Brigadier Mathe provides more details about the murder
Discussing the arrest of Sotheni, Brigadier Mathe said he was a former member of the South African Police Service, joining in 2005. In 2010, he joined the elite Special Task Force and resigned in 2019, when he went into the private sector.
Brigadier Mathe also said that according to investigations conducted by the newly formed Madlanga Task Team, Sotheni had been following van der Merwe since his testimony.
On the evening of the murder, he was travelling in a vehicle with Wiandre Pretorius when they approached van der Merwe. Pretorious recently killed himself after he was linked to the murder. Brigadier Mathe said that Sotheni shot Witness D from the vehicle, and given his training as a Special Task Force member, only he could have pulled it off.
The men then fled in the Suzuki Swift they were travelling in, which allegedly belongs to Sotheni’s girlfriend. The gun used to commit the murder is still missing, but police confirmed that Sotheni was found with several rounds of ammunition on the day of his arrest.
Brigadier Mather also confirmed that Sotheni was recently employed as a bodyguard for a prominent family in Houghton Estate, but police believe he was hired to kill Witness D as a side job, due to his skills and experience as an expert marksman.
