The CBS 'documentary' was a total sham that was not a "complete re-investigation", but a a pre-determined 'investigation' based on Kolar's book and everything that followed was twisting, stretching, ignoring, explaining away and even inventing 'evidence' to point in that direction.
The 'climax' of this theory is that Burke bashed JBR's head in because she took a piece of his pineapple* meal.
Utter nonsense.
There is no evidence whatsoever that Burke Ramsey killed JBR. None.
*According to Paula Woodward (who had access to the "Murder Book Index," a 3,000-page summary of files and reports on the case and an unpublished 1,000-page Boulder Police Department file of its officers' involvement in the case) in We Have Your Daughter: The Unsolved Murder of JonBenet Ramsey Twenty Years Later, the pineapple was probably part of a fruit cocktail that JBR ate:
According to previously unreleased BPD reports, laboratory testing revealed that JonBenét also ate cherries and grapes as well as pineapple. Remnants of cherries were found in the stomach/ proximal area of her small intestine. “Another item besides pineapple was cherries.” (BPD Report #1-1348.) In that same report: “Another item besides pineapple was grapes.” (BPD Report #1-1348.) Another report expands on the grapes, saying “grapes including skin and pulp.” (BPD Report #1-349.) The food described resembles what is included in most cans of fruit cocktail.
