"It’s around 6:30. I haven't heard from you,” he said in the message. "Maybe you're out of the country or something. Anyway, give me a call if you get this message. Bye."

For 15 years, Condit has refused to say if he had an affair with Levy.

The voicemails, obtained by ABC’s 20/20, seem to confirm what many have long believed — that Condit and Levy were more than just friends.

"Give me a rundown on kind of what your schedule is. Things are looking pretty good for me today anyway. Bye,” he said in another message.

Condit was cleared as a suspect in her murder. An undocumented immigrant from El Salvador was later found guilty, but that conviction was later overturned.

The 20/20 investigation airs Friday night.
