PSNI detectives have made a fresh appeal for information on the 20th anniversary of the Loughinisland massacre.
Football supporters were watching the Republic of Ireland play Italy in USA 1994 in the Heights Bar in the Co Down village when loyalist gunmen burst in and opened fire.
Six men were killed and five others were injured in the Ulster Volunteer Force attack.
Those who died were Barney Green, Adrian Rogan, Malcolm Jenkinson, Daniel McCreanor, Patrick O'Hare and Eamon Byrne.
To date, 16 people have been arrested, 51 searches have been conducted, 605 statements recorded and more than 2,500 actions raised as part of the investigation.
However, no one has ever been charged with the murders.
A renewed investigation was begun following a review of the case by the PSNI's Serious Crime Review Team.
Senior investigating officer PSNI Detective Chief Inspector Gareth Talbot said police remain committed to apprehending those responsible for the murders.
He said: "This was a sickening, indiscriminate and completely futile attack committed by terrorists who gave no thought to the innocent lives they shattered, then and now.
"On this 20th anniversary, with all its pain for families and survivors and perhaps reflection for those involved, I would ask anyone with information about the murders to come forward and speak to police."
He added: "The anniversary should bring into focus the fact that it is never too late to do the right thing, to come forward with any information about individuals or events."
