and he hit her in the head with with a club. what happened? he hit her in the head? with a club, golf club. he said he didn t mean to kill her. it just happened, and he got scared and ran and so put her in the pool and then ran. reporter: in a largely circumstantial case, here was an account of exactly what happened, allegedly, from the killer himself. a defendant with any sense, going to tell somebody what happened when he hasn t gone on trial yet? they do it all the time. if they had any sense they wouldn t be defendants. well, i suppose there s that. you got nothing to do all day but stare at those four walls. i mean, you got to talk to somebody, right? yeah. if it s a piece of evidence, i m going to put it on, and it s going to be up to the jury to decide whether he s credible or not. reporter: it was up to investigator newlin to vet dale folsom s story, find evidence it was actually true. and he came up with something, came up with something almost too good to
well, folsom never did make it to the house. so newlin got a search warrant, and went for a little look-around. i went into the master bedroom, and there s this golf club just sitting in the corner, and part of me laughed inside. bingo. yeah, bingo. it must ve looked like a beautiful, big, fat piece of evidence that would help make the case into a slam dunk. i literally looked at it for a minute. i was like, seriously? when i actually went up to the golf club and photographed it, and collected it, there was cobwebs on it. it had been there for a little while. i mean, it wasn t overnight. reporter: this was one for the books; a jailhouse snitch supported by actual evidence, and cappleman had one more surprise. she called crime lab analyst and dna expert jo ellen brown. i received or was able to develop a complete dna profile from the club portion that hits the ball, and that dna profile
to take care of something. something in his house. i ll never forget dale telling me. he said adam told him to get rid of the golf clubs any way, anyhow. throw them in a lake, throw them in a river. do not give them to anyone. just make them go away. reporter: make them go away. folsom said there was no mistaking that frasch meant that he wanted him to get rid of those golf clubs, which would include, of course, the one frasch said he used to hit samira, the murder weapon. did he tell you a specific golf club that needed to be gotten? yes, ma am. a big club like a driver, big, fat one. reporter: and now in court, a real life perry mason moment. this is state s exhibit 121. reporter: investigator newlin took a big fat golf club out of an evidence box so the jury could have a good look. this is the golf club. the one with the purple club head? yes, ma am. reporter: how did newlin get that club?
with her. only thing i do is meet adam once a month, pick my money up, and we go. and so she did. police let her go after the interview. like the other women, she had an alibi. which detectives would have to check out of course. but in the meantime, they had another way to get at the truth. one a bit more fool-proof. we had an unknown dna on a robe that came off the victim in the pool. reporter: samira s leopard print robe. if one of those women had thrown samira into the pool, she may have left a little of herself behind. newlin got dna samples from the women. we tried to eliminate all of them. reporter: no matches. not to the women. and not to the handyman. or his son. and not to adam s friend kendall. all of them were cleared. investigators couldn t figure out who the woman in the driveway was. now they were back to square one. and they figured adam frasch was
the living room. when you say made love, you had sex? i don t like to get into that personal kind of stuff. because it was one of the better times and we have had in a while. then adam told him that samira had told him that she needed a favor. she said that she was exhausted she asked tomorrow just want to break, just take the babies, you guys go somewhere. i want to sleep in. so, come morning, said adam, he took the girls to the beach house. what time was it that you left? it was approximately eight or so. and where was sam? she was in bed. the surveillance camera backed up adams story, there is his car leaving golden eagle, but what struck the cops conducting the interview was how the doctors emotions seemed, how to put it, disconnected from his tear ducks. investigator jason newlin
