On the night of June 8, 1987, a home invasion in Yuma, Arizona, ended with the fatal shooting of Sterleen Hill, a Black woman. Two men forced their way into the Hill residence, bound Sterleen and her husband, Ralph Hill, and forced them to lie face down. The intruders ransacked the bedroom, demanding money and drugs while searching for the Hills’ daughter, who had recently left her common-law husband, Fred Robinson.

During the assault one of the men shot Ralph Hill in the head with a shotgun; he survived despite serious injuries. After reloading, the assailant shot Sterleen Hill execution-style, killing her. The family’s teenage son escaped and alerted a neighbor, and police soon arrested Fred Robinson, Theodore Washington, and Jimmy Mathers. The three were charged with first-degree murder, attempted murder, aggravated assault, burglary, and armed robbery; they were later found guilty on all counts and sentenced to death.

What details about that night or the people involved might help explain how the intruders located the Hill family’s home?
