SOME of the killings to be investigated as part of the new probe into the activities of the agent known as Stakeknife and those in the intelligence services who directed him:
* Husband and wife Gerard (28) and Catherine (27) Mahon, who were shot dead after being taken away from their Twinbrook home in west Belfast in September 1985 and interrogated by the IRA who claimed they were informers. The Mahons were neighbours of estate agent Joe Fenton, who was also later killed by the IRA. When a number of IRA missions were compromised, Fenton is believed to have directed a member of the IRA's internal security unit to the Mahons
* Frank Hegarty. The body of the 45-year-old was discovered in Co Tyrone close to the border in May 1986. He had been shot dead and his eyes were taped shut. From the Shantallow area of Derry, the IRA alleged he was an informer who had revealed the location of an arms dump in Sligo to authorities
* Joseph Fenton. The 35-year-old, who worked as an estate agent, was shot in the head by the IRA in February 1989 after he was accused of working as an informer. It was alleged the father-of-four from west Belfast man was providing 'safe houses' for IRA planning meetings that were then bugged by the security forces
* Joseph Mulhern. The 22-year-old's body was discovered close to the Tyrone border 10 days after he disappeared from west Belfast in 1993. The IRA alleged he was working for RUC Special Branch
* Caroline Moreland. The 34-year-old mother-of-three was abducted from her home in the Beechmount area of west Belfast in July 1994. Her body was discovered dumped on the Fermanagh border 10 days after she disappeared. Her family had been warned by the IRA not to report her missing
* Margaret Perry (26) disappeared from her hone of Portadown in July 1991, with her body found in shallow grave at Mullaghmore, Co Donegal in June 1992. The IRA claimed she was killed by three men acting on behalf of British intelligence because she had discovered her former boyfriend Gregory Burns (34) was informing to the security forces. He, along with Johnny Dingham (32) and Adrian Starrs (29), were abducted, tortured and shot dead by the IRA
* Charlie McIlmurray (32), from Slemish Way in Andersonstown, was shot by the IRA in April 1987 following allegations that he had been working as an informer. His body was discovered in a van at Killeen in Co Armagh on the border
* Peter Valente (33), a father of four, was killed as an alleged informer in November 1980. Unusually, his body was dumped in the loyalist Highfield estate and a statement was released by Sinn Féin blaming the UDA. However, it is now thought that along with a number of other victims he was targeted by Stakeknife to protect his own cover as an agent after the IRA became suspicious
* Vincent Robinson (29) from Andersonstown in west Belfast was found dead in a rubbish chute in the Divis flats complex in June 1981. The IRA claimed he was an informer and had been outed by Peter Valente, something that his family denied. Again it is believed he was 'sacrificed' in order to protect Stakeknife
* Maurice Gilvarry (24) from Ardoyne in north Belfast was shot dead in January 1981 and his body dumped in south Armagh. Again it was alleged he was implicated by Peter Valente but it is now thought he was killed to protect the identity of Stakeknife
* Patrick Trainor (28). Married with three children, his body was found at waste ground near the Glen Road in west Belfast after he had been abducted by the IRA who alleged he was an informer, based on information they claimed came from Peter Valente. This was denied by his family and an RUC detective at a subsequent inquest
