I can tell you his mother nancy lanza was found dead at the family home here in newtown, as well. She had been a teacher at the sandy hook Elementary School. The schools principal dawn hochsprung was among those killed and tonight a friend remembered her as quote, the kind of person you would want to be educating your kids. School psychologist Mary Sherlock was also kilged. This afternoon afternoon the brother, ryan lanza was taken in for questioning by police and he was handcuffed. Officials did not label him a suspect. The gunmans father was also questioned in relation to what happened here today. Tonight, a nation in mourning. Candle light vigils were held in newtown and across the country. There was one just outside of the white house in washington, d. C. Earlier today, president obama ordered flags to be flown at half staff nationwide in tribute to the victims of this terrible tragedy. In an emotional address, he said this to the nation. I know theres not a parent in america who doesnt feel the same overwhelming grief that i do. 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 the president , incredibly emotional as he. A masser of innocent tiny children and the weapons used nothing short of terrifying. Our Susan Candiotti has been following the developments today. Three different weapons found in different places, very, very dangerous weapons. Thats right. Two of the weapons were found on the shooter himself n the classroom where he was found dead. One of them is a glock and the other is a cigging sauer. Both handguns. A third weapon was found in a car in a vehicle, may have been his outside of the school. Is that the vehicle that had been parked erratically and roped off with the crime tape . Exactly. They were paying a lot of attention, closely examining the car. The third is a semiautomatic known as a bushmaster. 223. We understand all of the weapons belonged to his mother. His mother was a schoolteacher at the school. They were registered in the state of connecticut, as well. Trying to piece this all together, why did she have those guns . How did he get them . Just one area i know will be a huge topic of conversation for days and months to come. Another big question for so many the names of these children. There are 20 children who died. There are six adults who died in the school. Theres nancy, the mother who died in her residence. When will we find out the official identities of these victims . Right. Law enforcement authorities are telling us it will be tomorrow morning. They expect to be releasing the identities. They have been working diligently to check, double check and triple check that they have all of the right people and obviously that everyone, members of the family have been notified. Expect to hear that in the morning. So sad to see by exclusion they have made the identities obvious to family members who did not get reunited with their children but the positive i. D. S they talked about a forensic project they will be working on where the childrens bodies are. Thank you so much. We appreciate it. You are welcome. Our drew griffin has been busy working on whatever information we can find on this person, the shooter. Adam lanza. What have you found out, drew . Having covered so many of these, in fact with Susan Candiotti it is playing out almost in a sickening routine a shooter with a possible Mental Health issue with family, possibly trying to deal with those issues, smag snaps, powerful guns easily accessed and you have an outburst of violence. The case is playing out just exactly in that order. Heres what we know the 20yearold shooter had an older brother. That brother reportedly told abc news, the brother had a personality disorder. He also mentioned his brother had autism or was autistic. Cnn heard the same flfgs a man who called himself a friend in newtown where the shooter lived. So we are seeing a base for some Mental Health questions being raised. One more question. And drew, niquickly, is anyone talking about warning signs . Other than what i just mentioned not yet. I expect we will see more detail on that. Right now, also somewhat standard in these cases, you will find people shocked this person could have been involved in anything like this. Listen to what we heard from a former classmate and a former School Bus Driver who knew this 20yearold. Just a kid. Just a kid. Just a kid. Never antisocial . No. No. Troublemaker. No. Definitely not. Noticeable . Did he just blend in to the background . Yeah. Nothing that would warrant any of this. They are saying he went after his mom and her class of kids. Can you wrap your head around that . No. I cannot. I dont know anyone who would do anything like this. So your general sense is what . This is unspeakable. I first heard about it. Im still in shock. Give me a moment. I want to go. Im going to go walk around. He was a nice kid, very polite. She raised very nice boys to me. Thats why i think it is a shock to even though them and realize who they are and what he did. You cant understand what happened that he snapped, have what you and he took such innocent lives. Aim . Im convinced in the coming days, even tomorrow there there were warning signs, Mental Health issues and a family that felt they had nowhere to turn. We have seen it in Virginia Tech and the shooting of Gabrielle Giffords in aurora, colorado. Im sure we will see that. What we will not see really for the families is any kind of explanation that will make sense of this. Right now it is just senseless. Just so unbearably difficult to digest, especially here on the scene. Without question something had to be terribly wrong. Drew griffin reporting for us live. Thank you so much. Theres one name you will likely hear more of. Her name is katlin roy. She is a first grade teacher at sandy hook Elementary School. She is being hailed as a hero. She saved a number of students in her classroom. She spoke exclusively with diane sawyer earlier. Have a listen. In my mind im thinking, you know, as a 6, 7yearold, what are your thoughts . What are your im thinking that i have to almost be their parent. Like i have to tell them, you know so i said to them. I need you to know that i love you all very much and that its going to be okay. Because i thought that was the last thing they were going to hear. I thought we were all going to die. I dont know if that is okay. You know teachers. But i wanted them to know someone loves them and last thing that they heard not the gun fire in the hallway. Just horrible. Horrible. Incredibly emotional story. Im joined by the hopkins family, bob and his children julia and bobby. Bob, i want to ask you about a friend of yours whos a basketball coach here in town who has two children attending sandy hook. One of those children was a first grader who witnessed something absolutely unbelievable. I want you to recount for me the story if you will. Absolutely. Just spoke to them an hour or so ago. Any way, his young son was in class and the shooter broke in to the classroom an and in front of his eyes gunned down the teacher. He was astute enough to take a couple of the students and he ran out the door behind the back of the shooter and ran out of the school and continued to run for a half mile until he hit the main road. A stranger picked up the kids and took them to the Newtown Police department. Unbe knownst to the parents when they went to talk to the state troopers, et cetera, their son was unaccounted for. So they told them to look in the woods, go door to door, talk to people and for an hour or so they had no idea where their son was. They called the Police Department a couple of times and they had no record of him being there. Finally after an hour and a half they called and were relieved to find out their son had been dropped off at the Police Department safe len sound. At that time they must have thought the worst. They thought the worst. It was very difficult time for them. He said it was the worst hour and a half hes ever experienced in his life. Police interviewed this first grader, im guessing hes 6, 7 years old. Hes 6 years old. They did interview him since he was there. What was he able to tell them . What details. They asked him, the interview was very elementary but they asked what he saw. Asked his recollection of the room. He said i saw a bunch of silver bullets on the floor of the classroom and when i got out to the hall i saw a bunch of bullets in the hall and they werent silver. They were red so unfortunately covered in plood in the hallway and from that point he just ran and sprinted at the school. Did he give a description any further about the shooter, his face . Did the shooter say anything. Did he have a look in his eye, anything like that . He didnt say the shooter said anything. He described what he looked like. It is a very elementary description because hes 6 years old. His descriptive skills are not that acute. Julia, you have a different story. You are in the middle school here in town. You went in to lockdown right away as soon as this happened. Did you know what was happening . I know everyone has cell phones and might have been Text Messages but did you know what was going on . No. I had no clue many what was going on until the first hour. We were in lockdown. A teacher said there was a shooting down the road. You have a classmate who has a little brother at the school. The boy i was sitting next to during the lockdown, his little brother ended up dying. How did he find that out . Im not sure. I havent talked to him yet today but i know during the lockdown he didnt say anything. I didnt even know he had a little brother at Sandy Hook School until i found out his brother had died. He hadnt been concerned at the time of finding out the fate of his brother while he was in lockdown in your classroom. It didnt seem like it. Bobby, you were in another school, as well. And you also fwhent to lockdown. What was the experience for you . What happened. It was a little different because we were in church at the time, school mass and monday se monsignor said we needed to end mass and go in to lockdown and we sat and waited. We could hear sirens for an hour. Did you, like your sister, also eventually find out what was going on . Yeah. We eventually went back to the school and my class was locked down in the basement. Our teachers told us there had been a shooting and there were fatalities but i didnt know the seriousness of it until my dad picked me up from school and on the car ride he said there were quite a few fatalities. Are you okay . We went to the vigil at 7 00 which was emotional. You are awfully young to be digesting. None of us is handling this well and you are awfully young, you and your sister. It didnt really sink in. I was numb up until the vigil and then i think everyone broke down at the vigil because it was so sad to see everyone there and see actually 28 candles on the alter to represent the victims. Actually just pass the mic to your dad. Bob, an incredible moment at the vigil. There was a letter read from the pope. It was a letter written by Pope Benedict to our community specifically, which was very touching. And very meaningful and meant a great deal to the whole community. On top of that it was emotional for us is month senior weiss talked about in his homily the time he spent with the 20 families today and in particular mentioned two little angels, one of whom the mother of the victim said she went out recently and got her first communion dress and her daughter was very excited about that and the other little angel was going to be playing an angel in our school play at saint rose next week. It was a poignant story and very emotional for us to hear and digest. How is your friend, the basketball coach whose child went through this harrowing ordeal . I think the best way to describe it is traumatized. Hes a wonderful man, wonderful person, wonderful family. Although he is incredibly grateful that his son is safe, his heart is certainly bleeding for the other children in the classroom because two of his sons classmates did parish in the saga they told you. When the gunman came in, that was the second classroom he came in and two of this boys classmates were killed today. And he witnessed it. He witnessed his own teacher being shot. Thank you very much. Our hearts go out to all of you hear. The nation is in mourning with everybody here in newtown. I hope you are going to be okay and hug your kids tight. We will. Thank you. Coming up next, the haskins family just touched on the vigil and the message that came from half way around the world. The governor was here, in the senators were here. We will give you a better feel for what it was like inside the church later on. [ male announcer ] this is steve. He loves risk. But whether hes climbing everest, scuba diving the Great Barrier reef with sharks, or jumping into the market, he goes with people he trusts, which is why he trades with a company that doesnt nickel and dime him with hidden fees. So he can worry about other things, like what the market is doing and being ready, no matter what happens, which isnt rocket science. Its just common sense, from td ameritrade. This is a community of 27,000 people. It is quiet and spacious and the houses where trees stretch for long periods between houses and still a close town. And people know each other. And thats why they needed something, anything to try to come together after the horrors that they were forced to endure today. The fact that so many of their children in this community will no longer be with them. They gathered at a Catholic Church in town called saint rose of lima. Jason carroll was there for the vigil and it was standing room only. There are hundreds of people that came out. As you said, they wanted something, anything. They were leaning on each other and leaned on their faith and thats why they came here today. No question about it. Spoke to a deacon who said, as you said, when you have a community this close it should be no surprise. When you have hundreds of people that come out, most of them at the church tonight knew someone at the school. If it wasnt a child it was a parent. If it wasnt a parent it was a teacher. If it wasnt a teacher it was an administrator. Thats why they came here today for comforting words that they got from monsignor robert weiss who read a letter from the pope. I convey my heart felt grief and the assurance of my personal prayers to the victims and their families. To all of those in the community of newtown and especially the parish of saint rose of lima. In the aftermath of the senseless tragedy, i ask god our father to console all of those who mourn and sustain the entire community with the spiritual strength which triumphs over violence by the power of forgiveness, hope and reconciling love. And one of the deacons here at the church when i spoke to him about what he was doing he said throughout the day he had received 100 people that come through church doors looking for comfort and answers. Many of them asking why, why Something Like this could happen and all he could say is i told them sometimes there are no answers. Not now. It is too soon. Maybe this is something only god can answer. Jason, one of the adults, one of the six adults killed in the school was the School Principal named dawn hochsprung. Have you learned anything about her . You are hearing so much about her from so many people out here. 47 years old, two daughters three step daughters. She had been the principal at sandy hook elementary since june of 2010. She was constantly twittering. So proud of her school. Twittering about the fourth graders just this week. From all accounts she was a woman who loved her student and her job. When we talk about this Close Community it no surprise to find a man out here who knew her and knew her well and i want you to listen to what he had to say about her. Dawn the principal at sandy hook i had dinner with her last spring. She was an incredible educator and to lose somebody like that in our district it is sad because they lost a leader today at sandy hook. My prayers will be for, you know, our community, as well. As you heard him say, lost a leader in this community. Dealing with this loss, dealing with the pain and suffering, this is what this community will be having to try to cope with from this point on i mean for days, weeks, months and certainly for the parents of those children. Theres no saying how long they will be dealing with their grief. So distressing, jason, to know the principal had just this fall implemented a brand new Security System where you had to get buzzed in at 9 30 in the morning and yet this was perpetrated against her school. Jason carroll reporting for us live across town from where i am. Part of the reason i am where i am right now is that the media has been getting regular updates at this location, not only from the state police but also from connecticuts governor who has come at regular intervals not only at the location to brief us but he has spoke on the the families. The families given the terrible news they would not be reuniting with their children and he made another stop at the vigil jason just reported on. Heres some of the things he told those in grief. Good evening, everyone. Month senior, thank you very much for opening this very Beautiful Church so that we might in a communal way find solace in one another. As a result of the unspeakable having occurred in this community. Peoples children, brother and sisters were taken from them. Peoples spouses, teachers and administrators were taken from us. Yet we stand in a church and many of us today in the coming days will rely upon that which may have been taught and that we inherently believe that there is faith for a reason. And that faith itself is gods gift for all of us. In these times of troubles when the unthinkable happens in our very midst, our faith is tested. Not just in the religious sense. Not just necessarily our faith in god, but our faith in community and who we are and what we collectively are. Its in so many ways permissible to have those thoughts and those doubts about who we are and what we are and what community reps. But then we turn to understand as we turn around in this room and recognize our friends and our neighbors, those we are done things for and those who have done
