In 2001, Unsolved Mysteries aired a segment on Jill Behrman, the Indiana cyclist who went missing in 2000. There is a sad update: some human remains were recently found in a wooded area, and they have been positively identified as Jill Behrman's. :(

Here's a link to the article: http://www.theindychannel.com/news/2038843/detail.html

That is really too bad. At least the family can have some closure, though. Thanks for the update.
