I'm glad you mentioned it. I would be surprised if, upon hearing the news, a local priest did go to the site and say the prayers. I know mine would. Whether one did or not, the rest of us can offer a prayer for the repose of their souls.
Eternal Rest grant unto them, O Lord, and may perpetual light shine upon them. By the mercy of God may their souls and the souls of all the faithful departed rest in peace. Amen.
Amen!
