Trio face retrial over Perth mum's death

Three men found guilty of manslaughter over the death of a Perth mother, who jumped or fell out of a moving car after she had been kidnapped, have had their convictions overturned.

Ross James Boag, Leroy Smith and Lucas James Yarran were in March last year found guilty of unlawfully killing Peta Fairhead, 27, in August 2016.

It was alleged at their Supreme Court of WA trial Ms Fairhead and two male acquaintances were lured to a Ridgewood house then robbed, detained against their will and terrorised.

The trio will face a retrial after their appeals against conviction were successful on Thursday.

The trial heard all involved were using methamphetamines.
