Two of five former Security Branch policemen applying for amnesty in connection with more than 40 killings, Capt Jacques Hechter and W/O Paul van Vuuren, on Monday and Tuesday testified how they abducted the three separately, imprisoned them on a farm near Pienaarsrivier in Northern Province, and tortured them before electrocuting them.
The victims were Jackson Maake (a double agent according to Hechter and van Vuuren), "cell leader" Harold Sefola and Andrew Makupe, "Maake's contact in Mamelodi".
On Tuesday Maake's mother, Elizabeth Maake, testified before the committee. On Wednesday it will hear the wife of Sefola and a relative of Makupe.
After that, the hearings will move on to the killing of ANC activist Jeffrey Sibiya, which Hechter and van Vuuren are expected to testify to.
Other incidents about which they will eventually testify include the killing of a policeman and his wife at Hammanskraal, and the blowing up of a Zozo hut in Mamelodi, Pretoria, when several people narrowly escaped serious injury or death.
Hechter will testify about the killing of nine people in KwaNdebele.
Hechter and van Vuuren have already testified about the attempted murder of current Deputy Education Minister Fr Smangaliso Makhatshwa and current North-West legislature Speaker Jerry Thibedi, both trade union activists in the '80s.
On Tuesday Mrs Maake told the committee Hechter and van Vuuren were lying in their testimony that her son was a police informant.
She contested their testimony that he drove on their orders to Botswana to collect weapons which were later booby-trapped and allowed to fall into the hands of ANC cadres.
She said he had never been away from home for long enough to have gone to Botswana and she never saw him drive a car.
Mrs Maake said she was opposed to amnesty being granted. The courts should decide the applicants' fate, she said.
