Don and Christelle Steenkamp

 Griquatown - The son of murdered Northern Cape farmer Deon Steenkamp, Don Steenkamp, is the only heir to the family's almost R23 million estate, it was reported on Wednesday.

According to Beeld newspaper his parents' firearms, including those believed to be the murder weapons, were also left to him.

Deon Steenkamp, 44, his wife Christelle, 43, and their daughter Marthella, 14, were shot dead on the family farm Naauwhoek on April 6, last year.

Beeld reported that Deon and Christelle had a joint will. The assets in the estate were worth R22 999 307 and the liabilities to a single bond account R620 779.

Some R6.7m cash was collected from Deon's policies. There was also a Naauwhoek trust with farms worth R7.6m and cattle to the value of R1.2m, which Don would inherit.

His sister would have inherited the Edelweiss trust that consists of farms worth R6.4m, cattle valued at R960 150, and her mother's jewellery. Now Don would also inherit her portion.

He would only inherit the estate once he turned 21.

A 16-year-old boy was arrested for the murders and has pleaded not guilty. The murder trial is scheduled to resume on September 2. - Sapa
