The complaint she investigated
On 13 October 2021 three complainants laid an IPID complaint that officers had defeated the ends of justice over the Aeroton bust.
Maphosho testified that a Hawks chief and two officers complained to IPID against a group of senior officers; she registered the matter under the IPID Act and led the investigation from IPID's national specialised investigative team.
IPID never got the docket
She testified that the DPCI refused to hand over the case docket, and that escalations to senior management failed.
IPID, she said, investigated without the docket; her demand letters and escalations - including to the national DPCI head - did not produce it, and she conceded no criminal complaint was laid over the refusal despite the IPID Act allowing it.
Unaware of the forensic evidence
She conceded she had not seen the encrypted-chat and phone-tracking evidence Sebola later presented.
Had IPID known of the Threema and WhatsApp chats, Tumelo Nku's Durban trips and the May 2021 communications, she conceded, 'we were going to look at these things differently' and the investigation would not have unfolded as it did.
The 'informer' interview
She interviewed Tumelo Nku, who claimed to be a police informer but offered nothing she could verify.
Maphosho testified Nku spoke vaguely of working for a now-deceased general and of 'hacking', and conceded he was likely not a registered informer.
Complainants who were also suspects
She acknowledged IPID's complainants were themselves implicated, and that the referral memo gave a one-sided account.
Telling the commission 'we don't investigate our complainants', she accepted that many IPID complainants are themselves suspects, and that the referral had been written one-sidedly.
Conceding the arrests
Under questioning she accepted that the driver's arrest was premature - and ultimately that no one should have been arrested that day.
That concession cuts against IPID's framing that releasing the driver and a manager amounted to defeating the ends of justice.
The panel pokes holes in the probe (Day 116)
On her second day the commissioners questioned the thoroughness of IPID's investigation point by point.
Commissioners pressed Maphosho on conclusions they said the statements did not support - that the K9 unit was blocked from searching multiple containers (no statement said there was more than one), and that exhibit bags had been 'changed' (Warrant Officer Morris's statement said damaged bags were placed inside new bags, witnessed by the FSL case-management team). She accepted several points and defended others, maintaining there had been interference at the scene.
Recommended for action, then declined by the NPA
IPID recommended disciplinary steps and a prosecution referral; SAPS did not implement them and the NPA twice declined to prosecute.
Maphosho testified IPID referred the docket to the NPA recommending the prosecution of five officials - Maj-Gen Khan, Maj-Gen Kadwa, Brigadier Skhovela, Colonel Steyn and Lt-Col Sebola - for defeating the ends of justice. The NPA issued a certificate declining to prosecute (June 2024) and, on review, again found no reasonable prospects of success. Five years on, the R300m Aeroton bust remains unsolved with no convictions; everyone named is presumed innocent.
