What a different world this sad accident took place in! Who can imagine a firearm in a P.A. student's possession today? It's equally hard to imagine that Hilton would have fared well with Riggs's revolver if faced with a threat of violence on his journey home. One really has to wish that guns weren't so readily available at any time, in any place.
A quick internet search reveals that Tracy, age sixteen, was buried close to his family home, in New Rochelle, New York, while Riggs, who died six years later at age twenty-three, was buried in Emporia. There's no way for me to learn the cause of Riggs's death, but he and Tracy were described in the Bulletin as "warm friends and constant companions."
