Brakpan, Gauteng — A crucial whistleblower in the Madlanga Commission, identified in testimony as Witness D, was shot dead in Brakpan on Wednesday night in what investigators believe may have been a targeted execution linked to explosive evidence he provided against senior law-enforcement officials.
Police confirmed that the witness, whose real name is Marius van der Merwe, was gunned down outside his family home shortly after 9 pm. He died at the scene. A manhunt has been launched for the assailants and detectives are investigating whether the murder is connected to his testimony, which implicated high-ranking members of the Ekurhuleni Metropolitan Police Department.
What Witness D Revealed Before the Madlanga Commission
Before his death, Witness D delivered some of the Commission’s most damning testimony. He alleged that suspended EMPD deputy chief Julius Mkhwanazi and several officers were involved in the torture and killing of a Brakpan robbery suspect during a 2022 raid. According to his account, the suspect died after being suffocated with a plastic bag during interrogation after allegedly offering a bribe.
Witness D told the Commission that Mkhwanazi ordered officers to dispose of the body and ensure the death left no trace. He described loading the corpse into his bakkie and dumping it in a Nigel dam under instruction, naming officers, SAPS affiliates and a police informer allegedly involved in the cover-up. His testimony formed a central pillar of the Commission’s investigation into organised criminal behaviour and internal corruption within law-enforcement structures.
Why His Assassination Is Critical to South Africa
The killing directly challenges South Africa’s ability to protect whistleblowers who expose criminality within the state. It strikes at a long-standing national vulnerability where witnesses in corruption and organised-crime matters are targeted before cases reach prosecution. This pattern has been seen in municipal corruption inquiries, gang-related investigations and previous commissions.
The Madlanga Commission represents one of the most significant attempts to dismantle police-linked extortion rings and violent criminal networks. The murder of a witness who provided testimony on torture, murder and a state-enabled cover-up raises urgent questions about whether the country can safeguard the individuals who make justice possible.
What the Killing Means for the Madlanga Commission
The Commission now faces a major setback. Witness D’s testimony implicated senior officials and outlined the mechanics of how criminality allegedly operates through state institutions. His evidence was considered pivotal in connecting high-ranking officers to violent activities, bribery and deliberate attempts to conceal unlawful killings.
If witnesses fear for their lives, the Commission’s flow of information may be severely compromised. South Africans following the inquiry have already expressed concern that the assassination could discourage others from testifying, weaken the Commission’s credibility and undermine efforts to expose entrenched criminal networks.
Government sources say the Commission will request an urgent briefing from intelligence officials. Civil-society groups have renewed demands for stronger witness-protection frameworks, noting that whistleblower killings erode public trust and weaken constitutional accountability.
Police are appealing for information as the investigation progresses.
