My one-year-old was happy and healthy – I still don’t understand why he died
Sudden Unexplained Death in Childhood (SUDC) is the unexpected death of a child aged one to 18 that remains unexplained, affecting roughly 40 children every year in the UK. According to the charity SUDC UK, this frequency is comparable to one or two seemingly healthy children dying every fortnight. The case of Albie, a boy from Inverness who died in April 2023, illustrates the standard police protocols and the complex grieving process associated with these losses.
What is Sudden Unexplained Death in Childhood (SUDC)?
SUDC refers to a death that occurs without a clear medical cause after a thorough investigation. According to SUDC UK, these children are often healthy and typically pass away in their sleep. There is currently no known way to predict or prevent these events.
In the case of Albie, who died on April 28, 2023, his mother, Daisy McKenzie, reported he had been “happy and healthy” and had fallen asleep after a normal day. Following a post-mortem examination at a hospital in Aberdeen, medical professionals confirmed the cause of death as SUDC. This diagnosis means that despite medical scrutiny, no explanation for the death could be found.
Why do police investigate SUDC cases?
Police involvement is standard procedure in the UK when a child dies unexpectedly. According to SUDC UK, this does not mean the parents are under suspicion. The goal is to rule out foul play and ensure a legal record of the death is established.
Daisy McKenzie told Metro that this process was “confusing and overwhelming.” Police officers arrived at her Inverness home shortly after paramedics declared Albie dead. As part of the evidence-gathering process, officers removed items from the home, including Albie’s bedding and a rainbow pillow. McKenzie noted that while the officers were understanding, the experience made her feel as though she were under suspicion.
How does the diagnostic process work for unexplained deaths?
When a child dies unexpectedly, the body is typically moved to a forensic facility for a post-mortem. In Albie’s case, his body was transported from Inverness to Aberdeen, a journey of over two hours. The McKenzie family was unable to see their son for three weeks while the examination took place.

The process involves taking statements and blood samples from the parents to rule out genetic or environmental factors. For Albie’s family, the police investigation remained open for nearly three years due to case backlogs before officially closing, which McKenzie described as a “relief.”
How do families manage the psychological impact of SUDC?
Grief following an unexplained death often lacks a linear timeline. Daisy McKenzie described her emotional state as “messy and jumbled,” stating that she frequently experiences multiple conflicting emotions in a single day.
The impact extends to siblings. Albie’s older brothers—Caden, Jacob, and Milo—received counseling through their school, which allowed them to leave lessons as needed to cope with the loss. Caden, now 18, marked the loss by tattooing Albie’s date of birth on his forearm.
McKenzie also reported a phenomenon where happiness and sadness coexist. This occurred when she gave birth to her son, Bhodi. She admitted to being “extra cautious” and placing Bhodi on “red alert” as he approached the age Albie was when he died, leading to frequent doctor visits to ensure his health.
What are the best ways to maintain a connection with a lost child?
Families often use concrete rituals to integrate the memory of a lost child into daily life. The McKenzie family employs several specific strategies:
- Annual Traditions: Buying a Christmas bauble for Albie every year.
- Physical Reminders: Using a teddy bear made from Albie’s baby clothes during holidays.
- Environmental Tributes: Writing Albie’s name in the sand at Nairam Beach.
- Charitable Projects: Raising money for community gardens, reflecting Albie’s love for the outdoors.
