Cape Town - The attacker behind the Van Breda axe murders possibly dragged and shoved Rudi’s body around to show his anger, blood spatter expert Captain Marius Joubert testified on Thursday.During cross examination by Advocate Pieter Botha over what triple murder accused Henri van Breda would gain from moving his 22-year-old brother from where he was attacked on the bed, Joubert conceded that he didn’t know.“There was a lot of anger towards Rudi, in my opinion,” Joubert told the court.“It is possible that the attacker showed his anger by dragging and shoving his body around.”Rudi was according to State witnesses and evidence the first to die.Pathologist Dr Daphne Anthony in her testimony postulated that Rudi's injuries showed he had been lying on the right side of his face. Trauma to head means he was aware of what was coming and had raised his hand in an attempt to ward off the attack, resulting in incised defensive wound on little finger.Captain Marius Joubert, blood spatter expert, is back on the stand today for further cross-examination by the defence.

Joubert found this unlikely, explaining that the damage to the staircase wall was caused by axe being hit, not thrown, from only 1.5m away.He demonstrated how Henri would have been close enough to wield the axe at the intruder.“Why would you throw an axe at someone when you can hit them directly with it?” he asked.Botha, however, asked if Joubert had known Henri’s position, how many rotations the axe had made or how hard it had been thrown. Joubert conceded that he didn’t.Henri also could not recall where on the stairs he had been at the time of hurling the axe.The trial resumes on Monday.AS IT HAPPENED: Van Breda axe murder trial day 39Henri van Breda's murder trial resumes in the Western Cape High Court for day 39 of the proceedings.
