BOSTON (AP) - The FBI is confirming that pressure cookers may have been used in the Boston Marathon bombings that killed three and wounded more than 170. FBI special agent in charge Richard DesLauriers spoke at a news conference Tuesday. He says pieces of black nylon and fragments of ball bearings and nails were found and authorities believe the bombs were placed in a dark-colored backpack or bag. A source close to the investigation had said earlier that the bombs were made in 1.6-gallon pressure cookers, one containing shards of metal and ball bearings, the other packed with nails, and both stuffed into duffel bags. A second person briefed on the investigation confirms that at least one of the explosives was made of a pressure cooker. Both spoke on condition of anonymity because the investigation is ongoing.
WASHINGTON (AP) - A person briefed on the Boston Marathon investigation says the explosives were in 6-liter pressure cookers and placed in black duffel bags. The person says the explosives were placed on the ground and contained shards of metal, nails and ball bearings. The person spoke on the condition of anonymity because the investigation was ongoing. The person says law enforcement officials have some of the bomb components but did not yet know what was used to set off the explosives. President Barack Obama said Tuesday the bombings were an act of terrorism but investigators do not know if they were carried out by an international or domestic organization, or perhaps by a "malevolent individual."
BOSTON (AP) - Massachusetts General Hospital's chief of trauma surgery says doctors removed "a variety of sharp objects," including pellets and nails, from the wounds of victims of the Boston Marathon explosions. Dr. George Velmahos said Tuesday that in his opinion the metal fragments came from the bomb and not from the environment. Velmahos says MGH treated 31 victims of the bombs that exploded in quick succession on Monday. The hospital performed four amputations and he said at least two more patients have legs that are still at risk of amputation. Dr. Stephen Epstein of the emergency medicine department at Beth Israel Deaconess Medical Center says he saw an X-ray of one victim's leg that had "what appears to be small, uniform, round objects throughout it - similar in the appearance to BBs."(Copyright 2013 The Associated Press.
