Still no sign of missing Portland cyclist

The search continues for a missing Portland cyclist last known to be in Riddle. Family and friends of 54-year old Mark Bosworth are encouraging members of the public to spread the word of the search via social networking.

Bosworth, a two-time cancer survivor who is a volunteer with Cycle Oregon was said to have appeared confused before he disappeared on September 16 during the tour’s stop in Riddle. In a press conference family members said he had been forgetful and complaining of headaches during the week-long cycle trip.

No trace of Bosworth has been found. He did not have a wallet with him when he disappeared, and no activity has been reported on his cell phone.
