Investigations into yesterday's shooting at Bray Boxing Club in Wicklow are focusing on the gunman's getaway van.
Gardaí have named the man who died as 50-year-old Robert Messett, who is thought to have been an innocent bystander caught in the crossfire.
He was killed when a gunman opened fire just before 7am.
Detectives are investigating whether Katie Taylor's dad, Pete - one of the two others injured in the attack - was the intended target.

Gardai have issued a renewed appeal for information as part of their investigation.
It's believed the silver Volkswagen caddy with Northern Ireland reg plates used in the shooting travelled from Bray through Shankill and Cornelscourt before being abandoned on Pigeon House Road in the Ringsend area of Dublin just after 8am.
A man was seen leaving the van and cycling away.
Gardai are asking people who saw him or the van along that route between 7 and 8 o'clock this morning to contact them.
They're also appealing to people with dash cam footage along the route between 7am and 8am to come forward.
