He's testified the argument, which according to Advocate Matthys Combrinck was about Teresa's weight and the fact that Marli's parents wanted her to tone down the relationship with Reade-Jahn as they felt it was too serious, had occurred prior to the attack which claimed the lives of Martin and Teresa van Breda and their other son in January 2015.
Marli van Breda was seriously injured in the attack.
James Reade-Jahn sent Marli van Breda a potentially damning Whatsapp message on 10 January 2015, about a week before the attacks, which sparked police interest.
