In the summer of 1989, a construction crew working in the basement of a building at the Medical College of Georgia in Augusta stumbled across thousands of human bones. The acquisition and disposal of the remains has been kept secret. 

It happens again in 1994, a crew discovered an old well containing human remains while constructing a new medical sciences building on the campus of the Medical College of Virginia (MCV) at Virginia Commonwealth University. The well is called the Limb Pit. 

It happened one more time at Harvard in 1999. During renovations at Harvard’s Holden Chapel in 1999, a worker operating a mini bulldozer stumbled across human remains when his machine broke through a wall into an old well.

Joseph Scott Morgan explains how it's possible to find human bones that have been hacked, cut with a saw, chisel, or knife, and then hidden so the law can't find them.....and it isn't a crime.
