remember, another part of their investigation involved this basic question. was cari farver alive or dead? >> her father died. >> reporter: yeah. >> and she didn't go to the funeral. missed her son's birthday. all these things. i mean, it didn't take ryan very long at all to come to a dead end where he -- he couldn't find anything to show that -- >> no. >> -- she was alive. >> reporter: suddenly cari farver looked not like a villain but like the real victim. and the woman who claimed she was the victim -- liz golyar -- looked like the prime suspect in cari's disappearance. because, why else would you disguise yourself as cari if you weren't responsible for it? why would you be in cari's vehicle if you weren't responsible for it?
