BOSTON (AP) — Investigators say a pillow, blanket and baby wipes stained with blood were found in the bedroom of the 1-year-old Massachusetts girl who died after she was allegedly assaulted by her Irish nanny.

Aisling (ASH'-ling) McCarthy Brady is being held on $500,000 bail near Boston after pleading not guilty Tuesday to an assault charge.

Authorities say she could be charged with murder after an autopsy is completed on Rehma Sabir, a Cambridge infant who was hospitalized with head injuries on Jan. 14 — her first birthday — and died two days later.

In court documents filed Tuesday, state police said they found a bloody blanket and pillow in a crib and blood-stained baby wipes discarded in a diaper pail.

Brady's lawyer says her client had no role in the baby's death.
