Source: A part-time Bend resident died Sunday after sustaining injuries in a bicycle crash in Roseburg. Mark Kitzman, 55, who has been a part-time resident of Bend since 1975, was riding downhill on a bike path in Roseburg’s Stewart park when the front tire of his mountain bike came off. Kitzman was thrown onto the pavement, where he hit his head and severely injured his neck. Roseburg Police Sgt. Aaron Dunbar said Kitzman was on his way to a concert in the park. Dunbar said a mechanical failure caused the front wheel to come off. Kitzman was not wearing a helmet. Kitzman graduated from Roseburg High School, and came to Bend in 1975 after graduating.
