Galway Bay fm newsroom - An Oireachtas Committee has heard that it may not be possible to identify all those buried at the site of the former Tuam Mother and Baby Home.
Dr Niamh McCullagh - who led the forensic investigation team at Tuam, Bessborough and Sean Ross Abbey - says identification at Tuam will be particularly difficult.
She said due to the nature of the burials, many bones will have separated and mixed making individualisation, and subsequent identification, particularly difficult.
