When Jason Rohde came under cross-examination in the Western Cape High Court on Wednesday, he seemed reluctant to wrap the cord of a curling iron around a police officer during a demonstration.He explained to the court that he did not want to hurt her.With the bathroom door of the Spier Hotel room in the courtroom, a Stellenbosch police colonel offered to be the model for the demonstration as prosecutor Louis van Niekerk asked Rohde to show everyone what he found on July 24, 2016.Dressed in a dark suit, Rohde left the stand and walked to the door.Van Niekerk said he must show how tight the knot was, as he had previously told the court the knot around her neck was tight.Rohde had testified on Tuesday that "the knot around her neck was very tight" and referred to a tight lasso.On Wednesday, he told Van Niekerk: "What I meant is that the tension around the neck was very tight," adding later that he could say that the "noose" was not loose.WATCH: Murder-accused Jason Rohde testifies about wife's deathHe appeared to hesitate with the cord and slowly wrapped it around the officer's neck.He apologised to her as he moved the cord around.When Van Niekerk asked if that was how tight it was, he said: "No, it's not. Because if I had to do the tightness..." before trailing off, pausing and then saying it wasn't slack.Rohde explained that he was not being evasive but could not demonstrate the knot because that had not been his focus.His focus had been on removing the cord."I am not being flippant, but why would I be studying the knot? What relevance to me is it how many times it is around her neck? I was in absolute shock. I wanted to get it off her neck."Rohde gave instructions to the model on the crouching position she should take to show how he found his wife. He also stepped in and crouched in front of the door.#Rohde Jason instructs model to crouch how he found Susan.

Otherwise it's not an affair."The trial is expected to resume on Thursday.
