Melony Attwood, 37, and her 22-year-old live-in lover Robert Edhouse, killed her partner Alan Taylor, 42, in April 2016

Two neo-Nazi lovers who bludgeoned the woman's long-term boyfriend to death with a hammer before going to the cinema have been convicted of murder.

Melony Attwood, 37, and her 22-year-old live-in lover Robert Edhouse, savagely killed her partner Alan Taylor, 42, in April 2016.

They took it in turns to beat him with a hammer before changing out of their bloodied clothes and going to see The Jungle Book to create a false alibi.

The pair then went to another neo-Nazi's house where they laughed and joked about the killing and discussed how they would get $1million from Mr Taylor's life insurance.

The next day they went through the 'charade' of calling Triple-0 and reporting Mr Taylor's death.

Paramedics said the helpless victim may have been alive for up to five hours before bleeding.

He was living with Attwood, their three-year-old son and several other people including Edhouse in Perth when he was killed.

Mr Taylor and Attwood had been together for nine years but she had become 'tired' of him and wanted to be with Edhouse instead.

Edhouse was president of the Perth chapter of white supremacist group Aryan Nations and Attwood ran a linked group called Aryan girls.

They were convicted of murder by a WA Supreme Court jury on Monday after a month-long trial.

Another member of the group, Corey Joshua Dymock, 21, was acquitted of murder but was found guilty of being an accessory.

Mr Taylor was found bludgeoned to death in his home in Girrawheen, Perth in 2016. He was living with Attwood, their three-year-old son and several other people including Edhouse when he was killed

All three offenders will face a sentencing hearing in May.

A fourth person, who cannot be identified because he was 17, pleaded guilty to murder and was given a reduced sentence for testifying after his grandmother 'told him to tell the truth.'

Major crime squad Det-Sgt Dean Lampard described the attack against Mr Taylor as 'brutal' with a "high level of violence".'

Aryan Nations is a white supremacist religious organization which was set up in Hayden, Idaho but has chapters around the world.

Richard Girnt Butler founded the group in the 1970s, as an arm of the Christian Identity organization Church of Jesus Christ–Christian.

Edhouse was crusading for the group in the weeks leading up to the murder, reportedly leaving white supremacist messages in letterboxes of Perth homes.

Graffiti tied to the group had also been appearing including an ill-shapen swastika spray-painted onto a Midland carpark.
