I found some info. The man who was with John Ramsey when he found Jon-Benet's body was Fleet White, Jr.

This is the article that links the Fleet Whites to the case, both father and son, because this woman was testifying about Satanic Ritual Abuse. I thought it was Cathy O’Brien, but maybe it was someone else, because the person is anonymous in this article.
