Attwood, who along with Edhouse was convicted of murdering Mr Taylor in his Girrawheen home in 2016, has also lodged her own appeal against her murder conviction.

Attwood and Edhouse, along with Corey Joshua Dymock, stood trial in the WA Supreme Court earlier this year accused of bludgeoning 42-year-old Mr Taylor to death.

Attwood, 37, and Edhouse, 22, were both found guilty of murder following a four-week trial.
