In 1954, two college students were hiking along a creek outside of Boulder, Colorado, when they stumbled upon the body of a murdered young woman. Who was this woman? What had happened to her? The initial investigation turned up nothing, and the girl was buried in a local cemetery with a gravestone that read, "Jane Doe, April 1954, Age About 20 Years." Decades later, historian Silvia Pettem formed a partnership with law enforcement and forensic experts and set in motion the events that led to Jane Doe's exhumation and eventual identification, as well as the identity of her probable killer. The 2023 paperback edition includes an epilogue with updated information on how the mystery finally was solved.
