The appellant, a police officer, was charged with the murder of Ludwe Golotile, who was shot and killed during a police crime-prevention patrol in Samora Machel, Nyanga, on 20 January 2007. No eyewitness saw the appellant shoot the deceased. The State’s case relied primarily on circumstantial evidence, especially ballistic evidence allegedly linking a bullet and cartridge found at the scene to the appellant’s service firearm. Serious discrepancies emerged regarding the recovery, preservation, recording, and conveyance of the ballistic exhibits, including inconsistent exhibit numbers and uncertainty about whether the items tested were those found at the scene.
