Handguns, a rifle and at least six bombs -- three of which exploded -- were found at the scene early Friday after officers first confronted the two Boston Marathon bombing suspects in the darkness of a residential street, the Watertown, Massachusetts, police chief told CNN's Wolf Blitzer on Saturday.
A single officer was the first to encounter the two cars that Tamerlan and Dzhokar Tsarnaev were driving, just before 1 a.m. Friday, Chief Edward Deveau said.
Before the officer could get backup, the two cars stopped, and the brothers got out.
"They jump out of the car and unload on our police officer," Deveau said "They both came out shooting -- shooting guns, handguns. He's under direct fire, very close by. He has to jam it in reverse and try to get himself a little distance."
Five other police officers, including two who had just finished their shifts, then arrived at what Deveau called a "very tight area" in the middle of an intense shootout. One of the officers was wounded.
"We estimate there was over 200 shots fired in a five- to 10-minute period," Deveau said.
One of the brothers threw an explosive at the officers. They later discovered it was a pressure cooker bomb, similar to the ones used at the marathon Monday, the chief said.
