Modus Operandi - Shooting Individual

David Alan Gore was an American serial killer who, along with his cousin Fred Waterfield, committed at least six murders of women in and around Vero Beach, Florida, from 1981 to 1983. Known collectively as the "Killing Cousins," the pair exploited Gore's position as an auxiliary sheriff's deputy and his knowledge of local citrus groves to lure victims, often using a badge or vehicle to gain trust before subjecting them to sexual assault, torture, and murder.

Adolfo de Jesús Constanzo became one of Mexico's most notorious serial killers after leading a violent criminal cult that combined ritualistic beliefs with narcotics trafficking during the 1980s. Operating primarily in Mexico City and Matamoros, Constanzo and his followers carried out numerous murders as part of ceremonies they believed would provide supernatural protection and success. The discovery of multiple victims at his ranch in 1989 exposed one of the most disturbing criminal conspiracies in Mexican history.

Alphonse Gabriel "Al" Capone became one of the most notorious organized crime figures in American history after dominating Chicago's underworld during the Prohibition era. As the leader of the Chicago Outfit, Capone oversaw bootlegging, gambling, prostitution, extortion, and numerous violent crimes throughout the 1920s. Although strongly linked to many murders, including the infamous Saint Valentine's Day Massacre, Capone was ultimately convicted of tax evasion rather than homicide. His criminal empire and public notoriety made him one of the most recognizable gangsters of the twentieth century.

Thayne Ormsby is an American man convicted of a 2010 triple homicide in Maine. At the age of 20, he carried out a violent attack resulting in multiple deaths within a single incident. He was later arrested, convicted, and sentenced to life imprisonment without the possibility of parole.

Nicholas “Nick” Browning is an American man convicted of the 2008 murders of his parents and two younger brothers in Maryland. At the time of the offence, he was 15 years old and living in a suburban family environment. The case gained national attention due to the age of the offender and the deliberate nature of the killings. Browning was later convicted and sentenced to multiple life terms.

Ashley Britt McArthur murdered her friend, 33-year-old private investigator Taylor Wright, near Pensacola, Florida, in September 2017 after Wright sought the return of $34,000 she had entrusted to her for safekeeping. Prosecutors established that McArthur had already spent much of the money before taking Wright to her family's rural property in Cantonment, where she shot her and concealed her remains beneath concrete and potting soil. Cell-phone records, financial evidence and surveillance footage helped investigators reconstruct McArthur's movements. She was convicted of first-degree premeditated murder in August 2019 and sentenced to life imprisonment with a mandatory minimum of 25 years.

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.

Herbert William Mullin became one of California's most infamous serial killers after murdering 13 people in and around Santa Cruz between October 1972 and February 1973. Mullin later claimed he believed the killings were necessary to prevent catastrophic earthquakes, a delusion linked to severe mental illness. His short but deadly murder spree ended with his arrest in February 1973, and his case remains one of the most widely studied examples of psychosis and serial homicide in the United States.
