The children of Jason Corbett are at the centre of a custody hearing in North Carolina, later today.
The Limerick man died during an alleged domestic incident at his home in America last week.
His children from his first marriage - 10 year old Jack and 8 year old Sarah, are currently in the care of Mr Corbett's second wife, Molly Martens Corbett.
She is the main suspect in the case, as police say they are not looking for anybody outside the family home in relation to the Irish man's death.
Mr Corbett's brother-in-law David Lynch is due to ask the court for custody of the children.
