Two brothers of the Lippens family have been accused of child abuse from several sources. Will these accusations ever be thoroughly investigated is yet to be determined.
Did X1 witness, compelled to murder, Katrien De Cuyper at Castle Kattenhof in 1991? We won't know for sure unless the investigation is reopened with the knowledge of X1's testimony is still credible even though minor details have differed. With all the connections between the people accused by X1 are put into view, it enhances the case rather than discredit it.
X1 apparently witnessed Carine "Clo" Dellaert's murder, at which she saw similar people involved in murders of other girls. The life of Carine is briefly examined and X1's testimony is determined to have been credible.
“You don’t believe that they [Haemers gang] did these robberies with the four or five of them? To pull off something like that you need an army of accomplices! Well-placed accomplices." (December 1993, quote of Etienne Delhuvenne)
"No one will believe you Regina [Louf/X1]. And those who do will be destroyed. I am protected by powerful people. (Antoine “Tony” Van Den Bogaert, as quoted in Regina Louf’s autobiography)
"Marc had accurately sensed that he would benefit from continuing to see Nihoul, because of his connections and those of his wife, the lawyer[Annie Bouty]." (PV 2739, October 9, 1996, testimony of Michelle Martin, ex-wife of Marc Dutroux)
"I met Nihoul in a restaurant in Brussels. 'I am the Monster of Belgium,' he roared at me by way of greeting. He is confident he will never come to trial and that the evidence against him will never be heard by any jury. During the course of our meal he, apparently playfully, grabbed me, tickling, and finally pulled me over on to him in the restaurant booth until I had to appeal to my colleagues for rescue." (May 5, 2002, Olenka Frenkiel for The Guardian, 'Belgium's silent heart of darkness')
All roads in the Dutroux affair, lead to Jean-Michel Nihoul.
