The grieving sister of Adrian Humphreys who was stabbed to death in his tent at a remote campground has described the teen who murdered him as a monster.
“Adrian helped people enjoy their lives, he did not deserve to have his ended in this cruel and unjust way,” Taresa Keatley said in her victim impact, read on her behalf at the sentencing of Justice Williamson-Atkinson on Wednesday.
“Only a monster could have done that. My grieving and feeling of loss will never go away, knowing he died alone, scared and in great pain.”
Williamson-Atkinson, 17, appeared in the High Court at New Plymouth where he was jailed for life with a minimum period of imprisonment (MPI) of 11 years on charges of murder and burglary.
Flanked by Corrections officers, he wore a grey tracksuit as he stood in the dock where only glass separated him from his mother, grandmother and girlfriend, who were seated behind him in the public gallery.
Williamson-Atkinson was asked if he had anything to say as to why a sentence should not be passed upon him according to the law.
“I didn’t do this,” he told the court.
But at a trial in November, he was found guilty of murdering Humphreys, whose body was found at Bushlands Campground in Tāngarākau, eastern Taranaki, on May 7, 2022.
Williamson-Atkinson was on a programme for at-risk youth when he snuck into Humphreys’ camper to steal his car keys and then stabbed him five times.
At sentencing, Humphreys’ sister Taresa Keatley spoke, through her victim impact statement, of the pain and disbelief she and her parents were grappling with following his death.
“All we have now are his ashes and our memories of a wonderful, caring, considerate, and funny brother and son.”
The siblings were close as children and Keatley said that bond remained despite the two living in different countries in their adult years.
She said Humphreys, a former Royal Air Force serviceman from the United Kingdom, returned home in 2019 to visit his family.
“The four of us - mum, dad, Adrian and myself - booked a hotel for a few days. The family was back together.”
They went fishing, played cards and dominoes, and spent hours talking over coffee.
“Little did I know that this would be the last time I would see Adrian.”
Humphreys’ parents, Rose and George Humphreys, also provided a victim impact statement in which they said no parents should ever outlive their children.
Tears now flow for the couple almost daily, with their grief bringing them to their knees both mentally and physically, they said.
“It hurts deep down that we could not be there for his funeral, knowing we could not say our goodbyes properly.”
Following his funeral in New Zealand, Keatley returned to the UK with his ashes and the family held a memorial service for him at the church at which he was christened.
His parents said it was full of people from his school days, colleagues, and people from New Zealand.
“That was the impact he left on people; happy, caring, ready to help. We loved him so much.”
At sentencing, defence lawyer Matthew Phelps argued a life term of imprisonment would be manifestly unjust, but Crown prosecutor Cherie Clarke submitted the case did not reach the threshold to avoid such a sentence.
Phelps said Williamson-Atkinson was 15 at the time of the murder and had been diagnosed with fetal alcohol spectrum disorder (FASD) and attention deficit hyperactivity disorder (ADHD).
He pointed out adolescents were neurologically different from adults by having less self-control, being more impulsive, less able to consider the impact of their behaviour, more likely to engage in risky behavior and being more vulnerable to peer pressure.
“And that is exactly what we are dealing with in this case. The offending and the behaviour, in my submission, is consistent with all of those factors.”
Phelps submitted the court then had to factor in Williamson-Atkinson’s cognitive impairments, which he said further impacted his executive functioning.
“It means he has extreme difficulties with impulsivity, he tends to act in the moment, he has a reduced ability to understand and think about possible consequences.”
Referring to a report provided to the court, Phelps said that while Williamson-Atkinson had a knife and wanted to steal a car, he lacked the ability to form a detailed plan of action.
“It’s for that reason that we say, the suggestion that Mr Williamson-Atkinson must have had murderous intent sits uncomfortably with some of the material that the court has.”
Phelps submitted the teen’s personal background, including the unstable management of his ADHD and FASD, also needed to be factored into public safety considerations.
“He has never had the chance to manage his behaviour.”
Phelps argued that given Williamson-Atkinson’s youth, cognitive issues, background factors, and the help he will receive behind bars, a finite sentence with an MPI of 50 per cent was appropriate.
But Clarke submitted that when there was a heightened risk of public safety, which she said applied in the teen’s case, then a sentence of life imprisonment was rarely found to be manifestly unjust.
Clarke said Williamson-Atkinson had shown no remorse or insight into his offending.
“And that may be and is probably impacted by FASD but FASD can’t exclude that and it therefore impacts on his ability to rehabilitate.”
“It heightens the risk to the public ... and therefore it just cements that the presumption of life imprisonment has to apply in this case.”
Clarke submitted it also cemented that an MPI of at least 10 years should be imposed.
Justice Francis Cooke found the teen’s was not an exceptional case where it was manifestly unjust to impose life imprisonment.
But he did find it was appropriate to impose a lower MPI than the usual 17 years.
In sentencing him to life with an MPI of 11 years, Justice Cooke encouraged the teen to make the most of his time in jail.
“Eleven years may sound like a long time before you are considered for parole but it is important that you think about your future and you take advantage of all of the help you have in prison, and do things like completing NCEA qualifications.
“It is only by getting help and working on yourself that you can maximise the chances of you being released once the minimum period of imprisonment passes.”
A one-year term of imprisonment on the burglary charge will be served concurrently.
Following the sentencing, detective senior sergeant Drew Bennett, who led the investigation, acknowledged the outcome.
“Adrian’s family, friends and work colleagues were important to him, and we know his loss will continue to be keenly felt,” he said in a statement.
“While no outcome will bring Adrian back to his family, we hope that the sentence today allows them to close this chapter of the process.”
He acknowledged Keatley’s “grace and dignity” throughout the past 22 months, the support of the Tāngarākau community, and the work of the investigators and trial team.
Williamson-Atkinson was staying at Bushlands Campground with Start Taranaki, a programme for troubled youths run in partnership with Oranga Tamariki, at the time of the murder.
The Hastings teen had taken a knife from the communal kitchen at the campground and snuck out of his tent during the night.
He wanted to leave the campground but needed a car so he broke into Humphreys’ camper to steal his keys and, during the burglary, repeatedly stabbed him.
Humphreys had arrived at Bushlands, located along the Forgotten World Highway, on May 6, 2022.
At the time of his death, the outdoor enthusiast lived in Rotorua where he worked at Southern Cross Healthcare as an anaesthetic technician.
He had stayed at Bushlands Campground only weeks before and was excited to be returning with the camper trailer he had just bought.
Within hours of his arrival, three Start Taranaki youth workers arrived at the camp with Williamson-Atkinson and two other teens.
The Kaponga-based organisation provides an eight-week programme to at-risk youth involving time spent in the bush, the beach, a marae, and in a residential space learning skills such as barbering.
Evidence was heard at trial that the youth workers generally slept in the same tents as the teens and removed knives from kitchens at any site the programme visited. But that did not happen on this trip.
Early the following morning, two of the youth workers discovered Humphreys’ body. He was lying face down on the ground, about 20 metres from his camper.
Williamson-Atkinson’s DNA was found around the cut holes in the sleeping bag Humphreys was in when he was stabbed, and Humphreys’ blood was found on the sleeve of the teen’s jersey.
Evidence was also heard that during a conversation with a relative, Williamson-Atkinson confessed to having “killed someone”.
But at trial, defence lawyer Nicola Graham maintained it was another teen on the programme who had killed Humphreys.
Williamson-Atkinson had told police he had gone into the camper after the other teen stabbed Humphreys and took the knife away for him. He said the other teen had planned to steal Humphreys’ car keys.
There was no forensic evidence that linked the other teen, who has refused to provide police with a DNA sample and a statement, to the stabbing.
He has permanent name suppression and has not been charged in relation to Humphreys’ death.
