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.
