Murder accused Henri van Breda didn't check his family's house for any other intruders after the deadly attack on his relatives.
This has emerged during his cross-examination in the Western Cape High Court.
He is accused of the murder of his parents and older brother and the attempted of his younger sister in their Stellenbosch home in January 2015.
He claims that an intruder was responsible and that he heard the voices of at least two intruders that night.
“There’s numerous spots in the house where they could have been. I didn’t check.”
Van Breda, aged 23, has told the court that he didn't think about checking whether the intruders were still in the house after managing to fight off one of the men.
Prosecutor Susan Galloway has pressed him about this.
He responded: “I was recovering from a large amount of trauma. I was not thinking clearly. As soon as I thought they were out of the house and gone, I decided to get the emergency services.”
Galloway has also questioned why the intruders didn't steal anything from the house.
She will continue cross-examination on Monday.
