Eugene Rwamucyo was convicted for aiding anti-Tutsi propaganda and attempting to destroy genocide evidence during the 1994 Rwandan genocide.

A Paris court on Wednesday sentenced a Rwandan former doctor to 27 years in prison for his role in the 1994 genocide in his home country.

Eugène Rwamucyo, 65, was found guilty of “complicity in genocide,” “complicity in crimes against humanity,” and “conspiracy” to prepare the ground for those crimes. He was acquitted of the charges of “genocide” and “crimes against humanity.”

Rwamucyo has denied any wrongdoing throughout the four-week trial. Three decades after the genocide, several witnesses travelled to Paris for the trial and provided graphic descriptions of the killings in the Butare region, where Rwamucyo was at the time.

This is the seventh trial related to the genocide in April 1994 that has come to court in Paris over the past decade. The massacres resulted in the deaths of more than 800,000 of Rwanda’s minority Tutsis and moderate Hutus who tried to protect them, killed by gangs of Hutu extremists backed by the army and police.

Angélique Uwamahoro, who was 13 at the time, said she came to court to “seek justice for my people, who died for who they were.” She testified that she saw Rwamucyo, who was her mother’s doctor, at the scene of a massacre in a convent where she and her family had sought refuge, noting that some of the dead included her family members.

After managing to escape, Uwamahoro said she encountered Rwamucyo again at a roadblock in Butare, where she heard him encouraging militiamen to kill Tutsi people. “He wanted to incite them to kill us so we don’t get out alive,” she said.

Other witnesses described mass graves and people burying bodies, including groups of prisoners who had been forced to do so. Some witnesses stated that wounded individuals were buried alive.

Rwamucyo was accused of spreading anti-Tutsi propaganda and supervising operations to bury victims in mass graves, according to the prosecution. He claimed his role in the mass burials was motivated solely by “hygiene-related” considerations and denied that survivors were buried alive.

Rwamucyo was arrested in a suburb north of Paris in 2010, where he was working as a doctor in a hospital at the time. French police arrested him while he was attending the funeral of Jean Bosco Baravagwiza, considered one of the masterminds of the genocide, who had been convicted by the International Criminal Tribunal for Rwanda in 2003.

In December of the previous year, another doctor, Sosthene Munyemana, was found guilty of genocide, crimes against humanity, and helping prepare for genocide, receiving a 24-year prison sentence. He has appealed his conviction.
