SPREE KILLER

A spree killer, also known as a rampage killer, is someone who embarks on a murderous assault on his victims in a short time in multiple locations. The U.S. Bureau of Justice Statistics defines a spree killing as "killings at two or more locations with almost no time break between murders."[citation needed] Serial killers are different in that they have cooling off periods between attacks, while mass murderers typically stick to one location.[citation needed]

Notably large spree killings in history include:

* Tsuyama massacre (Japan, 1938) - Mutsuo Toi, using an old Japanese rifle and swords, killed 30 and then himself.

* Uireyeong massacre (South Korea, 1982) - Woo Bum-kon killed 57 and then himself, using grenades and a high-powered rifle.

* Port Arthur massacre (Australia, 1996) - Martin Bryant, using two semi-automatic weapons, a CAR-15 and an L1A1 SLR, killed 35.

* Virginia Tech massacre (United States of America, 2007) - Seung-Hui Cho, using two pistols, killed 32 and then himself.
