Van Breda: DNA analyst explains process of getting samples from scenes
Lieutenant Colonel Sharlene Otto is the 44th witness to be called to testify in the trial.
CAPE TOWN - A DNA analyst was called to the witness stand in the trial of murder accused Henri van Breda. It emerged in the Western Cape High Court earlier on Monday that over 200 DNA samples were taken from the scene where three members of van Breda's family were killed in 2015.
His younger sister was also seriously wounded in the attack at the family's Stellenbosch home.
Lieutenant-Colonel Sharlene Otto is the 44th witness to be called to testify in the trial.
She took the court through the process involved in collecting DNA samples from crime scenes and how they are analysed.
She says they are guided by international standards, adding everything they do is in accordance with standard operating procedures.
In this case, she told the court, officials were tasked with analysing 216 DNA samples which Otto stressed was done with their strict and stringent quality control systems in place.
She adds analysts wouldn't know what case a sample comes from, explaining this is done so the process remains objective.
