>> brooke, we certainly know that adam lanza was armed to the hills when he went to sandy hook elementary school and had an arsenal back at the house. we knew that he fired off a lot of rounds at the school. now we know it was specifically 154 rounds that were fired. we always knew that he had two handguns and that bush master assault-style weapon on him, that had three 30-round magazines with it. we now know that he had six additional ones. the new information is that half of those 30-round magazines were emptied already and the rest only had 10, 11, 13 rounds left. we know, too, now for the first time that in addition to that gun safe that he had in the house, we've known about that, that we counted up at least 1,600 rounds of ammunition in that house, in closets and elsewhere in the house. we also know that they found knives, they found additional guns. i have reported from the beginning at least four weapons. we know of two rifles, two bb guns, a .22 caliber revolver. they even found samurai swords. this book, they discovered a holiday card, and inside that holiday card was a check written by adam lanza's mother to her son to purchase a specific model of gun. we know the model, but it's unclear at this time whether it was a handgun or a rifle. nevertheless, that close to the shooting, there was an unspent check that they found inside the house. and we also learned that they heard from a witness on the same day of the shooting, december 14th. this witness said that adam lanza was an avid gamer, really liked the game called "call of duty," that he rarely left the house, was considered a loner, and according to this witness, who they are not naming, sandy hook elementary was adam lanza's life, and he chose to make it his target. brooke? >> susan, thank you so much. mike, couple points susan made about the magazines, because it sounds like he would go through classroom to classroom dropping a magazine, reloading, six times. as a law enforcement guy, what do you make of that, 154 rounds. >> 154 spent shell cases of .223 shell cases from that bushmaster rifle. to me that says tactical reloading. that means he went into these rooms and made sure he had a full magazine. as susan said, three were empty, one had 10 rounds, one had 11, one had 13. so, he changed at least six times. that's tactical reloading. that's what you do if you go into a room as a s.w.a.t. team member, you make sure to have a full mag to meet the threat. these are kids. >> how would he come to know this, how would he know that? >> video games. when you're doing shooting, "call of duty," these are the things you also do if you've got the right kind of game pieces when you're playing these games. he was supposedly playing these a lot. one of the other disturbing things, we heard reports his car right outside sandy hook elementary, brooke, was another weapon, come to find out it was a shotgun, a russian-made shotgun that looked similar to an ak-type weapon. 70 rounds of 12-gauge shotgun ammunition and two magazines in that car. >> that doesn't even include the 1,600 rounds at his house. >> ten knives, three samurai swords u just an arsenal. >> what about the sheer amount of time, five minutes going through these classrooms at sandy hook elementary school, like that. >> he came through that window, he was someone on a mission to kill these little kids. that's all you can say, because you can go from one end of a hallway in, tactical reload, reload, boom, boom, boom, reload again. keep in mind, each one of those magazines, 30 rounds. each one of those magazines, 30 rounds, total of 154 rounds of .223 fired in that school, but he also had th the .10-millimeter, which he took his life with, and 9-millimeter. another thing, all these weapons, brooke, they are very, very expensive, and all of them, apparently, purchased by his mother. >> you heard susan mention the holiday check for him for a gun. it's disgusting. >> it is. >> thank you very much. gun control supporters are trying to breathe new life into a push for post-sandy hook elementary school legislation. for the very first time, a new ad campaign features families of some of the sandy hook victims. >> we dropped jesse off in the morning, december 14th, he gave me a hug and a kiss and said, i love you, dad, i love mom, too. >> our daughter grace was 7 years old. she couldn't wait to go to school. she would skip down the driveway. >> my sister loved teaching at sandy hook. >> some of those sandy hook families converged today on the white house, where an impatient president obama renewed his call for congress to act to prevent more sandy hook. for that part of the story, let's go to jessica yellin. jessica? >> reporter: today at the white house, president obama seemed to try to shame members of congress into passing new legislation to reduce gun violence in the nation. as you say, he was surrounded by 19 women on the stage, all of whom were impacted by gun violence, some of them mothers of victims of the sandy hook shooting. here's some of what the president had to say. >> less than 100 days ago that happened. and the entire country was shocked. the entire country pledged we would do something about it and this time would be different. shame on us if we've forgotten. >> reporter: the president pointed out polling data, brooke, which showed that 90% of americans support background checks for gun purchases, but here's another polling figure that points to some diminishing support for fast action on gun control measures. 57% of americans supported tighter gun control laws right after the sandy hook shootings. 47% support it now. it's dropped 10% since those shootings took place. perhaps one reason the president is pushing to get something done before the numbers might fall even further, brooke. >> jessica, as the president stands there today and says shame on us, talks about legislation, what kind of legislation are we talking about here? >> reporter: right. so, the senate's goal is going to come back from easter recess, spring recess, and take up a measure that bundles together a bunch of proposals that will include stricter background checks on firearm purchases, limiting purchase, where i might ask you to buy a gun for me, and more funding for school safety. what it does not include, an assault weapons ban and any limit on the high-capacity magazines. that's what you were talking about just a moment ago, the ability to go in with massive clips and do serious damage, brooke. >> jessica yellin at the white house for us. thank you. also today, we're keeping an eye on the stock market for you and what's looking like a milestone day. check out the numbers right now two hours away from the closing bell. folks, this is the last day of the best first quarter for the dow since 1998. so, the dow is still trading at record highs. it's up here more than 11% at 36 points right now. s&p 500, it topped its all-time closing high today. the s&p is up almost 10% so far this year. markets are closed tomorrow for good friday. nelson mandela rushed to the hospital in the middle of the night. he is said to be conscious. he is said to be responding to treatment. he's suffering from a recurring lung infection. a doctor telling cnn it's likely pneumonia. it's the second time this month the 94 year old has been hospitalized and it's no secret he's become increasingly frail in recent years. >> always has to be concern, and, therefore, the doctors we need to appreciate, we prefer to work on the side of caution rather than take risks. >> mandela's being given antibiotics and oxygen. doctors keep a close eye on his condition. south africa's president is asking the world to pray for the nobel laureate. just ahead, a frightening story out of a hospital involving a doctor accused of killing patients at random. we're learning more as to why. plus, living on the edge of landslide. look at this, swallows one home, now dozens more are at risk. we'll tell you what home owners are saying about this sight.
