Hardus and Nicolette Lotter's original attorney Danie Grundlingh has written a book about their murder of their parents.

Called “Innocent Acts of Evil”, Grundlingh said it was “the story about the Lotters' murders, as seen through Hardus Lotter's eyes”.

The book was written and printed long before the trial of the Lotter siblings, and corroborates evidence given in court by clinical psychologist Professor Laurens Schlebusch.

“The book explains most of the public's unanswered questions and can maybe change the public perception of the siblings' actions and can also enlighten society about cultism, brainwashing and fanaticism,” Grundlingh said.

The Lotters and Nicolette's ex-boyfriend Mathew Naidoo were convicted last week of murdering Johannes Petrus “Johnny” Lotter and Maria Magdalena “Riekie” Lotter in their Durban home on July 19, 2008.

On Monday, Naidoo received a double life sentence in the Durban High Court for his part in the killing, while Nicolette was sentenced to in effect 12 years' in jail, and Hardus to in effect 10 years.

During the trial, the brother and sister told the court they had acted at the behest of Naidoo, who had convinced them he was the third son of God. - Sapa
