For years, baby killer Lise Turner hid in plain sight — shielded by medical uncertainty, misplaced trust and the tragedy of so-called cot death. Her crimes were only uncovered after the death of 8-month-old Michael Tinnion in Christchurch in 1984 exposed a deadly pattern authorities had missed.

Turner was later convicted of murdering three babies — including her two infant daughters, Megan and Cheney — and attempting to murder three other infants.

In the latest episode of Herald true crime podcast A Moment In Crime, senior journalist Anna Leask looks back at Turner’s offending - and those most impacted.

More than four decades later after his murder Michael’s mother Lauree Ashworth, is speaking publicly about the day her son died, the woman she trusted, and the lifelong impact of a crime that shattered her family.

“I live with it every single day,” she said.

In this powerful episode of A Moment In Crime, Lauree shares her memories of Michael, the investigation that exposed one of New Zealand’s worst serial child killers, and how her family has kept Michael’s memory alive for more than 40 years.

In 2025, a man with a lengthy history of stalking and attacking women was jailed for life with a minimum non-parole period of 17 years for murdering his ex-partner, Chantal McDonald, in front of her children at their Christchurch home.

But violent serial offender Nathan Boulter refused to stand in court in front of his victim’s family – including her teenage daughter who spoke for the first time about witnessing the murder – appearing by audio-visual link from another room in the court precinct instead.

The Herald has been reporting on Boulter’s horrifying offending since 2011 – after his high-profile stalking, kidnapping and assault of his ex-girlfriend on Great Barrier Island.

Since then, he has been jailed repeatedly for violent offending against women.

In this episode of A Moment Of Crime senior journalist Anna Leask unravels Boulter's life of offending.

This is the second part of a two-part A Moment In Crime special.

Christchurch woman Nicola Flint told friends she was dying, even showing them the spot where her ashes would be scattered.

They grieved and gave thousands to help her fight cancer.

But police say there is no evidence of any cancer diagnosis – and behind Flint's narrative, a web of forged medical letters, bank payouts and theft from a rugby club – fraud totalling more than $180,000.

Now, as Flint hides out in Wales from the fallout of her elaborate tales, Herald senior crime and justice journalist Anna Leask looks inside the alleged fraud and speaks to those hurt the most by her long-running cancer stories.

In 2016, 77-year-old pensioner Brian Hilton was found on the floor of his Ōpōtiki home — brutally beaten, barely conscious, and covered in blood. He died five days later. Police launched a major homicide investigation, first zeroing in on one local man before turning their attention to another: Harry Matchitt.

A beer bottle found in Hilton’s lounge carried Matchitt’s DNA, and after a series of police interviews, the lifelong Mongrel Mob member made a hazy admission — saying he was “pissed” and may have “pushed and kicked” the elderly man. In 2021, a jury found him guilty of manslaughter.

But two years later, the Court of Appeal ruled his conviction unsafe. The judges found his statements to police likely inadmissible, meaning a miscarriage of justice had occurred. The conviction was quashed — and Matchitt walked free.

In this episode of A Moment in Crime, senior journalists Anna Leask and Jared Savage revisit the violent death of Brian Hilton, the conviction that fell apart, and what became of Matchitt after the case collapsed. Savage also reflects on two decades covering crime and justice, and his work investigating New Zealand’s gang world.

In 1991, Bronwyn Warwick crossed a line that would define her forever. The transgender former sex worker murdered a Ponsonby pensioner during a botched antiques robbery. But the story didn’t end with her arrest. Decades later, Warwick’s life took even darker and more tragic turns: years behind bars, living as a woman in mens prisons, release and relapse, and finally, a debilitating diagnosis.

In this gripping conclusion to A Moment in Crime: Diary of A Killer senior crime and justice journalist Anna Leask unpacks the murder and Warwick's long road of remorse, addiction, and survival. Through exclusive access to her writings and interviews, this episode reveals the woman behind the headlines.

Before she was a convicted killer, Bronwyn Warwick was a child who never stood a chance. Growing up in a family that didn't understand or accept her and facing violence, addiction, and rejection, Warwick’s early years set the stage for a life defined by crime and chaos.

In the first of two episodes about Warwick's life A Moment in Crime: Diary of a Killer senior crime and justice journalist Anna Leask delves into her complex past — from petty offending and time in youth facilities to the moments that shaped her identity as a transgender woman navigating an unforgiving system. Drawing from rare interviews, court records, and Warwick’s own prison diaries, this is the story of a person living on the margins, constantly running from pain and punishment. Before the world knew her name, Warwick was already fighting a losing battle — with herself, the law, and the world around her.

In May 1992 Brian Schlaepfer shot or stabbed six members of his family to death at their South Auckland farm.

The 64-year-old murdered his wife, three sons, daughter in law and grandson.

His nine-year-old granddaughter, Linda, was the sole survivor, having hidden in a wardrobe and providing crucial information to the police during the ordeal.

The massacre began after a domestic argument and ended when Brian took his own life.

The case remains one of New Zealand’s worst family tragedies.

In this episode of A Moment In Crime senior journalist Anna Leask explains the case and reveals the harrowing 111 call between young Linda Schlaepfer and Stuck.
