Acid bombs detonated by robotsMay 24, 2012 The Associated Press
ROCK SPRINGS (AP) -- Bomb technicians have used robots to detonate explosive devices found just outside Rock Springs, near White Mountain.
Sweetwater County sheriff's officials and firefighters say a hiker spotted the devices Tuesday morning and called authorities.
Bomb squad technicians found 20 acid bombs or bottle bombs made with household chemicals that were already expended.
They disrupted six more that had apparently failed to explode.
Also at the scene was a homemade, grenade-sized, unexploded improvised explosive device with a substantial explosive charge.
Sheriff Rich Haskell said Wednesday that it's common to see acid bombs around graduation time, but the potential for death with an improvised explosive device is very high. He says it's a federal offense to build such a device.
No arrests have been announced.
