RIDDLE, Ore. (AP) -- A search for a missing worker on the Cycle Oregon bike tour in Douglas County is going into its fourth day.
Bicyclists and other volunteers from Portland planned to travel south Tuesday to help look for 54-year-old Mark Bosworth. He vanished from a bike tour campsite in Riddle over the weekend.
Riddle, south of Roseburg, was the sixth stop in the annual seven-day tour.
The Oregonian (http://bit.ly/pKsnk1 ) reports that friends described Bosworth as not his usual self Friday, appearing confused and sometimes incoherent. The last report of him came from late Friday night. The search began the next morning.
Bosworth is a geographic information system supervisor for the Metro regional government. He has twice been in remission with non-Hodgkin's lymphoma.
