Corbett's second wife tried to adopt children
A second day of hearings will take place in North Carolina today as the family of Irishman Jason Corbett, who was killed in the US, battle for custody of his two children.
The Corbett family are hopeful that they will be able to return with Mr Corbett's two children Jack (10) and Sarah (8) later this week.
The children's mother, Mags, died in 2006 after suffering an asthma attack.
Mr Corbett's older brother John said that Jason's second wife, Molly Martens Corbett, had tried to adopt the children but that Jason was reluctant. He said this issue had caused friction and arguments between the pair.
"Molly was trying to adopt the kids for the past two months but Jason always seemed reluctant and they did have rows about it," he said.
"She was trying to persuade Jason to adopt the kids so that they could get US citizenship," he added.
"You would think that would be a natural progression, but Jason did not want that.
"When my brother Wayne was in North Carolina a week before Jason died, she said that she would like to adopt the kids. Jason didn't even respond."
It emerged over the weekend that the 911 call reporting the fatal domestic incident at Mr Corbett's US home was made by a man saying that he had struck his son-in law on the head with a baseball bat.
Mr Corbett died after suffering serious head injuries.
His wife Molly was believed to have been the main suspect but police in the US have confirmed that her father Thomas Martens (65), a retired FBI agent, is also a person of interest.
