Thomas Martens and Molly Corbett1A Former FBI agent and his daughter have been sentenced to 20-25 years in prison for bludgeoning her Irish husband to death.

Thomas Martens, 67, and Molly Corbett, 33, both claimed self-defence in the 2 August 2015 killing of son-in-law two years ago
Martens and his daughter denied the charges of second degree murder in the death of Jason Corbett at Panther Creek outside Lexington in North Carolina in August 2 2015.
Mr Corbett, 39, died of blunt force trauma and was hit at least 10 times, according to the medical examiner.
A jury of nine women and three men unanimously found the two guilty of second-degree murder. She first met Mr Corbett in 2008 after travelling to his native Ireland to work as an au pair for his two children after his first wife died in 2006 from an asthma attack.
The Limerick native wed Molly Martens Corbett  in 2011 and moved to Winston-Salem, North Carolina.

Martens, who worked for the FBI for more than 30 years, had claimed he was defending his daughter after Mr Corbett choked her.
He told a 911 operator that night that he hit Mr Corbett “in the head with a baseball bat”, and that he heard him say: “I’m going to kill her”.
“He’s bleeding all over and I may have killed him,” Martens said during the call to emergency services.
The Davidson County jury was shown a metal baseball bat and a paving stone recovered at the scene, which prosecutors said were used to kill the Irishman.
Mr Corbett, a plant manager for a packaging firm, was beaten so badly that pieces of his skull fell off during a post-mortem examination, the trial heard.
The court also heard the father and daughter had delayed calling for an ambulance and pretended to carry out CPR after the attack in the master bedroom of the four-bedroom home.

Prosecutors said Molly Corbett did not appear to have suffered any injuries to indicate she had been assaulted, even as the  defense lawyers argued that investigators had failed to collect evidence that night showing otherwise.
Her attorneys said  Corbett said she had a mark on her neck, hair under her husband’s fingernails and blood on his feet, suggesting a struggle.
Martens-Corbett did not take the stand during the trial, but the judge allowed her to speak after the verdict.
“I did not murder my husband. My father did not murder my husband,” she said before sobbing.
She added that he was an abusive spouse and that “the incidents occurred as they did on a somewhat regular basis, the difference is that my father was there”.
“I’m really sorry to my mom, he should have just killed me,” she said.
There were emotional scenes in Courtroom C of the Davidson County courts complex as the verdict was delivered on the 16th day of the trial.
Members of the Martens and Corbett families – seated across the court aisle from each other, became emotional as the verdict was returned. Members of the Corbett family wept and embraced as the verdict was confirmed.
Jason Corbett’s family was represented by his brother, Wayne, his sister, Tracey, her husband David Lynch, among other family members and supporters.
For support Thomas Martens and his daughter Molly had his wife Sharon Martens, sons, Bobby and Connor, as well as Ms Martens-Corbett’s uncle, Michael Earnest.

Davidson County prosecutors had claimed Mr Corbett was fatally attacked because he planned to move back to Ireland with his children, Jack (10) and Sarah (8), but without his second wife.He had refused to sign adoption papers giving his US wife equal rights to the children.
His first wife, Margaret ‘Mags’ Fitzpatrick, had died of an asthma attack in 2006 when the children were both aged under two years.
Ms Martens Corbett was also the main beneficiary of a $600,000 life insurance policy on her husband.
Her father, Thomas Martens, admitted he disliked his Irish son-in-law and wanted his daughter to divorce him.
Mr Martens told the trial he could not specifically recall telling a US Department of Energy colleague: “That son-in-law – I hate him.”
Assistant District Attorney Greg Brown claimed that, having brutally bludgeoned Mr Corbett, his wife and father-in-law then deliberately delayed ringing 911 to allow Mr Martens, a counter-intelligence operative, to come up with a story for what had happened.

Prosecutors claimed Ms Martens Corbett first tried to dose her husband with the powerful sedative, Trazedone, in a homemade mint Mojito drink on August 1, 2015.

She had obtained the prescription for the medication just two days before.
Mr Corbett, who had been working in the garden of his Panther Creek home, had enjoyed about six or seven beers with a neighbour on his front lawn earlier that Saturday evening.
His parents-in-law, Thomas and Sharon Martens, had both arrived for an unexpected visit that evening.

The father and daughter claimed they killed Mr Corbett in self-defence after he attacked the Tennessee woman and tried to strangle her in the master bedroom of their home.
However, Assistant District Attorneys Greg Brown, Alan Martin and Ina Stanton claimed the evidence indicated Mr Corbett was first struck when he was in bed or beside the bed.
They claimed the father and daughter then subjected the Limerick businessman to “a horrific, heinous, brutal and cruel” assault using a metal bat and a brick.
Corbett fought for and lost custody of her two step-children after her husband’s death.
Guardianship was granted to Mr Corbett’s sister, Tracy Lynch, who testified in court on the prosecution’s behalf.
“Jason will be remembered for who he was, not for how he died,” Ms Lynch said after Wednesday’s verdict.
Several jurors wept at the verdict was returned after three hours and 20 minutes of deliberation.
Molly Martens Corbett wept and cried aloud when the unanimous guilty verdicts were returned by the jury of nine women and three men.
She had to be comforted by her lawyers.
