Chapter 1: Dead Certain
Since the mid 1990’s, in the northernmost district of America where Interstates 90 and 94 merge to cut a scenic route toward the west, crossing nearly a dozen states along the way and skirting the border with Canada, scores of young men are vanishing every year without a trace. Only to turn up days, weeks, or months later in nearby bodies of water, dead.
Occurring mainly between the months of September to April, it’s the same story repeating itself every time, with little variation: A young man goes out for the evening with his friends, gets separated from them some time after midnight, and, despite massive search efforts by his loved ones to find out what became of him, is never seen alive again.
