Well, we don't really know for sure. Some say she was in a shallow grave, others say she was buried in leaves.
But they are keeping tight-lipped about it, or don't know much yet. Her remains were scattered over a large area.
I imagine the Smithsonian Forensic's Team can establish from the little "thingies" in her bones if she was buried in dirt...or not.
I can't buy the story the Predator in jail offed poor Chandra. Naahhh.
