Helen Milner, the woman dubbed the Black Widow, has lost
her appeal against her conviction for murdering her husband.
The Court of Appeal today released its decision, dismissing
the appeal by Milner against her convictions for murder and
earlier attempting to murder Philip Nisbet.
The prosecution case at trial was that Milner poisoned Mr
Nisbet by crushing up Phenergan pills and most likely feeding
them to him in his food.
On one occasion, Mr Nisbet became unwell but recovered. On a
later occasion, the drug overdose was fatal.
There was no dispute that death resulted from the ingestion
of promethazine, the ingredient in Phenergan.
Milner's defence at trial had been that Mr Nisbet committed
Milner's argument on appeal was that the jury's verdict was
unreasonable because the prosecution did not prove beyond
reasonable doubt how it was possible for her to have
administered the drug to her husband without his knowledge.
There was evidence that the crushed pills had a bitter taste,
and that the amount of the drug required to poison Mr Nisbet
may have meant he would have noticed the taste in his food.
Milner argued this meant the reasonable possibility of
suicide was left open.
However, the judgement today said it was open to the jury to
exclude the possibility of suicide on the evidence.
It was not necessary for the prosecution to prove exactly how
Milner had administered the drug so that Mr Nisbet did not
know about it, it said.
The mechanics of administering the drug was simply one factor
for the jury to weigh up in the context of a strong
There was also other circumstantial evidence that supported
the jury's verdict, the ruling said.
Purchases of pills containing promethazine were able to be
linked to Milner and a witness had seen her crushing pills.
She had also expressed a wish to kill Mr Nisbet and take
advantage of his life insurance policy. Suicide notes given
to the police by Milner contained errors and other features
that matched samples of her writing.
The Court of Appeal also rejected an argument that Mr
Nisbet's ill-health on the occasion of the attempted murder
may have been caused by something other than ingesting
There was sufficient medical and other circumstantial
evidence on which the jury could have been satisfied that
promethazine was ingested, the ruling said.
Last December a High Court jury found Milner guilty of
murdering Mr Nisbet in 2009, and guilty of a second charge of
attempting to kill him a fortnight earlier.
She made his death on May 4, 2009 look like suicide in the
hope of cashing in a $250,000 life insurance policy.
And the mother-of-two nearly got away with it when police
referred the Christchurch delivery driver's death as a
suicide to a coroner.
But the Coroner Sue Johnson raised suspicions which prompted
police to launch a homicide investigation.
In February, Justice David Gendall sentenced Milner to the
statutory life imprisonment and imposed a minimum non-parole
period of 17 years.
