Matlala trial: New witness testifies in high‑profile case

Johannesburg – The high‑profile trial of Vusimuzi “Cat” Matlala and four co‑accused has entered a new phase as a fresh witness took the stand on Wednesday. The appearance comes after the prosecution briefly closed its case in the complex “trial within a trial” that has dominated South African headlines since the alleged 2024 murder of engineering consultant Armand Swart.

Background to the Matlala trial

The case began in early 2025 when police arrested Musa Kekka, the alleged mastermind behind Swart’s killing, alongside Matlala, who is accused of orchestrating the attack. The prosecution alleges that the group planned to eliminate Swart because of a disputed contract with a state‑owned utility. The trial, presided over by Justice Thandiwe Mthembu at the Johannesburg High Court, has been marked by procedural twists, including a separate “trial within a trial” to determine whether evidence gathered during the arrests was lawfully obtained.

South Africa’s Constitution guarantees the right to a fair trial, and the courts have been vigilant in ensuring that any forensic or electronic evidence complies with the Protection of Personal Information Act (POPIA) and the Criminal Procedure Act. The “trial within a trial” is a legal mechanism that allows the court to assess the admissibility of evidence before the substantive charges are heard, a step that has delayed the main proceedings for months.

Defence calls on C‑Track expert

On the defence side, the spotlight fell on Eric Deysel, a senior consultant for C‑Track, a company that provides GPS and telematics solutions to law‑enforcement agencies across the continent. Deysel was called to testify on behalf of Musa Kekka, the first accused, with the aim of undermining the prosecution’s claim that police vehicle logs prove a coordinated raid on Kekka’s residence.

During his testimony, Deysel explained how C‑Track’s tracking system logs the movement of each police vehicle in real time, assigning a unique identifier to every unit. He presented data showing that, on the night of the arrest, sixteen police vehicles were recorded as having entered the vicinity of Kekka’s home. Crucially, Deysel highlighted a discrepancy: nine of the ten vehicles reported at “8th Road” also appeared on the log for “5th Road,” suggesting possible duplication or mis‑recording of routes.

“I managed to identify ten vehicles that reported at 8th Road and sixteen that reported at 5th Road,” Deysel told the bench. “However, nine of those ten vehicles also appeared on the 5th Road log, which raises questions about the accuracy of the data and, consequently, the reliability of the evidence derived from it.”

Implications for evidence admissibility

The defence’s strategy hinges on the argument that if the tracker data is unreliable, any statements or confessions obtained during the arrest could be deemed tainted. Under South African law, evidence obtained through an unlawful search or seizure can be excluded under Section 35(5) of the Constitution, which protects individuals from self‑incrimination and unfair investigative practices.

Legal analysts note that the outcome of Deysel’s testimony could set a precedent for how digital tracking evidence is treated in future criminal cases. “This is the first time we are seeing a defence team directly challenge the integrity of police telematics data in a high‑profile murder trial,” said Advocate Lindiwe Nkosi, a criminal law specialist. “If the court finds the data flawed, it may force the prosecution to rely on alternative evidence, such as witness statements or forensic analysis, which could shift the balance of the trial.”

What lies ahead for the Matlala trial

The court is scheduled to reconvene on Monday morning, when the prosecution is expected to resume its case after the brief closure. Prosecutors have indicated that they will call additional forensic experts to corroborate the tracker data and to present ballistics reports linking the firearms recovered from the accused to the crime scene.

Meanwhile, the media continues to monitor public reaction. The murder of Armand Swart, a prominent engineer involved in major infrastructure projects, sparked outrage in the engineering community and prompted calls for stricter security measures for professionals working on high‑value contracts.

For the defendants, the stakes are equally high. A conviction could result in life imprisonment, given the aggravated nature of the alleged attempted murder. Conversely, a successful challenge to the admissibility of key evidence could lead to a dismissal of the most serious charges, leaving only lesser offences to be tried.As the Matlala trial progresses, observers will be watching closely how technology, constitutional rights, and traditional investigative methods intersect in South Africa’s justice system.
