BELFAST, Northern Ireland, March 15 (UPI) -- The sisters of slain Belfast man Robert McCartney say they are not "stupid women" and reject Sinn Fein's warnings about manipulation.
They say the Irish Republican Army was behind their brother's killing after a brawl in a Belfast bar in January. One of them also accused Sinn Fein of being involved in a cover-up.
Sinn Fein Chief Negotiator Martin McGuinness warned the sisters Monday against being manipulated for political purposes.
But Catherine McCartney told the BBC: "We have to be very careful we're not being used by anybody ... we're not stupid women."
One of the sisters is threatening to stand against Sinn Fein in the May elections.
The IRA expelled three of its members and Sinn Fein, seven, over the killing. Last week the IRA revealed it had offered to shoot the men involved, an offer the McCartney family declined.
It later emerged two Sinn Fein candidates were in the bar on the night of the killing.
The sisters are to meet President George Bush Thursday, and will hand him a dossier on the case.
