The family of missing schoolboy Philip Cairns has made a fresh appeal for the public's help in solving the case, twenty years after the 13 year old disappeared while walking to school in Ballyroan in south Dublin.

Philip's brother Eoin Cairns recalls family life spent with Philip.

He was my best friend being so close as we were in age.

Six days after Philip went missing a crucial piece of evidence, Philip’s schoolbag, was left in a local laneway. Detective Sergeant Tom Doyle says somebody with local knowledge left the bag in the laneway. He believes a number of people who were children at the time, may hold information that could help the investigation.

The schoolbag contains touch DNA and it is hoped in time forensic scientists will be able to create a profile for every person who came in contact with it. In the meantime detectives working on the case say anybody with information should come forward.
