A La Porte man who had been missing since Saturday was found dead in a ditch along Interstate 94 Tuesday afternoon.  Indiana State Police say a mowing crew was clearing the grassy area on I-94 about one mile west of the Portage exit when the body of 50-year-old Ricky Kimble was found.  Kimble had been reported missing on Monday and hadn‘t been seen since Saturday.  It‘s not known how Kimble died.  An autopsy is pending at South Bend Memorial Hospital.  Police are still investigating as to what may have caused Kimble‘s death. Anyone who may have seen Kimble walking on I-80/94 from late Saturday until early Tuesday is asked to call the La Porte County Sheriff‘s Office.
