Police have renewed their appeal for information about the death of a Coleraine teenager.
Ryan Quinn was killed when he was hit by a train January 2009.
He was assaulted in McLaughlin's Bar near Portrush and was then chased onto the nearby railway track.
Police and Ryan's parents have made a number of appeals since the murder and a file has been sent to the Public Prosecution Service in relation to two men aged 23 and 17.
A decision on whether to prosecute is expected soon. Police renewed their appeal on what would have been Ryan's 16th birthday.
Detective Chief Inspector Ian Harrison said despite a number of appeals they believe that people with information about what happened that night have yet to come forward.
"It's hard to understand how they could be so uncaring. I want to ask them again to look into their hearts and examine their consciences.
"A 14-year-old schoolboy lost his life. The family struggles to get through every day without Ryan and with the knowledge that people with information have not come forward."
DCI Harrison said they are uncertain about Ryan's movements between 2240 BST that night and just before 2300 BST when he was hit by the train.
"It's a short timeframe but it is very important.
"We know there was a sizeable crowd in the bar and that after some entertainment a considerable number of people went outside towards the smoking area," he said.
"We need all those people to come forward. A number of them have but some have not.
"I believe there are still individuals in the community who have significant information about what happened."
DCI Harrison said they are appealing for any information on the assault in the bar and the period between 2240-2300 BST.
"Anyone who does come forward will be dealt with sympathetically," he said.
Thursday would have been Ryan's 16th birthday and his family have planned a football match in his memory.
Friends and family will take part in a game at the Mountra Club in Coleraine on Saturday 12 June.
Ryan's family have also produced wristbands entitled 'Justice for Ryan'.
His mother, Lisa Kinnaird, said: "We just wanted to keep Ryan's memory alive in the community and for something positive to come out of his death.
"The money that we have collected for the wristbands has been used to buy strips for the Mountfern Day Centre football team."
