Rusagara had been battling cancer for an extended period. In July 2016, his wife, Christine Rusagara, also succumbed to cancer after receiving treatment in the United Kingdom.

In 2016, Rusagara was convicted of spreading false information and inciting public insurrection against the government, as well as action that sought to discredit the state. He was also found guilty of illegal possession of firearms.

After appealing his original sentence, Rusagara was sentenced to 15 years in prison by the Court of Appeals in 2019, reducing the 20-year sentence handed down to him by the Military High Court in 2016.

Throughout his career, Rusagara held several key positions, including serving as Rwanda’s military attaché in the United Kingdom, Permanent Secretary of the Ministry of Defence, President of the Military High Court, and Commander of the Nyakinama Military Academy.
