A pillow, blanket and baby wipes stained with blood were found inside the bedroom of a Massachusetts 1-year-old who was allegedly beaten to death by her Irish nanny, according to court documents filed by the police department.

Aisling McCarthy Brady, who is already incarcerated for assault, could be charged with murder for the death of Rehma Sabir, a Cambridge baby who was hospitalized with head trauma on her first birthday, Jan. 14, and passed away two days later, Fox News reported.

Court documents filed by prosecutors on Tuesday detail a disturbing scene inside the late infant's bedroom and also highlight a concerned neighbor hearing the child's cries abruptly stop.

The documents stated that the police searching the baby girl's room found a bloody blanket and pillow inside her crib, as well as bloodstained baby wipes that were thrown out in a diaper trashcan.

An upstairs neighbor told the police that on the day the baby was transported to the hospital, she heard the infant crying earlier for nearly an hour before she switched to "extreme crying."

The neighbor said that she attempted to knock on the front door of the apartment for roughly 90 seconds, even timing the knocks between the baby's cries in the hopes that someone else would also hear it. However, the knocks weren't answered and she reportedly heard the baby cry for an additional 10 minutes.

"It started to slow and settle down before stopping completely," the woman stated, according to the court documents.

The doctors who lexamined Sabir when she was admitted to Boston Children's Hospital found that the baby suffered severe brain injuries.

"Abusive head trauma includes injuries caused by violent shaking as well as impact to the head either by directly striking the head or causing the head to strike another object or surface," Dr. Alice Newton, the medical director of the hospital's Child Protective Team, stated about Sabir's diagnosis, according to court documents.

Authorities said Brady, 34, could be charged with murder after the Sabir's autopsy is done, though it is unknown as to when it will be completed.
