On the day after the assassination, at about 5:30 P.M., William Allen Harper,
a student at Texas Christian University, was taking photographs of the Dealey Plaza
area when he discovered a piece of bone near the scene of the assassination.
Harper informed the FBI that he took the bone to his uncle, Dr. Jack C. Harper,
and that they both went to Dr. A.B. Cairns, chief of pathology at Methodist Hospital, Dallas, Texas.
Dr. Cairns believed the bone to be a piece of human skull.
William Harper said he then gave the specimen to Special Agent Anderson of the FBI on November 25.
This bone is now missing.
