right, yeah. it wouldn t have surprised me that, oh mary, i went sailing and then my phone fell off the deck when i dropped my purse. that would be cher for three to four days. reporter: the messages were reassuring, but not for long. a few days passed, and cher didn t return. then another text message this one from cher to keith. she just said i met somebody else who s better than you, yeah. she said she had met someone else? yes. and she was running away with that person? yeah. reporter: a mystery man? keith wanted to get to the bottom of it. i called her best friend, and said did cher meet somebody? does she have a man that i don t know about? is there something going on? she said she s never mentioned any guy to me ever. she s waiting for you. there s no man in her life. she didn t run away. reporter: but keith noticed something strange about the messages. they weren t written in cher s usual style. instead of small letters, it d be all capitals.
