Boston Marathon Manhunt (1)

When two bombs cut a swathe of death and destruction through the crowd of runners and spectators at the finish line of the Boston Marathon, the FBI steps up to lead a massive manhunt for the perpetrators. As the nation watches transfixed, the Bureau and its law enforcement partners work against time to find the bombers before they can strike again. When the suspects finally emerge, they lead authorities on a deadly high-stakes chase through the streets of Boston.
