tried to contact him after she disappeared. i thought she was going to page me on friday. she goes somewhere, and she never paged me on friday. we know that cathy s mom paged him 20 or 25 times in a matter of at least a couple of days, trying to get him to contact her because he s so close to cathy and she s missing. reporter: montgomery noted a key detail about those pages. mary s home phone and cathy s home phone are the same number. they re the same numbers. reporter: so, seeing that number on his pager, how did sam know it wasn t cathy? if he knew she was alive, he would know he got 20 or 25 pages from cathy, or at least think that. if he s guilty and he killed cathy, he knows those 20 or 25 pages were not from cathy. reporter: that was tell number two. then montgomery noticed how, in his second interview, sam referred to cathy s murder. you know? but then this happened and shoot. he doesn t use the word
correct. reporter: and where was he? he was in state prison. reporter: so whatever s going on with this guy, he s not your guy. he well, he s not personally. but is he related to does he know? what s the connection? why is this stuff in the trunk of his car? reporter: when you say to him, why would you have articles about cathy torrez s murder and receipts from sav-on in the trunk of your car, his answer s what? that s all my wife s stuff. he disowns it. he separates himself from it, which now raises a little bit more suspicion. reporter: could you tell if he was connected to anyone in the case? not initially. i really had to dig a little bit deeper to see what the connection was. reporter: daron finally located the convict s wife. she was uncooperative at first, which again, now, this is raising suspicions again. ultimately she did come in and talk to us, and her explanation was that she went to valencia high school with cathy. and then upon closer examin
officers opened it, and cathy torrez was missing no longer. she had been stabbed multiple times. all about the upper chest and neck. reporter: detective sergeant daron wyatt. you know, there s no way to time the death. but i think it s pretty safe to assume that she had been dead since she disappeared on that saturday night on the 12th. reporter: it was devastating not just for the torrez family but for all those in placentia who d been searching so tirelessly for cathy. she was a vibrant, very intelligent young girl. this is truly a tragedy. reporter: detectives went to work trying to find cathy s killer. they set up a hotline. if you have any information regarding the homicide of cathy torrez reporter: and scoured placentia for clues. by studying her car and her body, investigators got a sense of what happened. first, cathy was completely clothed. no sign of a sexual assault.
