Gardaí in Dublin are continuing to investigate the murder of Colm Owens last Friday.
Mr Owens, a 34-year-old father of one, was gunned down at work in Finglas.
A masked gunman walked into the Corn Store, an animal feed warehouse, on the Grove Industrial Estate at Dubber Lane, Finglas, and singled Mr Owens out, discharging a large number of shots from a handgun.
A getaway vehicle, a silver Audi A4, was driven by a second man and crashed into a number of other cars on Tolka Valley Road not far from the murder scene as it sped away. The men abandoned the 08 D-registered car on Carrigallen Road in Finglas South before fleeing on foot.
The killers, who gardaí believe panicked because patrol cars were pouring into the area, did not burn out the getaway car.
Gardaí are hopeful the vehicle will yield vital forensic evidence that could help solve the crime.
Mr Owens of Dunsoughly, Finglas, Dublin, had no convictions for serious crime but was a known associate of some of Dublin’s most notorious gangland figures.
He was a friend of Finglas gang leader Eamon Dunne, who was shot dead in a Dublin pub in April.
Mr Owens was also linked to one of two drug and armed robbery gangs based in Ballyfermot, Dublin, whose worsening feud claimed the lives of Kenneth and Paul Corbally in a gun attack two weeks ago.
