Garda Chief Superintendent Pat Magee of the Louth/Meath division said that gardaí have been unable to identify a man seen running from the vicinity of her Ice House residence on the morning of the killing, despite earlier appeals to the public for information and the offering of a 10,000 reward by Crime Stoppers.
“There is information we have not got. There are people who know things who have not come forward yet,” he said yesterday.
The body of the popular mother-of-three was found with extensive stab wounds in her kitchen at 12.30pm on April 6, 2005.
The 43-year-old had suffered a brutal death. The State Pathologist said that she died from blood loss and haemorrhage.
She was found by her elderly mother Maureen McBride who was deeply affected by her death and she herself passed away just six months later on what would have been Irene’s birthday.
The investigation still has a team of detectives working on the case.
Dozens of statements were taken and, earlier this year, three people were arrested, two on suspicion of withholding information. However, they were released without charge.
Crime Stoppers offered a reward for information leading to the identification of the man seen running from the house and a prime suspect for murdering her, but it remains unclaimed.
The man was seen getting into a car parked nearby.
“It is unlikely he drove that car himself. The local people were most helpful. However, we believe that, in the criminal underworld, there are people with a lot of information,” said chief Supt Magee.
