NEW PHOTOS: Possible Boston Marathon Bomb Fragments Found

New photos of what may be parts of the explosive device detonated at the Boston Marathon Monday have been released. They show what looks like the top of a presure cooker, charred wire attached to a battery, a half inch nail, blood stained zipper pull tab and what looks like a mass of small ball bearings used as shrapnel to inflict the most possible damage. The investigation meanwhile continues into who plotted the deadly attack that has so far claimed three lives.
