Shane Devon Tamura became the perpetrator of one of New York City's deadliest shootings in decades after opening fire inside a Midtown Manhattan office tower on July 28, 2025. The attack killed four people and injured several others before Tamura died by suicide.

Shelby John Nealy killed his wife, Jamie Ivancic, in Florida in 2018 and concealed her death while impersonating her through messages to her family. As Jamie's relatives became increasingly suspicious, Nealy travelled to their Tarpon Springs home and murdered her parents, Richard and Laura Ivancic, and her brother, Nicholas Ivancic, in December 2018. He was arrested in Ohio in January 2019 with his two young children and later pleaded guilty to charges arising from all four deaths. Nealy received a 30-year prison sentence for Jamie's death and, following separate penalty proceedings for the three Ivancic family murders, was sentenced to death in April 2026.

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.

Stephen William Beal killed his former girlfriend and business partner Ildiko Krajnyak with a package bomb planted inside their day spa in Aliso Viejo, California, on May 15, 2018. The explosion killed Krajnyak and seriously injured two clients, triggering a lengthy federal investigation that focused on Beal's explosives knowledge and evidence recovered from his Long Beach home. After an initial arrest, release and later rearrest, Beal faced federal prosecution and a 2022 mistrial before being convicted at retrial in 2023. He was sentenced in January 2024 to life imprisonment plus an additional 30 years.

Stephen-Alan Paul Nicholson was convicted of murdering 13-year-old Lucy McHugh in Southampton, England, in July 2018. Nicholson, who had been living as a lodger in Lucy's family home, had sexually abused her for more than a year before luring her to woodland near Southampton Sports Centre, where he stabbed her 27 times. Prosecutors said Lucy had threatened to expose the abuse, giving Nicholson a motive to silence her. He was also convicted of three counts of rape involving Lucy and sexual offences against another teenage girl. In July 2019, Nicholson was sentenced to life imprisonment with a minimum term of 33 years.

Stephen Port, widely referred to as the Grindr Killer, was a British serial killer who targeted young men he met through online dating platforms, particularly Grindr. Operating in London between 2014 and 2015, he used deception to lure victims to his home, where he drugged them with lethal doses of GHB before sexually assaulting and murdering them. Port’s crimes were marked by manipulation and calculated staging, often disposing of victims’ bodies in or near public areas and attempting to mislead police by planting false evidence. His actions exposed serious investigative failures by authorities, as opportunities to stop him earlier were missed. He was eventually arrested, convicted, and sentenced to life imprisonment.
