Three people are dead, including an eight-year-old boy, and over 170 have been injured after two explosions went off near the finish line of the Boston Marathon on Monday. Police are asking the public for any amateur video and photos that could help the investigation of the Boston Marathon bombing. According to sources, the bombs were reportedly fashioned out of pressure cookers and packed with shards of metal, nails and ball bearings.
FOX News Radio's Courtney Kealy reports from Boston:
The press conference giving key information: that there were two explosions from two explosive devices, but no other unexplosive devices were found. Other crucial information may be awhile to come. Richard DesLauriers, the FBI agent in charge speaking at the press conference:

Confusion and fear struck runners and spectators following Monday's explosions.
FOX News Radio's Kirstin McNary has more on the bombing from a witness:
(Runner) "We knew that this race was over."
The "elite" runners, the fastest athletes, had long since crossed the finish line.
But thousands of others, like this man, were still on course...
(Runner) "I heard a cannon go off. I saw a whole bunch of smoke. I go... 'why would a cannon go off recognizing four hours or something.' I thought it was bizarre. Then I saw the second one go off."
First responders there to control crowds and re-hydrate weekend warriors switched gears in an instant...
(Runner) "With five of my kids, we were finishing together. And then we all stepped dead in our tracks. And the police were just escorting us off. We didn't know what was really happening. It was terrifying."
