South Africa is preparing to launch an official inquest into the mysterious death of the former director of Rwanda’s external intelligence agency, who was found dead in a luxury South African hotel four years ago. The body of Patrick Karegeya, 53, was discovered on December 31, 2014, in a room at the Michelangelo Towers Hotel in Sandton, an affluent suburb of Johannesburg. Karegeya was a leading member of the Rwandan Patriotic Army (RPA), the armed wing of the Rwandan Patriotic Front (RPF), which was founded in 1987 in Uganda by Rwandan Tutsi refugees. In 1994, the RPA, led by Paul Kagame, took control of Rwanda, thus putting an end to the genocide of up to a million Tutsis and moderate Hutus. Soon afterwards Karegeya was named Director General of External Intelligence in the RPA, which was renamed to Rwandan Defense Forces.

In 2004 however, after falling out with Kagame, who had become President of Rwanda in 2000, Karegeya was arrested, stripped of his rank of colonel, and served 18 months in prison for “insubordination and desertion”. He fled the country in 2007 and received political asylum in South Africa. The Rwandan government later claimed that Karegeya had been a double spy for South Africa. In 2010, Karegeya teamed up with General Faustin Kayumba Nyamwasa, who used to head the Rwandan Army, and had also escaped to South Africa after falling out with President Kagame. The two formed a new Rwandan opposition party in exile, called the Rwanda National Congress. The response from the government in Kigali was to try Karegeya and Nyamwasa in absentia in a military court. They were both sentenced to lengthy prison terms for “promoting ethnic divisions” in the country. In 2011, the Rwandan government issued international arrest warrants for the two former military men, but South Africa refused to extradite them.

When Karegeya was found dead in his hotel room, his neck was abnormally swollen and showed signs of strangulation; a rope and a bloodied towel were found tucked inside the hotel room’s safe, according to media reports. Nobody has ever been tried for Karegeya’s murder. On Wednesday, however, French news agency Agence France Presse (AFP) said that the government of South Africa will be launching a formal investigation into Karegeya’s killing in a matter of months. The news agency said it had spoken to “a South African court official […] who did not have permission to speak to the media”. The official told AFP that the probe is “not a trial, it’s a formal inquest”, which may eventually lead to a court case. The inquest will be officially launched on January 16, 2019, said the anonymous official.
