(Newser) – The FBI has released images of the remains of a "pressure cooker" bomb used in the Boston marathon attack and the backpack it was hidden inside, ABC reports. The second bomb was also hidden in a backpack, but it's not clear whether it was also made from a pressure cooker, the FBI says. Investigators say the bombs—packed with BBs, nails and pellets to maximize shrapnel injuries—may have cost less than $100 to build and were made from ingredients so ordinary that tracing them may be impossible, reports the Washington Post.

Investigators believe the bombs were triggered with "kitchen-type” egg timers instead of cell phones and used a common explosive like black gunpowder, the New York Times reports. "The black powder, or smokeless powder, you can buy in Walmart or gun shops. It’s used for hobbies,” a former ATF assistant director says. “All you need is a fuel and an oxidizer, and the Internet is great for explaining how to do this." Experts say that while the simple bomb design suggests the attack was the work of an amateur, it could also be the work of a master bombmaker expertly covering his tracks.

WHAT does the COST of the device have to do with ANYTHING????? What a STUPID prospective, are we now comparing the value of lives with the instruments of destruction??? SICK Take a LONG walk off a short pier Quinn. On a separate note I understand Ca. Sen Dianne Feinstein is now preparing legislation that would require background checks and a ten day waiting period for buying pressure cookers!

Not to minimize the damage the victims suffered, but quick, we need to do a background check on those who purchase things from Walmart, AceHardware, you name it. After all, it's not just assault guns that kill, but guns are more fun to pick on. You can't stop all harm even if you put the entire population in a rubber room and tied their arms behind their back. But the left will say we need more laws. But couldn't one say that the laws already in place make bomb making illegal? So why more laws. Point being, the mass stabbings last week in Texas, bombs this week, drunk driving, guns aren't the only weapon but its not as "sexy" to pick on other things as well.
