Surveillance video showed alexis moved deliberately down the hallway, checking door ways, hunting for people to shoot. Within five minutes, legacy moved to the third floor. He carefully exited a stairwell use, protected positions like a trained sniper looking for new targets. As he moved toward them are a small group of people at the end of the hallway appeared to be scrambling for safety. In releasing the pictures today, f. B. I. Assistant director Valerie Parlave said the evidence showed alexis acted alone and had planned his assault as a suicide mission. There are indicator indicatot alexis was prepared to die during the attack and that he accepted death as the inevitable consequence of his actions. Parlave said there is no evidence alexis ever shared his plans with family, coworkers or friends but he left behind numerous clues that spoke to motives. His shotgun carried four scrawled messages. On the right side and barrel were the etched phrases, not what you all say. And end to the torment. On the left side, better off this way. And me e. L. F. Weapon. Investigators say e. L. F. Refers to extremely low frequencies. Information retrieved from alexis cell phone and lapdop indicates he believed outside forces were using e. L. F. To control him. A document retrieved from the Electronic Media stated ultralow frequency attack is what ive been subject to for the last three months. And to be perfectly honest, that is what has driven me to this. Reporter that message and others were found on computer files inside alexis backpack, the same bag he used to sneak the shotgun into the building. Now, investigators say the rampage was not directed at any particular person. While alexis, it surgeons out, was disciplined on the job just three days before the peak, theres no evidence he targeted his boss, his coworkers or anyone hed even met. Pelley bob, there are hours of surveillance tape. The foib released 30 seconds. What is on the rest of tape . Reporter terrible images, scott. The tape shows alexis moving through the buildings. Obviously it shows the moments of violence and gunfire. But its important to say here the f. B. I. Thought it was proper to release 30 seconds. Ist shows himself acting alone with no help but they have no intention of releasing the other horrific images, scott. Pelley the f. B. I. Is also on the scene of the Shopping Mall siege in nairobi, kenya. At least 72 people were killed from gunman from a sho maury terrorist grouped swarmed the mall in kenya on saturday. Charlie dagata is at the mall with the latest. Reporter today, five days after the attack, more bodies were pulled from beneath the rubble of the westgate mall. New video released by the kenyan government shows the full extent of the destruction. Three floors collapsed after a fire and a series of explosions crippled of the shopping complex. Today, it was still smoldering. Forensic teams from the United States and europe joined the investigation, sifting through the rubble, gathering evidence. Bomb disploazal teams from the f. B. I. Began fingerprint, d. N. A. , and ballistic analysis to help determine the identities of the victims and the alhelp shabab gunmen. Government officials would say little about the attack today, other than it appeared to be well planned. The massive amount of firepower subtles the militants may have rented a store to stash their wbz inside the mall ahead of the attack. There are indications that the militants may have hired a shop inside the mall. Theyve been planning this for several months. Is there anything you can tell us about that . Whether the terrorists hired a shop in the mall is a rumor we have heard just like you, and we will treat it as such until the forensic exercise and any other investigation taking place prove it otherwise. Reporter flags were flown at halfstaff today to mark a threeday period of mourning as kenyans continued to hold funerals for the dozens of victims killed in the attack.

Reporter you have made a speech. The president has made a speech. There was no handshake. No bilateral meeting between you and the president. You suggested you didnt have enough time to plan for it. Whats necessary for you to have a bilateral meeting with the president . translated well, after all, were speak of two countries who have had no relations for 35 years, so its clear that to begin talks requires some preparation work, and whenever the prep work is completed, i believe that its possible to have a meeting. Perhaps if we had more time here in new york, we may have been able to coordinate what was necessary for that meeting to take place. Pelley charlies complete interview with president rouhani will air tonight on the charlie rose program on pbs. But portions will also be shown tomorrow on cbs this morning. Now to that budget battle in washington and the possible Government Shutdown next week in a dispute over obamacare. In a cbs News New York times poll out tonight, 80 of americans say threatening a shutdown is no way to negotiate. If there is a shutdown, 44 say they will blame the republicans, 35 said they would blame the president and the democrats. One republican who is in the thick of this is ted cruz of texas. Hes fighting a losing battle in the senate to make sure any budget deal cuts off funding for obamacare. Cruz completed a 21hourplus talkathon on the senate floor today, and nancy cordes is on capitol hill. Reporter after 21 hours and 19 minutes, ted cruz stepped off the senate floor and declared victory. This was all about elevating the debate in the public and giving the American People a chance to speak. Reporter but once other republicans had the chance to speak, they said they disagreed with cruz and did not want to hold up a funding bill and risk a Government Shutdown just to wage a doomed fight to defund obamacare.

That allegation, in my view, does a great disservice, great disservice for those brave americans and those who stood up and said whats happening in europe cannot stand. Reporter all 100 senators, including cruz, vote today to formally begin debate on the funding bill. Cruz is trying to convince his republican colleagues, scott, to try to block the passage thaft bill later in the week. Pelley nancy, thanks very much. You know, we wondered earlier today, whether senator cruz had made the cut in historys Longest Senate speeches. The Research Department tells us that number one is strawm thurmond of South Carolina who spoke against a Civil Rights Act for 24 hours and 18 minutes. Alfonse do mountaino of new york tried to save a favorite defense contract, speaking 23 hours, and 30 minutes, and Wayne Morrison went 22 hours and twaix minutes, which means senator cruz has secured his place in history at number 4. It caught our eye today when a Major Medical journal reported a remarkable advance in merging man and machine. Dr. Jon lapook has a look at a new prosthetic leg controlled by the awarers mind.

Reporter researcher Levi Hargrove and a team at the Rehabilitation Institute of chicago engineered the device. You just think about moving along, the device pushes you along, pushes you upstairs, helps control you when you walk downstairs, and it does everything in a seamless manner. It really blew my mind the first time that we did that. It was Pretty Amazing experience because i hadnt moved my aichgle i ankle in a way that i could see for two years. Reporter the army funded this research hoping to improve the lives of the more than 1200 soldiers and aprisoldiers and ae million americans who have lower beg amputations.
