The chief public prosecutor of Mauritius has insisted that the Michaela McAreavey murder case has not yet closed.
The 27-year-old daughter of Tyrone GAA manager Mickey Harte was killed in her hotel room at the Mauritian Legends resort in January 2011. She had married John McAreavey just 12 days previously.
Nobody has ever been convicted of her murder.
Mr. McAreavey last week announced plans to return to Mauritius in order to reignite the investigation in Michaela's death.
Speaking to the BBC, chief public prosecutor Satyajit Boolell said:
"We can't say this case is closed. We want to find out who the culprits are.
"Those who have taken the life of this young woman will have somehow to face justice.
"We are as determined, we are as concerned, as he (Mr. McAreavey) is.
"Any crime on our territory is a blot on our peaceful reputation."
Two hotel workers were initially charged with Michaela's murder but were subsequently acquitted.
