(Hubbard, OR)  --  Marion County sheriff's deputies say there could be more bodies inside a burned-out home in the community of Hubbard.  Officials say one body had been found in the ruins of the home, located in the 18-thousand block of Forbert Road, after yesterday morning's fire.  The sheriff's office says the home belongs to 39-year-old Erin Kroeker and 42-year-old Keith Kroeker, who live there with their three children, a seven-year-old and ten-year-old twins.  Authorities say the body that was found hasn't yet been recovered because what's left of the house is unstable.
