A lawyer for an Irish nanny charged in the US with beating an infant who later died has won a request to preserve evidence in the case, including the baby’s travel records and a list of people who had access to her.

Irish nanny Aisling McCarthy Brady is due back in court in the US today.

Investigators have spoken of the “unimaginable pain and suffering” that the parents of Rehma Sabir are enduring as they come to terms with the death of their baby daughter.

A blood-stained pillow, blanket and baby wipes were found in the bedroom of a one-year-old child who died after her Irish nanny allegedly assaulted her, according to court records.

Harrowing detail of the last few hours of Rehma Sabir’s life have emerged in a “statement of probable cause” presented at Aisling McCarthy Brady’s court appearance.

A priest has said there is no foundation to charges against the Irish nanny accused of assaulting a one-year-old baby, who later died.

An Irish nanny living in the US, who has been charged with violently assaulting a baby who later died, may yet face a murder charge, the district attorney’s office has said.
