The holiday season is a time for joy and celebration, but for one South African family, it has been overshadowed by unspeakable tragedy.
Marius van der Merwe, a former Ekurhuleni Metropolitan Police Department (EMPD) officer and "Witness D" at the Madlanga Commission, was gunned down in front of his family on December 5.
What remained was a family suddenly standing inside a life they did not prepare for, a life without their provider, protector and anchor.
Van der Merwe, affectionately known as Vlam (flame) by his community, was more than a former officer; he was Superman, South Africans say, as tributes pour in for the family man whose life was tragically taken in the fight against corruption and illegal mining in his hometown of Brakpan.
Telling the truth in South Africa can be dangerous. Van der Merwe had received threats for months and survived an earlier attempt on his life in September. He chose not to accept police protection, a decision that sadly led to his death.
On that fateful Friday evening, as he came home with his wife and two young sons, armed attackers ambushed him.
How do I say goodbye?” A wife’s grief shared with the nation
As South Africans processed the news of van der Merwe’s murder, his wife Leanne turned to social media to share her grief. In a series of TikTok videos, she painted a picture of a devoted husband and father.
One heartbreaking montage shows him spending precious moments with his children playing on a farm, enjoying ice cream, and holding his son with pride. These tender memories stand in stark contrast to the brutal reality that his family now faces.
Leanne’s posts have resonated with the nation. “How do I say goodbye? How do I carry on, never seeing you again? I love you forever, babe,” she wrote in one caption. Her words, raw and unfiltered, reflect the anguish of a family robbed of its pillar of strength.
Van der Merwe was not just a father; he was the sole provider for his family. His death has left his widow and children, Grayson and Oliver, in an uncertain financial position. With school fees, therapy expenses, and day-to-day costs looming, the family faces a daunting road ahead.
In the face of tragedy, South Africans have come together to support the Van der Merwe family.
A crowdfunding campaign on BackaBuddy has been launched to ease their financial burden. The campaign goal is R100,000, and as of December 12, just three days after its creation, R9,137 has been raised.

Social media users have also lent their support to the campaign.
A moving post by TikTok user Carri-Ann Bloom captured the sentiment of many: “Witness D was murdered for telling the truth. Even a small donation can help his family now that their provider is gone.”
Van der Merwe’s death exposes the deep failures of a justice system that could not protect him.
As South African author Khaya Dlanga outrageously called out on X (formerly Twitter): “Criminals are so brazen in this country.
"The way they just killed Witness D when the whole country is paying attention to the commission… The casual arrogance is chilling.”
Loss doesn’t pause life; it forces life to continue under impossible conditions. Leanne and her children will need long-term support, therapy, school fees, medical costs, transport, and daily living expenses.
From here on forward, every sunrise will look different for the Van der Merwe family, quieter, heavier, edged with the kind of pain only sudden loss can carve.
But grief, as cruel as it is, also teaches us that love doesn’t end; it changes shape.
And maybe that’s where their strength will come from in knowing South Africans are holding space for them, carrying their story, and refusing to let the life Marius lived, and the truth he stood for, fade into silence.
Beyond providing financial aid, this moment demands broader reflection: How can society better protect those who pursue justice?
How do we hold systems accountable for their failures? And how do we honour the legacy of heroes like Van der Merwe and many others, who gave everything for the truth?
