Justin Jason Keeding, widely known as the “Little Merchant Killer,” became one of the more notorious robbery-murder offenders of the early twentieth century after being linked to violent attacks against rural merchants and storekeepers. Operating during the 1920s, Keeding allegedly targeted isolated business owners in smaller communities, earning his nickname through repeated attacks connected to robbery and financial gain. The case generated significant regional media attention during the era because of the fear surrounding traveling offenders targeting small-town businesses. Authorities portrayed Keeding as a violent drifter willing to kill during robberies, while newspapers sensationalized the crimes through dramatic reporting common during the period. His eventual death in 1926 closed a violent criminal chapter that remained part of regional crime history for years afterward.

Jack the Ripper is an unidentified serial killer responsible for a series of murders in the Whitechapel district of London in 1888. His crimes shocked Victorian society and became one of the most infamous unsolved cases in criminal history.

His ability to evade capture, combined with the brutality of the crimes and widespread media attention, has cemented his place as one of history’s most enduring criminal figures.

Jeffrey Dahmer is one of the most disturbing figures in American criminal history, often dubbed the “Milwaukee Cannibal.” Between 1978 and 1991, he carried out a series of brutal murders involving necrophilia, cannibalism, and body preservation.

John Reginald Halliday Christie became one of the United Kingdom's most infamous serial killers after murdering multiple women, including his wife, at his home in Notting Hill, London, during the 1940s and early 1950s. His crimes, committed at 10 Rillington Place, led to one of Britain's greatest miscarriages of justice when Timothy Evans was wrongly convicted and executed before Christie's guilt was uncovered. The case remains one of the most significant in British criminal history.

John Wayne Gacy was an American serial killer and sex offender who murdered multiple victims in Illinois during the 1970s. He became widely known for maintaining a public image as a community figure while committing crimes in secret.

Joseph James DeAngelo, known as the "Golden State Killer," became one of the most infamous serial offenders in American history after committing a series of murders, rapes, and burglaries across California between 1974 and 1986. A former police officer, DeAngelo evaded identification for more than 40 years before investigators used investigative genetic genealogy to identify and arrest him in 2018. His case transformed modern criminal investigations and demonstrated the power of forensic DNA technology in solving long-unsolved crimes.

Michael Swango became one of the most notorious medical serial killers in American history after being linked to a series of poisonings involving patients, coworkers, and acquaintances over several decades. A licensed physician and former paramedic, Swango exploited positions within hospitals and medical institutions to gain access to vulnerable victims while maintaining the outward image of a highly educated healthcare professional. The case generated international attention because Swango continued obtaining medical employment despite repeated suspicions, disciplinary actions, and criminal convictions. Investigators later connected him to deaths and poisonings across the United States and Africa, leading many experts to believe the true number of victims may never be fully known. His ability to repeatedly evade detection turned the case into one of the most disturbing examples of institutional failure and medical predation in modern criminal history.
