Reports: Madeleine's parents prime suspects

LONDON, England (CNN) -- The parents of missing British girl Madeleine McCann have been named as prime suspects in the disappearance of their daughter, according to media reports.

Eight months after four-year-old Madeleine vanished from the Portuguese resort of Praia da Luz, it has emerged that Portuguese detectives still believe they may have been responsible for their daughter's death.

Portuguese newspaper Correio da Manha says an interim report claiming the couple accidentally killed Madeleine is to be handed into the public prosecutor.

The newspaper also says the couple could be charged with perjury and wasting police time.

However, the police file is also reported to include the theory that Madeleine may have been abducted.

The interim report is understood to be part of the prosecution's bid to extend the suspect status of both the McCanns and Robert Murat, the only other suspect.

Murat was named a suspect on May 14, and Portuguese police must charge him, release him or extend his status by January 14.

Madeleine's disappearance on May 3 made headlines around the world. Her parents Kate and Gerry McCann say she disappeared from their hotel room at the resort while they dined in a nearby restaurant.

They embarked on a high-profile campaign to highlight their daughter's plight, traveling throughout Europe and Africa. A Web site, Find Madeleine, has raised more than a million pounds ($2 million) to help the search.

The parents, who are devout Catholics, met with the Pope and enlisted the support of celebrities and sports stars including soccer player David Beckham and author J.K. Rowling.

In spite of a huge media focus on the disappearance and a number of suspected sightings in Europe and North Africa, no arrests have been made in connection with the case. However, massive media interest has resulted in a tidal wave of speculation in the British and Portuguese press.

Media coverage of the case, which has rarely left the front pages of British newspapers, grew further in September when the McCanns, both 39, were named as suspects by Portuguese investigators. Both have strongly denied any involvement in their daughter's disappearance. E-mail to a friend
