Father-of-two married new love after death of first wife
Jason Corbett, a businessman originally from Limerick city, was found with fatal head injuries at his home in North Carolina last August.
He was allegedly battered to death with a baseball bat in the house he shared with his second wife, Molly Martens.
The 39-year-old's first wife Mags, the mother of his two children, Jack (11) and Sarah (9), died after suffering an asthma attack in 2006.
Her widower later set up the Mags Corbett Trust, which raised tens of thousands of euro for the Irish Asthma Society.
He moved to the USA in 2011 and later married Ms Martens, who had been the children's nanny.
According to a police incident report, deputies responded to the Corbetts' residence just after 3am on August 2, 2015.
Deputy C.S. Dagenhardt wrote in a report that while Deputy D. Dillard was in route to an assault at a residence in Panther Creek Court, the Davidson County 911 Center advised a 999 caller had been in an argument with his son-in-law and struck him with a baseball bat.
The two policemen arrived at the address and found Mr Corbett inside the home with head injuries.
Ms Martens and her father Thomas Michael Martens were in the house at the time.
Jason's two young children were embroiled in an intense custody battle following his death.
His sister Tracey Lynch - who flew to the US - now has the children in her care in Limerick.
Ms Martens also lost a subsequent appeal against the court ruling to allow the children return to Ireland with their aunt.
Since the custody battle, Ms Martens has been regularly posting messages and photographs of the children on Facebook.
Ms Martens made an attempt to contact her stepchildren on New Year's Day, posting a picture of herself and Sarah along with her phone number, email address, and a brief message: "Jack and Sarah, New Years two years ago... There are not words for how much I miss you."
As recently as last night, Ms Martens posted a statement claiming "the truth doesn't matter".
Jason's sister, Tracey, said their grief was further compounded by the actions of Ms Martens.
In a recent interview, she said both children are doing well despite the death of their father.
"It's a really positive environment in our house. It's happy most of the time, but we still miss Jason terribly, so obviously that shadow is always there," she said.
