Gun fired in killing of cousins used in other hit
Gardai have linked last week's double murder to two previous shootings in Dublin earlier this year.
They are satisfied that one of two automatic pistols fired in the savage incident in Finglas had also been used in two non-fatal shootings on the northside of the capital.
Victims Glen Murphy (19) and Mark Noonan (23) were gunned down in the forecourt of a petrol station shortly before midnight on November 23.
The first cousins died in a hail of bullets after stopping at the station beside a Tesco supermarket at the Clearwater shopping centre.
The two gunmen and their accomplice, who was driving a black BMW getaway car, had been seen in the forecourt about five minutes before the victims arrived in an Avensis car.
This initially led gardai to believe that the two had been ambushed after being lured to their deaths at the station.
But officers said that the cousins did not behave as if they were meeting anybody when they arrived at the shop.
A clear motive for the shootings has not yet emerged. But gardai said last night they had no evidence at this stage to indicate any subversive involvement in the murders.
Last night, gardai renewed an appeal to anybody who was in the station forecourt or the Tesco supermarket on the night of Tuesday week last, or in the early hours of November 24, to contact them, either at Finglas station on 01 6667532, or the confidential line, 1800 666111.
