Gerard Steenson, an Irish republican paramilitary and a leader of the Irish People’s Liberation Organisation during the Troubles, is killed in an ambush in Ballymurphy, Belfast, on March 14, 1987.

Steenson, a Catholic and the son of Frank Steenson, is born in 1957 and raised in heavily republican West Belfast. He is nicknamed “Doctor Death” by the media and the Royal Ulster Constabulary (RUC) for the multiple assassinations he purportedly accomplishes according to The New York Times. However, Fortnight alleges that he got his nickname after he dressed up in a white coat to attack British soldiers guarding a patient at the Royal Victoria Hospital.

Steenson is widely associated with internecine violence between Irish republican groups. He joins the Official Irish Republican Army‘s Belfast Brigade in 1972 at the age of 14, becoming part of the Brigade’s C Company. Two years later, he leaves to join the Irish National Liberation Army (INLA) upon that paramilitary group’s formation, consequent to their split from the Official IRA. He becomes head of the INLA in Belfast.

Steenson first comes to notoriety as a teenager in 1975 for killing Billy McMillen, the Official IRA’s Belfast leader, during the feud between the INLA and the Official IRA. Jim Cusack, a journalist describes him as the “assassin-in-chief” of Hugh Torney.

During the 1981 Northern Ireland local elections, Steenson and Seán Mackin both lead efforts within the INLA to obstruct Irish Republican Socialist Party (IRSP) candidates which disrupts their votes, viewing the decision to run in the election as wasteful, believing that the allocated resources would be better spent on weapons. Following the election, Steenson later changes his mind with regards to elections, declaring that the party should have run more candidates.

In December 1981, Steenson, fearing that the Dublin INLA leadership will make a move on him following his efforts to set up a parallel organisation, plans an assassination attempt on the Dublin leader, Harry Flynn. Following a meeting of the Ard Comhairle on December 5, Flynn and others go out for drinks in the Flowing Tide pub at the corner of Sackville Place and Marlborough Street in Dublin. Shortly before 11 p.m., Steenson’s gunman enters the pub and fires shots at Flynn before his gun jams and he flees. Though seriously wounded, Flynn survives. After the botched assassination attempt, Steenson then unsuccessfully threatens Seán Flynn for his seat on Belfast City Council. Later, on January 25, 1982, a botched attempt is also made on Seán Flynn and Bernard Dorrian at a bar in the Short Strand area, provoking a feud where a unit from the Derry INLA comes to Belfast searching for Steenson. Failing to secure power, the attacks only demoralise the IRSP and INLA and begin a trend of internal feuds.

In 1985, Steenson is convicted of 67 terrorist offences (including six murders) after his former friend, Harry Kirkpatrick, testifies against him. Kirkpatrick and Steenson are rarely seen apart in public and are given the nicknames “Pinkie and Perky.”

In 1986, Steenson, Jimmy Brown, and Martin “Rook” O’Prey form the Irish People’s Liberation Organisation (IPLO), consisting of disaffected and expelled INLA members, with the express intention of wiping out the INLA and IRSP and replacing them with their own organisation. He argues in letters, written while he is in prison in the early 1980s, that the INLA has become militarily “inefficient” and that the IRSP leadership has become “ineffective” and requires “realignment.”

Steenson is involved in the Rosnaree Hotel shooting on January 20, 1987, where a meeting between the leadership of the INLA and IPLO is to take place to end hostilities. However, IPLO members ambush the four INLA members at the hotel, killing Thomas “Ta” Power and John “Jap” O’Reilly, while Hugh Torney and Peter Stewart manage to escape.

Steenson is viewed highly in the movement with Brown calling him a “committed and highly efficient military activist and a dedicated revolutionary.” However, he is described by Lord Justice Carswell as “a most dangerous and sinister terrorist. A ruthless and highly dedicated, resourceful and indefatigable planner of criminal exploits who did not hesitate to take a leading role in assassinations and other crimes.” Henry McDonald and Jack Holland write, “Both his friends and enemies spoke in a tone of awestruck at his paramilitary abilities.” Ken Wharton refers to him as a “notorious psychopath.” Sean O’Callaghan describes him as someone who “never took to orders.”

Terry George writes of Steenson that he “was extremely clever and even wittier than Billy McMillan. He had an angelic face and women adored him. He was also ruthless, cunning and fearless.”

On March 14, 1987, Steenson and Tony “Boot” McCarthy return to Ballymurphy after a night of drinking which is cut short by anger over the INLA GHQ faction’s show of force in the Divis Flats earlier in the day. After bringing their car to a stop on Springhill Avenue, they are killed in an ambush by an INLA active unit, with a member of the unit closing the security gate at the top of the street to trap the pair. An INLA spokesperson says Steenson was killed for being “actively involved in continuous and concerted efforts to undermine the authority of the … movement.” Jimmy Brown gives the graveside oration.

The IPLO later kills Emmanuel Gargan in the Hatfield Bar on the Lower Ormeau Road and Kevin Barry Duffy in Armagh, County Armagh, in retaliation for the killing of Steenson. The IPLO draws the ire of the Lower Ormeau community through the circumstances surrounding the killing of Gargan, with graffiti appearing in the area labeled “IPLOscum.”

On Halloween 1992, the Provisional Irish Republican Army carries out a large-scale operation (dubbed the “Night of Long Knives”) with the goal of neutralising the IPLO. Following the operation and execution of Jimmy Brown, both the Belfast Brigade and Army Council factions disband.
