Johnston was a 21-year-old chemist and shop worker from Tonaghgorm, Legg, near Belleek, County Fermanagh.
Johnston and her fiancé were sitting in her father's car, outside her home, when members of the IRA murdered her by firing 27 bullets into Gillian,[3] killing her and wounding her fiancé.
[4] The IRA later claimed the murder was a mistake and that the intended target had been Johnston's brother, whom they had claimed was a member of the Ulster Defence Regiment (UDR).
There was unconfirmed speculation that this unit was also responsible for the Remembrance Day bombing in Enniskillen in November 1987.
I don't think I ever heard her say a bad word about anyone, people are just horrified."
