CAPE TOWN - The National Prosecuting Authority (NPA) has explained that it took over a year to finalise its case in the van Breda family murders as investigators wanted to make absolutely sure that the evidence was strong enough to proceed.

Twenty-one-year-old Henri van Breda appeared in the Stellenbosch Magistrates Court today and was released on R100,000 bail.

He is accused of hacking to death his mother, father and older brother at the family's De Zalze home outside Stellenbosch in January last year.

His younger sister, Marli, was seriously wounded but survived the attack despite her jugular being severed.

The NPA's Eric Ntabazalila says van Breda is not considered a flight risk.

"Since the incident happened on 27 January 2015, he has cooperated and has not absconded. Whenever he was supposed to meet with the investigating officer, he has met with them."

The State believes DNA evidence will prove van Breda killed his parents and his older brother with an axe.

The prosecution revealed DNA analysis proves blood found on van Breda and his clothes belonged to his murdered parents and older brother.

Post-mortems show Martin, Teresa and Rudi Van Breda died due to head injuries.

The State claims an axe and a kitchen knife were used to commit the murders.

Both weapons were found at the scene.

Investigations have also found van Breda's wounds were allegedly self-inflicted and he had tampered with the crime scene before police arrived.

LISTEN: Van Breda granted bail of R100,000.

Pre-trial proceedings will begin on 9 September in the Western Cape High Court.
