‘A Mafia-Style Execution’: Inside the Murder That Shook the Madlanga Commission

South Africa, on Friday night, was stunned when news broke out of something that has become chillingly familiar: another whistle-blower, another assassination, another investigative commission thrown into crisis. But even by the country’s grim standards, the killing of Marius “Vlam” van der Merwe, who was also Witness D at the Madlanga Commission, has sent shockwaves through law-enforcement agencies, civil society and Parliament and raised urgent questions about whether the state can protect those who dare to expose criminality in its ranks.

Van der Merwe, a key witness before the Madlanga Judicial Commission of Inquiry into Criminality, Political Interference and Corruption in the Criminal Justice System, was gunned down outside his Brakpan home on Friday evening. He had barely stepped out to open his gate when assassins armed with an AK-47 opened fire.

His wife, seated beside him in the car, survived. Nothing was stolen.

The message was unmistakable.

A Hit, Not a Robbery

Late on Friday night, the South African Police Service (SAPS) confirmed what many already feared. “Evidence gathered at the scene confirms an AK-47 automatic rifle was used in the commission of the crime,” SAPS said, after crime-scene experts spent hours combing the blood-stained driveway.

The use of a military-grade weapon, officers say, rules out a random attack.

According to a preliminary SAPS briefing, Van der Merwe arrived home just after 20:30. As he stepped out to open the gate, gunmen ambushed him, firing multiple rounds into his upper body. His firearm, cellphone and wallet were untouched.

Police have now launched a manhunt not only for the hitmen, but also for the person who ordered the killing, a rare public admission that investigators believe the assassination was commissioned.

National Commissioner General Fannie Masemola is expected to personally brief Justice Mbuyiseli Madlanga, in what insiders describe as an “emergency engagement” to review safety protocols for all Commission witnesses.

Masemola has already instructed NATJOINTS to convene urgently. “We must improve and enhance the safety and security of commission officials as well as all witnesses,” he directed.

Hours after the SAPS statement, the Commission released its own, terse but heavy with emotion.

“We note with profound sadness the brutal killing of one of our witnesses,” spokesperson Jeremy Michaels said. “The Commission extends its deepest condolences to the Van der Merwe family.”

A longer response will follow, but officials privately concede the assassination has rattled the inquiry to its core. Witness D had given evidence central to allegations of criminal infiltration inside the Ekurhuleni Metro and its police department, the type of testimony that makes men targets.

One senior source described the mood as “deeply shaken,” adding: “People are terrified. Some are considering withdrawing.”

‘South Africa Is Becoming a Mafia State’

Reaction from political parties and civil society was swift and scathing. ActionSA was among the first to respond, calling the murder “yet another unmistakable sign of South Africa’s descent into a mafia state.”

“Whistle-blower protection can no longer be something government kicks down the road,” said MP Dereleen James. “We cannot reconcile the fact that those most vulnerable remain exposed to such fatal risks.”

The statement is a damning indictment of a system that routinely leaves whistle-blowers, the lifeblood of accountability, to fend for themselves.

The Forum for South Africa (FOSA) went even further, accusing the Commission itself of failing in its duty of care.

“This tragic incident represents a grave failure in ensuring the safety and security of individuals who come forward,” FOSA said. “Proper attention and resources should have been prioritised towards witness protection.”

FOSA warned that millions of rands have already been spent on the Commission. The basics, keeping witnesses alive, were not secured.

A Pattern South Africa Knows Too Well

For many South Africans, the killing of Van der Merwe evokes painful memories:

• Babita Deokaran, assassinated after blowing the whistle on Gauteng health tenders.
• Charl Kinnear, murdered while investigating gun-licence syndicates.
• Lt-Col Frans Mathipa, executed in 2023 after probing corrupt police officials.

In each case, witnesses died before their evidence could reshape the system.

And in each case, the state promised reforms.

Yet today, another witness is dead.

A Commission Under Threat

The Madlanga Commission was established to expose the rot inside South Africa’s criminal justice system: political interference, compromised police officers and corrupt networks operating with impunity.

Van der Merwe’s assassination, brazen, targeted and professional, suggests those networks are fighting back.

As one legal expert put it: “You do not execute a witness with an AK-47 unless you are confident the system won’t catch you.”

SAPS has promised a “full manhunt” for the shooters and the mastermind. NATJOINTS will meet over the weekend. Justice Madlanga will receive a personal briefing.

But the deeper question remains: how many witnesses will still come forward?

And how many will stay silent if they believe testifying is a death sentence?

South Africa’s democracy is often described as fragile but resilient. But resilience has its limits. When a witness is executed outside his own home with his wife watching, the message is meant for every South African considering speaking up.
