Christopher Divers, 20, from Penilee, died in April after a collision between the van he was travelling in and a pick-up truck near Fork Mountain, in North Carolina, in April.
His grieving parents Clare and Gary Divers say they have been left to piece together his final moments and they still do not know the cause or time of death.
As reported in yester-day's Evening Times, the family turned to Mr Salmond, asking him to put pressure on the Foreign and Common-wealth Officers to help.
A spokesman for the Scottish Government said the First Minister had written to the family to express his condolences.
Clare, 47, said: "I feel a bit more positive after getting the letter.
"He was concerned to hear that we had exper-ienced such difficulties getting information. We still need answers and I am hoping that, after Mr Salmond got involved, they will do something."
Christopher went to the US in March to train to be a golf green keeper. He was on his way back from a training day when tragedy struck.
The family's grief deepened when Christopher's fiancé Gemma Kelly, 20, learned after his death that she had suffered a miscarriage.
A Scottish Govern-ment spokesman said: "The First Minister conveyed his sincere condolences in a letter to the Divers family.
"We have contacted the Foreign and Commonwealth Office, who have assured us they are now in touch with the Divers and with the relevant authorities in the US to address the family's concerns, and to help ensure they get the information they are seeking about the death of their son."
