From the story:
Also:Police identified the weapon as an Uzi, an Israeli-made submachine gun.
http://en.wikipedia.org/wiki/Uzi
The Uzi (Hebrew: עוזי, officially cased as UZI) is a family of Israeli open-bolt, blowback-operated submachine guns. Smaller variants are considered to be machine pistols. The Uzi was one of the first weapons to use a telescoping bolt design which allows the magazine to be housed in the pistol grip for a shorter weapon.
