The mugshots of both Thomas and Molly Martens have been released following their transfers to separate prisons in North Carolina earlier this week.
The father and daughter were jailed in November after accepting a voluntary manslaughter plea deal for killing Limerick man Jason Corbett in 2015.
Mr Martens, 73, and Ms Martens, 40, were transferred to a maximum security prison in the United States on Tuesday night following two days of confusion around their release dates.
Ms Martens was admitted to the North Carolina Correctional Institution for Women in Raleigh, while Tom Martens was admitted to the Piedmont Correctional Institution in Salisbury.
Molly Marten's mugshot refers to her as Molly Corbett and her offender number is 1551729.
Thomas Marten's offender number is 1553797.
The pair were held in custody at Davidson County jail in Lexington, North Carolina, since November following their sentencing hearing.
The move to maximum security prison comes following a major miscalculation of their release dates from jail, which made international headlines and caused the family of the late Mr Corbett much distress.
This could have meant the pair would have only spent four weeks in jail after they were sentenced to a minimum of seven months and a maximum of 23 months.
"Human error" was blamed for the mix-up of their prison records which are accessible by members of the public online, according to a statement by the North Carolina Department of Corrections.
Molly Martens admitted killing her husband in August 2015 along with her father—the pair claimed self-defence. However, Judge Hall said they had “little or no injuries” after beating Mr Corbett to death and he added that this “did not make sense”.
The Martens both pleaded guilty to voluntary manslaughter and were returned to jail by Judge David Hall, where they have already served 44 months for the death of Mr Corbett. They were jailed for second-degree murder in 2017 but had their convictions overturned earlier this year and a re-trial was ordered.
