troubling as they were mysterious no surveillance video or security tape showing anybod doing it >> no, the only common denominator is linda and paul. >> so, linda was getting the treatment and paul was right there by her side as a beautiful husband? >> paul, the dutiful, doting husband. as they reviewed all their interviews and conducted nuance, they picked up on a theme. linda's friends and family didn't much like him her niece, rickie. >> there was this was this arrogance about him. >> remember, paul was physicist. a member of mensa. a jeopardy winner. and apparently he didn't kee any of that a secret >> he was on some other social level than we were so, i felt he looked down hi nose at us >> he thought he was bette than you are >> yes, definitely that. >> but linda of course loved paul's intelligence, and the way he spoiled her but when linda got sick, her friend mary got suspicious >> she was telling me, or paul is now making me the salads an he's making this new dressing. and you know what he's doing mary he's such a good guy, he's drawing a hot bat for me right after i eat. and he's making me so -- and she's getting sick >> and you think that this salads and the homemad dressing and hot bath all ha something to do with it? >> i think he's a nuclea physicists, right? yes he's mensa, he's a smart guy. i think he was trying differen things >> things like nicotine? was that even possible well, not impossible according to toxicologist -- jones. so you could serve somebody spicy or savory enough thi

that they would not know there is a significant enough amount nicotine if you introduce it to someone 's bathwater and put in some perfume or send itself of some kind - >> it may be able to mask an order it may produce so there is a lot of ways that you can get nicotine in your system without noticing it >> possible. >> it's worth remembering that paul got sick at the same time linda did. so whatever affected her, seem to affect him too. but as friends and famil watched poll get well, and linda get sicker, thei suspicions hardened. >> you always immediatel suspected paul having done something? >> yes, from the first phone call >> i thought he definitely was trying to kill

>> other people thought th same thing >> absolutely. >> nobody called the police? >> there was no proof. >> still, mary says, she tried to warn linda. i told her she had to leave. >> and she said what you're seeing things >> she, mary, she's a good he' good husband he wouldn't hurt me. >> those worries from friend and family, and myster illness. and questions about the iv a lot of suspicions. but no evidence. and certainly no witnesses except one >> what's your full name >> linda lee curry curry >> linda curry herself and what she had to say wa breathtaking >> coming up >> how have you've been feeling? since she left the hospital? >> linda's powerful words from the past >> if somebody were trying t do something to you -- if they were trying to poiso you -- any idea who would try to do that >> when dateline continues

headphones on and listen t linda curry's voice. >> i'm hard on a lot of things i'm hard on my man, i'm hard o my cars, i was not easy on m iv bag >> she seemed to be joking about the apparent damage to the ivy, but detectives weren' laughing they knew linda's friends an family suspected paul. >> i'm going on the assumption right now, that paul is doin this, we can't prove something -- >> linda did acknowledge the suspicions of others >> all my friends, a lot of my friends are saying that paul i guilty, get out of the house >> but, she did not suspect he husband. >> i don't really believe that paul tried to do anything. >> she described a lovin partner, who nursed her throug her illness. >> i've got to say that, overall, our relationships

wonderful. he's a wonderful man i love him >> and she seemed to mean it i that interview but in another one, she said something entirely different so different it makes you si up a little straighter >> if somebody were trying t do something to you -- if they were trying to poiso you -- any idea who would try to do that >> well, the only person i could think of that would have the motive to do it would be paul and -- and the only motive i can thin of his money >> for investigators shoal thi was a revelation, she says it' why she stuck with this case for so many years. >> it's very rare to find motive in a homicide, atul, an in this case i had a motive. >> handed to you by the victim >> yes when i listen to that interview,

i thought this is unsolvable case >> you thought she laid it out for us, we should finish it. >> from the grave, we have t find justice >> they began to follow th money, it turned out linda was worth a lot of it. she had a retirement account a edison and almost $700,000 i life insurance and, despite her reluctance to believe that paul was trying t poison her, she had change those insurance policies making her sister -- according to the prosecution paul only found that out after linda's death, and he wasn't happy. >> he had letters that he sent to the insurance company sayin that we paid for the premium from our marriage money, i a entitled to it >> he also find out that pau had filed an insurance claim for a ladies rolex wall watc and some jewelry that had gone missing after linda's funeral. he received a 9000 dolla payout but investigator knew that

linda had wanted the rolex t go to her sister >> and i called her and said there is a report that the watch was stolen, she says no have to watch on right now >> in fact, the watch had neve been stolen. paul curry, it seemed, had filed a phony insurance claim. >> who does that if somebody is an innocent spouse, grieving the death o his beloved wife, who decides, within days after that to fake the theft of her rolex and fil a claim to collect the money >> paul, apparently. but it turned out that h needed bother, linda's conflicted feelings about paul ran deep five months after taking him off her insurance policies, sh wrote her sister pat a letter, a will and left paul $400, 000 which eventually received afte her death. but by then, paul had othe

troubles within a year of linda's death paul's boss mike flower, discovered that his storm ploy was not a nuclear physicist. as he had claimed publicly and on his resume for so long. >> he didn't have a degree a all, paul ended up submittin his resignation. >> and if he had not, he would've been fired? >> yes >> to lie about something that could be so easily checked that says to me that the perso doing that has an unbelievably large ego. >> it was very disappointing >> so would, he thinks he ca get away with everything >> it was very disappointing >> all of it added up to a deeply unflattering portrait o paul curry, but did it add u to a case for murder this prosecutor knew that it did not. he and the detective face th

same problem that th detectives face in 1994, lot of suspicion, but no direc evidence that paul kille linda. and they felt that the current suspect, a self proclaimed genius knew that >> he was smart enough t realize that any police officer, the minute after she was murdered is going to expect th husband to be the suspect. he was one step ahead. >> his theory, paul tested different poisons, carefully picked an obscure one, the poisoned himself, to cover his tracks >> the first time linda go sick, he had the exact sam symptoms, because that allow him to say both -- we both got sick, maybe we bot got something. >> you think that's hi thinking ahead >> sure that's his mo. he went back to the night lind

died and the nicotine that killed her, he consulted a nicotine expert who had looked into the case back in 1994 >> i remember the case, nobody ever followed up with me i go would you kindly, please, be willing to write a report about your interpretation of the results? >> it turned out to be the breakthrough they needed the amount of nicotine in he blood was extraordinarily high nearly 100 times would you would find in a regular smoker forensic toxicologist. >> for the amount that was found in those specimens i could take a matter of minutes to reach death >> and remember, paul ha always maintained he was alone with lynda four hours before she died >> that report allowed us to say look, it is absolutely categorical no other human being that had the opportunity to do what he did. >> prosecutor and th investigator knew it was now time for some show intel wit paul curry coming up. paul curry had something t reveal >> i have -- i have been less than honest about that >> when dateline continues or, like being over 65,
