I reckon analysing the ransom note is like the medieval poser,
how many angels can fit onto the head of a pin?
Since the ransom note is fake, and that the paper its written on, along with the pen used, was sourced from inside the Ramsay house, also add in the initial drafts or practise versions found, along with the fact that there is
no evidence of an intruder.
Then the most important deduction that follows from the latter is that an occupant of the Ramsey household authored it.
Given the context of the ransom note, why SBTC should mean
Saved By The Cross beats me, not unless the alleged
foreign faction were intended to have a christian background?
Were John and Patsy people of faith, or was their church-going simply a conservative habit?
If Patsy authored that ransom note why construct it to be largely ambiguous but sign off with a contradictory christian phrase?
The purpose of the ransom note is to deceive you, so like any staged crime-scene evidence you cannot use it to speculate about prior events.
But there is one feature worth considering, that is, which information did the Ramsey's want you to beleive?
Well foremost for me is this extract:
I will call you between 8 and 10 am tomorrow to instruct you on delivery.
This along with JonBenet's tombstone inscription is probably intended to give you the false impression that after returning from the White's, JonBenet was killed later that night?
JonBenet may have been killed later into the morning than most people assume!
