Three people died in the collision on Wednesday night, while another is being treated in hospital.
A Laois woman is among those who were killed in a crash in Carlow on Wednesday night.
Katie Graham, from Arles, Daryl Culbert and Michael Kelly died in the collision on the N80 at Leagh, when the car hit a tree and burst into flames.
Another passenger, a man in his 20's, has now been transferred to a hospital in Dublin.
His condition is serious but not life threatening.
Gardaí have described the scene as "horrific".
Speaking outside Carlow Garda Station, Superintendent Anthony Farrell made this appeal:
Carlow Kilkenny TD John McGuinness is expressing his condolences to their families after the tragic crash:
There's a dark shadow over Laois, Carlow and Wicklow following the collision.
They're the words of Bishop of Kildare and Leighlin, Denis Nulty.
Bishop Nulty says the crash brings him back to another fatal collision in the county nine years ago:
The road on which three people were killed in a crash in Carlow has a "history of fatalities," according to a lecturer in SETU.
Pauline Flanagan, who is friends with Mr. Kelly's mother, says she feels let down by Gardaí:
