The unnamed, century-old graves present a problem for the university, whose expansion plans could be halted over the cost of relocating the bodies.
Dr. James Keeton, dean of the medical school, said that moving the remains to a new burial site would cost an estimated $3 million -- that's $3,000 per body.
"We can't afford that," Keeton said, according to USA Today.
Instead of moving the bodies, the expansion will most likely be relocated to another location on the 164-acre campus. It's possible there could be more unmarked graves belonging to tuberculosis patients, former slaves or possibly even Civil War dead, according to the Clarion-Ledger.
