Article Photos: Five days of fear: What happened in Boston 9/11

FILE - In this Friday, April 19, 2013 file photo, police in tactical gear conduct a search for a suspect in the Boston Marathon bombings, in Watertown, Mass. The bombs that blew up seconds apart near the finish line of the Boston Marathon left the streets spattered with blood and glass, and gaping questions of who chose to attack and why. Since Monday, Boston has experienced five days of fear, beginning with the marathon bombing attack, an intense manhunt and much uncertainty ending in the death of one suspect and the capture of the other.
