A night of violence shakes a small Ohio town to its core when eight family members—the Rhodens—are shot to death in their sleep in 2016. Their ages range from 44 to 16 with five males and three females—including two young moms with their babies nearby. David Raterman, a journalist who grew up 90 miles away, decides to investigate what the local sheriff calls “a heinous crime that’s never been seen before.” And what he discovers is not only shocking but also a true whodunit.
