In an interview with the Colorado City Record, Detective Kelsey Alexander of the Colorado City Police Department said rumors slow the investigation by forcing officers to confirm or discredit information.
Alexander said one recent example was a Facebook page claiming that someone had Hailey and offered to trade her for passage to America. Colorado City Police worked with Facebook to shut down the page.
"Facebook is public enemy #1 because it is a site of gossip and internet bullying from one person to the next," Alexander told the Colorado City Record. "People take what they see on Facebook as real."
"We haven't heard anything on Facebook that's brought us any closer to Hailey," Alexander added.
Dunn has been missing since December 2010. The only named suspect in the case has moved out of the area. He was never arrested.
