This morning a stretch of 2 1 2 miles of streets remain closed here in Lower Manhattan. You can hear the Police Helicopters flying above us and there is a large number of federal and local authorities investigating the scene here. Theyve been doing it throughout the night and will continue to do it throughout the day as they try to put together the pieces of last nights deadly terror attack. New video this morning shows the moments immediately after 29yearold suspect Sayfullo Saipov transrr into a weapon designed to inflict mass casualties. I need an ambulance right here. Reporter his path of terror down new york citys west side highway ended here. The kid right there. Reporter after he crashed direct lie into this school bus carrying Children Home on halloween. We got multiple casualties. This is a mass casualty situation. Reporter dozens of bikers and joggers enjoying the unseasonably warm day when a little after 3 00 p. M. The truck veered onto the pedestrian walkway. The white pickup truck, the front was completely smashed in and there were Service Smoke coming out of it. Reporter it careened for ten blocks mowing down everything and everyone in its path. Sources say the suspect exited the truck shouting allahu akbar, brandishing whats been identified as a paint ball gun and pellet gun. I hear one of the young girls say hes got a gun. Reporter this cell phone video shows the suspect frantically dodging between cabs evading police while his victims lay strewn on the ground. I seen a path and when i was looking seeing if theres anybody else i heard about nine or ten gunshots. Reporter police eventually shooting the suspect in the abdomen and taking him into custody. This was an act of terror. A particularly cowardly act of terror aimed at innocent civilians, aged at people going about their lives. Reporter neighborhood schools put on lockdown for hours as parents raced to find their children. I saw the man with the guns. He pointed the gun at me. Im sorry. I have to go get my child. Reporter overnight in new yorks annual halloween parade authorities on heightened alert. Police adding extra officers, heavy weapons teams and sand trucks as protective blockers along the route. Its a memorable experience . Heck yeah. You never think it would happen to you but it happens. Reporter new yorks governor urging people in this city to go we didnt want to let it stop us. We know in times like these too it brings new yorkers closer together and doesnt stop from new york being a safe place. Reporter and at last nights new york citys halloween parade you would never have known there was a terror attack a few hours earlier a few blocks away by the mood and the size of the crowd. 2 Million People flooded the streets of new york city. Your only clue perhaps last nights parade was any different than the ones from previous years was the enormous amount of police presence. Much more so than in earlier years and, in fact, i think its safe to say last night the safest place to be on halloween perhaps was that parade. You were there at the parade last night. You know, in new york weve been braced for this for so long but hasnt been an attack like this since 9 11. Talk about the mood there. It was festive, george. And we saw people and talked to people who were new yorkers, people who had come from all over the world and all didnt even hesitate. Once they heard the news to come to last nights parade and in fact wanted to be a part of what new york does so best come together in moments like this and it was a feeling of celebration not one of sadness and of see sill jens, people werent going to let the terrorists stop them from doing what they wanted to do that evening. Okay, amy robach, thanks very much. Over to robin. Joining us two people who saw that terrifying attack, Andrew Howell and babatunde ogunny, thank you both for joining us. How are you doing . I imagine youre still processing what you saw, andrew. Its pretty shocking. I mean, this is a place of recreation, a place of repose, you know, i work nearby. Use this bike path all the time and certainly not something you expect to see. No, and you go to college right down i go to the Community College which is right across the street. You were between classes. Yes. What did you see . So, we walked over to the pier. Like i said its a recreational area. A lot of people walk dog, you et cetera and we had been sitting there and you just see a white truck at the light and its kind of revving its engine and thinking why is this person being so aggressive. He jumps the curb and hit two people and at that point did he lose control of the vehicle . Whats going on . Whats happening and then later maybe ten seconds after you hear gunshots so now its like its just commotion, everybody is running around. You heard gunshots and didnt know if it was coming from the driver or what was happening. Andrew, what did you see . I was walking along the path southward. It was a beautiful afternoon and just heard this very loud noise, just not a news you expect to hear of this truck going by. Usually no vehicles there at all. Nothing going as rapidly as that one was probably 50, 60 miles an hour, fortunately for me it missed me. But impacted with a cyclist probably 20 feet in front of me and the cyclist was hit by hit the wds up in the air and landed on the ground. It just didnt make any sense to see Something Like that. The truck continued on south and thats when it impacted the school bus at chamber street. You saw that you saw the impact. I did. Did you see the driver at all. Yes, well, the car kind of spun over and was then facing east i saw the driver get out of the car. That was a bit far away like a block and a half away from me and then fled on foot. About a minute later is when we heard the gunshots. What did you think was going on . What was happening . More so the main thing it was surreal. One of those situations you hear about things like this on the news and see it on tv, even movie, et cetera and its just like you dont ever think it can actually happen so actually seeing it all unfold and happen in front of me was just kind of crazy. Yeah, you go to school here. You work here. Youre from jersey. You saw the from amy and people went out to the parade and there is this feeling of resilience and bonding, do you think . Sure, yeah, i mean, life in new york will go on. These are events that weve heard about around the world and the first time Something Like this has happened in new york. Its very shocking and disturbing but something we are going to wake up today and go on with our lives. Just speaking between the two of us and he mentioned he has to go to work today. I have to go back to school. Its just a regular day. The day after. Yeah, that says something that these things continue to happen and we dont want to become desensitized by what were seeing and feeling but also you dont want it to control your life going to school, going to work, doing what we need to do. Thank you so much for coming in and sharing your story. I hope you both do well. Im glad youre doing well. Thank you. Michael. Thank you, robin. This morning were learning more about the victims, tourists visiting new york. Plus, were learning more about the hero officer who stopped the killer. Gio benitez is outside Bellevue Hospital here in new york city where some of the victims were taken. Good morning, gio. Reporter hey there, michael. Good morning to you. Five of the victims are here at this hospital. Theyre being treated right now, eight of them are at another hospital nearby. This is attack happening in the blink of an eye. Among the dead five High School Friends from argentina visiting new york city to celebrate their 30th graduation from high school. The home depot truck plowing into them as they took a group bike ride. We need buses to vestry and chambers. I got at least four on the ground here. Reporter more than a dozen injured and eight killed as First Responders rushed to the milelong crime keen in Lower Manhattan. I was able to see the bodies and three destroyed bicycles as well as all the police, firefighters, bomb squads, s. W. A. T. Team arriving on the scene. Oh, my god. Oh, my reporter six died on the scene. Two at the hospital. One is a belgian national. This morning several victims are still clinging to life at two new york City Hospitals while this man, 28yearold nypd officer ryan nash is being hailed as a hero. He put an end to the terrorists rampage by con fronting him then shooting him in the stomach. I want to commend response from our nypd officer on post near the location who stopped the carnage moments after it began. Reporter nash a sixyear veteran was responding to a separate incident in the area when he rushed to the carnage. The long island resident commanded saipov to drop his weapons which turned out to be a paint ball and paint gun. Nash shot him keeping him alive so authorities could get more information from him. No doubt about it a hero right there. Now we know this morning that at least three of the victims are in Critical Condition right now but perhaps the only good news in this story is that at least five of the victims are in fair or good condition. George. Our thoughts are with all the new details also emerging about the attacker, 9 years old from uzbekistan moved to the u. S. In 2010, lived most recently in new jersey. Early this morning the fbi escorted a group of women and outside his home and our chief investigative correspondent brian ross is here with what we know. The attacker won a lottery to get a visa under a special program to come here. Once here authorities tell abc news he went down a road to jihad pledging allegiance to isis and carried out his attack on a country that opened its doors to him. Overnight the fbi searched the home of the suspect in paterson, new jersey, just across the river from new york. 29yearold Sayfullo Saipov, a native of uzbekistan moved to paterson with his wife and three children after living in tampa and cincinnati. Friends said at one point he worked as a driver for uber in new jersey where neighbors there say he kept to himself. He wasnt friendly at all. Its like he didnt want anyone he was stand offish. Reporter Police Believe they found his vehicle in the parking lot of a home depot where he rented the truck and Officials Say he left notes behind in the truck indicating he carried out the attack for isis. Isis has tremendously persuasive online videos and recruitment tools. Persuasive to a particular kind of person, to a person who is jem generally male and disgruntled. Reporter theyve been asking them to carry out attacks. He grew up in tashkent where applied for an won his visa in 2010 under the Diversity Immigrant Visa Program for residents of countries that havent sentiment immigrants to the u. S. Coincidentally it was an uzbek immigrant in stockholm who police say hijacked a truck and five people. That is the scene right there. Well show it right there, the scene in new jersey right now. And, brian, we are learning the fbi is investigating that saipov he had been on the radar of Law Enforcement at least tangentially. He came under investigation as a possible accomplice of another suspect. But there was never enough proof to open a case on him and he wasnt under surveillance and this morning in a hospital. Hes expected to survive and authorities are now drawing up federal terrorism charges against him. Okay, brian,thanks very much. George, President Trump calling the attacker sick and deranged and saying he ordered Homeland Security to step up the extreme vetting program. Were seeing more types of these attacks using vehicles as weapons and our senior just first correspondent Pierre Thomas is in washington with more. What are you hearing from Law Enforcement officials about that . Reporter robin, good morning. Law enforcement is deeply concerned that these vehicle attacks especially those involving large trucks are becoming the preferred killing terrorists and wannabes. The evidence is mounting and its disturbing. Since 2014 theres been more than 17 vehicle attacks worldwide and 173 People Killed and more than 600 wounded. It only takes deadly intentions, a vehicle and set of keys and isis every day on social media is urging radicals and unhinged to attack any way they can. We recall those in london, france and germany and its happened here too. Not just involving islamic radicals. There was the attack at ohio state by a man allegedly insp e inspired by isis but charlottesville where 19 were injured and a young woman was killed. The president promised extreme vetting. What does that mean. Reporter the white house isnt comment so no one in the administration can tell us what hes talking about. Its unclear whether the quote stepping up vetting would have made a difference in this case because the suspect has been radicalized recently. The bigger issue is why he wasnt on the radar before the attack, but its a tough job, robin. The fbi has more than 1,000 radicals under investigation or surveillance right now. Got to keep that in mind. More from our contributors. Ray kelly right here, former fbi special agent brad garrett down in washington. Ray, let me begin with you. Youve been there. Take us behind the scenes and police headquarters. Top priority overnight. What are they doing right now . Theyre certainly assisting in the investigation. The investigation will be done by the joint Terrorism Task force which is an fbi entity that has about almost 200 fbi officers in t the investigation will involve nypd and fbi agents. Theyre going to do a daylight crime scene search and thats what is keeping the area blocked off as far as traffic is concerned and want to get all of the technicians they can on the scene to look at that crime scene in daylight to pick granular information they can about this individual or, you know, what his motivation was. Also beefing up security across the city. Exactly. The other thing increasing uniform presence at areas where people congregate. Okay, brad, this is fitting in all too familiar profile here. No question about it, george. I mean thissing looks like a classic lone actor attack. So what youre going to do is youre obviously going to look at his phone, his family, his mosque, his job. And social media to see if there are any connections and as brian pointed out, you know, he was involved in another investigation. What does that mean . Youll pull all this together to see who this guy is and did he plan this alone . Yeah, and the big question is was there anything more than inspired. Was he directed. Ill guess that he probably was not because as you look at every one of these attacks that pierre lone wolfs. Okay, brad garrett, ray kelly, thank you very much. Michael. Thank you, george. Well go to ginger with the weather and, ginger, its a little chilly in the east.
