Uwinkindi was a pastor at a Pentecostal church in the former Rural Kigali Prefecture (now Bugesera District) during the 1994 Genocide against the Tutsi.
He had appealed against the verdict of the High Court claiming that he was not given enough resources to hire private investigators for his defence, and that he was not given the defence lawyers he wanted.
The Court of Appeal has upheld the verdict after finding no reasonable evidences for his appeal.
Uwinkindi was convicted of murder as crime of genocide and extermination as crime against humanity.
The court said he committed the crimes between April and May in 1994.
According to the prosecution, between 100 and 150 Tutsi had sought refuge at Kayenzi Pentecostal church where Uwinkindi was a pastor.
Uwinkindi was arrested on June 30, 2010, in Kampala, Uganda. On July 2, 2010, he was transferred to the UN Detention Facility in Arusha.
In November 2010, the International Criminal Tribunal for Rwanda requested his referral to Rwanda. On June 29, 2011, ICTR Referral Chamber ruled in favour of extradition, marking the first time in the Tribunal’s history to do so.
Uwinkindi was born in former commune Rwamatamu in Kibuye Prefecture currently in Rutsiro district.
