'˜All of a sudden the car just went under the water, it was desperate'
A man who was at the scene of Sunday night's tragedy in Buncrana has spoken of the terrible events he witnessed.
Francis Crawford spoke to the Derry Journal in this video.
The family were on a day trip to Buncrana, Co Donegal when their Audi Q7 car slid off a slip way into Lough Swilly on Sunday evening.
Sean McGrotty, 46, was with sons Mark, 12, and Evan, eight, in the sports utility-type vehicle along with his mother-in-law Ruth Daniels, 57, and her 15-year-old daughter Jodie Lee.
The only survivor was four-month-old baby girl Rionaghac-Ann.
Some people may find details of the interview upsetting.
