A Delmas husband who confessed to attacking and killing his wife with a spanner and knives in a fit of anger will hear his fate in January next year.

Acting Judge Peter Mabuse on Monday postponed the trial of Ockert Daniel (Ockie) van den Berg (43), to 12 January next year for judgment.

Van den Berg last week told the Pretoria High Court he was so angry after his wife Christa told him she was tired of him, had another man and that their youngest son was not his, that he grabbed a shifting spanner and hit her until she was dead.

He also stabbed her in the neck and back with two knives, but afterwards pulled them out "because it did not look good".

Van den Berg said that afterwards he hit his son Jacques on the head with the spanner, to make it appear as if housebreakers had killed his wife and attacked his son.

Prosecutor Corlie Bouwer argued that Van den Berg had the direct intention to kill his wife and son and should be convicted of murder and attempted murder.

Tired of being belittled and referred to as retarded by his wife, he had attacked her in her sleep as an act of punishment and revenge, Bouwer argued.

Defence counsel Johan Gaum argued that Van den Berg should be acquitted because of "criminal incapacity".

Van den Berg had never been violent towards his wife or children in their 19 years of marriage. His wife had not only admitted to having an affair and a child with another man, but also attacked his manhood by telling him he needed a penis enlargement.

Van den Berg, with his sub-normal intelligence, was of an "immature age", and could not react normally to the provocation and humiliation his wife had subjected him to, he added.
