Serial killer cases are among the most studied and most chilling categories in criminal history. Defined by the FBI as the unlawful killing of two or more victims by the same offender in separate events, serial murder has fascinated criminologists, law enforcement professionals, and the public for over a century. These cases often span years or decades, crossing jurisdictional boundaries and leaving investigators with complex webs of evidence to untangle. CaseSleuth documents each serial killer case with victim timelines, investigation milestones, forensic evidence breakdowns, and profiles of both the perpetrators and the investigators who pursued them. From historically infamous cases to recently identified serial offenders, this collection provides comprehensive, fact-based coverage designed to inform rather than sensationalize.
