On the face of it, the evidence is overwhelming, yet Tladi's family have waited the better part of a year to see any progress in the Independent Police Investigative Directorate's inquiry into his death.
To compound the family's distress, the alleged killer returned to work at his police station shortly after Tladi's death.
Ipid say the docket is ready but that a decision has been delayed because the ballistics report had not been completed.
The case is, in many ways, symptomatic of our justice system where the gears grind slowly - unless the target is a perceived political foe of someone in power.
This does nothing but undermine confidence in law and order. If the authorities cannot swiftly deal with the death of a police officer allegedly by a colleague, what confidence can we have in the broader fight against crime?
In the past year some 40 police officers have been killed and many more will fall if these crimes are treated the way Tladi's killing has been.
"We don't feel okay. We still don't sleep. Nothing has changed because we are still waiting for answers," says his sister Tshidi.
Tladi, one of these fallen 40, deserves better and so does his family.
