From Guardian yesterday.

Even before the Good Friday Agreement was signed in 1998, C Company had begun a clandestine terror campaign of "no claim, no blame", in which they tried to kill leading IRA figures in Belfast and anyone who crossed them within loyalism. In many incidents, they used booby-trap bombs to kill their targets. And they employed a military-trained bombmaker from Ballygowan, Co Down, to build more lethal and sophisticated devices.

Just two years before Nelson was murdered, an identical device was used to kill UDA man Glenn Greer on 25 October 1997. The 28-year-old died after a bomb containing about 1kg (2 lbs) of Powergel explosive, used in quarry blasting, exploded under his car near his Bangor home. Greer had previously confessed to C Company that he had been an RUC Special Branch informer.

The investigation into the Nelson murder two years later found that the same kind of under-car booby-trap that had been planted to kill Greer was used in her death.

The key link between the LVF in Mid Ulster, the bombmaker and Adair's UDA unit was a drug dealer from the Ballysillan area with links to Wright's new organisation.
