Second letter about missing teen, Ciara Breen, sent to gardaí

Gardaí have received a second letter from an anonymous writer in relation to the 17-year investigation into the disappearance of teenager Ciara Breen.

Investigating officers revealed the receipt of the second letter on the RTÉ programme Crimecall on Monday night and appealed to the author to come forward.

The development follows the emergence of two witnesses — one last July and a second last month — who both gave valuable sightings of 17-year-old Ciara around the time she vanished from her home in Dundalk on February 13, 1997.
