Sir James Tyrrell (c. 1455 – 6 May 1502) was an English knight, a trusted servant of King Richard III of England.
 He is known for allegedly confessing to the murders of the Princes in the Tower under Richard's orders.

Allan Grimson (born 1958) is a convicted British murderer who is responsible for murdering at least two men and is suspected of killing others, possibly up to another 20 undiscovered victims.
 The judge, who sentenced him to a minimum term of 22 years at his trial, said that Grimson was a serial killer by nature, but not by number.
 Because his two victims were killed on the same date just a year apart (12 December), detectives believe there may be more victims out there as yet unidentified.
"The Princes in the Tower" is an expression frequently used to refer to Edward V, King of England and Richard of Shrewsbury, Duke of York.
 The two brothers were the only sons of Edward IV of England and Elizabeth Woodville surviving at the time of their father's death in 1483.
 When they were 12 and 9 years old, respectively, they were lodged in the Tower of London by the man appointed to look after them, their uncle, the Lord Protector: Richard, Duke of Gloucester.
 This was supposedly in preparation for Edward's forthcoming coronation as king.
 However, Richard took the throne for himself and the boys disappeared.

Elizabeth Lloyd King (born 1847) was the alleged murderer of Charles Goodrich, whom she is said to have shot three times in the head on 20 March 1873 in Brooklyn, New York, United States.
 The murder was headline news in the city, until her capture more than three months after the event.
 Her inquest drew large crowds, and prisoner church sermons drew requests for attendance from the general public, some of whom were granted entry.
 After a year in jail, a psychological assessment deemed that she was unfit to stand trial, and she was committed to a life sentence at the State Lunatic Hospital at Auburn.

Henri Theodore Young (born June 20, 1911 – missing since 1972) was a convicted bank robber and murderer who, while serving one of a series of prison terms, attempted a 1939 escape from Alcatraz Federal Penitentiary with four other inmates.
 Two escapees were shot, and one died of his wounds; all surviving were quickly recaptured.
 Two at least, Young and Rufus McCain, received sentences of solitary confinement, and served them at Alcatraz for a period of a three year (until autumn of 1942).
 A little over three year after his reentering the Alcatraz general prison population (in December 1942), Young murdered fellow escapee McCain; no apparent motive was ever disclosed.
 Young's subsequent trial featured a spirited, creative defense that put Alcatraz and the penal system on trial, leading to questions about how the prison was run.
 Young was transferred from Alcatraz to the Medical Center for Federal Prisoners, Springfield, Missouri, in 1948, and then to Washington State Penitentiary at Walla Walla on completion of his federal sentence, to begin a life sentence for the 1933 murder conviction.
