In a dramatic breakthrough that has stunned a grieving family and reignited painful memories across Western Sydney, police have charged the ex-boyfriend of a young pregnant mother with her murder — nearly nine years after she was found dead inside her Kingswood home.

Max Spencer, now 30, was arrested at a property north of Coffs Harbour just before 7.30am on Tuesday and charged with the murder of Hayley McClenahan-Ernst, who was 21 and pregnant at the time of her death in May 2017.

The arrest marks the end of a long and frustrating wait for justice for Hayley’s loved ones, who have spent almost a decade pleading for answers while living with the agony of never knowing exactly what happened to the vibrant young woman and her unborn child.

Hayley was discovered unresponsive at her Derby Street home in Kingswood, in Sydney’s outer west, after paramedics were called. Despite desperate attempts to revive her, she died at the scene. Her death was immediately treated as suspicious, yet for years the investigation appeared to stall, leaving her family in limbo.

Now, with Spencer in custody and due to appear in court, the case has taken a decisive turn — but for Hayley’s mother and sister, the news has reopened deep wounds while offering a sliver of long-awaited hope.

“We Have Never Stopped Missing Her Smile”: Mother’s Heartbreaking Reaction

Hayley’s mother, Lisa Ernst, who has rarely spoken publicly over the years, broke her silence in the hours after the arrest, describing the overwhelming mix of emotions she is now feeling.

In an emotional statement released through police and obtained by Daily Mail, Ms Ernst said her daughter was “deeply loved” by everyone who knew her.

“We have never stopped missing her smile, her infectious laugh, and the fierce love she had for her children,” she said. “My grief over losing my daughter has only deepened with time, especially as I still have no answers about what happened to her.”

Ms Ernst revealed that the family had never given up hope that one day someone would be held accountable.

“Hayley was so excited about becoming a mum again. She had her whole life ahead of her. This arrest doesn’t bring her back, but it might finally give us some of the answers we’ve been desperate for.”

Friends say Lisa has carried the weight of the loss quietly but fiercely, often visiting the site of her daughter’s home and keeping Hayley’s memory alive for her surviving grandchildren.

One close family friend told Daily Mail: “Lisa has been a rock for the kids, but inside she’s been broken. Every milestone — every birthday, every Christmas — she wonders what Hayley would have been like as a mum. Today’s news has brought tears, but also a tiny bit of relief that the system might finally be working.”

Sister’s Raw Emotion: “We Just Wanted the Truth”

Hayley’s sister has also spoken out in the wake of the arrest, expressing a complex wave of relief mixed with renewed pain.

In a brief but powerful interview, she described her older sister as “the glue of our family” — a fun-loving, caring young woman who was full of life and dreams for the future.

“She was pregnant and so happy. She talked about the baby all the time. To think someone took that away from her… it still doesn’t feel real after all these years,” the sister said, fighting back tears.

She revealed that the family had grown increasingly frustrated with the slow pace of the original investigation, describing years of unanswered questions and what felt like a lack of urgency.

“We just wanted the truth. We wanted to know what happened to Hayley and why. Now that someone has been charged, it feels like a weight has been lifted — but at the same time, it brings everything rushing back.”

The sister spoke of the lasting impact on the family, particularly Hayley’s young children who lost their mother at such a tender age.

“They don’t remember her the way we do, but we make sure they know how much she loved them. This arrest is for them too — so they can grow up knowing someone was held accountable for what happened to their mum.”

The Day Everything Changed: What Happened in Kingswood

On that fateful day in May 2017, paramedics were called to the modest home on Derby Street in Kingswood after concerns were raised about Hayley’s welfare.

When they arrived, they found the 21-year-old unresponsive. Despite their best efforts, she could not be revived. Police quickly deemed the circumstances suspicious and launched an investigation under Strike Force Fielding.

At the time, a 21-year-old man known to Hayley — understood to be her ex-boyfriend — was spoken to by police, but no charges were laid and the case gradually went cold.

Over the years, police made periodic public appeals for information, but leads appeared to dry up. Hayley’s family continued to push quietly for the case to be revisited, hoping advances in forensic technology or new witnesses might finally break the deadlock.

In March 2026, NSW Police announced a renewed push to solve the suspicious death, describing it as a “suspected murder” and appealing again for anyone with information to come forward.

That renewed focus appears to have paid off. Detectives say “fresh information and advances in investigative techniques” — possibly including re-examination of forensic evidence or new witness statements — led to Spencer’s arrest this week.

A police spokesperson confirmed the man was arrested at a property north of Coffs Harbour on the New South Wales mid-north coast and charged with murder. He was expected to appear in court later on Tuesday.

Officers have declined to release further details about the alleged circumstances of Hayley’s death, citing the active court process, but sources suggest the investigation explored possible domestic-related motives.

Who Was Hayley McClenahan-Ernst?

Those who knew Hayley remember her as a bright, loving young woman full of potential.

At just 21, she was already a mother and excitedly preparing to welcome another child. Friends described her as someone with an infectious laugh, a warm personality and a deep love for her family.

She had dreams of building a stable life for her children and was known for her kindness and quiet strength.

Her death not only robbed her children of their mother but left a permanent scar on her extended family, who have spent nearly a decade navigating grief without closure.

One former neighbour in Kingswood recalled Hayley as “a lovely quiet girl” who kept mostly to herself but always had time for a friendly chat.

“It’s heartbreaking to think she was taken so young, especially while pregnant. No family should have to go through what they’ve been through.”

The Long Road to Justice: Why It Took Nine Years

The case highlights the challenges of investigating suspicious deaths, particularly when initial evidence is limited or witnesses are reluctant to come forward.

Strike Force Fielding conducted extensive inquiries in the months after Hayley’s death, but without sufficient evidence to lay charges, the file was eventually moved to the unsolved homicide unit.

Cold case reviews in recent years, combined with improvements in DNA technology and digital forensics, have led to several breakthroughs in long-dormant NSW cases.

Police have not detailed exactly what prompted this latest breakthrough, but the timing — coming shortly after a public appeal in March — suggests renewed media and community attention may have encouraged someone with crucial information to speak up.

For Hayley’s family, the nine-year wait has been agonising. They have described feeling forgotten at times, with the case slipping from public view as newer crimes dominated headlines.

Today’s arrest has brought a renewed sense of validation that their persistence mattered.

Reactions Pour In as Community Processes the News

The arrest has triggered an outpouring of support for Hayley’s family across Western Sydney and beyond.

Local politicians and domestic violence advocates have used the moment to call for better resourcing of cold case units and faster responses to suspicious deaths involving young women.

One community leader in the Penrith area said: “This case shows that justice can still come, even after many years. But it also shows how long families have to suffer while waiting.”

On social media, tributes to Hayley have flooded in, with many sharing photos of the smiling young mum and calling for stronger protections for pregnant women in volatile relationships.

Hayley’s sister spoke of the mixed emotions the family is experiencing: relief that someone has been charged, but also fresh grief as the details of the case are once again thrust into the spotlight.

“We’re grateful the police didn’t give up, but this brings everything back. We just want the truth to come out in court so we can finally start to heal.”

What Happens Next?

Max Spencer has been charged with murder and is expected to face court in the coming days. Police have urged anyone with additional information to contact Crime Stoppers, emphasising that the investigation remains active.

For Hayley’s mother Lisa and her sister, the coming months will likely be emotionally gruelling as they prepare to relive the events of 2017 through the court process.

Yet they remain determined to see justice served — not just for Hayley, but for her unborn child and the family left behind.

In a final poignant reflection, Lisa Ernst earlier this year spoke of the enduring pain: “My grief has only deepened with time.”

Today, with an arrest finally made, that grief may one day be accompanied by answers.

Hayley McClenahan-Ernst was a young mother with dreams, laughter and love to give. Nine years after her life was cut short in suspicious circumstances, her family stands one step closer to the truth they have fought so hard for.

The road to full closure remains long, but for the first time in nearly a decade, there is movement — and a name now facing the weight of justice.
