said they may use sniffer dogs to search a rural area where an anonymous tip said the 4-year-old British girl could be buried.

A Dutch newspaper reported Wednesday it had given police an anonymous letter it received with a map showing a location in southern Portugal where Madeleine might be found.

Detectives said the tip was one of the leads they were following in the investigation but declined to elaborate.

The location shown on the map is scrubland about 10 miles from where the girl vanished while on vacation with her family more than a month ago,

Madeleine disappeared May 3 from a hotel in Praia da Luz, a resort town in Portugal's Algarve region. Her parents left her and her 2-year-old twin siblings alone in their hotel room while they dined at a nearby restaurant.

Since then, the couple has launched an international campaign to find the girl, enlisting the aid of celebrities including soccer star David Beckham and J.K. Rowling, author of the Harry Potter series.

Kate and Gerry McCann have also traveled to Spain, Germany, the Netherlands and Morocco to plead for help in finding their daughter.
