After serving nine months of his jail term and having his conviction overturned on appeal, Brian was released from jail but died in a light aircraft crash on 27 February 1986, when the twin-engined Aero Commander he was flying ran out of fuel near Canning Dam on the outskirts of Perth. Whilst in prison, Ray and Peter embarked on a series of seven appeals against their convictions, essentially on the grounds that their confessions had been fabricated by police investigators. Ray and Peter served eight and six years of their sentences respectively before being released on parole.
