Scott Dozier was born on November 20, 1970, in Boulder City, Nevada. His father worked for federal water projects throughout the American West and he had two siblings.
In his adulthood, Dozier briefly served in the United States Military, and married Angela Drake whom he had begun dating in high school, and had a son from that marriage. By his mid-20s, he was making much of his income from the production and sale of methamphetamine, during the course of which he would alternate between Nevada and Arizona, the two states in which he was convicted of murder. Dozier had commented on his enjoyment of "living outside the law" in the months leading up to his scheduled execution.
