New details show the case against Aisling McCarthy Brady, who is accused of fatally assaulting one-year-old Rehma Sabir, is full of "holes" according to Melinda Thompson, the lawyer who defended the 34-year-old Irish nanny at her arraignment on Friday.

Thompson, a former prosecutor herself says she is deeply convinced that Cavan native Aisling McCarthy Brady is innocent.

“I have gone through the police report line by line, over and over and over again. I can’t sleep, thinking about this. Things just don’t add up," said Thompson, according to the Boston Herald.

“This is a horribly sad case for everyone, the family as well as my client. She is devastated, totally devastated. (But) based upon my reading and what I’ve come to know about the timeline of events,” Thompson added, “I believe Aisling Brady never harmed that child.”

On the day that Brady allegedly unleashed a violent assault police say was equal to "a high impact motor vehicle collision" upon the little girl, she was also caring for a 7-month-old boy who had bed dropped off by his mother at the Sabir apartment in Cambridge, as part of a nanny sharing arrangement. The mother picked her son up that afternoon, before the 911 calls were made and Rehma was rushed to Children’s Hospital, where she would die two days later.

The next morning, the mother texted Brady, who had joined Rehma's parents in their vigil, saying she was sorry to learn of what happened and went on to ask Brady if she might be free to care for her son later that afternoon.

And two days before the alleged attack, Brady and her husband were invited by Rehma's family to join in celebrating the child's first birthday.

In the timeline which police have constructed, Brady had logged onto Facebook and was doing laundry at the Sabir home around the time she is alleged to have assaulted Rehma. The child's maternal grandmother was also in the apartment during this time and had joined the nanny in attempting to wake the child.

When asked about the traces of dried blood on wipes and bedding that was found several days after the child was taken to the hospital, Thompson said there was nothing found in any report to indicate Rehma was bleeding when she was taken to the hospital.

According to preliminary autopsy results, Rehma had bone fractures that were anywhere between 2 weeks to 2 months old, but for most of that time, the child was out of the country with her parents without Brady.

Prosecutors have said that, pending more autopsy test, the assault and battery charge on the nanny would soon be changed to murder.
