A blood-stained pillow, blanket, and a bucket of bloody baby wipes were found in the room of a baby, Rehma Sabir, who died after suffering traumatic head injuries, SkyNews reports.
The baby's nanny, Aisling McCarthy Brady, has been charged with assaulting the baby so violently that she cause head trauma, brain damage, and multiple bone fractures.
Court documents describe how the tragic case in Quincy, Mass., unfolded. On Jan. 14, a neighbor "heard the infant crying for almost an hour before it changed to 'extreme crying,' the Associated Press reported.
The neighbor apparently "knocked on the front door of the apartment for about 90 seconds, timing the knocks between the baby's gasping so it would be heard by someone inside, but they were not answered," according to SkyNews. Then the crying "started to slow and settle down before stopping completely," local police added.
Brady had sole custody of the baby at the time she was injured, said a statement released on the District Attorney's website.
In a video released by SkyNews, a neighbor described the nanny as a violent, volatile person.
"I wouldn't leave her watching my dog for an hour," he said. "She was an angry, angry person. She would go off the hinges, from zero to sixty, in like two seconds."
Brady, an Irish citizen who has lived illegally in the United States since 2002, has pled not guilty to the charges of assault and battery on a child causing substantial bodily injury.
She is being held in custody and "she may be charged with murder, pending the outcome of a medical examination of her alleged victim," SkyNews reports.
