The parents of a baby girl who died in Massachusetts while in the care of an Irish nanny are suing her.
Sameer Sabir and Nada Siddiqui are the parents of Rehma Sabir who died just after her first birthday in January 2013.
Cavan woman Aisling Brady McCarthy spent almost two-and-a-half years in prison charged with murder and awaiting trial before charges were dropped against her last summer.
She was freed from custody but placed under house arrest before returning to Ireland in September.
The Sabir family filed legal papers to the Middlesex County Superior Court yesterday.
In an interview with the Boston Globe, the couple said their main motivation for the law suit was to ensure that Ms Brady McCarthy did not "make money off their child's death, through such ventures as book deals or movie contracts".
Their lawyer Jonathon Friedmann told the newspaper that the couple said they would drop the lawsuit if Ms Brady McCarthy "signed an agreement not to profit from Rehma's death".
In filing the complaint to the court yesterday, Rehma's parents have requested a jury trial to decide the matter if an agreement cannot be reached in advance.
Ms Brady McCarthy had been accused of killing the one-year-old by shaking her.
The Office of the Massachusetts Medical Examiner carried out a review of the evidence in the case.
The Medical Examiner subsequently said she was no longer convinced that the bleeding on the baby's brain could only have been caused by abusive head trauma, but could in fact have been an accidental injury or an undiagnosed natural disease.
As a result the District Attorney said she could no longer meet the burden of proof required for murder and dropped the charges.
However upon her release, Ms Brady McCarthy was deported as she had been an illegal, or undocumented, immigrant in the US for more than ten years.
At the time, her lawyer said her client wanted to get home to Ireland as soon as possible, saying her life had been ruined by what had happened.
