The body of a missing Colfax man has been recovered from the Des Moines River in northwestern Marion County.  The Marion County Sheriff’s Office says the body of 34-year-old Dustin Dittmer was found shortly before 7am Saturday (5/14) upstream from the Bennington Boat Ramp.  Dittmer and two others were on an airboat on May 7, trying to help two men in another boat get to the boat ramp.  The airboat capsized, sending Dittmer and the two others into the water.  A man and woman made it back to shore, but Dittmer did not.
