From Down the Rabbit Hole by Oxpeckers 2013:
Rogue South African trophy hunters are directly involved in ‘a mad scramble’ to poach rhinos and get their horns out of the Kruger National Park, according to reliable intelligence sources.

Documents in the possession of Oxpeckers show the errant trophy hunters are supplying Mozambican poachers with ammunition and helping them to sell the horns illegally. They manage to avoid apprehension by bribing local officials and courting influence with Mozambican politicians.
The hunters run safari outfits along the south-eastern border of the Kruger, and they gain access to the park through gaps in the fence between the two countries. They cannot be named owing to the seriousness of the trafficking allegations against them.
They operate in the vicinity of Corumana dam and the former Magud headquarters of Mozambique’s Renamo movement. Corumana dam is a popular destination among birders and fishers, and is being expanded to supply water to Maputo about 30km away.
“During the day Corumana is serene, but at night you hear the traffic of boats with engines plying their illegal trade. There is a mad scramble to get as many rhino horns out of the Kruger Park as possible,” said a fisherman who visited the area recently.
Independent intelligence sources have been monitoring the hunting operators since 2011. They say they have passed their information on to anti-poaching authorities in South Africa, but have received no feedback on whether it has been followed up.
Confidential documents reveal that the kingpin is a safari outfitter with a hunting concession close to Corumana dam. He regularly hunts wildlife without permits, according to intelligence, and smuggles animal trophies and rhino horns in a hidden compartment of his vehicle.
The documents implicate him directly in the poaching of rhinos in southern Kruger and the smuggling of their horns to Maputo and South Africa. He is also accused of bribing the local police chief to drop charges against poachers working with him.
Other hunters fingered in the investigation since 2011 include a safari outfit previously caught luring lions out of the Kruger for “canned” hunts, and another outfit previously implicated in ivory smuggling in Namibia. The network has formed strategic alliances with politicians and prominent business in Mozambique for protection, according to the intelligence.
