please, Mrs Mandela, give us our son back. Even if he is dead, let Mrs Mandela give us the remains of our son, so that we must bury him decently." Sono and Shabalala's bodies were exhumed from pauper's graves in Soweto's Avalon Cemetery in 2013, by the National Prosecuting Authority's Missing People's Task Team, having been stabbed soon after their abductions. Seipei and Asvat killings On 29 December 1988, Jerry Richardson, who was coach of the Mandela United Football Club, abducted 14-year-old James Seipei (also known as Stompie Sepei) and three other youths from the home of Methodist minister Paul Verryn, with Richardson claiming that Madikizela-Mandela had the youths taken to her home because she suspected the minister was sexually abusing them (allegations that were baseless). The four were beaten to get them to admit to having had sex with the minister. Negotiations that lasted 10 days, by senior ANC and community leaders to get the kidnapped boys released by Madikizela-Mandela failed. Seipei was accused of being an informer, and his body later found in a field with stab wounds to the throat on 6 January 1989. In 1991, Mrs Mandela was acquitted of all but the kidnapping of Sepei. A key witness, Katiza Cebekhulu, who was going to testify that Madikizela-Mandela had killed Sepei, had been tortured and kidnapped to Zambia by her supporters prior to the trial, to prevent him testifying against her. Her six-year jail sentence was reduced to a fine on appeal. In 1992, she was accused of ordering the murder of Abu Baker Asvat, a family friend and prominent Soweto doctor, who had examined Seipei at Mandela's house, after Seipei had been abducted but before he had been killed. Mandela's role in the Asvat killing was later probed as part of the Truth and Reconciliation Commission hearings in 1997. Asvat's murderer testified that she paid the equivalent of $8,000 and supplied the firearm used in the killing, which took place on 27 January 1989. The hearings were later adjourned amid claims that witnesses were being intimidated on Madikizela-Mandela's orders. In a 2017 documentary about the life and activism of Madikizela-Mandela, 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 Moeketsi, as well as all other cases made against Madikizela-Mandela, for the purpose of charging Winnie with murder. According to Heslinga,
