DUBLIN — A central Irish Republican Army figure in one of the outlawed group's most notorious killings has been shot to death in Belfast, residents and police said on Tuesday. No group claimed responsibility for shooting Gerard “Jock” Davison at short range outside his home in the Markets neighborhood of south-central Belfast. Davison was a Belfast IRA commander when he allegedly ordered IRA comrades in 2005 to attack a man, Robert McCartney. McCartney's widow and four sisters took their demands for justice all the way to the White House, and their embarrassing campaign helped spur the IRA to renounce violence and disarm later that year. Davison was arrested on suspicion of ordering the killing but not charged. Two others, including his uncle Terence Davison, were charged with McCartney's murder but acquitted in 2008. McCartney's sisters accused Gerard Davison of making a throat-slashing gesture to his IRA colleagues in the crowded pub shortly before McCartney, 33, was fatally stabbed outside the pub. IRA members confiscated the pub's surveillance video footage, cleaned up the forensic evidence and ordered pub-goers to tell police nothing or risk IRA retaliation, according to police and court testimony. IRA representatives met McCartney's widow and sisters and offered to have the IRA members responsible killed as punishment, an offer they rejected. The IRA and its allied Sinn Fein party later announced they had expelled three IRA members and eight Sinn Fein members over their alleged role in the assault on McCartney and the evidence cover-up. Davison's body lay in the street on Tuesday outside his home until police covered it with a sheet, then constructed a tent around the scene of the killing to preserve forensic evidence. Most IRA members are observing a 1997 cease-fire in support of Northern Ireland's peace process. But splinter groups continue to mount bombings and shootings and feuds within their fractured ranks can turn deadly. In Northern Ireland's last fatal shooting, a former Belfast commander of a faction called the Continuity IRA was killed in April 2014 in Catholic west Belfast. — AP
