She had one previous conviction in 1993 for larceny.
Charlotte Mulhall was 21 years old when the killing took place.
Like her sister, she had a history of drug and alcohol abuse.
1996
He arrived in Ireland in December 1996, claiming to be a Somali called "Sheilila Salim" whose family had been killed in Mogadishu during the Somali Civil War.
Subsequent investigations revealed that he was in fact a Kenyan and that his family was still alive.
1999
The Department of Justice, Equality and Law Reform ordered that he be deported but he appealed and was granted Irish citizenship in March 1999 because he had become the father of an Irish-born child.
He had four previous convictions for offences including intoxication, threatening and abusive behaviour and assault.
2002
Their marriage broke down and Kathleen entered into a relationship with Farah Swaleh Noor in 2002.
Noor also allegedly abused Kathleen Mulhall.
Linda Mulhall was 30 years old at the time of the killing.
She was unemployed, had left school early and had four children.
The relationship with the father of her children broke up and she got into another relationship with an individual called Wayne Kinsella who subsequently abused them, in one case beating the children with an electrical flex.
The abuse was later investigated, and the children were taken into care by the social services, while Wayne Kinsella served a seven-year prison sentence for his cruelty to the children.
Linda Mulhall, meanwhile, had a history of alcohol abuse and suffered from an addiction to heroin.
2005
Linda and Charlotte Mulhall (also called the Scissor Sisters by the media) are sisters from Dublin, Ireland, who killed and dismembered their mother's boyfriend, Farah Swaleh Noor, in March 2005.
Noor was killed with a Stanley knife wielded by Charlotte and struck with a hammer by Linda following a confrontation with the sisters and their mother, Kathleen Mulhall.
His head and penis were sliced off and the rest of his corpse dismembered and dumped in the Royal Canal in Dublin where a piece of leg, still wearing a sock, was spotted floating near Croke Park 10 days later.
When Charlotte and Linda were charged with murder in December 2005, their father, John Mulhall, hanged himself in Phoenix Park.
Because of the method used in Noor's killing, the Mulhalls were dubbed the Scissor Sisters by the media.
Justice Paul Carney, presiding over the trial, said during sentencing that it was "the most grotesque killing that has occurred in my professional lifetime".
Charlotte Mulhall was given a mandatory life sentence and Linda Mulhall was given a 15-year sentence for manslaughter, with both being sent to Mountjoy Women's Prison in Dublin.
Noor's head and penis were never recovered, although Linda later admitted they had put the head in rubbish bins around Phoenix Park.
It was also thought that they carried the head by bus to Tallaght and buried it in a field, with Linda returning later to dig it up, carry it to another field using her son's schoolbag, smash it further with a hammer and bury it again.
Linda attracted further media attention when she slit her wrists and was sectioned (involuntarily hospitalised).
Charlotte also attracted media attention when a photograph of her holding a knife to a male prisoner's throat was published; that action resulted in an increased security presence in all Irish prisons and Charlotte was moved from Mountjoy to Limerick Prison.
She had a number of minor previous convictions for criminal damage and public order offences and was charged with criminal damage and sentenced under the Probation Act in October 2005.
She was also involved in prostitution.
During their trial, gardaí described the girls' upbringing as "troubled and tough".
Farah Swaleh Noor was 40 years old at the time of his death.
2006
The subsequent manhunt and the trial in October 2006 attracted intense media attention as the details of the crime slowly emerged.
The sisters and their mother were arrested but released until Linda confessed to involvement in the crime.
Kathleen Mulhall left the country to live in England.
2008
Kathleen Mulhall voluntarily returned to Ireland in February 2008 and faced several charges.
2009
She pleaded guilty to helping clean up the crime scene to conceal evidence and was sentenced to five years in prison in May 2009.
The case resulted in several books being written and has been examined in at least one television series.
It was said by the Irish Independent's legal affairs correspondent, Dearbhail McDonald, to have "fuelled fears of ritual killings in Ireland".
The Mulhalls were from Kilclare Gardens, a working class area in Tallaght, south Dublin.
Their parents John and Kathleen Mulhall raised a family of three boys and three girls.
Kathleen was originally Kathleen Ward before she got married and was from the Travelling community.
