We'll have to disagree on that. Show me one other case where an intruder has spent hours in a home. You also have to come up with a viable point of entry, then explain why the Ramseys lied about so many things that morning. That spiderweb still runs across the window, so again the question is HOW DID HE GET IN?
You also have to come up with a suspect that can be gone from their own home and/or family for hours on Christmas. So much for it being someone they knew well and had a key. That suspect would be so easy to identify, just by checking alibi's. Which, BTW, is how the eliminated Santa so quickly. He was with his extended family having Christmas Dinner. Just like at least 95% of the population of Boulder, assuming they had not left town to visit family, also easily verified.
