PHOENIX – According to the Federal Bureau of Investigation, pieces of black nylon and what appear to be fragments of BB’s and nails that may have been contained in a pressure cooker have been recovered from the area of the blasts at the Boston Marathon.

These items will be examined and reconstructed at the FBI’s laboratory in Quantico, Va. The pressure cooker was destroyed in the blasts, but former FBI agent Jack Callahan said it is still of great use to investigators and could lead them to the person who bought the pressure cooker.

“Well, you know, you might get to know what the brand is, who sells that brand,” Callahan said. “We go back to, hypothetically, Walmart. Is there surveillance film at Walmart of an individual or individuals purchasing that? Is there fingerprints on it? Is there DNA on it?”

Callahan notes how these tiny details can eventually lead to a big break in the case, referencing the Lockerbie bombing of 1988.

“That was solved by a fingernail and DNA,” Callahan said.

According to the FBI, multiple agencies are investigating the cause of the explosions and Callahan said the task could be disrupted with such uncontrollable factors as weather.

It could also be as simple as finding a hair.

“That is possible,” Callahan said. “You want to know who is at that site. It’s also good for elimination purposes.”
Every detail counts and law enforcement officials are asking the public to submit photos, videos and tips. The FBI asks anyone with information, images or details about the explosion to call 1-800-CALL-FBI (1-800-225-5324) and prompt #3.
