During the first week of May 2000, Judge Willie Hartzenberg and the crowded courtroom of Pretoria's High Court heard the grizzly confession of Johan Theron, a former information officer of South Africa's apartheid government's Special Forces. The small, balding, 57-year-old man told the court that he was involved in the deaths of more than 200 anti-apartheid political prisoners between 1979 and 1987. The deaths, he claimed, were merely a part of his job.
According to Theron, the executions of hundreds of prisoners were a solution to the increasing prison inmate population of several defense force camps. In fact, he told the court that the disposal of the prisoners was primarily his idea, one that he initially proposed to his superiors in 1979. Theron stated that he used various methods to kill the prisoners, including burning, beating, poisoning and strangulation.
One of Theron's acts took place in 1983 in northern Kwazulu-Natal, Africa. According to LoBaido's article The Secrets of Project Coast, Theron claimed to have been instructed by his superior, Dr. Wouter Basson, to tie up three prisoners to a tree overnight and smear their bodies with jelly-like lethal toxins. The primary aim was to test the toxic agent to see if it was capable of causing death. To Theron's dismay, the men did not die as easily as he expected.
The next day, Theron found the men still clinging to life. He decided to get rid of the men in another way. He loaded them into a small plane and flew off towards the ocean. According to an article by South Africa's Sunday Times, during the flight Theron claimed that he injected the three men with lethal muscle relaxants before dumping their bodies into the sea. Theron further stated to the court that a majority of his victims were disposed of in a similar manner, by dumping them into the water some 100 miles off the coast.
