Nicolette Lotter has told the Durban High Court that she did not know a lot about witchcraft, but from what she had seen in Harry Potter movies, she was definitely experiencing "something negative".
"When you look at Harry Potter movies, some things are negative and some things are positive, and what I was experiencing was something negative," she replied when Judge Shyam Gyanda asked how she had come to the conclusion that her family's domestic worker was dabbling in witchcraft against her.
Nicolette and her brother Hardus claim that her former boyfriend Mathew Naidoo manipulated them into believing that he was the "third son of God" and that God wanted their parents dead.
The state alleges that Naidoo and the siblings planned and committed the double murder of their parents to gain a share of the inheritance.
Hardus told the court that he had attacked his mother, Riekie, with a stun gun, hit her with his fists and sat on her for about 15 minutes before Nicolette stabbed her repeatedly.
He said he had strangled his father, Johan with an electric cord which he pulled around his neck for at least 20 minutes.
Nicolette said yesterday that she believed Naidoo was a "good guy".
Nicolette claimed that her parents did not know that Naidoo had moved into their home as he sneaked into her bedroom each night.
She claimed that God spoke through Naidoo and instructed her brother and her to steal their parents' ATM card to "teach them a lesson".
She added that Naidoo always gave the domestic worker a share of the money withdrawn, therefore she now believes that he was buying "witchcraft things" from her.
She alleged that, on Naidoo's instruction, she tried for two weeks to poison her father by putting 90% alcohol in his whisky.
Nicolette is expected to continue in the witness box when the trial resumes in March next year.
