On 7 May 2019 in Calitzdorp, Western Cape, the appellant, Conrad Gysman, fatally stabbed 19-year-old Sonia Saaiman (the deceased) in the neck. An eyewitness, Mr Phillipus Fortuin, testified that he accompanied the deceased to the appellant's house to collect money. Upon arrival, the deceased and her mother knocked on the appellant's door, leading to a heated argument when he opened it. The appellant asked the deceased's mother, 'are you taking me for a fool,' turned around, retrieved an object, and when he turned back, the deceased pushed her mother and was stabbed in the neck by the appellant. The uncontested postmortem report confirmed the cause of death as a stab wound to the left lateral neck. The appellant's version was that he was sleeping after consuming alcohol, was awoken by a noise he believed was an intruder at his window, grabbed a knife, and stabbed blindly through a towel covering the window, later learning he had struck the deceased. The trial court rejected the appellant's version as so improbable it could not be reasonably possibly true.
