Kayla was an assassin from SOMBRA's "next level" program sent to kill Prince Abioye. She had shoulder-length curly blonde hair swept to the left, and also had yellow eyes due to being experimented upon. At the time of her death, she donned a white sleeveless shirt with a gold pin on it, blue denim pants, and a dark blue scarf with white triangle patterns.
Kayla was found in a Zulu village just fished out of a well with her hands and feet tied together. Angela confirmed her cause of death was by drowning. Furthermore, she was knocked out then tied up before being thrown in. Because of that, she managed to find traces of melktert between the victim's skin and the rope. According to Dupont, melktert translates into milk tart, and is a local dessert made from milk, flour, sugar, and eggs. This meant the killer ate melktert.
Killer and motives
The killer turned out to be the victim's ex-boyfriend named Kwanele Mthembu.
After denying involvement, Kwanele admitted he killed Kayla. After learning of Kayla's induced superintelligence, Kwanele wanted to be a SOMBRA assassin, but she said he was too old. Wanting to prove his worth for the organization, he tied Kayla up, drowned her in the well, and tried to murder Abioye. Judge Adaku sentenced him to 30 years in prison for the murder of Kayla Pieterse and the attempted murder of Prince Abioye.
- Kayla strongly resembles Natalie Dormer, an English actress.
- Also, her last name could be a reference to Sasha Pieterse, a South African-born American actress and singer-songwriter.
