Killers: Sisters

In October 2006, the murder trial of sisters Charlotte and Linda Mulhall unfolded in the central criminal court.

The two sisters sat impassively in the dock while the jury heard how they had brutally killed their mother's boyfriend in an alcohol and drug-fuelled frenzy. Newspaper headlines detailed how they had worked through the night to dispose of the body, going to the most extraordinary lengths to ensure that their victim could not be identified. Judge Carney described the murder as the most depraved case he had ever presided over.

Sisters tells the story of Charlotte and Linda Mulhall who murdered Farah Swaleh Noor, dismembered his body and disposed of it in the canal in Dublin. The pair subsequently became known as the "Scissors Sisters". While the story of the so-called "Scissor Sisters" began on a Sunday in March 2005, for Linda and Charlotte Mulhall the seeds of what happened were sown years earlier. The real story of the Mulhall sisters goes back to their childhood - and that is where our story begins. This documentary gives the full account of their background, the crime, the investigation and susequent trial of the sisters - and analyses the circumstances behind this most unique crime and what it says about modern-day Ireland.

Featuring exclusive interviews from forensic scientist Augustin Meir, whose findings were critical to solving the case, and psychologist Paul O'Mahony, the documentary also includes first-hand testimonies from those at the centre of the investigation and those who reported on the trial at the time. Direct excerpts from statements by the Mulhall sisters which were read into court feature throughout and form the basis of a series of dramatic reconstructions of the events of the night of the murder and the days that followed.

This landmark crime story belongs to RTÉ's occasional crime series "Killers."
