The Prisoners Review Board has completed its inquiry into whether convicted Greenough axe murderer William Patrick Mitchell should be granted parole after 20 years in jail.
The Board expects to present its recommendations to Attorney General Michael Mischin early next week.
Mitchell, 44, was convicted of murdering a family of four at their home while high on a cocktail of drugs in February 1993.
Karen McKenzie and her children, Katrina, 5, Amara, 7, and Danny, 16, died when Mitchell attacked them and sexually assaulted Ms McKenzie and Amara.
Details of the frenzy were suppressed, deemed too horrific to be disclosed.
A petition calling for Mitchell never to be released was presented to Parliament in June by Geraldton MLA Ian Blayney.
Mr Blayney also wrote to the Premier and Mr Mischin to alert them to the depth of public anger stirred up by the news that Mitchell’s case would come up for review this Sunday, October 13.
The chairman of the Prisoner’s Review Board, Judge Robert Cock QC, said the board was required to provide a report to the Attorney General on or after Mitchell’s statutory report date.
His case had been reviewed every three years.Mitchell’s original sentence of an indefinite term was overturned in 1996, making him eligible for parole this year.
