According to reports, Muvunyi had requested medical assistance in the United Kingdom (UK) but his plea went unanswered. He was arrested in the United Kingdom in 2010 and sentenced to 15 years in prison.

Muvunyi was discovered dead in the shower by one of his housemates on June 10. He had been residing in a safe house in Arusha, Tanzania, since his release in 2012, and he relocated to Niger in 2021.

Witnesses testified that Muvunyi played a role in inciting ethnic tensions during the genocide through inflammatory language and metaphorical calls to violence.

It is said that his metaphorical call worsened the situation, as Hutu men married to Tutsi women were encouraged to surrender them to be killed.

His convictions and sentence were initially overturned on appeal, leading to a retrial where he was found guilty of one charge of direct and public incitement to commit genocide.

The early release of the convicted perpetrator had sparked protests.
