The sisters of stabbed Belfast man Robert McCartney today called for people to support the families of two other murdered men in their quests for justice.
The McCartney sisters, Catherine, Paula and Clare, attended a rally in Derry for the relations of Mark Robinson and Jimmy McGinley, despite being subjected to intimidation threats from republicans while delivering leaflets recently in Belfast's Short Strand area, where they live.
Around 200 people, including local politicians, turned out at the Civil Rights mural at the Free Derry Wall to highlight the cases of Mr McGinley and Mr Robinson, who were both allegedly killed by IRA members in the city over the past few years.
The crowd walked up through Guildhall Square via Butcher's Gate, the Diamond and Shipquay Street, before the family made speeches to the hundreds of supporters gathered.
The families urged the crowd to call upon the IRA to end any cover-ups around the killings of their loved-ones.
Eileen, the mother of the 23-year-old Jimmy McGinley - who was stabbed in the heart in October 2003 - said the demonstration showed that people would not stand for similar murders.
She said: "If what we're doing means that no other family will lose a wain like this then it's only a good thing. We want those responsible to know that we're not going to be treated like this any more."
She added: "We want proper justice."
The McCartney family have built a high-profile since the sisters and their supporters began campaigning for justice for their brother Robert, who was murdered by IRA members outside a Belfast bar on January 30.
Republicans have come under considerable political pressure after it emerged IRA members were involved in the murder of Mr McCartney and wounding of his friend Brendan Devine outside Magennis's Bar.
Detectives have encountered a wall of silence from those inside the bar.
The IRA expelled three members following the family's claim that a cover-up was taking place.
The McCartney family are due to hold a prayer vigil for the murdered father of two outside Magennis's Bar in Belfast tomorrow.
The McGinleys - in a similar case to the McCartneys' - claim they were subjected to IRA intimidation during the trial of his killer, Bart Fisher.
The outraged family launched a "Justice for Jimmy" campaign after 43-year-old Fisher was sentenced to three years in prison on a manslaughter charge last February.
Mr McGinley was stabbed in the heart outside Fisher's home at Sackville Court in Derry on October 2003.
The McGinleys have been demanding the IRA acknowledge that Fisher was a member and expel him from their ranks as well as lifting a threat made against the family before Fisher was sentenced.
The Robinson family have also been calling on the IRA to state publicly that anyone with information about the killing of Mark can go to the police without fear.
The 22-year-old was stabbed 11 times and beaten to death with scaffolding poles in an underpass in Derry in April 2001. IRA members were also blamed and no one has been charged with the murder.
Before Mr Robinson was killed, his mother and 15-year-old brother were allegedly threatened with a gun after IRA members forced their way into their home.
The family have said the identity of the killer has been openly thrown around in public through graffiti and people boasting.
