John Mark Karr & the Jon Benet Ransom Note
August 25, 2006
My name is Treyce d’Gabriel and I am a Forensic Handwriting Expert with over 20 years of international experience. Therefore it is my professional opinion that John Mark Karr did not write the Jon Benet ransom note.
In examining the handwriting of both Karr (yearbook) and the note itself, I find that the writings are not alike and that there is no way for Karr to have been the author of said ransom note.
Below are the side-by-side comparisons of every alphabet letter (except Q, X and Z). I have removed my written descriptions in order to save on file size; my findings are visually obvious.

More obvious differences include, but are not limited to, pressure, slant, baseline, and spacing.
To reiterate, based on my professional opinion, John Mark Karr is not the author of the Jon Benet Ramsey ransom note.
