Blown out. New overnight police work to clear explosives and the big question, why did they do it. We have not ruled out terrorism. Complete coverage right now on gma. And good morning, america. We have been tracking all the fallout all night long from that california massacre. The worst mass shooting since newtown. It has stunned our entire country one more time and this time the crisis played out on shootout. Killers. Family members say they were a up. It ended less than four miles away from where the terrible building. Police chasing them from a nearby home. So many moving images from the scene. Escaping. Pausing for a moment of prayer. Rampage. Another 17 wounded. Police say there were just the two shooters, the husband and wife, despite early reports of there being three, both of them were killed in that shootout leaving behind a 6monthold baby. So hard to imagine. There is a live look at where it all unfolded. A center to help people, some of the most vulnerable in our society and our Team Coverage starts with amy on the scene in San Bernardino. Good morning, amy. Reporter george, robin, good morning to both of you. In fact, right behind me across this field is the very building where that horrifying tragedy unfolded and, in fact, you can still see the vehicles, the cars left behind by all of those employees who raced out of that building. Some of them taken by bus. Some of themfof taken by plansambulance. A man left some say in an angry state and returned with his wife and semiautomatic handguns. A firsthand glimpse inside the terror at the social services center. Ill take a bullet before you do. Thats for damn sure. Reporter which culminated in this chase, dozens closing in on this black suv. Shots rang out. Reporter hundreds of shots fired as the married couple inside the vehicle battled with 20 officers. When it was over, the two suspects, 28yearold syed farook who worked in the building and his wife, 27yearold Tashfeen Malik both dead. It started at 11 00 a. M. Male in black clothing still firing rounds. Reporter when the heavily armed couple entered a Conference Room at the Inland Regional Center which serves the mentally disabled during a Work Training conference. Multiple shot, shots going off like crazy, one right after the other. Reporter police arriving on the scene within four minutes, the entire threebuilding many watching from their windows. Making entry through the back door east side. We have several down in the Conference Room. I need some medical aid immediately. Reporter hundreds evacuated with their hands in the air. Syed farook was attending a Company Party at the center but left under angry circumstances only to quickly return dressed in dark clothing armed with assault rifles and handguns opening fire. He was acting nervous, left the building, 0 minutes later or so the shooting began. Based on how they were equipped there had to be some degree of planning that went into this so i dont think they just ran home, put on these type of tactical guns and came back. Reporter countless people terrified taking cover inside the buildings. Everybody just started running through the halls and we squeezed in our Conference Room barricaded the doors. Reporter some phoning their loved ones while bullets were i said turn off the lights and dont make a sound and that he was it. Reporter terry petite receiving this message. In the office waiting for cops. Pray for us. I am locked in an office. Thats it. Reporter the motive of these shooters is still unknown at this time but even if we do ever get that answer, it will do little to ease the pain of this community, this is this nations deadliest mass shooting since newtown, connecticut, back in 2012 that left 26 people dead. Robin. All right, amy, thank you very much. We will get back to you in a little bit. Some of the most compelling video of the rampage was taken from inside the Inland Regional Center. You see police there storming the building. Timmy hilliard who was working there at the time and timmy joins us now this morning. So good to see you, timmy. Were glad that youre okay. We know it had to be terrifying. Where exactly were you when this started to happen . I was right above the building 3 and building 2 where that video shot from on the third floor and one of my colleagues offices, the rest of my teams and colleagues were boarded up into two different Conference Rooms with doors and tables against the doors and i me being a photographer i wanted to see and what was going on out in the with everything thats going on so i actually took video after seeing what i saw to show everybody what else was happening around. And describe what you were seeing, timmy. I saw two bodies laying on the back of the building. One hunched over on a bench a female laying flat on the ground and she neither of them were moving and then within a few minutes the video shows theres s. W. A. T. And everybody else storming into building 3 with alarms going off. You received a text message alerting you to what was happening. Yes, one of my colleagues sent a text there was an active shooting going on and at the time i was thinking maybe there was a guy or a person with a gun Walking Around the facility or the grounds, and then i heard a lot of my colleagues running and stomping and crying, so i went to go see what was happening and then i heard that there were bodies down and instinct of me taking over i went to check out the facility and wanted and had to see what was going on. You jumped right into action like that. Can you give us an idea about the complex, about the facility and how you were able to get out so quickly and safely. Housing for auditorium, facilities, dances, whatever we can do with our consumers and at that time the last video i shot there was there were s. W. A. T. And everybody coming into our facility so my colleagues and i went back to the Conference Rooms and we had a p. A. System alert from the Police Department to come out with hands up with badges in hands to let them know shoot. Were letting them know that we are part of Regional Center as well and i was letting them know at the time that theres at least 50 to 100 upstairs that were coming down. The authorities acted so quickly and saved so many lives and your video just gives us an incredible insight into what you and others had to endure. Thank you. Hey, timmy hilliard, all the best to you, thank you very much for joining us. You take care. Thank you. All right. You too. We are also learning more about the two shooters this the couple had a home and a new baby. Abcs matt gutman is in San Bernardino with more on that side of the story. Reporter good morning, robin. Thats right. This is a middle Class Community of stuccoed condos, christmas wreaths on the doors but overnight we heard an explosion coming out of that house, the bomb squad sending in a robot after officers battered down the door and still at this hour investigators are trying to piece together how and why this plot was hatched. Coworkers describe 28yearold syed farook seen here on an Online Dating profile as a softspoken devout muslim who rarely discussed his religion in the office. Thats nothing i can remember that would lead me to think he may do this type of thing. He certainly seemed mildmannered on his dating profile on this site describing himself as allah fearing, calm, for a girl who would wear a hijab. According to chris nwadike, the Health Safety and environmental inspector born in america found the type of girl he was looking for abroad. He said he found a wife online from saudi arabia. He got permission to go there and marry her. Reporter Police Believe that woman could be Tashfeen Malik his 27yearold accomplice. The couple had a baby and the office, colleagues say, the same one the couple allegedly targeted wednesday throughew a baby shower for them and abc news confirmed they dropped their 6monthold infant off with farooks mother before heading off on that deadly rampage. Telling farooks mother, they had a doctors appointment. Farook reportedly left the building shortly before an office photo in what many describe as an agitated state. He was acting nervous, left the building. 20 minutes later or so the shooting began. Reporter returning, police guns and bops. His brotherinlaw overnight condemning the attack. I have no idea. I have no idea why would he do that. Why would he do Something Like this . I have absolutely no idea. I am in shock myself. Reporter expressing his shock and condolences to the families. I just cannot express how sad i am for, you know, what happened today. Reporter that couple leaving behind, of course, that 6monthold infant, a baffled family and very rattled community here. And investigators still trying to piece together how they stockpiled all those arms, those all that ammunition, the explosives without anybody knowing about it. George. So many questions to sort through right now. Thank you. More answers now from our chief investigative correspondent brian ross, our senior justice correspondent Pierre Thomas and former fbi special agent brad garrett in washington. Brad, let me begin with you. As this was unfolding yesterday afternoon knowing that the shooters had escaped this an far but ended up so close to home, so close to the incident. Maybe for two reason, one they believe they got a clean getaway and to restock. More weapons, more ammunition possibly more explosives because what we dont know at this point was there a round two . A round two and, brian ross, what more are we learning about the possible motives about the shooters . Well, appears to be a hybrid workplace jihad. He had issues, he targeted his coworkers but recently had traveled to saudi arabia where he met the woman he says he married on his website, the dating line website and appears to be an allamerican boy, snowboarding, and guns and likes to relax by going in the backyard for target practice. Pick up on that idea. Seems to be some kind of a hybrid incident. A lot of planning here. Two lines of inquiry. They are looking at the workplace angle. What happened that could have sparked this. Get radicalized online . Was there a meeting or something overseas that could have sparked this, as well. They say they have not made a final determination but those are the two primary thing. This has been such the big fear, the idea you can simply go online and thats how you get inspired. Exactly. And i talked to a senior official just a few moments ago who said that this may be some kind of weird combination, where just last year you had a case in oklahoma where a man beheaded one of his coworkers. That turned out to be workplace related because he had just been dismissed but also they found some material online that may have suggested radicalization. That was the same with ft. Hood and major hassan who targeted his fellow employees at the military base but amirs to have been radicalized online. Debate whether to call it terrorism or Workplace Violence. In the end it didnt matter to the victims. There was a hell of a lot of planning that went into this and my source just told me how did he suddenly go from being that much weaponry. And body armor. The fbi has studieds these Mass Shootings, 160 active shooting situations, only two not done by lone wolves thats correct, george. Have we entered a new era here . I dont know. Husband wife, she looked like she was, you know, a coequal to him during the shooting. Theres got to be, george, some training going on here. Theyre too casual with the weapons from the vehicle inside the hull so where did they train . Who trained them, et cetera. Relatives, brian ross, aspects and echoes of the Boston Marathon bombing. Absolutely, where the family says they were shocked. They had no idea in the case of the tsarnaev brother, the older brother radicalized and the younger brother and tried to lead a normal life. The idea this kind of planning could go on in secret without being detected by anyone. Yes, the secret service just came out with a report yesterday that looked at attacks against government facilities and one of the prime things they saw over and over were missed warning signs. And right now so far nothing is turing up. In this case the involvement of a woman is very unusual. Neither isis nor al qaeda allows women to be warriors or fighters. Theyre not allowed to martyr themselves, a kind of bon think and clyde as it were of terrorism. So much more to learn. I know youll be on it all day long. Back to robin. The shooters killed 14 people. 17 others injured. Many of them taken to a hospital in loma linda and abcs Kayna Whitworth is there right now for us. Good morning, kayna. Reporter robin, good morning to you. Just moments ago i got an update on the conditions of the people that were brought here. In all at loma linda hospital they brought in five Adult Patients yesterday and as of this morning we know that their fair and two are listed in critical condition. Now, this is the only Level One Trauma Center in this area. Other patients were taken to Arrowhead Hospital. We know there six patients were brought in, one person was already released last night. Now, we spoke with the sister of a young woman who was shot yesterday, shes 27yearolds, denise perazzo and this morning the bullet is still lodged inside her. Doctors are unsure whether theyll ever be able to remove it. Hours after the shooting doctors received a bomb threat here and they have been working under a heightened sense of alert ever since that happened. Now, the doctors here are trained for this but we saw emotions running high. They have been attacked at home and they are doing an incredible job. Robin. All right, kayna, thanks very much. So much trauma on the scene right there. Robin, there have been at least 56 Mass Shootings already this weve seen president obama speak after so many of them and addressed this latest rampage last night. Abcs jon karl is at the white house with that. Good morning, jon. Reporter good morning, george. This is the fifth time the president has had a comment on a mass shooting just in the last five months, and in an interview just as the news was breaking about this shooting, the president said instances like this are simply too common here in the United States and even before knowing anything about the shooters or how they got their weapons, he said it is time for congress to pass tougher gun laws. Yeah, we have a pattern now of Mass Shootings in this country that has no parallel anywhere else in the world. And there are some steps we could take not to eliminate every one of these Mass Shootings but to improve the odds that they dont happen as frequently. Reporter and this happened just after the president returned from paris where he visited the site of the deadliest of the attacks that weeks ago laying a rose at a memorial outside the bataclan theatre and called the inability to stop gun violence in the United States the greatest frustration of his presidency and, george, as you mentioned at the top of the show with 14 dead, this is the deadliest mass shooting in this country since what happened in newtown, connecticut, at the massacre at the elementary cool three years ago. Any word whether well hear from the president. Reporter no word but i imagine theres a good possibility it will happen. Jon karl from the white house, thanks very much.
