A forensic anthropologist, Dr. David Wolf, examined the plaster cast and stated it was probably that of a black slave. Wolf said the cast made by Rev. Fall did not provide enough evidence to be certain, but several clues also point to the conclusion it may not be Daniel Boone. Wolf stated he does not believe the skull shape, slope of the brow, the brow ridges and occipital bone are caucasian. The body removed from Missouri was that of a "large and robust man". According to Boone's brother-in-law Daniel Bryan described Boone as about 5 foot 8 or 9 inches tall. Boone had blonde hair and blue eyes.
