The latest Dublin gangland feud victim, David Douglas, was a key figure in the 'finance' wing of the IRA, according to sources.
The 55-year-old father of one was approached by a lone male gunman and shot in the head and chest on Bridgefoot Street, in the Liberties area of Dublin's south inner city, shortly after 4pm on Friday.
Douglas was an 'active service unit' (ASU) volunteer with the Provisional IRA employed in 'fund raising' for the organisation from the early 1980s.
He was caught by gardai during a robbery of a post office in Tallaght in which he fired a rifle at a garda. He received a 12-year sentence for attempted murder.
He was closely associated with the Dublin IRA group which transformed from a 'Concerned Parents' movement, which protested against drug dealers in the inner city, to extorting money from drug dealers before moving full-time into the trade itself.
He was sentenced to five years' imprisonment for possession with intent to supply €562,000 worth of cocaine in April 2008.
It is believed Douglas was targeted as he walked to his wife Yumei's shop, Shoestown, after a family funeral earlier in the day. He was taken to St James's Hospital, and later pronounced dead.
Gardai are investigating whether the murder is linked to the bitter feud between the Kinahan cartel and Hutch mob.
Douglas was associated with the IRA unit in Dublin which worked for the then major heroin and cocaine supplier in the state, 'businessman' and property speculator, Jim Mansfield.
Mansfield, who died in 2014, was importing drugs through Weston Aerodrome in Lucan, which he bought from the profits of drugs money laundering and his considerable legitimate profits from property development.
The drugs were supplied by the Kinahan operation in Spain and Belgium. The Garda Special Branch had for years known of connections between Mansfield/Kinahan and the Provo smugglers, who adapted their arms importation routes to drugs importation in the 1990s.
Garda sources said senior IRA finance officer Joe Cahill, one of Gerry Adams' mentors, called at Mansfield's home on the last Friday of each month to collect protection money for the 'movement' - when the Provos claimed to be fighting the "scourge" of drugs in Dublin.
Hours after Douglas was shot, a man posted a message on the Shoestown shop's Facebook page calling him "drug dealing scum".
Ms Douglas took to Facebook to respond: "I don't know what to say. Are you ... another evil come to us?"
Last night, she shared a message for her late husband, writing: "Hiya Dathi, just want say something. I know you must be somewhere, maybe sat on the sofa, I try to see you there, and say good night, as normal".
