Boston Bomb Probe Looking at Pressure Cooker, Backpacks
Boston Marathon bombing investigators on Wednesday entered the third day of their hunt with an emerging picture of the target: a suspect or suspects carrying heavy bags or backpacks made of dark nylon.
While still unable to conclude whether a group or individuals were responsible for the attacks that killed three people and wounded 176, and whether they were foreign or American, investigators gathered enough evidence at the crime scene on Tuesday to slightly narrow their search.
The two blasts struck seconds apart on Monday at the finish line of the race, maiming victims with shrapnel-packed bombs that investigators suspect were contained in pressure cookers. Seventeen people remained in critical condition.
President Barack Obama, who will travel to Boston on Thursday for a memorial service, has called the bombings an “act of terror.” It was the worst bombings on U.S. soil since security was stepped up following the suicide hijack attacks of September 11, 2001.
