“He can’t even pass a river in his spare time without quickly checking that there is no body in it.” It is a quip that is often mentioned when it comes to Alain Remue (61). The tireless investigator of the federal police has been at the head of the service since the creation of the Missing Persons Unit in September 1995. About 30,000 disappearance files have since gone through his hands: he searched for Annick Van Uytsel, Julie Van Espen and Dean Verberckmoes – but also for Tanja Groen.
