good evening. imagine your husband or son or brother or your mother, sister or daughter served this country in uniform overseas in wartime and god forbid imagine they made the ultimate sacrifice and paid with their life. we have all been assured if that happens their remains are treated with great care and the utmost respect every step of the way. sadly we are learning that's just not true in all cases. a scandal is unraveling in washington and elsewhere about how some of our service members' remains have been treated. we start off tonight with our pentagon correspondent jim miklaszewski. >> reporter: dover air force base is the first stop for all of america's war dead on their final trip back home. behind the dignified ceremony there is a growing scandal over the fact that many partial

remains of service members were dumped in this virginia mp landfill and it is a far greater number than previously disclo d disclosed. the air force dropped over 2,700 partial remains in the landfill. nearly 1,000 have been identified through dna, belonging to 274 u.s. military killed in the wars. yet the air force never informed service members' families of the practice. sergeant first class scott smith was killed in iraq in 2006. his widow was shocked to learn only recently that some of her husband's remains are buried in the landfill. >> absolutely mortified. i was so angry and i felt betrayed by my -- you know, by these people down at dover. >> reporter: air force officials struggled today to explain how human remains could be cremated, then dumped right along with medical waste. >> how you dispose of medical waste --

>> they just don't get it. >> reporter: congressman rush holt said he's been trying to get to the bottom of the issue for months and suggests the air force tried to cover it up. >> it is such an obvious, flagrant desecration that if they didn't know it, they didn't want to know it. >> reporter: it's not the only problem at dover. partial remains of some service members have been lost. in one case, the mutilated arm was sawed off a deceased marine so his uniform would fit for burial. this follows the startling revelations that arlington buried some veterans in the wrong graves or lost their remains all together. there are two ongoing investigations into dover. air force officials said they will apologize to those 274 families involved in the landfill controversy. but only if they call.

brian? >> unbelievable story. jim miklaszewski with the news out of the pentagon tonight. jim, thanks. a lot of parents may have heard today a major college campus in this country was on lockdown for much of the day. the campus was virginia tech and the reason was all too familiar. there had been a fatal shooting there. for a time it appeared the gunman was on the loose. it all started with what police describe as a routine traffic stop. our justice correspondent pete williams picks up the story. >> reporter: it was just after noon, the university says, when a virginia tech policeman pulled over the driver of a car in a campus parking lot. police say another man walk aed up and shot and killed the policeman, then ran off toward a nearby rec center building. officers hurrying to the scene found a second body. >> in light of the turmoil and the trauma and the tragedy suffered by this campus by guns, i can only say that words don't describe our feelings and they are most elusive at this point

in time. our hearts are broken again for the family of our police officer. >> reporter: the university immediately sent out a community-wide alert. stay inside, it said, secure doors. call 911 for help. students stayed put as tactical team swarmed through campus buildings. >> they came through, a whole team of s. iw.a.t. team guys clearing out the building. >> reporter: law enforcement officials said they believe the second victim was actually the man who shot the policeman. the campus-wide alert was cancelled and the search for the gunman was called off. >> we have released the campus community to go about their normal activities. >> reporter: students were getting ready for final exams today that were to start tomorrow though they have been postponed. word of the deaths alarmed the campus achingly familiar with violence. in 2007 a student killed two people and then himself. during the attack the university was criticized for waiting more

than two hours to alert the campus. this time the alert went out within minutes. university officials were actually here in washington today appealing the fine imposed by the federal government over the delayed alert four years ago. tonight virginia police say they don't know what the motive was for today's shooting, brian. >> what an awful trauma to go through all over again. pete williams in washington, thanks. former penn state assistant football coach jerry sandusky is back home tonight after spending a night in jail on new child sex abuse charges. this morning posting $250,000 bail. tonight his wife is coming to his defense. quote, as the mother of six children, i have been devastated by these accusations. she says in a written statement, no child who ever visited our home was ever forced to stay in our basement and fed there, she says about one allegation. our children and extended family and friends know how much jerry and i love kids and have always

sales. the pills are particularly popular among young women. critics say a change in labeling is not enough. >> i'm very concerned if they don't take this drug off the market there will be even more girls and women harmed in the future. >> reporter: not all of today's testimony was critical of these popular medications. >> if you think of the millions of women in the u.s. using oral contraceptives, the effective benefit of yaz translates into considerable number of women. >> reporter: the majority of the expert panel this evening voted that the label both for yaz and yasmin should have tighter revisions, but not clear yet what those revisions will be. we asked behr pharmaceuticals for a document or comment and there is no response yet. brian, these are likely to stay on the market. there will be some changes. what the changes will be or how we prescribe or how they are marketed, those are things we'll

in. it is a top of mind topic now and nbc's tom costello has our report. >> mr. baldwin -- >> reporter: on his return to new york alec baldwin was again met by cameras, all for being thrown off a plane when he refused to turn off his iphone and the game he was playing. >> he's a star. he loves to do that. >> i think he needs to abide by the same rules everyone else does. >> reporter: but a question. >> i wondered, why can't i read my ipad while i'm sitting here? >> reporter: the f.a.a. rules are clear. >> ladies and gentlemen, at this time please turn off all cell phones and other electronic devices. >> reporter: everything must be in the off position before the plane pushes back and when it is preparing to land. do they really pose a danger? boeing engineers in seattle showed us the signals that come from the video screens on portable devices. >> there is a potential for these signals to cause interference to the radio.

>> reporter: pilots have complained of interference with their flight computers and radios, but there is no hard proof of it ever causing an in-flight problem or a crash. part of the problem, say the experts, is that mobile device technology is changing so quickly. there is no way of knowing whether the next device that comes along might pose a threat. >> are they okay and are they not? until they are tested the f.a.a. has no way to determine it. >> reporter: despite the rules some press and sports team charter flights ignore them. even those on air force one don't seem worried. all kinds of electronics are used in flight. alec baldwin apologized in a statement for delaying his fellow passengers saying it was never my intention to inconvenience anyone. but he also blamed the flight attendant. the flight attendant union will ask that baldwin be banned from future flights along with his tv show "30 rock." tom costello, nbc news,
