Maddy Hollanders was last seen in East Flanders, Belgium, in the company of serial killer Claudy Pierret. Pierret, a sadistic killer, remains the prime suspect in her disappearance. Maddy was his stepsister.
Pierret was convicted of two murders of women who were found badly mutilated. He left their bodies in areas in Belgium that were familiar to him. I'll skip the grisly details, but there is nothing in the case of Het Heulmeisje that points to Pierret or Maddy Hollanders ~ Maddy remains missing and her body has never been found.
