The daughter of a Belgian priest has confessed to helping him kill four close relatives, including her two brothers, dismember the bodies, and dump them in plastic bags outside a slaughterhouse, a Belgian newspaper said yesterday.

In testimony to police on Thursday, 39-year-old Agnes Pandy said she and her father either shot or battered their victims to death with a sledgehammer, Dimanche Matin said.

They then used acid baths to dissolve some of the corpses. Others were hacked up, put in plastic sacks and dumped outside an abattoir in the Anderlecht district of Brussels, it said.

''The accused (Agnes) said the bodies would not be found because they had been cut into pieces and some parts dissolved in acid. Others were put in plastic bags and deposited, notably near the Anderlecht abattoir.''

The four were her brothers Daniel and Zoltan, her stepmother Edith Fintor, and Fintor's daughter Andrea.

There was no immediate comment from the public prosecutor's office, which on Saturday confirmed that Pandy had confessed to murdering her own mother, Ilona Sores, and to helping in the four other murders.

It was not immediately clear whether Pandy's confession would result in the number of murder charges against her father, Protestant clergyman Andras Pandy, being cut from six to five.

Hungarian-born Andras Pandy, 70, was arrested last month and charged with murdering his two former wives and four of his eight children. Agnes Pandy has also been charged with murder and aiding in murder.

A spokeswoman for the public prosecutor said at the weekend: ''It was she alone (Agnes Pandy) who killed her mother, and she participated with her father in murdering four other members of the family. The motive for these killings has yet to be determined.''

According to Dimanche Matin, Belgium's only Sunday newspaper, Agnes Pandy has said all the murders took place in Pandy's house in Quai de l'Industrie, in the poor Brussels quarter of Molenbeek, between 1986 and 1989.

It was in this house that police found human bones and teeth belonging to four people, as well as slabs of frozen meat of uncertain origin. Initial DNA tests on the material has indicated it came from four bodies, none of which matched the known DNA samples of the Pandy family, media reports have said.

This has heightened media speculation that the death toll in Belgium's latest macabre murder saga could rise to at least 10, with the suspicion Pandy enticed women to Brussels from Hungary through newspaper advertisements offering a trial marriage.

Andras Pandy has lived in Belgium for some 30 years since fleeing the 1956 Hungarian uprising. But he made frequent trips back to Hungary, and found his second wife through an advertisement in a local newspaper there.

There has as yet been no link made between the Pandy case and the discovery in March and April this year, in the southern city of Mons, of the surgically-severed limbs of four women, deposited in plastic bin bags in various locations with suggestive names, such as Worry Street and Hate Street. - Reuters
