News of the search for the remains of a possible fourth victim is given in Friday’s editions of the dailies ‘Gazet van Antwerpen’ and ‘Het Belang van Limburg’.
Ronald Janssen has already confessed to the first three murders.
During questioning he also said that several years ago he drove around with a woman’s body in his car.
According to press reports, Ronald Janssen claimed that he had dumped the body somewhere in the eastern part of Liège province, not far from the German border.
However, he couldn’t remember exactly where.
Detectives are reported to be keeping an open mind and plan to dig up Ronald Janssen’s garden to see if any human remains are buried there.
The judicial authorities in Hasselt have so far refused to comment.
