The idea came from a garda serving in Co Cork who was born in the same village of Ballylongford.
The Garda Representative Association (GRA) is paying for the plaque.
Det Garda McCabe was shot dead as an IRA gang carried out a post office raid in the village of Adare, Co Limerick, on June 7, 1996.
Garda Omar Fitzell, a traffic corps officer based in Fermoy, said himself and his father, Paddy, decided it was time to ensure Det Garda McCabe is remembered in Ballylongford.
“The new owners of the McCabe house kindly gave permission for the plaque to be erected on it and we have received great assistance from Ballylongford Tidy Towns, local gardaí, Kerry County Council, and St Paul’s Garda Credit Union in Cork,” said Garda Fitzell.
“Up until now, there was no memorial marking that Jerry hailed from Ballylongford.”
Det Garda McCabe’s widow, Anne, described it “as a wonderful gesture from the GRA”. She said she will attend the ceremony, which will take place at 2pm on June 12, along with two of her sons, who are serving members of the force.
John McCabe is a sergeant in Shannon and his brother, Ross, is a garda based in Gurranabraher, Cork.
Anne’s other children, Stacy, Ian, and Mark will also attend.
A Garda ceremonial unit will march from the carpark to Bridge St where the plaque will be unveiled after brief speeches from the McCabe family, senior gardaí, and locals.
“Once unveiled everyone is invited back to the parish hall for some light refreshments. There may be road closures depending on the amount of people who are present. Both serving and retired gardaí are expected from Limerick, Kerry, and Cork,” said Garda Fitzell.
“Jerry gave his life in the service of the people of Ireland and we owe it to his memory to ensure the unveiling is adequately supported and a show of force that killing of a member of An Garda Síochána is absolutely unacceptable and will not be forgotten.”
