Craig Mulligan became one of the United Kingdom’s most shocking juvenile killers after being convicted for his role in the murder of a five-year-old child in South Wales in 2021. The case horrified Britain because Mulligan was only 13 years old at the time of the killing, making him one of the youngest convicted murderers in modern Welsh criminal history. The investigation generated enormous public outrage after details emerged about abuse inside the household, repeated safeguarding failures and warnings allegedly ignored by authorities before the murder occurred. The case later became one of Britain’s most disturbing examples of child-on-child violence combined with systemic failures involving social services and child protection agencies.

Curtis Wayne Wright became known in American criminal history after participating in the 2015 murder-for-hire of Dr. Teresa Sievers in Bonita Springs, Florida. A longtime friend of Teresa's husband, Mark Sievers, Wright helped plan the killing before recruiting Jimmy Rodgers to assist in carrying out the attack. Wright later pleaded guilty, cooperated with prosecutors, and testified against both Rodgers and Mark Sievers, making him the key witness in one of Florida's most high-profile murder-for-hire cases.

Dale Bradley Jr. was convicted of killing 22-year-old Kennecott security guard Bryan Ruff in Utah in December 1991. Ruff, who was having an affair with Bradley's first wife, Kristi, disappeared from his guard post during a night shift and was found nearly 19 months later in a shallow grave near Five Mile Pass. Investigators eventually linked Bradley to the killing through physical evidence and witness testimony. Bradley originally faced a first-degree murder charge but entered an Alford plea to manslaughter and kidnapping in 2007 and received two consecutive prison terms of two to 20 years. In 2025, while seeking parole, Bradley finally admitted that he shot Ruff, saying anger and jealousy had overtaken him.

Damian Rzeszowski was convicted of six counts of manslaughter after killing his wife Izabela, their children Kinga and Kacper, his father-in-law Marek Garstka, and family friend Marta de la Haye and her daughter Julia in St Helier, Jersey, on August 14, 2011. Rzeszowski attacked the victims with kitchen knives during a violent episode following the breakdown of his marriage. His defence successfully argued diminished responsibility caused by severe depression and psychotic symptoms, and he was cleared of murder. He was sentenced to 30 years imprisonment for each victim, to run concurrently. Rzeszowski died by suicide in prison in 2018.

Daniel Charles "Dan" Howard, a former Idaho State Police trooper, murdered his wife Kendy Howard at their home in Athol, Idaho, on February 2, 2021, before staging the scene to make her death appear to be a suicide.

After a two-year investigation, Howard was charged with murder and convicted of second-degree murder and domestic battery in March 2024. He was sentenced to life imprisonment without the possibility of parole in May 2024.
