Reeva Steenkamp's blood left an s-shaped trail in Oscar Pistorius's house caused by an arterial spurt, the judge in his murder trial was told on Wednesday.
“The serpentine or 's' shape - that's typical of what you would expect in an arterial spurting pattern,” blood spatter analyst Colonel Ian van der Nest told the High Court in Pretoria.
When Judge Thokozile Masipa asked for a definition of arterial, he replied: “arterial, from an artery”.
He began by explaining that the blood residue found on an armchair in a downstairs sitting room at Pistorius's home in Silver Woods estate, would have come from upstairs.
“The open area above the landing makes the area accessible to arterial staining if there is someone with an arterial spurt in that area,” he said.
