that i'm chris hansen with "dateline nbc."nd we're doing a story on adults who solicit minors online for sex. >> i have nothing else to say, except, world, please forgive me. it was stupid. >> he makes his way out of the backyard through the garage where police are waiting to arrest him. >> turn around. put your hands behind your back. >> he's taken away in an unmarked car and brought in for questioning. >> why did you come to the house today? >> i was bored at home. >> yeah? what was some of the thing that you discussed? >> oral sex. >> oral sex. anything else? >> think that was it, maybe a massage. >> did you send any photos to this person? >> of my private parts. i'm digging myself a hole, aren't i? he insists that he would not have had sex with a 13-year-old. >> i [ expletive ] up my marriage. i [ expletive ] up my life. i don't deserve any of it. meaning my life, my wife. >> how long have you been married, michael? >> 13 years. >> and there are more married men about to show up at our hidden camera house. this is 43-year-

what is there, what happened and in what order. >> chris hansen, thank you. let's go back to brian in connecticut. >> reporter: well, lester, as you know, i tend to be partial to first responders, anyway. but it tells you something about the scope of this tragedy that even the first responders to the scene today, and those include police officers, state police, but also the local volunteers. even the first responders were all assigned grief counselors because of what they had to see and deal with. the nearest big hospital is in danbury, connecticut. their emergency room was put on full alert just after the shooting. personnel came in. they were warned to prepare for the very worst. sadly, though, that is not what happened. we pick up that part of the story with nbc's andrea canning. >> reporter: after the shooting, the schools were in lockdown, as was danbury hospital, the staff braced to receive the wounded. dr. john murphy is head of the hospital. >> the reason for that is really out of an abundance of caution. we want to be sure that we allow the team to f

joining me now to have some of that argument is chris hansen president of the american cancer societye cancer action network. thank you, chris. you do great work. i'm a big fan of your effort. >> thanks you. it is good to be here. >> as i said, we all support what you do here. but why should we subsidize you. why should my taxes subsidize you. and not just you, but museums and rich guys' alma maters. >> first of all, we add charitable deduction in this country since 1917, i believe is when it went into effect. it is part of our society. it leverages a whole variety of things. if all of the services that are done by not for profits, and there are all kinds of not for profits out there, and what happen says they do a lot of things that governments would have to do otherwise. when people talk about making governments smaller, it is a lot harder if you don't have charitable organizations that do disaster relief and any other number of things. health services, et cetera. let me give you an example of the american cancer society. we are the largest funder of cancer research in the world. in

but why he turned those guns on children is still a mystery tonight. >> and chris hansen joins us now from newtown. chris, has the family been able to shed any light on a possible motive? >> reporter: you know, lester this one still has law enforcement shaking their heads. it is early in the investigation. but as far as they can tell there are no oftbvious indicato as to why he would do this. there are no rantings on facebook, or social media. they really couldn't provide much. in fact, lanza's brother said he hadn't even talked to adam in many, many months. >> and i know right now authorities are involved in that very sensitive and difficult process, the identification of the victims. but that said, do we have any ideas when they might release the names of the families affected? >> reporter: it could be a while. they have one of the best investigative teams in connecticut, if not the world. they are going to go through and find every piece of potential evidence that they can. it will likely be a few days before they wrap that up and they're in a position to actually release the ident

. >> the last of myriad's patents on the breast cancer genes expires in eight years, but if chris hansen way, that could be even sooner. he's the lead lawyer for the american civil liberties union in what could be a landmark case against myriad genetics and the u.s. patent office. the case has the support of nearly the entire medical establishment that deals with genetics. >> all of those people are saying, "the patents in this case hurt women's health." >> hansen says that myriad's patents are unconstitutional and should be invalidated. >> there's a longstanding patent law doctrine that says you can't patent the laws of nature and products of nature and abstract ideas. and that's what happens when you patent genes. >> but what was the rationale of the patent office in approving this? >> that isolating and purifying the gene is so transformative that it makes it a different thing. >> but it's still not an invention? >> they would say that by taking it out of your body and stripping away some of the pieces, they--it's no longer a product of nature. it's now an invention. we think that's n

let's go to chris hansen now on the phone with us making the way up to the scene. chris? >> hi, lester. how are you? >> good. yeah, chris, you're on the air now. are you at the scene now? >> i'm not at the scene, lester. i pulled over to speak with you for a little bit here. i can tell you -- i don't want to repeat what colleague jonathan said but obviously we now know that the suspect is ryan lanza, 20 years old. teacher at the school. sources are telling me that lanza had besides the military style outfit. three guns, a long assault type rifle and two pistols. in terms of the crime, it appears that so far and coming from two different sources and fluid investigation that a lot of the 18 children might have been in the very same classroom. and that it was a classroom that, you know, his mother worked at when they started tracing the addresses back that's when authorities found his mother dead earlier today so they're still processing that crime scene. they're still obviously a lot to do at the school and figure out why 20-year-old ryan lanza would out in such a god awful
