A musical is changing how some people think. We begin tonight with the High School Shooting in centennial, colorado tonight and were learning more information about the shooting and the victim. The shooting happened at arapaho high school, the student was carl pearson, shot one students then turned the gun on himself. Arapaho hi is only shortly from aurora, colorado, where students were killed in a Movie Theater s conference with the sheriff, lets learn more about what had he to say. There may have been some controversy or some disagreement between the teacher and the student that we know was the sheert. Shooter. And we believe his motive may have been a reaction to the disagreement or that confrontation. The first thing that many people thought about when they , this area of colorado has been the crucible of the debate over gun violence. The only blessing people are talking about today is this did not turn out to be a mass event. One thing we did learn when the shooter came into the school on the West Entrance there were 65 to 80 students in that immediate area close enough to see and hear him as he came into the school and began shooting. Scenes of relief as parents were reunite wednesday their children. Were reunited which with their children. What they asaw and heard. Running towards where the shots happened, we heard more shots and everyone got up and went into the street. Just after 12 30 in the afternoon. The school was evacuated, students running outs with hands in the air. Police patting them down one by one as other officers swept the building. More than 2200 students attend arapaho hi, only eight miles from columbine. Its was something that ran be through everyones mind. Scared, really squared. We moved here right after columbine. Is was really nervous. Each one of those parents ind rather terrifying fact is there were two insendary i in inin cendiari. Paul beban in centennial, colorado, thank you. When parents learned of the shooting they rushed to the high school to see if their children were okay. This morning i was with my prayer group and we were praying to keep evil out of the schools. And it happens. My husband has been trying call me to let me know there was a shooting here. Just luckily my daughter had texted me already. So i was relieved to know she was at least safe at the time. Scared to death. Scared. We moved here right before columbine so i was really nervous. Parents are showing up going crazy, we could just not get ahold of our kids. Ive got two kids in the school and ubl lots of obviously lots of friends with kids. We were telling them who we found and didnt find. It was crazy. Best thing ever that shes okay and her friends are okay. Im good. It just keeps happening. Its unfortunate, whatever the situation is, this poor person who took his own life must have been just so fraught with something. Unfortunately for residents of colorado Mass Shootings isnt new. Ago at the aurora shooting. People saying, i cant believe this has happened again. The community is deaf stated. What sort of support do they need right now . Well, they need one another. So the parents, the children, the staff, the faculty, they really need to lean on one a traumatic event like this. You know obviously this brings up other shootings not just in colorado but all across the country. Were at the anniversary of newtown, connecticut where i live. And i know the impact that it had on the state of connecticut at that time. It brings back memories for parents and kids. Do you have any advice o that ce advice of getting back into a going to protect you. You are reassure them. Especially Young Children if theyre aware of the news, might have nightmares, so again were reassuring kids, letting them get that extra hug, but let them take the lead in the pace of what they want to discuss. You spent some time out in colorado so can you imagine when the aurora theater when that tragedy happened last summer. In my class of about 25 students i asked them how many of you which are there or knew someone who was there and almost we havd these tragedies in the past, we will survive and come out strong. Peggy norwood thank you for your advice. Thank you john. This weekend marks a year since the shooting at newtown, how difficult that can be. In illinois, enhanced security and lock down drills have been mandatory since 2005. Usher carashi has more from chicago. In niles, illinois security is taken extremely seriously. Before gaining entry visitors enter a secure vestibule where they must present identification at this window. Using what is called the raptor security system, an instant background check is performed, cross referencing against the National Sex Offender registry. In addition, in case of a problem, a bullet resistant shield can be pulled down and a panic button directly informs police. They added this new entrance, more secure entrance. Formerly, the entrance to the school was stairs and up stairs, no assurance our be visitors would go where they were supposed to go. Its all part of a 5 million upgrade of their security system. In 2005 illinois passed the School Safety drill act that requires schools to perform annual lock down drills, earlier this month the lake school are put their plans into action when there was report of a student with a gun coming to class. The school immediately launched their code red lock down procedures, students huddled in classrooms for hours and eventually evacuated without incident. 13yearold schuyler was in the school at the time. I was finding relief there was no shooting, no guns involved. I was just very thankful that the school handled the so well and i was able to get out safely. Security president palm tim have implemented security protocols in hundreds of districts including lake zurich. There are only two times we know that our procedures work. During an emergency which is an unfortunate time to find out they dont. And during drills and as a result they are ready. It is a tough balance say educators between making the place safe and a learning environment. We are always looking at better ways to make our students safe, because we know when theyre safe, theyre going to learn. Its a procedure they dont want to put into action. Usher careshi, al jazeera. New england could see more than afoot of snow. The winter storm warning starts tomorrow and Rebecca Stevenson has been watching all of that. Rebecca. Yes, john, we are expecting to see the snow totals go up quickly. In fact we are expecting to see about 14 inches of snow in new england 50 time we get into sunday evening. Snow heavy at times in illinois, chicago will wake up with two to four inches. Just south of chicago we are expecting six to eight inches of snowfall. Temperatures dropping and wind chills in places like minneapolis or chicago, you need that type of moisture to come up. Weve got that now. Heading a little further north were going ohave problems with ice in virginia and also West Virginia where we could get potentially a 10th of an inch of ice accumulating. The snow will continue to increase into new jersey and into manhattan, about one to two inches expected in new york city. Higher amounts near the great lakes, where eight to ten inches will fall around the great lakes acknowledge ontario where we already have two feet on the ground. John. All right rebecca. Reuters is reporting that an earthquake is shaking buildings in tokyo, we dont have any information beyond that, but well bring it to you in the broadcast. Later on, detecting earthquakes is helping l police fight crime. And the grandson of Nelson Mandela talks about how his life has changed forever because of him. A sheriff in colorado says a Student Armed with a shotgun may have been seeking revenge when he started shooting in a Denver School that day. The teacher had learned of the threat and already left the building. The shooter shoot himself. The u. S. Has pioneered an acoustic system that can pin points the shooting and where it occurs. Jacob ward has the story. In many ways oakland, california is the Perfect Place to live. Its warm and beautiful here. Are its an hour from the pacific, three and a half hours from yosemite. But like many other places in the country, this city is plagued with the sound of gun fire, as many as eight shootings a day. Not only is gun fire per you vasive, its very loud. Police know about gun fire, shot spotter is one of several Companies Selling such a system. The technology is born out of earthquake detection which has also been adapted by the u. S. Military to stop sniemers. The Company Installs microphones in communities inflicted with voyages. The system can triangulate the shooter. The system may also reveal just how inaccurate our understanding of gun violence is in this country. Official estimates are based to 911 calls, but most gun fire doesnt result in either outcome. Unfortunately when somebody fires a gun, people call 911 only 20 of the time. The first challenge four out of five times nobody knows it happens exeb except the person o pulls the trigger. The gun fire on the exorn he will shoot up the house of the person whos competing with him on the drug territory on the other corner. While the drug be estimate is based on 911 calls. Shot spotters data suggests such incidence may be 80 more frequent with perhaps 2550 times the rounds fired. I think if the American Population knew just how many shooting incidents there are, in which bullets are flying through air, and little kids are listening to gun fire, five, ten, 15 times a night, i think the reaction about the gun debate would be a little different. Not necessarily about legal weapons but about the persistent nightly use of illegal weapons, if we measured this accurately we could do what the old business maxim is, you can manage what can you measure, you cant manage what you cant measure. Whether acoustic detection helps police catch criminal. May simply be revealing once and for all just how many guns are being fired. Jake ward joins us now from san francisco. Jake is this technolog automatii automatic or something else, track the movement of a shooter, if someone pulls the trigger multiple times, the software can show which dir car, perhaps running.

Over there. So nda brvega you mentioned this is your ndaba you mentioned this was a personal fight against aids. Why was that for him . Because my parents died of hiv and aids. My mother was the first who contracted it. My father contracted it, he died of hiv, aids, we had a conversation together at home, as to what we are going osay. One family members, nurse, said hiv doesnt kill you, it kills your immune system. So he didnt die of aids. My grandfather says no, we are going to say aids killed him we have to fight. What are you going to say about your grandfather . Im very anxious, this week has been very trying, challenging emotionally and physically and mentally. I just want us to give him a i have honorable sendoff. And if there are anything ugh could say to him today, what would it be . I would say granddad, you have inspired us, you have led us.

A sheriff in colorado says 18yearold Carl Petersen was looking for his teacher, a 15yearold girl was shot, in Critical Condition tonight, police say the gunman then fatally shot himself. I believe the shooter knew that deputy sheriffs were immediately about to engage him and i believe that that shooter took his life because he knew that he had been found. Arapaho high school is less than ten miles away from columbine, the cite of another shooting in 2009. Students say the days events bl happened so quickly, the shooter is dead and another is fighting for her life. 12 33, the suspects entered the school with a shotgun. I saw the kid run it was just he saw me kind of did like that and he just kept running. We realized that it was like a gunshot so we all dove into the corner and they came on the intercom and said it was locked down stay where you are. The gunman immediately asked for the location of a individuals specific teacher and he many identified that teacher by name. I thought it was a drill until we heard the gun shots. One student confronted the have shooter and there was a shot. This girl came down hall and said help me help me there is shooting. The shooter is dead as a result of selfinflicted shot.

There was no shootout between the shooter and officers on the scene. Apparently not too long after making it into the school and looking for the teacher he did inflict that fatal gunshot wound. What we plernt a little more this afternoon and this evening that the press conference was about what the shooters goal was, what his target was in the school. I asked th the sheriff this eveg if he knew who was the intended target . Im not going to mention that, we know the teacher, we have engaged but its not appropriate for me to have that discussion. Very frankly, the teacher as i indicatorred, based on his alsoe coach aps name, according to reports was tracy murphy. Its not clear what the past confrontation was, but the sheriff did tell us that they are asking more information from friends and carl pearson would have come to the school today. Rljohn.
