LYRA McKee, who was fatally injured while covering street disturbances in Derry, is the second journalist to be killed in Northern Ireland since the outbreak of the Troubles - the third in Ireland.
The 29-year-old's murder, believed to be at the hands of dissident republicans, comes almost 18 years after the last killing of an investigative reporter.
Martin O'Hagan, who worked for the Sunday World, was shot and killed on September 28, 2001.
The 50-year-old was gunned down by the LVF as he walked with his wife back to their home in Lurgan, Co Armagh following an evening at a local pub.
Mr O'Hagan was the first working journalist to be killed in Northern Ireland since the outbreak of the Troubles in 1969.
Shortly before his death, Mr O'Hagan had expressed concern after being told that he was possibly under surveillance by members of the LVF.

The loyalist group had long harboured a grudge against him following the journalist's work exposing its campaign of nakedly sectarian assassinations against Catholics and large illegal drugs distribution network.
He was the first journalist to draw attention to the activities of the LVF founder Billy Wright, who lived only a few miles from Mr O'Hagan and had reportedly attempted to have Mr O'Hagan murdered in 1992.
That threat led Mr O'Hagan to temporarily move to the Sunday World office in Dublin, and then to Cork, although he returned to his family in Lurgan before the paramilitary ceasefires.
No-one has ever been charged with the murder.
Mr O'Hagan was killed 17 years after an attempt was made on the life of Sunday World northern editor, Jim Campbell, who was shot five times by two men who called at his Belfast home.
The well-know journalist, who had been investigating the UVF, was left dying on the floor in front of his wife and children following the attack in May 1984.
Taken to the Mater Hospital, his life was saved by a top surgical team, who had to revive him several times on the operating table.
Within six months, he was back at his desk, with an inoperable bullet still lodged in his spine.

Five years before Martin O'Hagan was killed, leading Irish crime journalist, Veronica Guerin was murdered.
The 37-year-old was shot six times by one of two men sitting on a motorbike, as she sat in her car on the Naas dual carriageway on June 26, 1996.
The journalist, who was married and had a son, had been investigating the criminal empire of a well-known drug lord for Ireland's Sunday Independent.
The shooting caused national outrage in Ireland.
Brian Meehan, from Crumlin, is serving a life sentence for her murder.
John Gilligan was acquitted of her murder.
