Two men arrested in connection with the murder of a former garda have been released without charge.
John Kerins was shot dead at his remote rural home in Cornaveagh, near Bailieborough, Co Cavan, last November.
Mr Kerins, who was in his late 40s, had been questioned over the disappearance of his neighbour Gerard Daly 18 months earlier.
He died from gunshot wounds to his upper body.
The arrested men were released from garda custody on Tuesday night.
