FBI Joins Hunt for Missing Colorado Girl $10K reward in case of girl who vanished on way to birthday party By Jane Yager, Newser Staff Posted Apr 7, 2010 6:04 AM CDT 3 comments Comments This undated photo provided by the National Center for Missing and Exploited Children shows Kayleah Wilson. (AP Photo/National Center for Missing and Exploited Children) (Newser) – The FBI has joined the case of a Colorado girl who vanished last week while walking to a friend's birthday party. Kayleah Wilson, 12, disappeared during a nine-block walk to her friend's house in Greeley, Colo. Police and FBI are now scouring the region on horseback, in all-terrain vehicles, with search dogs and by airplane, and hope a $10,000 reward will help solve the mystery. "It could be a runaway. It could be an abduction. Right now, we don't have anything to rule out," authorities told CNN. A police spokesman said the case had eerie similarities to the disappearance about 25 years ago of another Greeley girl around the same age, who vanished from her house. That case was never solved.
