First Bomb Reconstructed Already
Less Than 24 Hours After Detonation

FBI AND ATF BOMB EXPERTS have already compiled evidence that shows that the bombs were packed in pressure cookers, then carried in backpacks, set down and detonated by a remote control.

Boston Globe

Associated Press is reporting:

The bombs that ripped through the Boston Marathon crowd appear to have been fashioned out of ordinary kitchen pressure cookers, packed with nails and other fiendishly lethal shrapnel, and hidden in duffel bags left on the ground, investigators and others close to the case said Tuesday.

Officials found that the bombs consisted of explosives put in common 1.6-gallon pressure cookers, one containing shards of metal and ball bearings, the other packed with nails, according to a person close to the investigation who spoke on condition of anonymity because the probe was still going on. Both bombs were stuffed into duffel bags, the person said.

At a news conference, Richard DesLauriers, FBI agent in charge in Boston, confirmed that investigators had found pieces of black nylon from a bag or backpack and fragments of BBs and nails, possibly contained in a pressure cooker. He said the items were sent to the FBI for analysis at Quantico, Va.

Pressure cooker bombs are popular devices used by Al-Qaida, but their plans on constructing them are widely available on the interenet after they were publish in the terrorist organization's English-language magazine four years ago.

The Telegraph writes:

The recipe – along with a rationale for post-9/11 terror – was printed three years ago in al-Qaeda’s English-language promotional online magazine, Inspire.

In an article, it instructed readers on how, as its headline writers put it, to "Make a bomb in the kitchen of your Mom." It gave the types of explosive, timers and other ingredients needed – along with, it said, a pressure cooker.

The Richard Family / Zuma Press

Bill Richard's family were all gathered near the finish line to cheer several friends of theirs  as they came to the flag.  His young daughter had run in a kid's race on Saturday and was ecstatic over winning a prize ribbon.  One of the blasts killed the oldest son Martin, age 8, (left, above) and his mother Denise suffered a brain injury.  The little girl lost a leg and lived through it only for the fast and efficient work of a nearby paramedic.

NBC News reports:

"My dear son Martin has died from injuries sustained in the attack on Boston," father Bill Richard said in a statement released on Tuesday. "My wife and daughter are both recovering from serious injuries. I ask that you continue to pray for my family as we remember Martin."

Friends and neighbors in the Richards’ middle-class neighborhood of Dorchester, Mass. were stunned by the family’s loss.

The family was a "typical, all-American, lovely family," neighbor Margaret Admirand said, choking back tears. "It’s devastating. He was an adorable little boy," she said. "It’s very hard to talk about. He was a sweet little kid."

Paul Norden, 31, and his brother, J.P., 33, were being treated at separate hospitals on Tuesday, their worried relatives rallying around them.

Paul’s girlfriend was being treated for burns at a third hospital.

The brothers, both roofers who had recently been laid off, were at the marathon to support their friend, firefighter Mike Jefferson, who escaped injury.
