Day of Wrath against the Zug MafiaIn the disguise of a police officer (his uniform homemade), killed 14 members of a regional parliament in Zug, Switzerland. Detonated a grenade, then shot himself. His principal target, Robert Bisig, was not injured.
Used a 5.6mm Sturmgewehr 90 rifle (the civilian version of the rifle issued to Swiss Militia), pump action shotgun, and a SIG-Sauer pistol, Smith and Wesson revolver. Fired more than 90 shots.
Leibacher has married three mail-order wives from the Dominican Republic, the first of the three (Villegas) aged 15.
News of this massacre received little play, because of its proximity to the World Trade Center attacks.
