Boston Marathon bombing: what the suspects' arsenal reveals (+video)
The quality and quantity of the Boston bombing suspects' armaments suggest a future attack was planned, but don't answer the question of whether they had outside help.
The alleged Boston Marathon bombers had an arsenal of weapons that went beyond the explosive devices used at the marathon – and which could have been intended for use in subsequent terror attacks.
That’s the picture that has been emerging from law enforcement officials one week after the deadly attack at Boston’s marathon finish line.
A criminal complaint against Dzhokhar Tsarnaev, filed Monday as he was being cared for at a Boston hospital, allege that he and his brother, now dead, wielded guns and numerous explosives as they were being pursued by police days after the initial bomb attacks.
"We have reason to believe, based upon the evidence that was found at that scene – the explosions, the explosive ordnance that was unexploded and the firepower that they had – that they were going to attack other individuals," Boston Police Commissioner Edward Davis said in an interview on CBS News Sunday. "That's my belief at this point.”
The brothers allegedly used handguns and a rifle during their confrontation with police, but had no firearms registered with local authorities. The New York Times identified the rifle as an M-4 carbine, a weapon capable of firing in multi-bullet bursts.
The Tsarnaev brothers also threw or dropped explosive devices, apparently loaded from their Cambridge, Mass., apartment into a hijacked car, Commissioner Davis said. The devices caused "one extremely loud explosion” and several others, he said.
