Detective Inspector Michael Winters is the Senior Investigating Officer leading enquiries into Caoimhin’s death.

Detective Inspector Winters said: “It is three years since Caoimhin died, and our investigation into what happened continues. We believe Caoimhin was not travelling alone in the red Mazda, that other people were with him.

"On that basis, we believe there are people within the community who can help us with our investigation. I want to make a direct appeal to anyone who has information to do the right thing and tell us what you know."
