Yes, the closed camp is tragic in its own right, like a monument to a loss of innocence. I vividly remember how my own camp experience was impacted by this: a full fence surrounding the place, a 24/7 guard at the one and only gate, and leaders/mothers in the cabin with us. (I'm not complaining -- I fully understand why families and organizations felt the need for this security after a nightmare like these killings in our backyard -- but these measures kept the murders in our minds in a constant way. It was as if our secure world overnight had been rendered permanently unsafe.)

I agree with you about the movie. The filmmaker has claimed he's using this as a vehicle for proposing his own alternate suspect, but it sounds like a gimmick to me. If he ever knew something useful about the crimes, the right thing to do would have been to talk immediately to anyone/everyone who would listen, not use it as a hook to sell tickets. Apparently this has dragged on so long that the suspect in question has died, which adds a layer of futility to the whole thing, too. (Not that knowing the truth is ever futile, of course, but it's a little late for the justice system to step in if the suspect is deceased.)
