On 24 August 1975, Catholic civilians Colm McCartney and Sean Farmer were stopped in their car at what is believed to have been another fake checkpoint at Altnamackin (near Newtownhamilton). They were driving home from a Gaelic football match in Dublin. The two men were found shot dead nearby. Earlier that night, three RUC officers in an unmarked car had been stopped at a checkpoint but allowed through. However, the officers suspected that the checkpoint was fake. After receiving radio confirmation that there were no authorised checkpoints in the area that night, they reported the incident and requested help from the British Army to investigate it, but no action was taken. RUC officer John Weir claims that UDR corporal and alleged UVF member Robert McConnell was involved in the attack.
