Report: McCann Detectives Seek Pedophile Gang in Spain, Search Abandoned Crematorium with Recent Activity in Canary Islands

New evidence has private investigators questioning whether Madeleine McCann may have been kidnapped by a Spanish pedophile gang, the London Daily Mail reported Monday.

The evidence comes on the heels of an abduction of a 5-year-old gypsy girl Sunday night while playing in a park on Portugal's southeast coast, the same area where the McCann investigation began, the Daily Mail reported.

The Metedo 3 agency, the independent firm hired by the McCanns, is focusing on this area following leads from southeast cities like Valencia and Alicante. Portuguese newspaper Diario de Noticias revealed these two areas are known to include various gangs of child sex abusers that have links with pedophiles in various other countries such as Belgium.

Kate and Gerry McCann were seen in the Spanish city of Huelva at least once following the belief their daughter's kidnapper may have traveled with her through that town, according to the Daily Mail.

Local media have brought allegations against the McCanns stating the true intent of their trip to Huelva may have been to dispose of Madeleine's body. However, no evidence has been brought to support these claims.

Huelva borders Portugal on the country's southeast border. There is no border patrol between these two countries and Spanish authorities were not notified of her disappearance until the morning after. It took 12 hours before they were provided with a picture and description of the child giving the kidnapper a large window of time to cross the border without being noticed.

Metedo 3 director Francisco Marco has stated publicly he knows where Madeleine is and that he would have her returned to her parents by Christmas. The McCann’s are paying Metedo 3 $74,374 a month but they will not renew the contract when it runs out in March, the Mail reported.

Police are also focusing on the Canary Islands paying close attention to a pet crematorium after a former worker Marcos Cabrera, 37, attempted to abduct a 10-year-old girl in the area. Forensic teams have begun searching the incinerator at the crematorium for traces of children's remains, the Mail reported. The crematorium has been closed for four years but some activity is believed to have taken place there within the last two months.

Madeleine, now 4 years old, vanished on May 3, 2007 while her family was on vacation in Portugal. Her parents left her and her younger twin siblings unsupervised in a hotel room while they were having dinner some 400 feet away.
