A Laois woman was among the three who died in the collision last week.
Gardaí are renewing their appeal for information on the car crash in Carlow which killed three young people.
The single vehicle collision occurred at half eleven on the N80 at Leagh on the Wexford Road last Wednesday night.
Laois' Katie Graham, Daryl Culbert and Michael Kelly all lost their lives in the incident.
A fourth person in the car was injured and remains in the Mater Hospital in Dublin.
Anyone who may have dash cam footage or saw something that night is being asked to contact Gardai.
