Killer Molly Martens, who is serving 20 to 25 years in jail for killing her Limerick husband Jason Corbett, has been accused of yet another breach of prison rules in the US.
Martens (36) faces the threat of fresh sanction for her fourth infraction of prison rules in just three years.
The former nanny was accused of possession of non-threat contraband in the North Carolina Correction Institute for Women (NCCIW) outside Raleigh.
Prison authorities cited her for the breach on July 7. No details on the nature of the contraband involved have been revealed by the North Carolina Department of Public Safety.
It was her fourth breach of prison rules since she was convicted, along with her former FBI agent father Tom Martens (69), of beating Mr Corbett (39) to death while he slept at their luxury home outside Winston Salem in North Carolina on August 2, 2015.
Both received 20-25 year jail terms for the second-degree murder of the Limerick father of two.
Her previous infractions involved disobeying an order from staff and possession of non-threat contraband on February 5, 2018, and unauthorised leave from a jail area on November 21, 2017.
Following her first infractions, Martens was transferred from the Southern Correctional Institute to NCCIW.
Molly Martens had previously been warned her sentence could be lengthened because of such repeated rules breaches.
Over recent times she has been participating in a special prison work programme in which selected inmates offer holiday advice via a special call centre to tourists visiting North Carolina.
Martens and her father are awaiting a North Carolina (NC) Supreme Court appeal against their 2017 convictions.
They lodged detailed submissions to the NC Supreme Court urging that a NC Court of Appeal ruling last February ordering them to be given a retrial should be upheld.
In their submission, which runs to almost 100 pages, they argued they did not receive a fair trial three years ago because key material they sought to introduce into evidence was not allowed by the trial judge.
They argued that this material was in support of their argument of self-defence and the state of mind that Tom Martens was in that night.
Their submission came one month after North Carolina prosecutors lodged their own legal argument urging the Supreme Court to uphold the original convictions.
Both father and daughter were convicted by unanimous jury verdict of battering Mr Corbett to death with a metal baseball bat and a brick as he slept.
Tom Martens is a retired FBI agent while his daughter, Molly, who married the Irish widower in June 2011, has suffered from a lengthy history of mental health problems.
Tom Martens and Molly Martens have both insisted they acted entirely in self-defence that night despite the fact neither had suffered so much as a scratch, cut or bruise at the scene.
In contrast, Mr Corbett's skull was so badly crushed that a pathologist subsequently could not accurately count the number of blows inflicted.
The trial heard evidence an attempt had been made to drug Mr Corbett, that he was attacked while asleep in bed and that he was beaten even after he was dead.
It was further stated the father and daughter then delayed ringing for paramedics just to ensure Mr Corbett was dead when they arrived.
