Garda sources said they are trying to trace the movements of the woman with links to the McCarthy Dundon gang who was seen near the Kilteragh estate where the 28-year-old was gunned down early on November 9 in a case of mistaken identity.
He was shot as he walked home to his house in Clonmore where he lived with his fiance, Jenna Barry, after watching the Ireland-Canada rugby match at another house in Kilteragh with friends.
While the woman is not suspected of being at the scene when a gunman opened fire, a Garda said she may have been involved in the “logistical” lead-up to the shooting, passing on information about movements of people near Clonmore.
During door-to-door searches, gardaí have asked residents about sightings of a woman and a man. It also emerged yesterday that the intended target, his partner and their two young children were not at home at Clonmore when the gunmen opened fire.
The couple had been at a christening party at a hotel in the city and arrived back at their house in Clonmore at about 2am, about half an hour after the shooting.
The intended target has been seen driving in and out of Clonmore over the past few days in his top of the range Saab. The McCarthy-Dundons have put him on a death list because of his links to the rival Keane-Collopy gang.
Following a previous attempt on his life in August 2006, when up to 20 shots were fired at the known drugs importer, he installed bullet-proof glass at the house and other security measures including extra external lighting.
As revealed by the Irish Examiner, his partner acquired the house under the affordable housing scheme. She was approved by Limerick County Council despite a strict rule that people involved with or linked to antisocial behaviour cannot avail of the scheme.
Up to 50 gardaí, including detectives from the National Bureau of Criminal Investigation, are conducting the investigation under Supt Frank O’Brien. Extensive CCTV video footage is being trawled to track the movements of a car used by the suspect woman and a dark Renault car which was stolen last October in Ballysimon and found burned out in Rosbrien after the murder.
