You'll want to read "The Cross Country Killer: The Glen Rogers Story" by Claude Rogers, Jr. and police consultant Joyce Spizer. published in March, 2009. They do not believe OJ Simpson was involved in any way, that he stumbled on the murder scene and panicked. They cite evidence at the scene that was dismissed by prosecutors because it did not support OJ as the killer and raised questions they couldn't answer. It's an insightful read.
