Along with contemporaries such as his brother Herbie, Johnny Adair, Sam McCrory, "Fat" Jackie Thompson and Donald Hodgen, Millar was part of a skinhead gang that was involved in petty and violent crime in and around the lower Shankill in the early 1980s.
[3] Millar, Adair, Thompson and McCrory initially formed an active unit that drove around neighbouring republican areas looking for and occasionally attacking targets, notably Sinn Féin councillor Sean Keenan, whom the group injured in a shooting at his Andersonstown home in June 1990.
[6] According to David Lister and Hugh Jordan Millar committed his first murder on 31 July 1990 when he killed Catholic civilian John Judge at his home on the Falls Road.
The attack occurred as Judge was talking with a number of friends outside his house, where his son's fifth birthday party was taking place.
[12] Millar's appetite for wealth earned him the second nickname of "Boss Hogg" after the notoriously money-driven character from The Dukes of Hazzard.
[13] At this time Millar was living in the "Beirut" area of the lower Shankill, where close neighbours included Adair, Thompson, Hodgen and Winkie Dodds and from where C Company operated a dedicated drugs flat.
[19] Millar fled the Shankill with Gina Adair, John White and a number of C Company members under a police escort, catching a ferry to Cairnryan.
[23] This shooting, which claimed no casualties, was later revealed to be the handiwork of C Company member Alan McCullough, who hoped to use the attack to ingratiate himself with the mainstream UDA.
McClean, his family and supporters had been expelled from Belfast after a stand-off at the Westland Estate with the mainstream UDA the week before Millar gave the interview.
