To this day, no conclusive evidence has been found to support his theory.

In November 1981, actress Natalie Wood drowned during a boat trip with her husband, Robert Wagner, and co-star Christopher Walken.

Decades later, Wagner was officially listed as a suspect, but the case was never definitively resolved.

Actor George Reeves, known for his role as Superman, was found dead in his Beverly Hills home in 1959; his death was officially ruled a suicide.

His fiancée, Leonore Lemmon, also came under scrutiny. However, the case was never reopened.
