In 1979, Simmons retired as an Air Force Master Sergeant following 20 years of service. The instability that followed his military days exacerbated his desire for control over his family. Simmons used intimidation, humiliation, and violence to assert dominance over all but one of his family members. He allowed a softer side to surface for his favourite daughter, Shelia, whom he forced into an incestuous relationship and eventually fathered her child. His need for total control led to isolation within his family and an inability to hold down a job. His frustration grew to untold levels when Sheila left the family home and married another man. With his plans in ruin and his grip softening, Simmons surprisingly supported his family's desire for a big Christmas celebration. The stage was set for a heartwarming reunion but he had laid a very different set of plans. Obeying Evil is a terrifying account of Ronald Gene Simmons and one of the most disturbing family killing sprees in the United States. Ryan Green’s riveting narrative draws the reader into the real-live horror experienced by the victims and has all the elements of a classic thriller.
