William Mose Gurule, 57, disappeared after a canoeing accident on the Colorado River believed to have occurred around early November 2010. His last known residence was Meadview, Arizona, but initial reports came from Las Vegas, Nevada, creating uncertainty in the timeline. Accounts say he fell overboard and was swept away by strong currents; he was never seen again and his body has not been recovered.

The remote, rugged river environment and lack of witnesses have complicated search efforts and the investigation led by the Las Vegas Metropolitan Police Department. There are unanswered questions about the circumstances of the outing and the sequence of events that morning.

Does anyone who knew William or who was on the Colorado River that week have information that could help explain what happened?
