Relatives of two of the six victims of the Glasgow bin lorry crash have broken their silence in a new documentary.
Adam Russell, the son of Jacqueline Morton, and Robyn and Lucy Ewing, the daughters of Gillian Ewing, spoke to BBC Scotland about the tragedy.
They also expressed concerns about the way the official investigation into the crash has been handled.
Harry Clarke, 58, was driving the council refuse truck when it veered out of control in the city centre three days before Christmas.
A fatal accident inquiry (FAI) at Glasgow Sheriff Court heard he lost consciousness at the wheel.
The inquiry, which adjourned on August 28, was also told he had a history of health issues and had not disclosed his medical background to his employers or the DVLA.
Mr Russell told the programme: “I just keep on thinking that one day I’m going to take my two girls up to see their granny Jacqui at the grave and they’re going to turn round and go ‘What did happen to granny Jacqui, daddy?’
“I’m just going to say ‘granny Jacqui lost her life because a man lied’ and that’s what I just keep on driving. That’s what drives me.”
Lucy Ewing, who was making her way up Queen Street with her mother when the accident happened, told BBC Scotland: “After we’d been told that mum had been killed, I had obviously lashed out a little bit and obviously said something about the driver having had a heart attack and the police instantly said, ‘I don’t know where you’ve heard that from, but that’s not what happened’.
“All they said was they weren’t able to tell us anything but they could confirm that the driver had not had a heart attack.”
The documentary also hears for the first time from two women who were injured and a former senior prosecutor who raises questions about the Crown’s investigation.
Mr Clarke resigned from his job at the city council last week hours before being due to attend a disciplinary meeting.
Erin McQuade, 18, and her grandparents Jack Sweeney, 68, and Lorraine Sweeney, 69, from Dumbarton, West Dunbartonshire, died from multiple injuries after being hit by the truck.
Stephenie Tait, 29, and Ms Morton, 51, both from Glasgow, and Ms Ewing, 52, from Edinburgh, were also killed as the lorry travelled out of control along Queen Street and towards George Square before crashing in to the side of the Millennium Hotel.
Sheriff John Beckett QC, who heard the FAI, said he would endeavour to issue his determination by January at the latest.
