Koos Reuvers was the right hand of Johan Verhoek so I would say they are at the top in the underworld they raided his camp in Lith last week but I think he lives near Marbella most of the time. The other families alle have big networks so difficult to say how strong they are. Another family are the Pfaffs yvon Pfaff a Belgian was killed some years ago he was from Ochten not far from Oss. They are related to Jean-Marie Pfaff.
