Reports are now surfacing that little Madeleine McCann has died from an overdose of sleeping pills.

French investigative reporter Guilhem Battut, who also worked on the Princess Diana case, said a report outlining how the four-year-old met her death was already with Portuguese prosecutors.

The newspaper France Soir said it contains scientific analysis of the bodily fluids found in the boot of the car hired by Kate and Gerry McCann which "prove that the little girl had ingested medicines, without doubt sleeping pills, in large quantities".

However, British forensic experts expressed severe doubts about the claim. They said the fluid was only a partial match to Madeleine's DNA and the sample was not strong enough to determine the presence of drugs. Even so, the report will come as a grave blow to the McCanns.

It supports theories published in Portugal that Mrs. McCann was involved in Madeleine's death and her husband helped her dispose of their daughter's body.
