A short time ago, I watched the latest presser on the Boston Marathon bombings yesterday that left 3 dead and countless injured. Details released, though sparse, have alluded to ““pressure-cooker” devices that sent sharp bits of shrapnel flying into victims in the vicinity of the blast.”
Surgeons at several Boston hospitals told televised news conferences on Tuesday that the explosive devices had apparently been packed with small pellets and sharp “nail-like” objects that were designed to maim their victims.
The new details about the explosives emerged as President Obama announced at the White House that the F.B.I. was investigating the attack as “an act of terrorism,” but said that it was unclear if it had been carried out by an individual or a group, foreign or domestic.
Two of the three people killed in the bombings were identified on Tuesday, an 8-year-old from Dorchester, Martin Richard, and 29 year old Krystle Campbell, of Arlington.
Special Agent, Richard DesLauriers, in charge of the F.B.I.’s Boston division, said during the presser earlier that “investigators officially began recovering forensic evidence from the blast site on Tuesday morning.”
“Among items partially recovered are pieces of black nylon, which could be from a backpack, and what appear to be fragments of BBs and nails, possibly contained in pressure cooker device,’’ he said at a news conference, adding that they would be sent to the bureau’s laboratory in Quantico, Va. “In addition, this morning it was determined that both of the explosives were placed in a dark-colored nylon bag or backpack. The bag would have been heavy because of the components believed to be in it.”
DesLauriers also stressed that the investigation is “in its infancy,” and no claims of responsibility have emerged since the bombings.
“This is a very complicated investigation,’’ he said. “It is going to be pursued methodically, carefully, diligently, but with a sense of urgency. We are barely 24 hours on into this investigation, so I would say that this is still in its early, early stages, and that’s the best way I can characterize it right now.”
President Obama, who spoke briefly after the incident yesterday, is expected to visit Boston on Thursday to “speak at an interfaith service dedicated to those injured or killed in the terrorist attack against the one of the city’s most beloved events.”
The third person killed in the Boston Marathon bomb blasts was a “Boston University graduate student, the university said on Tuesday.”
University spokesman Colin Riley declined to provide the student’s name or other identifying details.
Light a candle… say a prayer for Boston tonight and the victims of this horrific crime.
