Behind the friendly face of a truck driver lies the most gruesome child murderer in our history. The Belgian Michel Stokx killed at least three children, for which child murders he was eventually convicted, but there were probably many more; he is also still the main suspect in the disappearance case of Nathalie Geijsbregts. The man may have taken secrets about dozens of other disappearances with him to his grave. The Stokx case is extensively examined, including simulated reconstruction images.
