[2] McGeown was born in the Beechmount area of Belfast, Northern Ireland on 3 September 1956, and joined the IRA's youth wing Fianna Éireann in 1970.
[11] Following the deaths of five other prisoners, McGeown's family authorised medical intervention to save his life after he lapsed into a coma on 20 August, the 42nd day of his hunger strike.
[11][12] McGeown was released from prison in 1985, resuming his active role in the IRA's campaign and also working for Sinn Féin, the republican movement's political wing.
[13] At an early stage of the trial his solicitor Pat Finucane argued there was insufficient evidence against McGeown, and the charges were dropped in November 1988.
[15][16] Despite suffering from heart disease as a result of his participation in the hunger strike, McGeown was a member of Sinn Féin's Ard Chomhairle and active in its Prisoner of War Department, and in 1993 he was elected to Belfast City Council.
