At first, the Brabant-Nivelles Killers-Gang may seem like a pretty normal rural bandit outfit; they stole weapons and supplies and aimed their attacks at supermarkets. They seemed to care little about material things: If they took cash at all, the sums were in the lower-five-figure ballpark at best -- not nearly enough to justify the excessive planning and violence they used. In fact, their main interest was a very different one: mayhem. They made a point of torturing and killing victims whenever they could, claiming 28 lives and wounding dozens during their spree. One of their very first heists targeted a tavern, the owner of which they ruthlessly tortured and killed. Their loot: coffee and wine. Yep, these were the sort of people who would happily shoot a child in the face, which they of course also did, because sometimes the world is a strap-on in the devil's asshole.
I didn't expect to use this image this early in the game, but here you go.
From what investigators have been able to piece together, the Brabant Killers consisted of three permanent members and a bunch of assorted henchmen. In a pretty transparent effort to lure Batman into taking the case, the authorities dubbed the main members the Giant, the Killer, and the Old Man.
