Mziwamadoda Qwabe took to the stand in the Western Cape High Court, sitting just metres away from Shrien Dewani, who is charged with conspiring with him and two others to kill Anni in November 2010.
Qwabe was sentenced to 25 years in jail for his role in the crime, in terms of a plea and sentencing agreement reached in August 2012.
Xolile Mngeni is serving life for pulling the trigger of the gun, while his accomplice Zola Tongo is serving 18 years in jail.
Dewani maintains he and his wife Anni were hijacked while being driven through Gugulethu, Cape Town, in a shuttle bus while on honeymoon on Saturday November 13, 2010. He was apparently forced out and the hijackers drove off with Anni. Anni’s body was found slumped over the back seat of the shuttle the next day.
The State alleges Dewani conspired with others to stage the hijacking.
On Monday, Dewani pleaded not guilty to the five counts against him, seeking to prove his innocence with a plea explanation.
He is charged with murder, kidnapping, robbery with aggravating circumstances, and conspiracy to commit these crimes. He is also charged with defeating the ends of justice.
