Bradley Murdoch's wedding anniversary was the 14th of July.
From Paul Tooheys book - the killer within
The only time Brad Murdoch ever decked his wife Dianne was just before she left him. It was a good one, right above the eye. But he was never weird. No bent sex, nothing like that. He never forced himself on her. Dianne met Brad when she was ten. It was at her Aunty Pamela’s wedding to Murdoch’s older brother, Gary. She never spoke to Brad then; she never really spoke to him for another ten years. Then in 1980, when Dianne was twenty-one, she was visiting Aunty Pam when Brad turned up, with manners. He was neat and tidy. She liked that. In the next year she started seeing him, moving up from Mandurah, 75 kilometres south of Perth, to live with him on the city’s outskirts. They started a trucking business, Brad an owner-driver subcontracting to bigger companies. They were declared bankrupt in 1983 and married in 1984. She couldn’t remember the date. They didn’t ever do wedding anniversaries. They didn’t do much, in fact. Brad was always away, driving, hauling. A son was born in 1986. The relationship was over by then. They passed as strangers in the small rooms of their home. She didn’t like the drunken parties. She didn’t like how Brad couldn’t seem to stick to one task. She left when their son was around eighteen months old, taking the boy and that punch with her. The boy grew up never knowing his dad. No maintenance was ever paid. Dianne didn’t know the date of her own wedding but the records can assist. It was 14 July. Exactly the same day, seventeen years later, that Murdoch went looking to steal himself a woman off a Northern Territory highway. He ended up losing her, too
I have not been able to locate records that can confirm or dispel this report, so at this stage I can only regard it as an unconfirmed rumour.
It is known that Mr Murdoch blamed many of his misfortunes on the failure of his previous marriage and that the church was to blame, his ex wife Dianne became too involved in religion and this placed a wedge between them. He was very bitter about this and no doubt his wedding anniversary would not have been a date he celebrated
If it could be proven that his wedding date was the 14th of July it would then become yet another piece of circumstantial evidence, one that would stand as a strange coincidence that may or may not had some bearing on the events of that night at Barrow Creek.
