Marcel Vervloesem

Marcel Vervloesem operated as a Belgian private investigator and activist affiliated with the Morkhoven Workgroup, an NGO dedicated to exposing child exploitation networks across Europe during the 1990s. His investigations targeted the disappearance of Manuel Schadwald, a 12-year-old German boy who vanished in Berlin in 1993, linking cases to broader international child trafficking operations involving figures such as Lothar Glandorf, Robbie Van Der Plancken, and Gerrit-Jan Ulrich. Vervloesem's work uncovered the Apollo Bulletin Board Service, one of the largest online distributors of sadomasochistic child pornography, hosted in Zandvoort, and connected to distribution networks in Amsterdam, Rotterdam, and beyond.¹

Investigation into Manuel Schadwald's Disappearance

In the mid-1990s, Marcel Vervloesem initiated an inquiry into the disappearance of Manuel Schadwald on behalf of the Morkhoven Workgroup, reviewing a 1992 police report from a raid on an underage sex party in the Dutch town of Wallre. The report identified Lothar Glandorf at the event alongside a teenager named Robbie Van Der Plancken, establishing early connections to organized child exploitation rings operating through brothels like Euro Boys and Young Boys in Rotterdam. Vervloesem's team cross-referenced this information with witness testimonies from the Pinocchio Bar in Berlin, where Schadwald was last seen with associates linked to British trafficker Warwick Spinks and the Apollo Bulletin Board Service. This phase of the investigation revealed Schadwald's trafficking route from Berlin to Amsterdam, involving sales to networks tied to Marc Dutroux and the broader International Child Trafficking Network Overview.

By June 1998, Vervloesem located Robbie Van Der Plancken in Amsterdam and conducted a filmed interview with Belgian public broadcaster RTBF, confronting him directly about Manuel Schadwald's fate. During the confrontation, associates observed an onlooker who led them to Zandvoort, identifying Gerrit-Jan Ulrich as the owner of Cube Hardware and administrator of the Apollo Bulletin Board Service. Ulrich provided Vervloesem with encoded disks containing thousands of images and videos depicting violent child abuse, including potential matches to victims like Katrien de Cuyper from the Marc Dutroux. The Morkhoven Workgroup subsequently handed over child pornography materials to Dutch police on July 18, 1998, as reported in De Morgen, prompting raids on related operations such as Gero-Video in Dusseldorf.

Vervloesem collaborated closely with Gina Pardaens-Bernaer, another Morkhoven Workgroup member, in analyzing the Apollo Disks for identifications, including possible links to murders at locations like the castle of Baron Philippe de Caters and the Dutch porn studio X-Kiss. Their efforts exposed intersections with the Elm Guest House scandal and Operation Yewtree-related inquiries, implicating high-profile figures in child abuse cover-ups. The interview segments with Robbie Van Der Plancken appeared in the French documentary ‘Zandvoort, the file of shame - Karl Zero Absolute,’ amplifying public awareness of the Zandvoort discoveries and their ties to the Spartacus Club and Toff's Travel.

Impact on Broader Child Exploitation Exposures

Marcel Vervloesem's revelations from the Apollo Bulletin Board Service connected to the Rolodex Investigation and Odyssey Network, highlighting encrypted distribution methods used by perpetrators in the The Finders cult and Spartacus International. His work prompted international cooperation, including examinations of John David Norman's records and Peter Righton's pedophile information exchange, revealing overlaps with Belgian cases like the Grafton Close Children's Home abuses. Vervloesem faced retaliation, mirroring the murder of Gina Pardaens-Bernaer in November 1998, amid efforts to suppress evidence from the Zandvoort files. The Morkhoven Workgroup retained key witnesses in the Manuel Schadwald case, as noted in De Morgen on September 21, 1998, sustaining pressure on authorities investigating Joris Demmink and Leon Brittan.

The exposure of the Apollo Bulletin Board Service through Vervloesem's persistence led to arrests, including Robbie Van Der Plancken in Italy for shooting Gerrit-Jan Ulrich, and influenced probes into TAG Films and German operations post-1993 raids. Connections extended to Jimmy Savile's network via Walton Hop Disco and Stoke Lodge, with Vervloesem's findings corroborating testimonies from the Marc Dutroux involving Jean-Michel Nihoul and Jean-Michel Nihoul.¹
