The results of the investigation into the murder of Archbishop Michael Courtney in Burundi last year have been presented to the Minster for Foreign Affairs, Mr Cowen.
Mr Cowen did not comment on the details of the investigation but last week a 20-year-old admitted to involvement in the killing.
Burundian Foreign Minister, Mr Therence Sinunguruza presented the results to Mr Cowen in Dublin today.
After the meeting, Minister Cowen announced the establishment of the Courtney Fellowship which will sponsor a Burundian student to pursue a Masters level course in governance or peace studies over one year for the next five years.
"The establishment of this fellowship is a fitting memorial to the late Archbishop Courtney. It will allow his work for peace to be built upon and leave behind a lasting legacy," Mr Cowen said.
During his visit, the Burundian Foreign Minister will also meet with the family of the late Archbishop and tell them of the Burundian government's decision to present a posthumous award to Archbishop Courtney.
The Burundian peace process was also discussed and Mr Cowen declared Ireland's and the EU's support for ongoing efforts.
Archbishop Courtney (58), from Nenagh in Co Tipperary, who was a key mediator in peace talks in Burundi, was travelling in a diplomatic car carrying the Vatican flag in late December when he was shot dead in an ambush.
Two other occupants of the vehicle, both Burundian and one a priest, were uninjured.
The archbishop was returning from the funeral of a priest in the Minago district of Burundi. He had been in the country for three years, and was due to leave for Cuba next month.
Speaking after today's meeting with Mr Therence Sinunguruza, Mr Cowen described the murder of Archbishop Courtney as "a truly tragic event for the people of Burundi, for his family, for the Holy See. "He [Archbishop Courtney] was a true disciple of peace," The Minister said.
