"JonBenét Patricia Ramsey (/ˌdʒɒnbəˈneɪ pəˈtrɪʃə ˈræmzi/; August 6, 1990 – December 25 or 26, 1996) was an American child beauty queen who was killed in her family's home in Boulder, Colorado."
Here's a conspiracy- she was killed by a neighbor and her parents set up everything like the place, clean up, staged 911 call, and ransom note. The neighbor was paid tremendously for their silence.
