Over a three-decade span, more than twenty women-many teenagers-died mysteriously in the small towns bordering Interstate 45, a fifty-mile stretch of highway running from Houston to Galveston. The victims were strangled, shot, or savagely beaten. The day she vanished, Colette Wilson waited for her mother after band practice. Best friends Debbie Ackerman and Maria Johnson loved to surf and were last seen hitchhiking. Laura Kate Smither dreamed of becoming a ballerina and disappeared just weeks before her thirteenth birthday. In this harrowing true crime exposition, award-winning journalist Kathryn Casey tracks these tragic cases, investigates the evidence, interviews the suspects, and pulls back the cloak of secrecy in search of elusive answers.
