Ruggiu's mother was a Belgian teacher, his father an Italian fireman. Until the age of 35 he lived at home and worked in Verviers, first as "a counsellor for young drug addicts and then as a teacher for mentally handicapped children". In 1992 he moved to the city ofLiège, commuting to Brussels to work in a social security office. In Liège he "befriended a Rwandan Hutu, was drawn into the Rwandan expatriate community and was soon seen in the company of Rwandan diplomats and officials of President Juvénal Habyarimana's party, the MRND". He began visiting Rwanda and moved there in 1993.
Participation in genocide
From January to July 1994, prior to and during the genocide, Ruggiu worked in Kigali, Rwanda, as a journalist and producer for Radio Télévision Libre des Mille Collines. Ruggiu had no experience in journalism and did not speak Kinyarwanda. RTLM was one of the chief sources of extremist Hutu propaganda, broadcasting twenty-four hoursa day and openly exhorting its audience to kill Tutsis and "disloyal" Hutus. Ruggiu personally wrote and broadcast much content of this nature, relentlessly egging on his listeners that the "graves were waiting to be filled". Ruggiu personally broadcast programs inciting Hutus to commit murder or serious attacks against Tutsi rebels, whom he called "cockroaches". He also encouraged persecution of these Tutsi, and moderate Hutu and Belgian citizens in the area. Airtime filled by Ruggiu accounted for approximately 8% of RTLM's broadcasts. Although some of his defenders have suggested that Ruggiu did not know exactly what was going on around him in Rwanda, this opinion is sharply disputed by Rwandan Genocide scholar Alison Des Forges: "It is beyond belief that Ruggiu did not know ... The tone of Mille Collines became more and more violent and witnesses say Ruggiu was living at the army barracks in Kigali and eating in the mess. He was hanging out with those that did the killing."
Capture, trial, and sentencing
After the genocide Ruggiu fled to refugee camps in Zaire and Tanzania and then to Kenya, where he converted to Islam and adopted the name Omar. He "joined a Somali Muslim community in Mombasa" and was "on the verge of fleeing to Iraq" when he was arrested by Kenyan police in 1997. On July 23, 1997, Ruggiu was arrested in Mombasa at the request of the prosecutor of the International Criminal Tribunal for Rwanda, and moved to the site of the tribunal in Arusha, Tanzania. Ruggiu was charged with "direct and public incitement to commit genocide" and "crimes against humanity ". During his three-year-long trial, Ruggiu expressed regret for his part in events, saying, "I admit that it was indeed a genocide and that unfortunately I took part in it." Ruggiu acknowledged his role in the genocide, admitting that he: He accepted responsibility for his actions, stating "certain people were killed in Rwanda in 1994 and that I was responsible and culpable". Ruggiu detailed the inner workings of Radio Télévision Libre des Mille Collines, stating the radio station was used to convey "the ideology and plans of Hutu extremists in Rwanda". On May 15, 2000, Ruggiu pleaded guilty to both charges of indictment, and was sentenced to twelve years in prison by the International Criminal Tribunal for Rwanda for incitement to commit genocide. He received a relatively short sentence, after agreeing to testify against three suspects who allegedly used the media, most notably RTLM, to fuel the genocide in Rwanda. Rwanda protested the sentence as inadequate. In February 2008, Ruggiu was flown to Italy to serve out the rest of his 12-year sentence in his country of citizenship. On 21 April 2009, Ruggiu was granted early release by the Italian authorities, a violation of the ICTR Statute.
