Boston Marathon bombs were made with pressure cookers
The explosives used in the deadly Boston Marathon bombing were contained in 6-liter pressure cookers and hidden in black duffel bags on the ground, a person briefed on the investigation told The Associated Press on Tuesday.
Two bombs ripped through the crowds at the Boston Marathon, killing three people, including 8-year-old Martin Richard and wounding more than 170, were fashioned out of pressure cookers and packed with shards of metal, nails and ball bearings.
The Huffington Post reported that these types of pressure cooker explosives have been used in Afghanistan, India, Nepal and Pakistan, according to a July 2010 joint FBI and Homeland Security intelligence report. One of the three devices used in the May 2010 Times Square attempted bombing was a pressure cooker, the intelligence report said.
Jeff Lanza, another retired FBI agent, said the Boston case “bears striking similarities” to the bombings at the 1996 summer Olympic Games in Atlanta, in which Eric Robert Rudolph planted three pipe bombs with “lots of shrapnel,” killing two and injuring 111 people.
Lanza also said the smoke color seen at an explosion – which in the Boston case was white – will help indicate the type of bomb used in the blasts.
Another source said that the FBI is scanning cellphone tower records for the “moment of detonation.” If the moment of detonation is positively identified, the corresponding cellphone number can be traced.
Investigators in Boston are combing surveillance tapes and pictures from Monday.
