The history of true crime is filled with infamous names, but fame doesn’t always reflect the true scale of a killer’s crimes. Some of the deadliest serial killers in history weren’t household names — they operated in silence, preying on the most vulnerable and leaving behind staggering numbers of victims. Their crimes were often hidden in plain sight, overlooked by society, or difficult for authorities to fully uncover.
This list highlights the killers responsible for the highest known body counts, individuals whose actions shocked the world and left an indelible mark on history. Many of their victims were never found, and some cases remain unresolved to this day, a chilling reminder of how ordinary people can commit unimaginable horrors.
6. Elizabeth Báthory – “The Blood Countess”
Estimated victims: 80–650
Active years: Late 1500s–early 1600s
Country: Hungary
Elizabeth Báthory, a Hungarian noblewoman, is often referred to as “The Blood Countess.” She is infamous for allegedly torturing and killing hundreds of young women over many years.
Historical records suggest she believed bathing in the blood of virgins would preserve her youth and beauty.
Her crimes were discovered after testimonies from servants and survivors, and she was eventually confined to her castle until her death. The true number of her victims remains unknown, with estimates ranging widely due to the scarcity and unreliability of 16th-century records. Despite this, Báthory’s story has become legend, a chilling tale of privilege, power, and unchecked cruelty.
7. Andrei Chikatilo – “The Butcher of Rostov”
Confirmed victims: 52
Suspected victims: 60+
Active years: 1978–1990
Country: Soviet Union
Andrei Chikatilo terrorized the Soviet Union for over a decade, targeting women and children. Known as “The Butcher of Rostov,” he lured victims into isolated areas, murdered them, and often mutilated their bodies. His methods included stabbing, strangulation, and sexual assault, making his crimes particularly horrifying.
Chikatilo evaded capture for years due to lax investigative procedures and the lack of communication between authorities in different regions. He was finally caught in 1990 after forensic advancements and meticulous police work connected him to multiple murders. He was executed in 1994, leaving behind a legacy of fear that still haunts Russia’s criminal history.
8. Samuel Little – “America’s Most Prolific Serial Killer”
Confirmed victims: 60
Confessed victims: 93
Active years: 1970–2005
Country: United States
Samuel Little is considered the most prolific serial killer in United States history. Over the course of 35 years, he murdered dozens of women, many of whom were marginalized, vulnerable, or living on the streets. Little’s confessions, which were verified by law enforcement, revealed a calculated and methodical killer who meticulously tracked his victims.
Despite his crimes spanning decades, Little often went unnoticed by authorities. His ability to avoid detection was aided by societal blind spots — many of his victims were overlooked or assumed to be missing without investigation. His confessions and case studies have since
provided valuable insight into serial criminal behavior, victimology, and the systemic failures that allowed him to continue killing for so long.
9. Mikhail Popkov – “The Werewolf”
Confirmed victims: 83
Active years: 1992–2010 Country: Russia
Mikhail Popkov, a former police officer in Siberia, is one of Russia’s deadliest known serial killers. Known as “The Werewolf,” he used his position of authority to gain the trust of women, often offering rides or assistance before attacking them in remote locations. Popkov murdered dozens over nearly two decades, employing strangulation and bludgeoning as his primary methods.
After his arrest, further confessions revealed the extent of his crimes, which were previously underestimated. Popkov’s case is particularly chilling because he exploited his position in law enforcement to evade suspicion, demonstrating how power and authority can be abused by those with malicious intent.
10. Yang Xinhai – “The Monster Killer”
Confirmed victims: 67
Active years: 1999–2003
Country: China
Yang Xinhai, dubbed “The Monster Killer,” committed a series of brutal murders in rural China, targeting entire households in a methodical, merciless manner. He used axes, hammers, and knives to kill men, women, and children alike, often attacking multiple victims in a single incident.
Yang’s crimes were carried out with shocking precision, and he moved from village to village, leaving communities traumatized and law enforcement struggling to respond. He was eventually captured and executed in 2004. His case remains one of the deadliest and most notorious in modern Chinese criminal history.
