If we look at how JB was place in the wine cellar, This could be a clue.
Most grave yards place the body of love ones in a East West position.
This was a belief that the body will rise after death and the first thing you would see is the rising of Christ. Sun rise is in the East. Sun set in the West like the end of life.
JB feet pointed toward the cellar door or North/West.
Draw a line from the starting point to across the USA and stop at the end of land. As the ransom note stated, Foreign Faction or Canada.
The ransom note used words like Victory and Attaché case. These are words with a French background.
The line from Boulder to this North/West place is known as the Southern Border Tip of Canada or S.B.T.C.
The town is called Victoria CA and is a French word for VICTORY like printed in the ransom note. The word Attache is a common French word use there.
Now take a look at the letters S.B.T.C. and one may say it was on the table. If so, what does this mean.
There was a bowl of fresh pineapple on the glass table, in the bowl was a Sliver spoon. Silver spoons will tarnish with pineapple, not a good choice.
The drinking cup was used for hot tea. A tea bag was place in the glass drinking cup. Odd.
Was this a clue left by the killer?
