The Zug massacre was a mass shooting that took place on 27 September 2001 in the parliament of the Canton of Zug, Switzerland. 57-year-old 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.
