The CBS documentary on this was so good. They had some of the best crime investigators in the world to trawl through evidence for months. They even recreated the Ramsay's basement in order to reenact someone crawling through (which they found was not possible). It was fascinating to see such in depth analysis of a case and the conclusion they came to based on all the evidence (I won't spoil it for anyone who hasn't seen it).
But based on how good that documentary was, I'm willing to believe their theory.
