Some people know more about the burial of children at the former Mother and Baby Home in Tuam than was provided to a Government investigation - that's according to the Minister for Children Katherine Zappone who has today published the fifth interim report from the Commission of Investigation of the Mother and Baby Homes.
The report also says there is little basis for the theory that babies born at the Tuam home were sold to America.
The report is highly critical of the Sisters of Bon Secours who ran the home and former members and officials of Galway County Council which owned it.
The 95-page report states that council members and staff must have known something about the manner of burial, as the local authority's sub-committees sometimes met on the site.
It says employees would have been in the grounds "quite frequently" as they carried out repairs to the building and "possibly" also maintained the grounds.
Meanwhile, the report found no physical or documentary evidence of systematic burials in the grounds of the Bessborough home and maternity hospital in Cork city.
But considers it "highly likely" that burials of some of the in excess of 900 babies and children who died while they were residents of the institution from the 1920s to the 1980s took place in the 200-acre campus.
The latest interim report of the commission throws light on serious concerns about burial practices at a number of former maternity institutions.
