Who Is Hakyung Lee? The Troubled History Behind New Zealand’s ‘Suitcase Murders’

The sentencing of Hakyung Lee — the New Zealand mother convicted of killing her two children and hiding their bodies in suitcases for four years — has dominated headlines. The facts of the case are now widely reported: a life sentence, a minimum non-parole period of 17 years, and a crime that stunned both New Zealand and South Korea.

But beyond the courtroom updates, a larger and more difficult question lingers beneath the surface: who was Lee before this crime, and what deeper pressures, failures, and systems shaped the path that led to one of New Zealand’s most disturbing child-homicide cases?

This article looks past the verdict to interrogate the historical, social, and psychological context that the breaking-news cycle didn’t have time to unpack.


Why This Is the Big Unanswered Question

Even in high-profile murder cases, the public tends to receive only two versions of the accused: the person they were at the moment of the crime, and the person the prosecution presents in court. Everything in between — the roots of stress, isolation, migration, trauma, and the way these forces compound over time — is often left unexplored.

Lee’s case demands a deeper analysis precisely because the facts are so extreme: two young children killed in their own home, their bodies hidden, the mother fleeing the country, and the remains discovered years later only because a storage unit was auctioned off. Crimes of this nature don’t emerge from nowhere, and the public instinctively wants to understand what happens before someone commits the unthinkable.

The “why” behind Lee’s actions is not a justification — it’s the missing half of the story.


What the Breaking News Didn’t Explain

The news cycle has focused on the crime, the sentencing, and the dramatic discovery of the suitcases. But several unanswered elements remain:

  • Lee’s psychological decline following her husband’s death in 2017 was mentioned only briefly, without deeper context.

  • The family’s social isolation — living far from extended relatives, without a strong support network — was treated as background rather than a structural factor.

  • Her financial instability after becoming a single parent was referenced, but not explored.

  • Authorities had no record of formal mental-health intervention, despite Lee’s mother telling prosecutors her daughter expressed suicidal thoughts.

  • The years between the murders and her arrest — how she lived, how she concealed her identity, how she justified this to herself — remain largely unaddressed in public reporting.

These gaps don’t excuse the crime; they simply reveal how much remains unknown about the years before and after the killings.


The Deeper Context: Legal, Psychological, and Social Pressures

1. The Legal Landscape in New Zealand

New Zealand courts have historically viewed child-homicide cases through two concurrent lenses:

  • criminal responsibility, and

  • mental-health deterioration, especially following trauma or overwhelming caregiving stress.

Cases such as the 2006 Auckland child-homicide (R v L) and later sentencing remarks in R v K emphasize the importance of determining whether a parent acted during a period of acute psychological collapse or under calculated intent. In Lee’s case, prosecutors argued her actions were planned — citing purchases, travel arrangements, and attempts to flee — while the defense framed them as part of an intended murder-suicide.

2. Migrant Stress and Social Isolation

Research from the New Zealand Ministry of Social Development and academic studies on migrant mental health consistently show heightened risks of depression, social withdrawal, and economic instability among recent immigrants without support networks.

Lee lost her husband only a year after relocating. She was raising two children alone, financially strained, and culturally isolated. That doesn’t remove culpability, but it provides context for understanding the conditions in which psychological decline can go unnoticed.

3. Grief, Identity Collapse, and Untreated Mental Illness

The death of Lee’s husband appears to be a pivot point. According to her mother’s statement to prosecutors, Lee expressed suicidal ideation around the same time. Clinically, this aligns with patterns observed in complicated grief — a condition associated with impaired decision-making, dissociation, and an increased risk of extreme actions.

However, no evidence currently indicates she sought or received psychiatric care. The absence of formal intervention is itself a critical part of the story.


What Independent Experts Typically Say About Issues Like This

Analysts generally note that child-homicide cases involving a parent fall into several recurring categories: prolonged mental-health deterioration, perceived hopelessness, retaliatory motives, or a distorted belief that death is “protective.” In cases linked to suicidal ideation, researchers often point out that the parent may view the children’s deaths as part of a joint departure from life — a pattern sometimes seen in cases after sudden spousal loss.

Legal scholars often highlight another dimension: the gap between mental illness that is visible and mental illness that is hidden behind functional daily behavior. Many individuals who commit child-homicide maintain outward routines while privately unraveling.

Criminologists also emphasize that concealment after the act — such as hiding bodies — typically indicates a conflicted state of mind rather than a detached, calculated one. At the same time, prosecutors uniformly treat concealment as evidence of intent and awareness of wrongdoing.

This tension between psychological collapse and legal interpretation is common in cases like Lee’s.


What Happens Next

Lee’s life-sentence marks the legal endpoint, but several broader developments may follow:

  • Public inquiries or academic reviews could examine how warning signs were missed, especially the period after her husband’s death.

  • Child-welfare advocates may push for stronger early-intervention policies for bereaved or isolated parents.

  • Mental-health discussions around migrant families could gain more prominence, particularly regarding access to support services in New Zealand.

  • South Korea and New Zealand may revisit extradition frameworks, since Lee remained undetected overseas for years.

  • The storage-unit discovery may also prompt reviews of auction processes for units containing potentially sensitive materials.

This case is legally closed, but socially and psychologically, it leaves a long tail of unanswered questions.

FAQ / People Also Ask

Why did Hakyung Lee kill her children?

Court documents suggest a mix of suicidal ideation and overwhelming stress, but prosecutors argued the killings were planned rather than impulsive. The full psychological picture remains incomplete.

How were the bodies discovered?

A family purchased the storage unit at auction and found the suitcases inside. The remains had been hidden for four years.

Was mental illness part of the case?

Lee’s mother said she had expressed suicidal thoughts after her husband's death, but no formal psychiatric evaluation from that period has been publicly reported.

Why did she flee to South Korea?

Prosecutors argued she had prepared an escape plan before the murders. She changed her name after arriving in Korea.

Could this case lead to policy changes?

Possibly. Cases involving parental mental health, migrant support gaps, and unnoticed psychological crisis often lead to after-the-fact scrutiny.
