I lived in Killingly for some years. You probably are thinking of the wrong Dunkin. The article states they live near the Troop D barracks, so it's not the Dunkins in Killingly Commons, and the Dunkin closest to the troop D barracks is not on a difficult road at all. It's quite possible the children did not have to cross any main roads to get there.
If it's the Dunkins in Killingly Commons, I'd agree, that's tough to get to on foot and that intersection is awful.
