Seriously? This seems a little vague. ‘At least 20’ victims? You can’t even be bothered to be exact? All in this neighbourhood? All children you knew?
What evidence is offered for this serious accusation?
Should we be concerned that your daughter has neither memory nor knowledge of this presumably notorious local hecatomb? (That is alleged to have occurred during her lifetime, you having even then been part of ‘a bunch of us parents’.)
Where are the bodies?
Are no eyebrows raised by the lasciviously drawn-out description of the grotesque & sadistic lynching? Do suspicions occur at the rote kitsch of your dutifully cited greedy-lawyers & incompetent-bureaucrats tropes?
Was it really unsigned paperwork that undermined this case? Or did you have no case?

Was he by any chance a loner? Stuck to himself? Never fit in?
From beyond the wall of sleep continues a remorseless campaign against a miscarriage of justice. Krueger is innocent.
