Molly Martens and her father Thomas Martens were indicted on Monday over the death of Limerick man Jason Corbett in America last summer.
The Davidson County Grand Jury confirmed that 31-year-old Molly Martens and her father, 65-year-old Thomas Michael Martens, have been charged with second-degree murder and voluntary manslaughter.
A statement released on behalf of the family to newspapers in North Carolina said the pair would be exonerated once the events were presented before a trial and that both would plead not guilty.
Mike Earnest is Tom Marten's brother-in-law, and the uncle of Molly Marterns.
“I’ve known Tom for 44 years and Molly since she was born, there are no finer people you would care to meet.
"The actions of self-defence that Tom and Molly took on 2 August were completely necessary and justified,” the statement said.
The family added that they were “extremely disappointed” with the grand jury’s action, but said that they had “complete faith” in the justice system.
“Since the 911 call was made that morning, both have co-operated fully with the investigation and made themselves available every step of the way.
"Once the events of 2 August are presented, they will be exonerated,” the statement added.
Mr Corbett, who was originally from Janesboro in Limerick City, died after an alleged domestic dispute at his home in the US state of North Carolina last August.
The 39-year-old’s body was discovered at his home in Panther Creek Court, close to the town of Wallburg, in the early hours of the morning on 2 August.
Mr Corbett is understood to have died as a result of serious head injuries.
Speaking to Ireland Live, Assistant District Attorney at Davidson County Greg Brown said that both Molly and Thomas Martens are out of state in Tennessee.
Mr Brown explained that they have been asked to present themselves to the authorities, and are expected to appear in court to be charged with second-degree murder and voluntary manslaughter.
A trial is expected to take place this year.
At the time of his death, Mr Corbett had been living in the US for four years with his children from his first marriage, Jack, 10, and Sarah, who is eight.
The death of Mr Corbett resulted in a custody battle between Ms Martens, the children’s stepmother, and Mr Corbett's sister and brother-in-law.
At Davidson County Courthouse in North Carolina in August, Judge April Woods upheld a decision to grant guardianship of the children to Mr Corbett’s sister Tracey Lynch and her husband David.
Following the recent developments, Tracey and David Lynch have released a statement on Facebook.
