The Parole Board says a convicted double-killer is an angry man, who remains an untreated, violent offender.
The board has issued a full written decision on Malcolm Francis, 64, who was this week denied parole, but legally must be released next year.
Francis stabbed his first wife in 1975 and beat his second wife to death with a frozen dog roll in the 1980s.
He is nearing the end of a sentence of 12 years in prison for the manslaughter of his partner, Wathanak Tea in 2001. Francis denies he did it.
The Parole Board says it has real concerns about Francis because his underlying anger remains apparent, he has no motivation to rehabilitate himself and does not have a robust release plan.
