The famous signature of the JonBenet Ramsey ransom note. Recently it has been purported to be an acronym for Shall Be The Conquerer. This was brought to light when John Mark Karr claimed he was the one to write the note. A school yearbook belonging to Karr 's former female classmate may provide the link between Karr, the yearbook, and the Ramsey ransom note. In the yearbook, Karr ended his signature with the line, "Though, deep in the future, maybe I Shall Be The Conqueror and live in multiple peace." The words in initial-capitalized letters do not appear anywhere in the yearbook as an acronym.
John Mark Karr is just some kiddie porn addicted perv trying to get his 15 minutes of fame.
I S.B.T.C. in telling this man he is a complete dipshit.
