Portuguese investigators will continue the search for missing four-year-old Madeleine McCann after alleged sightings of the little girl turned out to be false reports, Portuguese media said Thursday.

According to the Portuguese daily Diario de Noticias, the police will not give up the search for her body and are prepared to carry out “excavations” if “credible leads” emerge. This latest report is another sign that investigators blame the toddler’s parents for her disappearance.

Policemen believe that Madeleine was “accidentally killed” in her parents’ holiday apartment in Praia da Luz, on the Algarve, and declared Kate and Gerry McCann formal suspects.

Thursday’s report appeared one day after media worldwide published pictures of a blonde girl who looked like Madeleine. The photograph taken by a Spanish tourist on August 31 showed the girl on the back of a Moroccan elderly woman.

But thorough investigations dashed the parents’ hopes of finding Madeleine once again, as five-year-old Bushra Binhisa appeared on the front pages of newspapers worldwide, and not Madeleine.

Despite this latest disappointment, Kate and Gerry McCann said they are not willing to abandon the hunt for their daughter, who mysteriously vanished on May 3 from her bedroom.

Both parents continue to deny any involvement in the disappearance of their daughter and criticized the investigators for trying to divert attention from their incompetence.

Numerous editorials appeared in newspapers since the girl was reported missing, but in the past period most of the articles incriminated the couple. In a comment appeared Thursday in the Spanish El Pais newspaper, the McCanns have been accused of trying distract the public’s attention by creating “new facts in the media” every day.

Meanwhile, the couple hired a private security firm, Control Risk Group (CRG) to carry out a separate search for Madeleine.

Also, the McCanns are preparing to launch another advertising campaign in Portugal, Spain and Morocco. This new campaign would cost about 80,000 pounds and will be financed from donations made to a non-charitable fund set up to find Madeleine.

Well-wishers donated considerable sums of money to the fund, while others left thousands of toys and dolls in the McCann’s home village of Rothley. Now, the toys are going to be sent to two orphanages in Belarus as the McCann’s wished.

As part of an operation dubbed Christmas Child, the orphanages in Zhodina, some 30 kilometres from Minks, the Belarus capital, and Bobrusk, in the south, will receive the toys in the following period.

“It is incredible knowing that this family was thinking of other children whilst they are in such turmoil themselves,” said Jane Simmonds, the regional manager for Samaritan’s Purse.
