| Bomb probe focuses on bags and pressure cooker |

| BOSTON - The investigation of the Boston Marathon bombing is focusing on a suspect or suspects believed to have carried heavy bags or backpacks, but entered a third day on Wednesday without any arrests or word on who was responsible. Investigators appeared to have gathered enough evidence at the crime scene on Tuesday to slightly narrow their search. A stretch of Boston's Boylston Street almost a mile long and blocks around it remained closed on Wednesday as investigators searched for clues. The explosions sprayed shrapnel far enough that police were collecting fragments from rooftops along the marathon's course. Hospitals are saving the shrapnel pieces doctors pick out of the wounded for police. Dr. Peter Burke, the chief of trauma surgery, said the fragments include metal, plastic, wood and concrete. "We've taken on large quantities of pieces Â… we send them to the pathologists and they are available to the police," he said. Among the items recovered at the bomb scene were pieces of black nylon that could be from a backpack, fragments of ball bearings and nails, and possibly the remains of a pressure cooker device, Richard DesLauriers, the Federal Bureau of Investigation's special agent in charge in Boston, told a news conference on Tuesday. Evidence collected at the scene was being reconstructed at the FBI laboratory in Quantico, Virginia, DesLauriers said. Bomb scene pictures produced by the Boston Joint Terrorism Task Force and released on Tuesday show the remains of an explosive device including twisted pieces of a metal container, wires, a battery and what appears to be a small circuit board. One picture shows a few inches of charred wire attached to a small box, and another depicts a half-inch nail and a zipper head stained with blood. Another shows a Tenergy-brand battery attached to black and red wires through a broken plastic cap. Several photos show a twisted metal lid with bolts. A U.S. government official, who declined to be identified, made the pictures available to Reuters. |
