A South African paramedic describing the aftermath of the attack on the wealthy Van Breda family said it was the worst thing he had seen in his 39-year career.
Blood ran like a waterfall down the stairs, testified now-retired Christiaan Koegelenberg.
More than three years after Mr Koegelenberg walked into the midst of that horrific scene, a judge has found the familys only surviving son, Henri, guilty of using an axe to kill his mother, father and brother.
His younger sister managed to survive the attack in their home in a gated housing estate in Stellenbosch in South Africas wine region.
Van Breda, who was 20 at the time of attack, is due to be sentenced soon - but the motive for the horrific murders is still not known.
Some believe he did it was to inherit his fathers multi-million dollar estate, but this was never proven.
Whatever the motive, investigators and South Africans alike have been left shocked by the violent nature of the attack.
Martin and Teresa van Breda were found in a pool of blood on the first floor of their home on the De Zalze Golf Estate on the morning of 27 January 2015.
Close by was the body of their 22-year-old son Rudi and their 16-year-old daughter Marli, who was fighting to stay alive. Van Breda, meanwhile, had sustained only minor injuries.
The attacker had moved quickly and determinedly.
The Western Cape High Court agreed that the extent of the injuries meant that the assailant had intended to kill.
Van Breda gave a statement to police soon after the incident saying that a well-built black intruder was to blame.
He described a man wearing gloves and a balaclava breaking into the family home.
