Mícheál Roarty (24) from Dunlewey, John Harley (24) from Falcarragh, Sean Harkin (22) from Falcarragh and Daniel Scott, from Gortahork, also in his 20s, all friends, were killed instantly when the car in which they had been travelling went off the road just before 9pm last night.
The four friends were all traveling in a Toyota Corolla, which crashed at Gleannhulaigh near Magheraroarty.
Emergency services attended the scene, but all four men were pronounced dead a short time later.
”It was a tragic scene,” Superintendent David Kelly said.
“Family members arrived and so there was good work done by all the emergency services in difficult conditions.”
The scene of the crash remains sealed off as Garda collision investigators begin the painstaking task of piecing together how the crash may have happened.
Tributes have been pouring in since the tragedy occurred.
The Mayor of Donegal, Falcarragh-based Councillor Seamus Ó Domhnaill, said: “It’s devastating for four young lives to be taken so quickly and so tragically.
“It will leave an awful dark, black cloud over West Donegal and one that won’t go away too easily.”
