cher hughes had been missing for two months. ered if her disappearance had anything to do with another american who'd left the islands abruptly four months before cher, a man named bo icelar. bo was quiet, you know, introvert. he was a really great guy. kate snow (voiceover): bo kept a low profile since moving to bocas from santa fe, new mexico in 2004. the former antique dealer was so quiet that no one really noticed when he took off. a lot of people say, let's go to argentina for six weeks. get on a boat and go. so they don't necessarily email everybody and tell them they're leaving. so it's pretty easy to be not missed for a while. kate snow (voiceover): it made even more sense when they found out that bo had sold his home to wild bill, another american in their group famous for throwing lively parties many of the expats attended, including cher's friend, kristen. i knew that he wanted to sell and move somewhere different. and so i assumed that they'd come to an understanding over the price and that bo had just left. kate snow
