Botha was a highly regarded houndsman, and frequently led leopard and lion hunting safaris with his pack of dogs for his company Game Hounds Safaris.
A source who didn't want to be named told Netwerk24 that a group of hunters had gone for a walk on Friday afternoon when they suddenly came across a breeding herd of elephants.
A fourth elephant then lifted Botha up with her trunk, and another member of the group shot the elephant.
The story of Theunis Botha's death made worldwide headlines not only for the freaky circumstances of his passing but also his stature in the world of big-game hunting.
As the hunters began to shoot at the elephants they became alarmed causing them to charge at the hunters.
Big game hunter Theunis Botha was killed when the elephant he shot stumbled and fell on top of him.
News24 said Botha was well-known in Zimbabwe and his business basically revolved around getting rich Americans to go on his trophy hunts.
In Monteira hunts, hunters use large packs of dogs to drive deer and boar towards them, before opening fire on the animals. Scott van Zyl was leading a crocodile hunt in the Chikwaraka camp when he disappeared, the report noted.
DNA samples taken from contents found in the stomachs of two crocodiles that were shot during the search matched Mr Van Zyl.
