Suspicion over Bouhouche having been involved in the still unsolved 28 murders committed 1982-85 by the mysterious Brabant killers grew as details emerged of his psychopathic behavior and bizarre schemes . The most remarkable revelation was that Bouhouche had been leader of a complex extortion plot for blowing up gas mains just outside the shops of a supermarket chain ( the Brabant killers ' massacres had mainly been of shoppers in a chain of just such stores ) . Bouhouche had thought it up in the late seventies and involved several friends in concrete pre-preparations , which progressed to the construction of a secret escape tunnel from a building where the ransom payment was to be made . Another connection was that Mendez became so concerned that guns had passed through his hands and then been used in the Brabant killers crimes , that he had repeatedly contacted police for reassurance . Bouhouche 's physical size and facial features not fitting any description compiled from early unmasked encounters with the three main ( possibly only ) members of the Brabant killers gang weighs against his active participation , especially in 1985
