New DNA testing has been used to solve two long-term missing people cases in Ireland.

Advancements in the technology have led to the identification of previously unidentified remains.

Testing by Forensic Science Ireland has identified the remains of 59-year-old Margaret Glennon from Baldoyle in North County Dublin and 18-year-old James Gallagher from Cabra in Co Dublin, reports RTÉ’s Prime Time.

The remains of Margaret Glennon were discovered near Swords in 2014, 19 years after she went missing.
