Jason Simpson theory
Another theory was that Simpson's son, Jason Simpson, committed the murders. This is the central theory of a book by Private Investigator William Dear titled O.J. is Guilty, But Not of Murder (ISBN 0-9702058-0-5). Published in 2000, the book was the result of a six-year investigation by Dear. He attempted to explain Simpson's incriminating behavior and the incriminating evidence. In the book, Dear claimed numerous elements to support his theory.
The book is also the basis of a documentary film, including new evidence, entitled The Overlooked Suspect, released in late 2007. Dear hopes the film will finally persuade Los Angeles County to call a grand jury and indict Jason Simpson.
He reveals that Jason had a history of violent outbursts, including attacking people with a knife and had a criminal record.
