DNA samples from Philip Cairns' schoolbag not matched to Eamon Cooke

Gardaí say DNA samples taken from Philip Cairns' schoolbag do not match those from convicted paedophile Eamon Cooke.

Philip was 13 when he went missing in Dublin on October 23, 1986.

A woman came forward a few months ago to tell detectives investigating his case that she saw Philip in Cooke's pirate radio station that day.

Eamon Cooke died in June aged 79.

Gardaí say the investigation is ongoing and certain documents, diaries and tapes are still due to be forensically examined.
