Pressure cooker bombs suspected in deadly Boston Marathon blast

BOSTON (AP) — Federal agents zeroed in Tuesday on how the Boston Marathon bombing was carried out — with kitchen pressure cookers packed with explosives, nails and other lethal shrapnel — but said they still didn’t know who did it and why.

An intelligence bulletin issued to law enforcement and released late Tuesday included a picture of a mangled pressure cooker and a torn black bag the FBI said were part of a bomb.

The FBI and other law enforcement agencies repeatedly pleaded for members of the public to come forward with photos, videos or anything suspicious they might have seen or heard.

“The range of suspects and motives remains wide open,” Richard DesLauriers, FBI agent in charge in Boston, said at a news conference. He vowed to “go to the ends of the Earth to identify the subject or subjects who are responsible for this despicable crime.”

President Barack Obama branded the attack an act of terrorism but said officials don’t know “whether it was planned and executed by a terrorist organization, foreign or domestic, or was the act of a malevolent individual.”

Scores of victims remained in hospitals, many with grievous injuries, a day after the twin explosions near the marathon’s finish line killed three people, wounded more than 170 and reawakened fears of terrorism. A 9-year-old girl and 10-year-old boy were among 17 victims listed in critical condition.

Heightening jitters in Washington, where security already had been tightened after the bombing, a letter addressed to a senator and poisoned with ricin or a similarly toxic substance was intercepted at a mail facility outside the capital, lawmakers said.

There was no immediate indication the episode was related to the Boston attack. Senate Majority Leader Harry Reid said the letter was sent to Republican Sen. Roger Wicker, of Mississippi.
