In August 2006, a 35-year-old man from Kessel identified as Karl V.R., who had been arrested for stalking, was charged with the kidnap and murder of De Cuyper. Police searching his house found child pornography on his computer and a box which contained newspaper clippings of articles about De Cuyper's disappearance and murder and copies of the letters sent to Blik and to her parents in 1992. Furthermore, V.R.'s DNA had been found on the stamp on the envelope of one of the letters. In March 2002, his brother had been sentenced to life imprisonment for the murder of his ex-girlfriend's new boyfriend. V.R. admitted that he wrote the letters but said that they were fabricated and that he only wrote them for publicity. In September 2006, De Cuyper's remains were exhumed for further tests.
