The Tandragee killings take place in the early hours of Saturday, February 19, 2000, on an isolated country road outside Tandragee, County Armagh, Northern Ireland. Two young Protestant men, Andrew Robb and David McIlwaine, are beaten and repeatedly stabbed to death in what is part of a Loyalist feud between the Ulster Volunteer Force (UVF) and their rivals, the breakaway Loyalist Volunteer Force (LVF). The men are not members of any loyalist paramilitary organisation. It later emerges in court hearings that Robb had made disparaging remarks about the killing of UVF Mid-Ulster Brigade leader Richard Jameson by an LVF gunman the previous month. This had angered the killers, themselves members of the Mid-Ulster UVF, and in retaliation they lure the two men to the remote lane on the outskirts of town, where they kill and mutilate them. The UVF’s Brigade Staff (Belfast leadership) does not sanction the killings.

The origins of the lethal 2000–01 loyalist feud which erupts between the UVF and the LVF begins when a brawl breaks out in the Portadown F.C. Society Club on December 27, 1999. The leader of the UVF Mid-Ulster Brigade, Richard Jameson, is jostled and insulted by members of the LVF who are holding a celebration at the club to commemorate the second anniversary of the shooting death of their former leader and founder, Billy Wright, inside the Maze Prison by the Irish National Liberation Army (INLA).

Shortly after Jameson leaves the club, he returns with a number of UVF men armed with baseball bats and pickaxe handles. A violent altercation breaks out in which 12 people are seriously injured including three LVF prisoners out on Christmas parole. The LVF decides to retaliate and sends a gunman to assassinate Jameson in the driveway outside his home on January 10, 2000. The UVF’s Brigade Staff in Belfast immediately convenes a “war council” at “the Eagle,” their headquarters over a chip shop on the Shankill Road, where they discuss plans to avenge Jameson’s killing. The LVF’s leader, Mark “Swinger” Fulton, who is imprisoned at the time, claims to no avail that his organisation is not involved in the shooting.

At 1:30 a.m. on Saturday, February 19, 2000, Protestant acquaintances, Andrew Robb, a 19-year-old unmarried father, and David McIlwaine, an 18-year-old graphic design student at Lurgan Tech, both of Portadown, leave “The Spot” nightclub in Tandragee together with three others after spending Friday night out. The club is managed by Willie Frazer, well known as a loyalist victims’ advocate and political activist, who has since suggested that the killings were linked to a threat posed to him by the UVF. Billy Wright had reportedly frequented the nightclub before his imprisonment and death.

The group of three men and two women attempt to enter a taxi, but regulations stipulate that no more than four passengers can travel together. Robb and McIlwaine get out of the vehicle and head in search of a house party. The pair knocks on the door of a house in Sinton Park belonging to Mid-Ulster UVF member Stephen Leslie Brown, 19, also known as “Stephen Leslie Revels.” They are invited inside where other UVF members Noel Dillon and Mark Burcombe are also present. Alcoholic beverages are consumed at the party.

The atmosphere inside the house suddenly turns ugly when Dillon asks the teenagers how they feel about the LVF killing of UVF Mid-Ulster brigadier Richard Jameson. McIlwaine remains silent, however Robb replies, “So fucking what, it’s got fuck all to do with me,” to which Dillon takes exception. When he informs Robb that Jameson had been his good friend, Robb makes further disparaging comments which also anger Brown. Brown, out of earshot of the teenagers, decides to assault Robb in retaliation, saying he will “punch the head off Andrew.” Neither Robb nor McIlwaine has been a member of any loyalist paramilitary organisation, although Robb has tenuous links to the LVF having been an associate of Billy Wright and even photographed in 1996 at a march led by Wright. Writers Henry McDonald and Ian S. Wood allege that, unknown to the teenagers, a UVF unit had gone to “The Spot” to seek out two known LVF individuals rumoured to have been involved in Jameson’s killing; however, they had already left the nightclub by the time the UVF arrived. The UVF men encounter Robb and McIlwaine instead and target them as LVF members implicated in Jameson’s death.

Under the pretense of another party elsewhere, Brown lures Robb and McIlwaine into his car along with Dillon and Burcombe. Brown drives off toward Druminure Road where he stops the car at a gate leading to a field and orders the passengers to get out. Burcombe leads McIlwaine away from the vehicle. As they are walking downhill, Burcombe informs McIlwaine that the other two men are going to “give Andrew Robb a beating for slabbering about Richard Jameson. Don’t worry about it, it’s nothing to do with you.” Brown and Dillon proceed to attack Robb with a series of savage kicks. He is then stabbed deeply in the abdomen and throat and dies instantly. He also sustains wounds and gashes to his face and head.

The two perpetrators return, both “walking with a swagger” to where McIlwaine waits downhill from the parked car with Burcombe. McIlwaine makes an attempt to run away but Brown, Dillon, and Burcombe catch up with him as he falls to the ground. Brown gives him a severe kicking, mostly in the head. Dillon produces a butcher’s knife and cuts McIlwaine’s throat while Brown shouts encouragement and Burcombe overlooks the scene from about five feet away. Brown and Dillon leave McIlwaine still breathing on the ground. Once they are back inside the car, Brown proposes to drive the car over his head, but Dillon dissuades him. Brown halts the vehicle, takes the knife and walks back over to where McIlwaine is lying on the road making a “wheezing” sound. Brown stabs McIlwaine repeatedly in the face and chest. When he notices that McIlwaine appears to be looking up at him, Brown stabs him deeply in his left eye, the wound penetrating his brain, killing him. According to Burcombe’s later testimony, Brown appears “crazed” as he hands the knife back to Dillon and says he is “buzzing.” He subsequently goes on to recount stabbing McIlwaine in the eye. He threatens to cut Burcombe’s throat or kill a member of his family if he tells anyone what happened.

Several hours later, at 9:30 a.m., the mutilated bodies of Robb and McIlwaine are discovered lying in pools of blood on the roadside 100 metres apart from one another by a woman taking her children to dancing lessons. Because of the devastating stab wounds inflicted upon the teenagers, the Royal Ulster Constabulary (RUC) assumes that McIlwaine had received a shotgun blast to his face. Both of their throats are slashed so deeply that the teenagers are nearly decapitated. The RUC immediately sets up an inquiry into the killings. Postmortems reveal that Robb had sustained a severe cut to the neck and three penetrating wounds to the abdomen. There are no defence injuries. McIlwaine received a severe throat injury, seven penetrating wounds to the chest and penetrating wounds to the face and to the left eye. Both teenagers were intoxicated at the time of their deaths.

The killings deeply shock the community and are strongly condemned by local politicians. The young men’s funerals attract hundreds of mourners. They are buried in adjacent graves at Kernan Cemetery in Portadown.

After the attacks Adair brands the UVF “Protestant killers” and even produces a newssheet in which he lists McIlwaine and Robb as Protestant victims of the UVF along with the likes of the murdered Frankie Curry and regular targets Jackie Mahood, Kenny McClinton and Clifford Peeples. The UVF Brigade Staff in Belfast does not sanction the killings of Robb and McIlwaine. The LVF leadership, however, maintains that the blame for the killings lies with the UVF and threatens to strike back against carefully selected targets in the Belfast UVF.

The day after the homicides, a number of people are arrested in connection with the crime, including Noel Dillon. The arrests are not made under anti-terrorist legislation, and the suspects are all released unconditionally the same evening. On February 27, 2000, Stephen Brown is brought before the Armagh magistrate’s court after he is charged with both murders. The police tell the court they have plenty of forensic evidence connecting him to the homicides. Ten months later, Brown is released on bail after the court is told the prosecution has expressed doubts about their principal witness and the forensic evidence is not sufficient to secure a conviction. On February 6, 2001, the charges against Brown are unexpectedly dropped by the Director of Public Prosecutions. In April 2001, Mark Burcombe is arrested under the Prevention of Terrorism Acts in relation to his UVF activities but is released without charge.

David McIlwaine’s father, Paul, campaigns for nine years to obtain justice for his son. He enlists the aid of a nationalist human rights group and sets up his own online support group, “Justice for David McIlwaine.”

On November 2, 2005, the Tandragee double killing is reconstructed and featured on the BBC One programme Crimewatch in which a £10,000 award is offered. After viewing the programme, Mark Burcombe consults a clergyman and solicitor and subsequently presents himself to police outside Hillsborough Castle to give them information regarding the events which took place on February 19, 2000. He is interviewed about the killings over a period of four days and admits to having known both Robb and McIlwaine. He is arrested and charged with the murders along with Stephen Brown, who had also been arrested on November 7, 2005, in connection with the double killing. Noel Dillon had committed suicide in January of that same year. When Detective Chief Inspector Tim Hanley charges Brown with the murders, the latter pleads not guilty to each charge. In January 2008, shortly before his trial is due to start, Burcombe decides to turn “Queen’s evidence.” He formally agrees to admit to and give a full account of his own role in the murders and to give evidence against Stephen Brown. He signs an Agreement under the Serious Organised Crime and Police Act 2005 to receive a reduced sentence in return for giving evidence against his co-defendant.

Burcombe pleads guilty to the offence of conspiracy to cause grievous bodily harm to Andrew Robb and is sentenced to 28 months’ imprisonment with two months consecutive for an unrelated suspended sentence. The Robb and McIlwaine families are outraged and disappointed at the leniency shown to Burcombe. Sinn Féin president Gerry Adams asks Patricia Scotland, Baroness Scotland of Asthal, the Attorney General for Northern Ireland, to review the case and consider an appeal to impose a heavier sentence, writing that “all records before the courts on this crime verify it was a barbaric act.” Adams also goes on to affirm that he shares the McIlwaine family’s belief that a state agent was involved in the homicides and was being protected. Lady Scotland, however, backs the plea bargain deal.

Stephen Brown is found guilty of the murders on March 3, 2009. The trial, which commences on November 25, 2008, is held at the Belfast Crown Court without a jury. The prosecution relies upon three pieces of evidence to prove Brown’s culpability. These are the testimony of Mark Burcombe, the forensic material found by the RUC at the crime scene, and the hearsay evidence of Brown’s former girlfriend who claims he had admitted to her that he had killed McIlwaine. Burcombe declares that McIlwaine was murdered because he had witnessed Robb’s killing.

One month later, April 3, Brown is sentenced to 35 years in prison for each count of murder. The trial judge, who had passed sentence on Brown, declares that the murders are “among the most gruesome of the past 40 years.” He goes on to add, “they represent unbridled mindless violence and a total disregard for the value and dignity of human life.” Brown makes an unsuccessful appeal to have his murder conviction overturned on May 24, 2011.
