Two Marceline teenagers were injured in a one-vehicle accident Wednesday afternoon in Linn County.  The Missouri Highway Patrol says a vehicle driven by 18-year old Thomas Goosey was west on Julep Road, when the vehicle ran off the left side of the road, struck a fence post and overturned.  Goosey was not injured, but two passengers, 16-year old Jonathon Flores and 16-year old Jesse Gauthier, both of Marceline, suffered moderate injuries.  They were both taken to Pershing Memorial Hospital for treatment.  The accident happened around 4:50 p.m. two miles west of Marceline.
