Coconino County, Arizona · July 1937

The case Flagstaff kept in the drawer

In July 1937, one of Flagstaff’s most prominent families was lost in a single night, at the mother’s hand. Susan Johnson’s book is the first full account of the Walkup case: reconstructed from the record, told with care, and honest about what can never be known.

About the Book

History, not spectacle

From the publisher: In the summer of 1937, the mountain town of Flagstaff emerged from the Great Depression with an eye toward the future. Few people were better positioned for success than JD Walkup, a handsome young mover and shaker who served as chairman of the board of supervisors and a happily married father of four. But JD’s life changed forever one cool summer evening when his wife, Marie, and their children were found dead. The murders shook the town to its core, along with the disturbing knowledge that Marie was the culprit.

Readers consistently note the same two things about this book: how much Flagstaff context it carries, and how carefully it refuses to guess where the record is silent. That is by design. The family at its center deserves nothing less.
