A law enforcement source tells CNN Producer Carol Cratty the search of Pfc. Naser Jason Abdo’s hotel room and backpack turned up:  six pounds of smokeless powder, Christmas lights and battery operated clocks which were apparently intended to create a timing and triggering device of some type, sugar, shrapnel, pressure cooker, shot guns shells that were in the process of being dismantled to obtain their raw explosives.  The suspect also had a military uniform he had purchased.

This official described the literature found in the backpack as “Islamic extremist literature.”   He also had a shopping list of components he wanted to get to make a bomb.  The official did not know if there were still items he had yet to get.   And he had a .40 caliber pistol in the backpack.
