The manhunt for suspected Boston Marathon bomber Dzhokhar Tsarnaev had reached its climax. Tsarnaev, who eluded police for 17 hours after an early morning gunfight, had been located aboard a trailered boat in Watertown. The question was how to take him into custody.
“We had to assume he was heavily armed, based on what he’d done,” said Robert Duprey, a member of the State Police SWAT team. “If you approach on foot and he throws a bomb, you’re dead.”
