exhumination
What unfeeling/opportunistic physicians used to do with recently-buried humans --- i.e., illegally remove said fresh corpses from their graves to use for dissection and other medical research.
In "The Adventured Of Tom Sawyer", Doc Robinson is presented as a young naive medical practitioner who was overly trusting of others; had he had an ounce of savvy or common sense, he would have known better than to enlist the help of the town drunk and a known career-criminal in his shady exhuminations.
