But by early 2024 his mental health was rapidly declining, he was having troubles with his relationship and he was using cannabis. In May 2024 he was admitted to a mental health facility after an altercation with a relative. About a week later he was released back into the community.
Five days later he killed “the most important thing to him” – his mother Heather Condon. Once again, he would be found not guilty of murder by reason of insanity.
The case was shrouded in secrecy until RNZ revealed it last year.
On Monday, the Supreme Court dismissed Parr’s application for leave to appeal a decision declining name suppression, allowing RNZ to reveal the full details of the killing.
RNZ has obtained court documents, including statements from those who knew him best, that lift the lid on Parr’s life, his mental health battles and his family’s anger with the mental health system.
“How can someone who has previously killed another person be able to remain free when the warning signs are right there for all to see?” his father wrote.

‘Cold and sinister’
Leslie Raymond Parr was born in 1974. He was the youngest of four siblings, and a year after he was born the family moved to Whanganui.
Parr’s father Harold Parr would later tell police the children were “all good kids”.
“My boys and I would do lots of things together, like hunting, fishing; and I coached their school rugby team.”
Wanting the best for his sons, Harold Parr sent them to St Stephen’s secondary school in Auckland.
After finishing school, Leslie Parr returned home. His parents separated and Harold Parr moved to Taupō before going to live in Wellington.
Leslie’s troubles were first expressed in 1995 when he developed insomnia, with a decrease in appetite over several months.
He was admitted to a psychiatric unit under the Mental Health Act in August that year after attempting suicide. On admission, he was overheard saying “Satan will kill us all. Here to save you.”
A psychiatrist found he was suffering from a disorder of the mind.
“I can only say, most emphatically, that Mr Parr should remain in a psychiatric hospital as an involuntary patient. He is really very ill and is at risk of suiciding. I fear the type of schizophrenia he has is one that is associated with impulsive and often successful suicide attempts, usually based on concealed delusional thinking.”
Parr was then made the subject of a compulsory treatment order. After responding well to medication he was released.
Harold told police about “episodes” Leslie had while living with him.
“I knew he was suffering from something serious because he was so dark and cold when he had an episode.
“I noticed it mostly in his eyes, they were just cold and sinister looking.”

‘I had to kill her’
Leslie met Fiona Maulolo in 1996 and the pair moved to the Hutt Valley.
Soon after meeting Maulolo, Leslie stopped taking his antipsychotic medication regularly and had an “episode”, which led to him being admitted to Porirua Hospital.
He was described as “depressed and delusional”, thinking that his father was Satan. He was predicting the end of the world in the year 2000, and said he heard voices telling him to kill himself.
When his medication was reintroduced he began to deny psychotic symptoms.
On the day he was due to be discharged from hospital he seriously assaulted a police officer who was visiting the ward.
Parr told a psychiatrist he did not believe he was to blame “because the constable had looked at him”.
Parr was then made a compulsory inpatient for six months under the Mental Health Act.
However, he was released nine days later, on March 28, 1996. He was not seen again by mental health services until April 15, 1997 after he was found semi-conscious in a carport at Maulolo’s property.
He was transported to Hutt Hospital by ambulance and admitted to the Intensive Care Unit. He later regained consciousness and after a psychiatric assessment was discharged into his father’s care.
Three days after he was admitted to hospital his father and another person went to collect some clothes for him from Maulolo’s home. On arrival, they found Maulolo’s daughters and a relative who had not heard from Maulolo for a week.
They forced their way into the home and found Maulolo’s body in the bath.
Maulolo had been decapitated with her head found in a plastic bag in a clothes dryer. Forensic evidence revealed Parr had driven a chisel multiple times into her heart before decapitating her.
He went on trial for murder in 1998. At trial, police said Parr and Maulolo’s relationship was “volatile” with neighbours describing constant verbal arguments and fights between them. There was a suggestion Maulolo was looking to end the relationship.
He told police he killed her because he believed she was Satan.
A jury found Parr not guilty by reason of insanity. A judge ordered he be detained in a special secure unit and not freed without the health minister’s authority.
A coroner later said Parr’s treatment had been seriously deficient.
There had been no ongoing assessment of Parr’s mental health state, or monitoring of his medication needs between when he was discharged and the murder.
Parr’s hospital file showed that his responsible clinician, Linda Astor, had done a clinical review of his mental health.
She claimed she had examined Parr and “consulted with other health professionals” involved in his treatment and care, and that she had taken their views into account when assessing the results of her review of his condition.
She said he was fit to be released from compulsory status, nine days into what was supposed to be six months as a compulsory patient.
There was, however, no evidence Astor saw Parr or consulted with other health professionals involved in his treatment and care.
Astor later fled the country and was unmasked as a bogus psychiatrist.

‘He was very loving and caring’
Parr was transferred to Te Āwhina, an inpatient acute mental health service, to be closer to his family in 2000. He was put on a different medication and his mental health “improved a lot”, his father said.
In the coming years, he started doing day visits accompanied by a nurse and even got a job.
Once he was eventually released from Te Āwhina he started going by the name Zac.
At first, he lived with his mother, before finding his own place. Harold said Leslie looked after his mother and grandfather, including doing their lawns.
In 2021, the special patient order was removed.
In 2023 Leslie met Rachel (not her real name) via online dating. By September they were in a relationship.
The woman told RNZ Leslie, who told her his name was Zac, seemed “perfectly fine”.
“He was very loving and caring and treated me incredibly well.”
She would later tell police Leslie was “always helping his family … especially his mum and as far as I knew he was a good person, a kind person”.
Harold told police that Leslie spent several years working at a freezing works but left after people found out about Maulolo’s death. He went on the benefit for a few years before getting a job at a milk factory cleaning trucks.
In March 2024, the work “dried up”, his father said, and Leslie was laid off and went back on the benefit.
Harold said he visited his son days before his birthday in April to help as he was having a party.
“When I arrived, Leslie was there with a friend, and they were bouncing off the walls. It was obvious him and his friend had used drugs.”
The following day Harold told Leslie to get off the drugs or he would call the police.
The pair did not have much contact after that as they were “both annoyed at one another”.
It was not until May that Leslie told Rachel he killed his former girlfriend in 1997.
“I laughed and thought he was joking but he had a deadpan face and I eventually realised he was not joking, and I screamed and told him to leave.”
After he left, she looked him up online and read about what happened to Maulolo.
“At the time I thought it had been years earlier and he wasn’t well at the time and the case had not been handled well, lots of mistakes involved.
“So, I believed it was a one-off thing because of all the circumstances and not likely to happen again.”
Leslie also sat down with her and said he was on the wrong medication at the time and claimed he begged them not to let him go because he knew he wasn’t well.
The admission
In May 2024, after an altercation with a relative, he was admitted to a mental health facility.
Rachel said after the admission she became “very scared and very terrified”.
He was released after about a week, on May 30. Following his release, he became preoccupied with the loss of keys to his ute, which he could not find.
Harold told police his son did not sleep for four nights, worried about his ute.
“He was so agitated about his keys and seemed really scared and stressed,” he said.
“I could tell how much it was affecting him and he just wouldn’t let it go.”
Leslie visited his father’s home on June 3. He did not go inside, and just sat on the back doorstep.
“He started to remind me of how he behaved in Wellington when the other incident happened.
“Leslie had those dark eyes and wasn’t present. The biggest thing I notice when he’s like that is you can’t reason with him. He talks so fast and frantic that you don’t even have time to answer.”
Rachel’s concerns were also growing.
“I started to see a side to him I didn’t like.”
He started becoming delusional and irrational, which appeared to coincide with his consumption of marijuana increasing.
“He said some weird things to me about his mum not being a human and that she was a demi-god.”
When she heard he was going to be released from the mental health facility she worried “maybe he’s gonna come for me”.
“But I didn’t want to come tell the police because I thought I needed to try get out of it quietly, because I thought if I piss him off … you know you can get protection orders … but it’s just a piece of paper. They can still kill you.”
A day after he was released Leslie messaged Rachel and said he did not love her anymore and wanted to break up.
The following morning, about 4.30am, Rachel woke up to tapping on her ranch slider. He was standing outside. He said he had been drinking with his friend all day and night and he had been sick and then drove to her place. He ended up staying the night.
Two days later she was mowing her front lawn when she saw him sitting in his car on the road watching her. Rachel asked him what he was doing, and he replied: “Oh, I love you and I want to be with you”.
She told him he was stalking her and was being “creepy”. He took off, but she then saw him again about an hour later across the road. She told him to go away, and she would see him later.
The next night he visited her home after repeatedly asking to come over. The couple argued in her bedroom.
Rachel said she told him she did not think the relationship was working and he needed to leave.
He refused to leave and asked her what she was going to do about it. She threatened to call the police and he left.
A second killing
The following morning, the day of the second killing, Parr called Rachel to say he needed someone to pick him up as he had driven out of town and his car broke down in Bulls. Rachel said she was reluctant to help him but eventually relented.
However, when she got there he was not there. Rachel then called Heather and said she could not find him.
Heather said she wondered if he was testing her.
“I said to her, ‘Yeah, he’s been acting very, very strange’ and she started to get upset and said, ‘Yes, I’m very worried about him and he’s been saying that he can’t trust anybody, that he can’t trust me, he can’t trust his dad and he only trusts you and that he only feels safe with you’.”
Shortly after, Leslie called Rachel and said his phone had gone flat and he got a lift with someone else.
Leslie had also been calling his father earlier in the day. Leslie’s sister called Harold shortly before 1pm saying she was concerned about her brother and wanted him to stay with her to relax about his ute.
“I told her it was better for him to be in Whanganui near the psych unit and where there are more cops in case something happened.”
Harold then drove to Leslie’s home. He was not there, but just as Harold was leaving Heather arrived.
The pair talked about how their son was behaving, including his worries about his keys and his drug use.
About 20 minutes later, Harold got a call from Heather to say Leslie was at her home when she got there.
“Heather said they had an argument because he was angry at her for calling [Rachel] and getting her involved.
“She said Leslie told her he needed the car, so she threw him the keys and he took off.”
Harold tried calling Leslie to see where he was but he did not answer.
About 1.45pm Leslie called Harold and they talked about hiring a trailer to pick up his ute.
Harold then picked Leslie up from Heather’s home and headed to the hire centre.
“When we got there Leslie changed his mind about picking up his car.
“We had a heated discussion about picking up his car and mucking around, but he still didn’t want to go get it, so I dropped him back at his mother’s.”
Harold then went to the supermarket. While there he called Leslie’s sister, who said Leslie had been talking about everyone being out to get him.
“[She] said she could hear in his voice that he didn’t seem well but insisted she could help.
“I told [her] we should call police and try get him back to the hospital.”
He then called Leslie’s nurse to get his doctor’s number.
He claimed the nurse told him Leslie went to get this “shot” around 1pm and was “very cagey”.
“I asked [the nurse] if she drug tested Leslie, but she didn’t because she thought he might think she was picking on him and make him angry.”
The nurse said she would call Leslie’s doctor and tell him how he was behaving and express the family’s concerns.
At 4.53pm Harold received a call from Leslie asking for help. He said he was at his mother’s home and the mob was after him.
“He was puffing and was out of breath like he had been fighting or running.”
At 5.35pm Leslie phoned again and said the same thing about needing help, but he was now at his home.
Court documents reveal that between 4.50pm and 5.39pm Leslie fatally stabbed his mother with a knife. He then went to an associate’s home, arriving about 6.20pm.
He walked into the address and sat on the doorstep asking his associate “cuz do you know where to get a gun?”
Leslie said he needed the gun because the Mongrel Mob was after him.
He then called his sister and a plan was made to go to Raetihi.
Leslie got into his associate’s car and while they were travelling he said “Cuz, I’ve killed Mum”.
Asked why, Leslie said “Mum’s possessed, Mum’s possessed. I had to do it.”
The associate got out of the car and walked away. Leslie then drove off. The associate eventually drove to the Whanganui Police Station and told them what Leslie had said.
Later that evening, Leslie arrived at Rachel’s home. He made himself a chicken sandwich and about 7pm they went to bed.
Meanwhile, Leslie’s family were becoming concerned as they were unable to get hold of him or Heather.
They thought she may have gone to mass, but it was “out of character” for her not to have her phone. Harold drove to her home but there were no cars outside.
He checked the laundry and shops, but could not find her.
At 8.25pm police found Heather dead in the garden beside the porch.
Harold told police that as soon as he was told about Heather’s death he became concerned for Rachel and her daughter.
“I didn’t know any details of what happened to Heather, but I immediately thought Leslie was the only one capable of doing that and given how he had been behaving it was likely.”
About 1am Rachel woke to get some water and saw lights outside.
“I woke him up and said ‘there’s all these lights and things’ and he just got up and shot out, and then suddenly there’s armed offenders squad and dogs and guns being pointed and stuff like that.”
Rachel asked the police what was going on.
Leslie was told he was under arrest for murder and he replied: “Yes, I know”.
The following day, Rachel was told what had happened.
“I was in disbelief, I was sickened and distraught.”
Heather was “the most important thing to him”, she said.
“This is where it is so hard to believe what he’s done to her because he would talk to her every day, if not multiple times a day.
Harold told police Leslie “loved his mother” and would do anything for her.
“When he’s well he’s such a caring person.
“Leslie wasn’t well though and he is capable of anything when his mental state is unstable.”
Mental health system ‘failed everybody’
In April last year in the High Court at Whanganui, Justice Karen Grau said there was no question Parr was responsible for his mother’s death, but that he was “legally insane” at the time he caused her death.
“I am satisfied, based on the reports of the experts, that it is clear Mr Parr suffered from a disease of the mind, a relapse in his longstanding schizophrenia, at the time he killed his mother.
“It is not the case that he did not understand the nature of his actions, but as the experts have concluded, and with which I agree, he was incapable of understanding his acts were morally wrong, and they were driven by his delusional beliefs.”
He was ordered to be detained as a special patient under the Mental Health Act.
Justice Grau said the case happened “against a backdrop of apparent significant failures in the mental health system”.
Harold Parr wrote to Justice Grau as part of proceedings, requesting name suppression for his son and Heather.
He said he had attended “countless appointments” and meetings relating to his son’s mental health over the years.
“I have met his doctors and psychiatrists and have a good understanding of the mental health system, what services are provided and some of its failings.”
He referenced Maulolo’s killing, saying the details of it were “too horrific to repeat”.
He wrote his son’s release by Astor was “unlawful and improper” and said Leslie “should never have been let out”.
“If the proper procedures were followed Fiona would not have been killed in 1997.”
He also referenced the allegations that on the day Leslie killed for a second time he was supposed to be drug tested but wasn’t because he was “acting cagey” and the staffer didn’t want him to feel he was being “picked on”.
“This is a so-called health professional who observed unusual behaviour from a person with severe mental health issues and they didn’t do anything about it. She didn’t test him and basically allowed him to leave. A few hours later Heather was dead.”
Harold wrote the build-up to Heather’s death was “predictable”, adding his son was “on a downward spiral”.
“The health system is not aggressive enough to make decisions. They pussyfoot around because they don’t want to hurt people’s feelings or upset them. But the consequence of them being indecisive is the reason that we find ourselves in this predicament now. Heather is dead and it could and should have been prevented,” he said.
“There are more questions than answers. The health system had Leslie in their custody and released him. A health professional saw Leslie on the day he killed Heather, described him as being cagey, did not do the blood test and let him go without anything. How? Who is accountable? How can someone who has previously killed another person be able to remain free when the warning signs are right there for all to see?”
Rachel earlier told RNZ Leslie should not have been released from the mental health facility five days before the killing.
“I don’t know how they couldn’t have noticed how he was unwell unless he put on a really good show.”
She believed there had been a “massive failure” in the mental health system.
“It failed him, it failed everybody twice.”
Rachel often wondered whether Leslie may have killed her as well. She was in therapy and said she was “a mess”.
“I feel sad. I feel sad for the victims, I feel sad for him. I feel it’s just sad all around really. He was unwell, and he just wasn’t given the care that he should have been given.”
Reviews underway
Health New Zealand (HNZ) national director of mental health and addictions enhancement, Phil Grady, said on Monday the case was incredibly tragic.
“Our thoughts remain with the family, friends and communities affected. On behalf of Health New Zealand, I extend our heartfelt sympathies to everyone impacted,” Grady said.
“It is completely understandable that people feel let down and are seeking answers. We acknowledge those concerns and want to approach them with openness and respect, while recognising the deep impact this has had on both victims’ loved ones, the wider community, and the staff involved in Mr Parr’s care.”
Grady said HNZ also recognised that questions had been raised about aspects of Parr’s care and the decisions made at the time.
“These were complex clinical decisions based on the information available, and the external review has carefully examined those concerns.
“Where the review has identified areas that could be clearer or stronger, such as expectations around drug screening, information sharing and clinical oversight, we are acting on those findings to improve consistency and strengthen practice across the service.”
Health NZ reviewed every serious adverse event that occurs within its services, and was committed to learning from them, he said.
“An external review of the care Mr Parr received leading up to this event is currently being finalised, led by senior Health NZ staff from outside the Central Region to ensure independence.
“We are committed to implementing any recommended changes so that we continue to strengthen the quality and safety of the care we provide.
“Events of this nature are incredibly tragic, but when they occur, we take them extremely seriously. The learning from this event is already informing improvements across the service, including strengthening clinical leadership, improving information sharing, clarifying clinical protocols such as drug screening and enhancing whānau engagement and staff training.”
Mental health care in the community was complex, and risk could never be removed entirely, he said, “especially in the case of serious mental illness, but these improvements are designed to strengthen safeguards and provide reassurance to the people we care for, their whānau, and the wider community”.
The Ministry of Health also extended its deepest sympathies to the families, friends and communities affected.
After Parr’s second killing, Health New Zealand commissioned an external review into his care.
“Health New Zealand has already made changes since the incident, and I support their work,” director of mental health Dr John Crawshaw said.
He said the review was being led by an external expert panel and is near completion.
“Once the external review is available, I will carefully consider whether any further actions are required.”
Mental Health Minister Matt Doocey said his thoughts were with the families affected.
“I have made it very clear to HNZ that patient and public safety must always be paramount, clearly situations like this are not good enough. New Zealanders deserve to have trust that when people are in the care of mental health services, the appropriate care is being taken to ensure patient and public safety is at the forefront of all decisions,” he said.
“As minister, my focus is on ensuring agencies put in place all necessary changes to prevent tragedies like this from occurring again. I have made it very clear to Health New Zealand that they must move quickly to implement the findings of the reviews and make all necessary changes to prevent this from happening again.”
Doocey was awaiting the director of mental health’s decision on whether he was satisfied with the review and whether any further action needed to be taken.
Chief victims adviser Ruth Money said the case was “heartbreaking and preventable”.
When RNZ first revealed the case she called for a Royal Commission of Inquiry into forensic mental health facilities.
On Monday she said she stood by those calls, “given that, unbelievably, this is not the only recent case where someone in forensic mental health ‘care’ has gone on to kill twice”.
“An inquiry that has mandated recommendations is the only way the system will improve, as opposed to Health NZ continuing to mark their own homework every time a tragedy such as this occurs. These victims and the community deserve infinitely better.”
