According to Leigh-Anne Jansen, a reporter for South Africa's eNC News, Mngeni died shortly after 2pm local time at Goodwood Prison in Cape Town. South Africa's Department of Correctional Services are due to make a statement tomorrow.

Mngeni was found guilty of pulling the trigger and killing Mrs Dewani in the Gugulethu township near Cape Town in November 2010.
