Anti-Tank Grenades Found At Ariz. Neo-Nazi Massacre Site

Six anti-tank grenades designed to be fired from a launcher were discovered on Wednesday at the scene of a horrific Arizona mass murder-suicide, which authorities said was carried out by well known white supremacist JT Ready.

The discovery helped expand the probe of the killings to the federal level and has led investigators with the U.S. Bureau of Alcohol, Tobacco, Firearms and Explosives to begin looking into how Ready was able to obtain the illegal explosives, according to ATF special agent Tom Mangan.

Mangan described the bombs as 40mm armor-piercing projectile grenades, the same type used by the U.S. military in combat. The grenades are generally fired from some sort of launcher, but Mangan said no such weapon was found at the scene.
