A key witness is expected to testify, under police guard and anonymity, before the Moerane Commission on Friday.
The presentations by this witness will close off the current round of inquiry on alleged political killings in KwaZulu-Natal.
The commission drew attention earlier this week when it emerged that president Jacob Zuma might be linked in some way to the death of 89 people since 2014 which have received little to no police attention.
Thus far, presentations made by more than one witness have highlighted the existence of a tight network between police, politicians and hitmen all working together to suppress detractors and opponents of in-power figures.
Despite such damning allegations of police collusion, the South African Police Services (SAPS) and Independent Police Investigative Directorate (IPID) have yet to release comments on the matter.
The inquiry has requested that representatives of the two entities provide reasons as to their alleged failure to embody their constitutional mandate.
Similarly, parliament’s Portfolio Committee for Police has urged both the SAPS and IPID to respond to allegations that corrupt officials who commit assaults are not held to account.
