Executed Killers

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.

James Dupree Henry was convicted of murdering 81-year-old Orlando civil rights leader Zellie Riley during a robbery at Riley's home in March 1974. Henry bound and gagged Riley before suffocating him and stealing property from the residence. Five days later, Henry shot and seriously wounded Orlando police detective Ronald Ferguson while attempting to avoid arrest. Convicted of first-degree murder and sentenced to death, Henry maintained his innocence throughout his decade on death row. His case became the focus of civil rights and capital-punishment campaigns, with Jesse Jackson, Coretta Scott King and Riley's son asking Florida officials for clemency. Henry was executed by electrocution at Florida State Prison on September 20, 1984.

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 George Haigh, known as the Acid Bath Murderer, was an English serial killer who murdered six people between 1944 and 1949, although he claimed responsibility for three additional killings that could not be substantiated. Haigh targeted people he believed could provide him with financial gain, killing them before dissolving their bodies in concentrated sulphuric acid and exploiting their property and possessions. His final victim, wealthy widow Olive Durand-Deacon, was murdered at his workshop in Crawley, where investigators subsequently discovered human remains and other evidence linking him to the killings. Convicted of murder at Lewes Assizes in July 1949, Haigh was sentenced to death and hanged at Wandsworth Prison on 10 August 1949.

John Arthur Spenkelink was a convicted robber and prison escapee who murdered Joseph Szymankiewicz in a Tallahassee, Florida, motel room in February 1973. Spenkelink shot Szymankiewicz twice while he was in bed and then attempted to delay discovery of the body by giving the motel proprietor a false account before leaving the area. He claimed the killing was self-defence, alleging that Szymankiewicz had robbed and sexually assaulted him, but prosecutors established that the murder was premeditated. Convicted of first-degree murder and sentenced to death, Spenkelink became a major figure in the American death-penalty debate after capital punishment was reinstated. Following years of appeals and stays, he was executed by electrocution at Florida State Prison on May 25, 1979, becoming the first person involuntarily executed in the United States after the modern resumption of capital punishment.

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. Gacy’s case gained notoriety due to the scale of his offences and the contrast between his outward persona and his actions. He was later convicted and sentenced to death, becoming one of the most infamous serial killers in U.S. history.

Robert Austin Sullivan was convicted of murdering Donald Schmidt, the manager of a Howard Johnson's restaurant in Homestead, Florida, during a robbery in April 1973. Sullivan and accomplice Reid McLaughlin abducted Schmidt, bound him and drove him to a remote area, where he was shot twice in the head with a shotgun. Sullivan initially confessed to the murder before later recanting and maintaining his innocence. Convicted of first-degree murder and robbery, he was sentenced to death and spent ten years on Florida's death row. Despite numerous appeals and pleas for clemency, including an intervention by Pope John Paul II, Sullivan was executed by electrocution at Florida State Prison on November 30, 1983.

Stanley "Tookie" Williams was an influential Los Angeles gang figure who co-founded the Crips with Raymond Washington before being convicted of four murders committed during two robberies in 1979. Sentenced to death in 1981, Williams spent more than two decades on California's death row while consistently maintaining his innocence of the murders. During his imprisonment, he renounced gang life, wrote books warning young people about gangs and became an anti-gang activist whose work attracted international attention and Nobel Peace Prize nominations. His supporters sought clemency based on his claimed rehabilitation, but California Governor Arnold Schwarzenegger rejected the request, and Williams was executed by lethal injection at San Quentin State Prison on December 13, 2005.
