More details have emerged from Boston, as officials continue to comb the area for clues about Monday’s bombings. The Globe says officials now think the two devices were detonated by timers, set just 12 seconds apart, rather than by remote control. The timers were fastened to pressure cookers that were filled with nails and other projectiles to “increase the carnage.” The devices were left at the scene of the marathon in black nylon bags.
