On June 17, 1991 Taylor’s remains were exhumed from the vault at the Zachary Taylor National Cemetery, in Louisville, KY. The remains were then transported to the Office of the Kentucky Chief Medical Examiner, Dr. George Nichols. Nichols, joined by Dr. William Maples, a forensic anthropologist at the University of Florida in Gainesville, Florida, removed the top of the lead coffin liner to reveal remarkably well preserved human remains that were immediately recognizable as those of President Taylor. Radiological studies were conducted of the remains before small samples of hair, fingernail and other tissues were removed. Thomas Secoy of the Department of Veterans Affairs (and a direct descendant of Taylor’s Democratic presidential opponent Lewis Cbum), ensured that only those samples required for testing were removed and that the coffin was resealed. The remains were then returned to the cemetery and received appropriate honors at reinterment. The samples were sent to Oak Ridge National Laboratory, where neutron activation analysis revealed traces of arsenic at levels less than one one-hundredth of the level expected in a death by poisoning.
