for those who love the 12 souls cut down in the washington, d.c. navy yard there will never be a satisfying answer why it happened. there is good reason how a man could walk into a government building with a gun and move floor to floor for an hour before police could take him down. new surveillance video of aaron alexis offers cautionary clues and pea year thomas digs in. this is aaron alexis armed with a sawed off shotgun, hunting innocent victims seen here for the first time in new and chilling fbi video. it started as a routine monday at the washington navy yard. alexis shows his pass and is waved in by a security guard. just before 8:00 a.m. surveillance cameras capture him

driving into a parking garage. moments later walking in through the front door of building 197. stop, rewind. the sawed off shotgun might be in the backpack you see right here. but there is no metal detector, no bag check. alexis is supposed to be there. he has been hired as a civilian contractor, working on the building's computer system. according to the fbi he first goes to a men's bathroom on the fourth floor. there may believe he ready himself for the rampage, leaving his bag behind. we next see alexis armed with a shotgun, checking doors, peeking around corners, looking for someone, anyone to ambush. slow down the tape. look at how methodical he is. calm yet urgent. trying to catch some one unsuspecting. watch closely, he sees some people and ducks behind a wall. when you look again, you can see the intent. the stalking. and over the course of

approximately one hour shoots and kills a dozen victims, wounding four more. and today -- the next official explanation on what drove alexis to kill. >> mr. alexis was a mentally unstable individual. he was able to obtain a firearm. >> the shotgun is the primary weapon. on it he etched a number of carvings including "end to the torment" better off this way, and my elf weapon. alexis had been holding voices and believed he was bombarded by microwaves, something naval authorities knew about. >> there are multiple indicators that alexis held a delusional belief he was being controlled or influenced by extremely low frequency or elf electromagnetic waves. >> in his computer files, the fbi found a perhaps telling message. ultralow frequency attack what i have been subject to for three months.

to be honest that's what has driven me to this. >> where did the system break down? >> various encounters across the country. various encounters with doctors as well. i can't comment on where it may have broken down. >> red flags were clearly missed. could have been some mental health assessment done in order to determine the severity of the hallucinations. >> reporter: there is no indication that was done. 90 minutes after alexis entered building 197. police shot him dead. >> there are indicators, alexis accepted death as a con convention of h convention -- consequence of his actions. >> thanks to pierre. >> team usa was the underdog in the america's cup until fortune and the wind turned. stay with us.
