Bryan Kohberger is an American man charged in connection with the 2022 murders of four university students in Moscow, Idaho. At the time of the incident, he was a criminology PhD student at Washington State University, located a short distance from the crime scene. The case gained widespread national and international attention due to the number of victims, the nature of the attack, and Kohberger’s academic focus on criminal behaviour. He was arrested in December 2022, and legal proceedings are ongoing.

Rex Heuermann became one of America’s most infamous alleged serial killers after being charged in connection with the Gilgo Beach murders on Long Island. The architect from Massapequa Park shocked the United States because prosecutors alleged he secretly murdered multiple women for years while outwardly living as a married family man and successful New York professional. The Gilgo Beach investigation became one of the most heavily publicized serial killer cases in modern American history after human remains were discovered along Ocean Parkway near Long Island’s South Shore. Authorities later accused Heuermann of targeting vulnerable women, particularly sex workers, before allegedly carrying out murders over an extended period while avoiding detection for more than a decade.

Herman Webster Mudgett, better known as H.H. Holmes, became one of America's earliest infamous serial killers after carrying out a series of murders during the late nineteenth century. Operating from a specially designed building in Chicago that later became known as the "Murder Castle," Holmes used deception, fraud, and false identities to lure victims. Although he confessed to 27 murders before his execution, historians believe the true number of victims remains uncertain. His case remains one of the most famous in American criminal history.

Richard Francis Cottingham became one of the most infamous serial killers in American history after murdering numerous women and girls in New York and New Jersey between 1967 and 1980. Known as the "Torso Killer" because several victims were dismembered, Cottingham targeted women he encountered in hotels, bars, and areas associated with sex work. Following his arrest in 1980, he was convicted of multiple murders and later confessed to additional killings, making him one of the most prolific identified serial killers in the northeastern United States.

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.

Dennis Andrew Nilsen became one of the United Kingdom's most infamous serial killers after murdering at least 15 young men and boys in London between 1978 and 1983. Often referred to as the "Muswell Hill Murderer," Nilsen lured vulnerable victims to his home before strangling them and keeping their bodies for extended periods. His crimes were uncovered only after human remains blocked drains at his apartment building, leading to one of Britain's most shocking homicide investigations.

Rodney James Alcala became one of America's most infamous serial killers after murdering at least eight women and girls between 1971 and 1979, although investigators believe he may have killed well over 100 victims. Nicknamed the "Dating Game Killer" after appearing on the television show The Dating Game during his killing spree, Alcala used his charm and photography hobby to lure victims before murdering them. He was convicted in multiple states and died on California's death row in 2021.

Peter William Sutcliffe, known worldwide as the "Yorkshire Ripper," became one of the United Kingdom's most infamous serial killers after murdering 13 women and attempting to murder seven others between 1975 and 1980. Operating across Yorkshire and Greater Manchester, Sutcliffe evaded capture for more than five years despite one of the largest police investigations in British history. His crimes generated widespread fear, exposed major investigative failures, and permanently changed homicide investigations in the United Kingdom.
