Matthew "Mack" Harrison Marsden (1849–1883) was a livestock trader who lived in rural Jefferson County, Missouri.
 Marsden was suspected of many crimes from 1881 to 1883, including arson, murder, and robbery.
 Though he was often accused, questioned, and arrested, he was only brought to trial one time, and was acquitted.
 Marsden’s family background gave no hint of criminal activity.
 On the contrary, he came from an established family of farmers, engineers, and stockmen, and his wife’s family members were known as leaders in the local church.
 His story came to an end when he was murdered, and though four different men were arrested, and three of them tried for the killing, no one was ever convicted.
 Mack’s suspected killers left the county, the murder remained unsolved, and Marsden’s death corresponded with the end of a years-long crime spree.
 Newspapers suggested that his killing was a service to the community, and for decades, people continued to believe he was behind a gang that committed a long series of unsolved crimes.

Jacqueline Mary Thomas (1945 or 1946 – 18 August 1961) was a 15-year-old biscuit factory worker from Alum Rock, Birmingham, England who was sexually assaulted and strangled after disappearing on 18 August 1961.
 Her body was discovered a week later close to her home, and the murder sparked a manhunt involving several hundred police officers.
 A suspect was identified at the time, but there was insufficient evidence to charge him, and the crime remained unsolved for over four decades until a cold case review in the 2000s.
 In 2007, 70-year-old Anthony Hall – already serving a life sentence for the murder of another teenager – was charged with Thomas's murder.
 However, a judge subsequently ruled the charge should be stayed owing to the length of time that had passed since the incident.
