grieving, others in relief and joy. and abc news's dan harris spent the day with survivors. >> diane, we spent all day here at what was in many ways, the emotional epicenter of this story. the volunteer firehouse right down the street from the school where we watched many families holding tearful reunions with their children and also families who weren't so lucky. all day long here at the firehouse where the students were kept safe after the shooting, an urgent parade of parents coming to pick up their children. this is 8-year-old alexis wasik and her mother. >> you were in there? what happened? >> we heard like an ambulance and a police officer come and everybody was a little scared, crying and i felt actually a little sick. thought i was going to throw up. >> were kids crying and screaming? >> yes. kids were crying, not really screaming, but they were all

huddling together and felt so sick. >> reporter: her mom said when she arrived at the firehouse, alexis was with her father. >> he had her in his arms and were crying and she just goes, momma, i'm okay, i'm here. >> reporter: another mom whose kids go to a nearby school told us she was putting off picking them up because she didn't want to tell them about the horror here. >> this is the last few hours of their life that they're going to be a kid. >> reporter: we don't know much about the victims yet. there are the reports about the principal, dawn hochsprung, being among those who were shot. >> you can tell she loved her job, she loved the kids. sandy hook was a safe school. >> just monday she tweeted this upbeat message about kindergartners making their own shopping list and paying the cashier at a local supermarket. only three victims were brought to the local hospital. two of them died. >> a number of us imagined what it must have felt like on 9/11

when there were people bracing for scores of injured and they didn't arrive. >> all day long the sight of ambulances driving slowly, lights not flashing. so few wounded to try to save. even more sad, the knowledge that so many families who showed up to pick up their children could not be re-united. a fact that is not lost on alexis's mother. >> you count your blessings every day. >> reporter: i'm really glad you're okay, alexis. you're pretty tough. you're pretty tough. adding to the shock, this place is such an unlikely venue for violence, a classic, small, sleepy southern new england town, where tonight they're following another part of the all-too-familiar script after these mass shootings, they're coming together to hold candlelight vigils. diane? >> all right, dan, thank you so much. and all day long, of course, we've been trying to find out

more about the 20-year-old suspect in this shooting and right now abc's chief investigative correspondent brian ross is back with what he knows at this hour. >> reporter: as you and dan reported, this all took place in the small town of newtown, connecticut, a place where everything is nearby. the spree ended at the elementary school, but began at the lanza family home. authorities identified the shooter as 20-year-old adam lanza, seen here in a picture taken seven years ago and provided to abc news by a family friend who told us adam was obviously not well. something we also heard from a newtown real estate agent, barbara frey, a family friend. >> he was not connected with the other kids. my son played with him when they were young. and in her home, i know she was very particular. i just think she maybe had too high a standard or something, or

focused too much, for whatever reason. >> so was there conflict or tension between the two of them? >> the parent and child? >> yes. >> not that i know of, but the fact that the parents were divorced must have contributed. >> the mother was the first to die according to police. adam's father and brother are being questioned by authorities in new jersey, where they live. diane? >> brian ross reporting and once again, we want to give you the latest now on those who were injured. the victims who are recovering tonight in the hospital. for that we go to amy robach who has been following their stories. amy? >> good evening to you. this has been the most traumatic event anyone at this hospital has ever experienced, that's what i heard from a physician here who also is the president and ceo of danbury hospital. he talked about the moment he received the phone call expecting two dozen victims

who will come here requiring immediate medical care. he amassed 80 doctors and nurses, the finest surgeons available to be prepared for anything and everything, and they only received three injured victims at this point. they said about ten minutes later, that's when they realized that no more were coming. it's important to note, he said, this obviously affected everyone who was in this hospital at the time. all the police officers, the firefighters, the children and teachers inside the school, the parents, there is no one in this community who wasn't affected. this means this is going to be a community that will require medical, emotional care for years to come. they have set up services that people can access 24 hours a day, seven days a week. they actually have mobile labs spread out throughout the community to help anyone who feels a moment of crisis because this is something they will deal with, they're bringing it home to their family. he told me it was the single most traumatic event he's ever experienced or considered in his

professional or personal life. those are fairly weighty words from an emergency room doctor who you would think had pretty much seen it all. he and i don't think anyone in the community had ever prepared to see anything like what they saw today. >> thank you, amy. now i want to bring back "20/20" anchor chris cuomo, because you talked to parents who had to wait to see if their children survived. >> imagine the first word they got was the school was on lockdown. they thought their kids were making gingerbread houses today at the elementary school. that was the plan. they rushed there, there's chaos, to be imagined in these situations, but to not know for so long. not because of disarray, just because of the situation. inside are the children living through this event. those who survived, their parents hope someday they'll be able to forget. we spoke to one little girl and her mother who are very happy to have each other tonight. what do you remember?

what happened? >> we got to school. did everything we needed to. we heard all this racket in our classroom. we were like all scared. then we heard them say, go into your cubby. >> everybody went to their cubby? >> yes. >> did you hear any more bad noises? >> yes. >> reporter: while that was going on, your teacher was reading you books and keeping you calm? >> yes. >> you have a good teacher, don't you? >> yes. >> you love your teacher. did she seem nervous? >> no. >> she just kept her calm and told you a story. >> yes. >> do you remember which one? >> she read us the nutcracker and another book that was about christmas. >> reporter: i love the nutcracker. do you love it? >> yes. >> reporter: i'm afraid of the mouse king. a little scary, let's be honest, it's not just me.

this, leading these kids out, making sure they had their eyes closed but those teachersed that their eyes wide open and they got the kids to safety as many as they could. >> they knew that was the main thing they had to do and they called on all their courage and their training. thank you so much. we do love her smile. now we want to turn back to washington where president obama did speak today about the tragedy in his emotional press conference, talking as commander in chief and as father of two young daughters. here abc's chief white house correspondent jake tapper now. >> reporter: as flags were lowered to half-staff at the white house this afternoon. >> our hearts are broken today. >> reporter: president obama reacted not as a president, but as a parent. >> i know there's not a parent in america who doesn't feel the same overwhelming grief that i do. >> reporter: it was an emotional side of the president rarely seen in public. he repeatedly wiped away tears and paused to compose himself. >> the majority of those who

died today were children, beautiful little kids between the ages of 5 and 10 years old. they had their entire lives ahead of them -- birthdays, graduations, weddings, kids of their own. >> reporter: it was almost two years ago the president was called to be consoler in chief after a different act of gun violence in tucson where congresswoman gabby giffords was shot and six others were killed. >> we mourn with you for the fallen. we join you in your grief. >> reporter: today the president recited a grim list of other places now known for horrific gun violence on his watch. a shopping mall in oregon, a sikh temple in wisconsin, a

movie theater in colorado. today the president suggested he might take some action. >> we're going to have to come together to take meaningful action to prevent more tragedies like this regardless of the politics. >> the only action we know for sure he would take is this one. >> this evening, michelle and i will do what i know every parent in america will do, which is hug our children a little tighter, and we'll tell them that we love them. and we'll remind each other how deeply we love one another. >> reporter: earlier tonight, the president was scheduled to spend time with the first lady and first daughters, we're presuming that hug took place. house speaker john boehner announced that he would forego the traditional weekly republican address so the president could speak for the entire nation at this time of mourning. >> all right, jake, reporting in from the white house. still ahead here on "world news," more from the tragedy of the elementary school. we asked the experts, the fbi profilers, about the men behind these gun assaults.

shooters have serious mental health issues. >> usually the attackers will tell other people beforehand what they're thinking about and planning to do. >> reporter: they often exhibit warning signs. some of the indicators are blatant. other signs are more subtle and only become clear in hindsight. diane, there are an estimated 200 million-plus guns already in circulation in the u.s. the fact is disturbed people are going to get them. one source predicted tonight we're going to see this sad situation unfold again. it may be days, it may be weeks or months, but he said, it will happen again. >> thank you, so much pierre thomas. when we come back, this remarkable school struck by tragedy, considered one of the top in the nation. when we come back, we'll tell you why so many people say, this school is special. next.
