The most notorious incident to occur in Clonmany during the conflict happened on 10 May 1921, when two Royal Irish Constabulary constables - Alexander Clarke and Charles Murdock - were kidnapped and murdered by the IRA. Both men were stationed at the RIC Barracks in Clonmany. They went for a walk in the evening but were kidnapped near Straid. Clarke was shot and thrown into the sea, and his body washed up on the seashore near Binion the next day. Constable Murdock, who was from Dublin, reportedly survived the initial attack, escaped and sought refuge among residents of Binion. However, he was betrayed to the IRA who murdered him. His body has never been found. Local tradition suggests that he was buried in a bog near Binion hill. In June 1921, a military court was held in Clonmany to conduct a postmortem for PC Clarke. The court found that Clarke had died from a gunshot wounds to the heart, jaw and neck and that his firearm and ammunition was missing. At the time of his death, Clarke was 23 years old and unmarried.
