The reanalysis of the Brearley (1932) data using spectral analysis demonstrates that a significant seasonal dependency for homicide exists, peaks in August, and explains between 23 percent and 30 percent of the nonlinear variation in homicide deaths. The most important aspect of the results is the phase stability of the determined rhythm over time. Brearley analyzed FBI Uniform Crime Reports of 51,798 United States homicides between 1923 and 1928. Although he generally found a summer excess, the overall dispersion of the data led him to conclude that there was no consistent seasonal effect. The original data from Brearley’s analysis was reanalyzed using spectral analysis. Tables, figures, references
