PER FOX:
Karr's exwife claims to have the letters with STBC on them.
If she actually has those letters that would be something!
SBTC
You have the T & B reversed.
No matter, I've mixed them up myself at times.
"Shall Be The Conqueror"
Do tell. (The ex has some of them?...the plot thickens.)
Oops...
I might be taking that wrong, the bold print at the bottom of the screen on FOX reads:
KARR'S EX-WIFE CLAIMS TO HAVE LETTERS SIGNED "SBTC"
SBTC? Have they shown them anywhere yet?
