Book excerpt: From the horrific Enoch Brown Schoolhouse Massacre of 1764 to settlers who hunted local tribes for a bounty, Cumberland County, Pennsylvania, has long had a violent and bloody history. As more people came to the region, murder and mischief of every kind only multiplied. Local author Joseph David Cress explores the dark side of history, from little-known cases such as that of Sarah Clark--who became the first woman hanged in the county after she poisoned a family to dispatch a romantic rival--to high-profile crimes like the shocking 1955 courtroom slaying that left one person dead and three injured. Join Cress on a hair-raising walk down Hell Street as he investigates the underbelly of Cumberland County.
