A Sunday morning crash involving four vehicles caused minor injuries to four Bend residents just before noon…and slowed traffic on Hwy 20 at Hamby Road for 30 minutes.  Deschutes County Sheriff’s deputies report that a car driven by 50-year-old Andrew Hager was southbound on Hamby Road and attempted to cross the intersection in the path of a vehicle operated by 59-year-old Mark Johnson.  Johnson swerved to avoid the collision and collided head-on into a vehicle operated by 76-year-old Rita Harris.  They then both struck a fourth vehicle driven by 25-year-old Mami Whitsett.  Amazingly, all four drivers where checked by paramedics at the scene and were released.  Harris was later evaluated at a hospital.
