There have been recent reports of selling body parts from morgues.  Apparently this is an old-fashioned money making opportunity.  Remember the Burke-Hare trials in merry old England?  

These two busybodies were exhuming bodies for sale to medical schools, which needed a continuous flow of corpses for anatomy dissection courses.  

When Burke and Hare ran out of bodies below the ground to unearth they used more inventive means on the living to provide more corpses in the interest of medical research.  

There have been instances of exhuming bodies to discover valuables buried with the dead.
