The One Eyed Sheriff by Vince Onken

Is he real or is he folklore? Either way bad things happen when two teens start digging into the almost forgotten local legend of the One Eyed Sheriff. Ethan and Lauren are in search of the truth, and as far as they can tell the truth lies somewhere in the darkest recesses of Drury Woods. And since the One Eyed Sheriff allegedly shows up only once every twenty years, most of the townsfolk have forgotten about him or think the urban legend is just that, yet according to two well-informed authorities every twenty years for the last hundred years teens have gone missing on Halloween, never to be seen or heard from again. Horror sci-fi comedy.
