The Zug massacre was a mass shooting that took place on 27 September 2001 in the parliament of the Canton of Zug, in Switzerland. Friedrich Leibacher shot and killed 14 people in the parliament before killing himself. He was armed with an assault rifle, a pump-action shotgun, two handguns and a homemade bomb and had entered the building disguised as a police officer. All of the weapons used were legally obtained. It was the first time a Swiss politician was killed since the 19th century.
