Mrwetyana, a first-year film and media studies student was last seen alive on August 24 on her way to collect a parcel at the Clareinch Post Office in Claremont, where the accused worked.
Khanya wrote an open letter to her sister, saying: “What haunts me the most isn’t the fact that you’re gone and taken away from us so soon, it’s the thought of the fear and pain you experienced all alone. I’m so sorry.
“Now we hold on to the memories we shared together and the thought of what could’ve become of you had that man not violated you.
“Uyinene, you’re still my baby sister and always will be. I love you so much. Fly away my butterfly.”
Three private investigators, including Noel Pratten, who was involved with the search and discovery of slain Meghan Cremer, joined the search for Mrwetyana over the last week.
In the early hours of Friday, police and the provincial Flying Squad arrested the man who allegedly confessed to raping Mrwetyana before killing her and dumping her body.
Detailing the events leading to Mrwetyana’s death, prosecutor Nomnikelo Konisi said the young woman had gone to the post office after 2pm; the accused told her to return later as the power was off.
When Mrwetyana returned, the accused was alone and he allegedly accosted her and locked them in the building before raping her and bludgeoning her repeatedly with a scale.
The court heard Mrwetyana had fought hard for her life.
