Investigations into the crash are now being headed by a senior investigating Garda.
Hundreds lined the streets of Clones county Monaghan last night, as the community comes to terms with the death of two local teenagers.
17-year-old Kiea McCann and 16-year-old Dlava Mohamed died when the car they were traveling in crashed on the N54 in between Clones and Smithborough, while they were on their way to the debs.
Investigations into the crash are now being headed by a senior investigating Garda.
The driver of the car - a man in his 60s - remains in a critical condition, an 18-year-old girl is in a critical but stable condition, while an 18-year-old boy is being treated for non-life threatening injuries.
Local Sinn Féin Councillor Pat Treanor says the community came together to mourn the loss of Kiea and Dlava last night.
