August 31, 1969 - Andrew Cunanan

Over the course of three months in 1997, Cunanan crossed the country leaving five people dead before culminating his spree with the high-profile killing of Gianni Versace outside his Miami Beach home — a crime that drew international attention and intensified the nationwide manhunt already underway. What made his case particularly unsettling to investigators was the apparent absence of a single motive connecting his victims, who ranged from close acquaintances to a stranger, suggesting a pattern driven by opportunity and escalation rather than any coherent grievance.
