Ernst Marais – Branch Manager & Investigator

Phone: 082 847 4727

I have a passion for people and to be able to help somebody in need brings me a lot of joy. I have 22 years of experience in the SA Police Service and ended my career in SAPS as a Branch Commander of the Detective Services.

5 Years ago I grabbed the opportunity to get more focused with Accident Reconstructions and Civil Litigation investigations. I left the Police Services to broaden my knowledge and ability to be of service to people affected by the wrong doings of a third party.

I work closely with Welmar O’Reilly, the Director of Quaestio Forensic Investigators, who has ample experience in this field.

As a Forensic Investigator, I have been working for Quaestio Forensic Investigators for  about 5 years. I was a detective with the South African Police for 16 years holding the rank of Captain.

My responsibility at the detective branch was doing the high profile cases including culpable homicide investigations.

Love doing the work we do at Quaestio Forensic Investigators – Investigating cases is something that is in your blood.

Anton Pretorius – Investigator / Assessor

Phone:  074 584 2221

After I  finished my studies in BA Psychology at UFS, I taught for about two years, whilst doing my HED through UNISA.  I joined Sanlam as an insurance representative in 1993, where for the next 12 years I gained valuable experience in the life insurance industry. I later became an independent life insurance broker.

I recently joined Frans Burger in Bloemfontein to assist him with the EY contract. Even though I am relatively new in this field of business, it is invaluable to me to work closely with somebody of Frans’s calibre, who has such vast experience in this field.

I am a people-orientated person with a strong sense of fairness and justice. In the past I have had personal experience of the trauma and life-changing impact that an accident can have on people, therefore it gives me great job satisfaction to assist people in need and to achieve a successful result on their behalf.
