CAPE TOWN - The prosecution against family axe murder accused Henri van Breda has again emphasised the lack of practical experience of a defence DNA expert.

Prosecutor Susan Galloway has concluded her cross-examination of Antonel Olckers.

Olckers has been testifying on the scientific validity of DNA evidence presented by the State.

Galloway has again brought up the fact that Olckers has never worked in a forensic laboratory. Olckers has mainly academic and administrative experience.

This is an important aspect as Olckers has testified the police forensic lab where the DNA samples had been tested did not comply with certain standard operating procedures.

Olckers has argued because of this, more than 40 of the samples submitted by the state, are invalid.

Galloway has told the court Olckers made similar findings in two previous court cases she'd worked on years ago and in both those cases the court criticised Olckers' findings and accepted the state's.

Van Breda stands accused of the murder of his parents and older brother, and the attempted murder of his younger sister.
