15 Infamous U.S. Serial Killers: Verified Timelines of Their Deadly Spree
In the annals of American crime, few figures evoke more dread than serial killers—those who methodically prey on the vulnerable over extended periods. The United States has been home to some of the most prolific and cunning, responsible for hundreds of confirmed victims. This article examines 15 real serial killers, drawing exclusively from verified timelines sourced from court records, FBI reports, and official investigations. By focusing on factual chronologies, we honor the victims, analyze patterns in their crimes, and highlight the evolution of law enforcement that ultimately brought many to justice.
These timelines reveal chilling consistencies: escalation from opportunistic kills to ritualized murders, geographic mobility, and psychological taunts. Yet they also underscore triumphs—advances in behavioral profiling, DNA forensics, and inter-agency cooperation. Far from glorifying these monsters, our goal is analytical: to understand the mechanics of detection and prevention, ensuring the stories of the lost are not forgotten amid the horror.
From the charming deceiver Ted Bundy to the elusive Zodiac, each profile below details confirmed activity spans, key murders, investigative breakthroughs, and outcomes. All data is corroborated by primary sources like trial transcripts and law enforcement archives.

Conclusion
These 15 serial killers’ verified timelines—from Bundy’s cross-country terror to DeAngelo’s decades-long evasion—illustrate the scale of evil confronted by American justice. Collectively, they claimed over 250 lives, shattering families and communities. Yet each downfall advanced criminology: from eyewitnesses and fibers to DNA revolutions. Victims like Lynda Healy, Stacy Moskowitz, and countless others deserve remembrance, not infamy overshadowed by killers. Modern tools like ViCAP databases prevent repeats, but vigilance endures. These stories remind us: patterns emerge, evil hides, but persistence prevails.
