Mrs Reaney told Hawke's Bay Today in 2004, "If a life sentence meant a true-life sentence without parole we would not have to be going through this yet again - Roma continues to haunt us and destroy our ability to move on.
"We tried desperately for him not to be released," she said at that time, adding she was "sickened" when told Roma had reoffended.
It was about daybreak on the Sunday of April 14, 1991, when Roma burgled the two-storey Reaney family home on Madeira Steps overlooking St John's Cathedral and attacked Simon and his 11-year-old brother Michael.
Simon was bludgeoned with a car jack Roma had taken from a workshop, and died in hospital two days later. Michael was severely injured and was on life support in hospital for a fortnight.
The boys' father, accountant and former Otago and Hawke's Bay rugby representative Stephen Reaney, was also attacked as he confronted the naked and chanting intruder while his wife protected their infant daughter.
Released a fortnight ago, Roma botched his previous release in 2003, being recalled after only a short time for an indecent act in a Manukau shopping mall.
Soon after Roma's indecent act sentencing in 2004, the trust launched a campaign which led to the Three Strikes Legislation.
Among conditions of parole of his new release, Roma is barred from consuming alcohol or drugs, has a 10pm-6am curfew, must undertake assessment and treatment as directed, and live with what the Parole Board regards as a "firm" ex-military man Roma has known since childhood.
The board said it was an "excellent release proposal" offsetting assessments that Roma was a medium to high risk of sexual reoffending, and a medium risk of other offending.
Roma had parole turned down last year, but soon afterwards began a controlled release-to-work programme. While in custody he had in the last year been housed in a self-care unit, with escorted shopping trips and occasional home leave.
An earlier decision to release him in November was revoked after the sponsor's family expressed concern Roma would have been free at the time of a wedding in the family.
After the 1991 attack, Roma fled Napier but was apprehended a week later in a farm paddock in Central Hawke's Bay, half-naked, chanting and brandishing a furry black toy duck as if it were a voodoo doll.
At his trial in the High Court in Wellington, Roma denied a charge of murder, the jury being told of his drug-induced psychosis and claims he had heard voices exhorting him to "kill a pakeha".
He had told a psychiatrist he believed he was a Maori warrior and had to kill, but the jury rejected an insanity plea.
Granting the new release, the Parole Board said Roma had made "huge changes in his life".
While his crime was appalling and the Reaneys remained devastated, Roma had credibly expressed remorse for what he had done, the board said. It believed Roma now had an "insight into his own offending and behaviour and an openness about him which was never previously the case".
