These are a few high profile cases I have been involved in:

- 2000 – the Fairhead double murder of the mother and daughter (Fish River) – Seafield CR 15/01/2000 (Lab 7191/00)
The consequent appearance in “Criminal Minds” – a series on television
- 2001 – The murder of Me Marike de Klerk – Table View Cas 60/12/01 (Lab 107767/01)
- 2004 – The serial rapist (“Navy seaman”) – Nyanga cases and others

I have successfully completed 96 proficiency tests:

Whether I live out my passion in the performing of DNA Casework, or whether it is the transfer of information to clients or even mentoring and supervising younger and less experienced colleagues – this is the work I love and enjoy:
To fulfil the dream of making a difference in South Africa.
