d.n.a. test on a wig worn by the killer which is defense has offered to pay for which could be completed before the execution date that's been refused by the authorities in the state so joining me to discuss this is rather balco senior writer and investigative reporter for the huffington post rather thanks so much for joining us tonight and i guess if you could first just give us a little bit more background here as to this case because of course the wife is also involved the second man that confessed to the murder that allegedly was having an affair with the wife was involved and so when arthur really get into it. from what i've read about the case it's actually not clear why. she rested why he was a suspect. but the you know the really sort of only thing about this is that not only will the state not test the d.n.a. from the wig but there's actually a rape kit and actually the wife claims that they are at the red rate on the night which they committed the murder and then this other guy has now

for the occasion nicholai and victoria were confident the field all was this regardless of any d.n.a. test hundred is still the boy who they raised for eighteen years as if he was their own will always remain dear to the. finish but now i think short as my brother can call him a stranger we go my brother's. you know it is certainly joys that we have found our son of but we have never ever thought of abandoning andree. and i explained to my younger son's got to be two to ever say two hundred that he's not your brother even if you quarrel always remember that he's your brother and love him just like you always have. and if you. did you know. quite recently another boy appeared in the belmont a family nicholai in victoria have now adopted land that was abandoned by his parents. knew. her the warmth of the family fireplace is what unites everyone in this home. in the parent's rests the spark of love for each child. but one who has no child to love is maria she's left all alone in the far northern city of your cook school. that's.

they don't have to do d.n.a. testing. that is crazy nutty. they know who is doing it. all the neighbors know which dogs are running around pooping. >> security cameras. >> in all seriousness, there is a flu running around. >> we have been talking about the dog flu. the first case showed up in baltimore. >> symptoms? >> a really bad cold. and when the dog gets it, it is horrible. you can vaccinate against it. >> just like the human flu shot. not the same, but the same kind of deal. >> yes. >> when we talk about this, we talk about shots for dogs, medical treatment for dogs, and some of the stuff gets sophisticated. >> one thing i want to say, -- >> there's a lot of pet insurance. one is called trupanion. i think it is the best of breeds. in the past it pays up a certain amount. this pays the whole amount minus the deductible. >> it is not zpactly the same as hour health insurance. >> not exactly the same. but it is close. it is a smart, smart product. talk to your vetnarne. i like it. >> who would have thought that we would be working with pets on the air. time for one

but the case went cold until 2009 when the d.n.a. testinged investigators toward this woman, the former detective from los angeles police department. this woman killed the victim because she married the man this woman loved. trace has the news from los angeles. what is the key evidence, trace? >>trace: a bite mark that was never identified and police all along thought it was the bite mark from a man until it said, no, it was from a woman so her colleagues, the detectives followed her around until they found a cup she drank from and they tested the saliva and it was a probably match. her, she is after the colleagues accused her. listen. >> if you claim that i am a suspect, i got a problem with that. okay? so, if you are doing this as an interrogation, you are saying, i'm a suspect, well, now i got a problem, now are accusing me of this? is that what you are saying? >>trace: the recent says the bullets in the victim's body match the type of weapon that she owned back in the 1980's. >>shepard: what is the defense saying? >>trace: the defense sa

d.n.a. testing wasn't even thought of yet. the case went up solved but a quarter century later police say now new testing points to a killer who worked right across the hall. trace gallagher has this story los angeles newsplex this afternoon. this comes down to one big piece of evidence. >> and that piece of evidence, shep, is a bite mark on the victim's arm that police long thought was caused by a man until the d.n.a. lab dropped a bombshell saying no the bite was actually caused by a many would. so then l.a.p.d. detectives began following one of their colleagues, stefanie lazarus. took a cup she bite got a probable match. the prosecutors say the odds of it not be lazarus are one in one sextill i don't know. that's a lot of zeros. >> if you are claiming i'm a suspect. then i have got a problem with that okay? so, you know, if you are doing this as an interrogation, you are saying, hey, i'm a suspect. now i have got a now you are accusing me of this? is that what you are saying? >> by the way i said sextillion that's 17 zeros.

d.n.a. from a human sample or any organism, and we can chop it into little pieces and we can by a series of simple molecular tests deliver those on to this chip and all the really interesting work happens on this chip. >> if you put it in the machine, what happens? >> i simply put the chip in the machine, and i pull this lever down. what we're able to do, the principle is very simple, peter. what happens here, we actually introduce reagents, we introduce nucleatides. there are four agents, a, c, g, and t. what happens is a charged ion is released, essentially a proton. it is the name of the instrument. we are able to measure that charge. by measuring that charge, we can actually determine the sequence. we see the chemistry in real time by measuring that charge. >> so what are the practical applications of this, dr. scott? >> it is primarily biomedical research. one of the things i'd like to point out, the smaller version or kind of an assistance to this is called a personal genome machine. to give you an example of what that is used for, you may recall the e-coli outbreak in europe a few months ago? the personal
