IIRC, in Michael Capuzzo's Murder Room (non-fiction about the Vidocq Society based in Philly), he ends the book with Society members going to interview a suspect in Marshall's Creek, PA (near Stroudsburg). Its been a while, but the suspect was either the (then young) man who set animal traps near where the body was found or the man who found the body.

It is weird to think, but that whole area around Verree Road was just woods then (still plenty of woods with Pennypack park), and I get a chill thinking about the Boy any time I'm in the area.
