Search for cyclist continues

and local sources

ROSEBURG — The search for a missing Portland cyclist last known to be in Riddle continues this week as family and friends encourage members of the public to spread the word via social networking.

Mark Bosworth, 54, is a volunteer with Cycle Oregon who appeared confused before disappearing on Sept. 16 during the tour's stop in Riddle.

Bosworth is a two-time cancer survivor who may be suffering from a recurrence of the disease. In a Monday press conference, family members say he had been forgetful and complained of headaches before departing on the week-long Cycle Oregon excursion as a volunteer. They said he had made appointments with doctors, but had scheduled them for after the ride.

Bosworth's wife, Julie, and two daughters have returned to Portland after helping search in the Riddle area for more than a week. Other family members are staying in Douglas County to be close to the investigation.

About 2,000 riders participated in the Cycle Oregon event, which began and ended in Sutherlin, looping northwest to Reedsport then south to Bandon before turning inland to Riddle and back to the starting point.

After Bosworth was reported missing, investigators and family members pieced together details suggesting that he was suffering from a brain disorder, likely related to a cancer that had been in remission.

Two days before he went missing, he fell asleep in Bandon in a pizza delivery car, until its owner woke him up. He didn't remember where he had set up his tent the night he went missing from Cycle Oregon. Two days earlier, he told his wife in a phone call that he was on the East Coast, then said he was in Canada.

He later told his wife he was describing a dream to her. Family members said in the press conference that it appeared he was trying to cover up the symptoms so he could finish the event.

Online and social media efforts are being utilized to help spread the word about Bosworth's disappearance. A Facebook page has been set up at www.facebook.com/FindMarkBosworth. A Twitter account can be found at @FindMarkB with posts under the hashtag #findmarkbosworth. A website also has current information at www.FindMark.org.

A $10,000 reward is being offered by Deckers Outdoor Corporation, Julie Bosworth's employer, for information directly resulting in locating Bosworth. The Douglas County Sheriff's Office tip line is 541-957-2099.

Cycle Oregon officials said Bosworth at first drove a truck for the event but was later was given a different assignment. Other participants said they noticed that he was having trouble following signs on the one day he rode the route, and had failed to show up for his volunteer shifts.

Bosworth was last seen after 11 p.m. Sept. 16 at his campsite near the Riddle High School baseball diamond. He left his bicycle in the Cycle Oregon camp.

Authorities have found no traces of Bosworth. He did not have a wallet with him when he disappeared, but may have had cash. No activity had been reported on his cell phone.
