Stompie Seipei

In a 2017 documentary, former Soweto police officer Henk Heslinga alleged that former safety minister Sydney Mufamadi had instructed him to re-open the investigation into the death of Seipei, for the purpose of charging Winnie with murder. In the documentary, Heslinga claimed that Richardson admitted during an interview that Seipei discovered he was an informant, and that he killed the child to cover his tracks. However, Mufamadi denied the allegations in the documentary, stating that Helsinga's statements were false. The documentary had been described by in a review by Vanity Fair as "unabashedly one-sided" and "overwhelmingly defensive". Commentator Max du Preez, called the decision by television station eNCA to broadcast the documentary in the week prior to Madikizela-Mandela's funeral without context a "serious mistake", and he described it as making "outrageous claims", while former TRC commissioner Dumisa Ntsebeza questioned the motives of the documentary maker.

Appearing before the Truth and Reconciliation Commission (TRC) in 1997, she said allegations that she was involved in at least 18 human rights abuses including eight murders were "ridiculous" and said that her main accuser, former comrade Katiza Cebekhulu, was a former "mental patient" and his allegations against her were "hallucinations". Cebekhulu had, himself, before the 1991 trial, been tortured, and kidnapped to Zambia, where he was detained for almost three years, at the behest of the ANC, before moving to the UK. The Commission found that the abduction of Stompie Moeketsi had been carried out on Winnie Mandela's instructions, and that she had "initiated and participated in the assaults", had resisted efforts by the "Mandela Crisis Committee" to get the boys released, and had attempted to cover-up the death by claiming that Moeketsi had fled to Botswana. With regard to the actual murder of Seipei, the Commission found Mandela "negligent in that she failed to act responsibly in taking the necessary action required to avert his death".

In 1991, Winnie Mandela was convicted of kidnapping and being an accessory to assault, but her six-year jail sentence was reduced to a fine and a two-year suspended sentence on appeal. Mandela's role was later probed as part of the Truth and Reconciliation Commission hearings, in 1997.

James Seipei (1974–1 January 1989), also known as Stompie Moeketsi, or Stompie Sepei was a teenage United Democratic Front (UDF) activist from Parys in South Africa. He and three other boys were kidnapped on 29 December 1988 by members of Winnie Mandela's bodyguards, known as the Mandela United Football Club. Moeketsi was murdered on 1 January 1989, the only one of the boys to be killed.

In February 1989, Abu Asvat, a prominent Soweto doctor,, who had examined Seipei after his abduction, was shot dead at his medical practice. Winnie Mandela's alleged role in Asvat's killing was later probed as part of the TRC hearings, after Asvat's murderers as well as her associate, Katiza Cebekhulu implicated her in the murder of Asvat, as part of a cover-up of Seipei's death. The hearings were later adjourned amid claims that witnesses were being intimidated on Winnie Mandela's orders.

Moeketsi, together with Kenny Kgase, Pelo Mekgwe and Thabiso Mono, were kidnapped on 29 December 1988 from the Methodist manse in Orlando, Soweto, the home of Methodist minister, Paul Verryn. Moeketsi was accused of being a police informer. Screams were heard as Stompie Moeketsi was murdered, at the age of 14, by Jerry Richardson, member of Winnie Mandela's "Football Club". His body was recovered on waste ground near Winnie Mandela's house on 6 January 1989. His throat had been cut. Jerry Richardson, one of Winnie Mandela's bodyguards, was convicted of the murder. He stated that she had ordered him, with others, to abduct the four youths from Soweto, of whom Moeketsi was the youngest. The four were severely beaten.

Moeketsi joined the street uprising against Apartheid in April 1985 at age ten, and soon took on a leading role. He became the country's youngest political detainee when he spent his 12th birthday in jail without trial. At the age of 13 he was expelled from school.
