Glen Sabre Valance (born Graham Paul Fraser;[1] 11 February 1943 – 24 November 1964) was an Australian murderer.

[2] According to Valance's stepsister, Lillian Clavell, he suffered physical and sexual abuse from his mother and boys' homes and orphanages.

[3] In 2010, she published a book titled A Tormented Soul, in which she wrote about Valance's life, saying his upbringing had created an angry young man.

The final straw for Valance came weeks before the murder, when Strang read his private diary aloud, amusing the other workers.

[4] In the early hours of 16 June 1964, Valance, armed with a rifle, tied up three station hands at the Koonroon property near Bordertown, South Australia then entered the bedroom of Richard and Suzanne Strang.

Valance pleaded insanity, but was found guilty of murder and sentenced to death by South Australian State Chief Justice Sir Mellis Napier on 17 September 1964.
