A former Rwandan officer on Monday was found guilty of genocide and crimes against humanity during the 1994 genocide and sentenced to life imprisonment by the International Criminal Tribunal for Rwanda in Arusha.

Ildephonse Hategekimana, a Lieutenant in Rwanda Armed Force and the former Commander of the Ngoma Camp, was found guilty “on three counts of genocide for killing of Tutsi at Ngoma Parish and at Maison Généralice,” the ICTR said.

He was also convicted for crimes against humanity for several murders and raping a woman. The three judges in the case acquitted him of one count of complicity in genocide.

The sentence was reached, the judges said, “after considering the gravity of each of the crimes for which the accused had been convicted as well as the aggravating and mitigating circumstances mentioned by the parties.”

Hategekimana was arrested in 2003 in Congo Brazzaville, and was transferred to the UN Detention Facility in Arusha.

His trial opened in March last year, where he was charged with collaborating with others in the preparation and execution of Tutsis and moderate Hutu politicians in 1994, and for overseeing a civilian massacre in Butare by the infamous Interahmawe militia. Some 40 witnesses were heard during his trial.

Last month, the ICTR convicted Rwandan businessman Gaspard Kanyarukiga to 30 years in jail for his role in an April 1994 church massacre that killed some 2,000 Tutsi refugees.
