she come home and told me that she thought somethin' was gonna physically happen to her. >> reporter: but was toby's theory something else? maybe an attempt to throw the cops off his trail? remember toby said he'd been asleep at dana's apartment, near the scene that night and he was known to have had a turbulent relationship with her. >> there were a lot of people pointing fingers at toby over the years. >> if you went down to the diner and asked, "what happened to dana," a lotta people woulda told ya, "toby killed her." >> that is correct. >> reporter: but dana's best friend, roxy, who'd been partying with her at the nightclub had another lead for investigators -- another name. >> so, what is roxy's story? it's been a festive night, a lotta drink. are either one of them wobbly? i mean, can they handle themselves leaving the club? >> according to what roxy has told us, that dana was pretty intoxicated, that she was not really steady on her feet. >> reporter: and the friends had no way to get home. they'd missed the last bus. the club's bouncer agreed to give them a lift. >> is he a friend of roxy's or a friend of dana's or how's that go together?
