The 29-year-old writer and campaigner from Belfast had only recently moved to Derry when she was killed.
She was standing near a police 4×4 vehicle on the night of 18 April 2019 when a masked gunman fired towards officers and onlookers.
Regarded by many as a rising star in Northern Ireland media circles, she had written for many publications, including Buzzfeed, Private Eye, the Atlantic, and Mosaic Science.
She was named Sky News young journalist of the year in 2006 and Forbes Magazine named her as one of their 30 under 30 in media in Europe in 2016.
The Belfast woman had signed a two-book deal with the publisher Faber and Faber, with her forthcoming book The Lost Boys due out this year.
According to those who knew her best, the gay rights advocate was someone who “believed passionately in social and religious tolerance”.
Her death caused widespread revulsion in Northern Ireland.
