Shortly after the shooting, a Mitsubishi Lancer arrived and the would-be robbers made their getaway in it. No money had been stolen by them, but both vehicles used at the crime scene had been stolen.
The Gardaí had been armed with .38 Smith & Wesson revolvers and an Uzi, but the trial concluded that they had not had time to use them.
Bullet casings found at the scene were unique in Ireland to the IRA at the time.
Up to 40,000 people lined the streets of Limerick city for Jerry McCabe's funeral.
Initially, the killing was denounced by the leadership of Sinn Féin, but later the party lobbied for the early release of McCabe's killers under the terms of the Belfast Agreement.
Pearse McCauley from Strabane and three County Limerick men - Jeremiah Sheehy, Michael O’Neill and Kevin Walsh - were convicted by the non-jury Special Criminal Court of manslaughter. McCauley had escaped from Brixton Prison in 1991 while awaiting prosecution over an IRA campaign in England and had jumped bail in the Republic of Ireland two months before the shooting of Detective McCabe. O'Neill was released from prison on May 15, 2007 with Sheehy released on 4 February, 2008.
In 2000 McCabe's widow was presented with a Gold Scott Medal. The Scott Medal is the highest honour bestowed on a Garda by the Republic of Ireland who has shown exceptional courage and heroism risking their lives in their work as police officers.
