Tyrone Werts is an American man who was convicted of a second-degree murder committed in 1975, for which he received a life sentence; however, he was released after 36 years instead.
 This was an extremely rare case as the law in Pennsylvania says that if you have been charged with 1st or 2nd degree murder and were given a life sentence, there is no possibility for parole (Gottschalk).
 He is most known as an ex-convict who was released from Prison after serving 36 years of what was supposed to be a life sentence.
 While serving his time at Graterford Prison, in Perkiomen, Pennsylvania, Werts served as the president of the “Lifers” and made many very influential and positive changes in the prison community.

Helmuth Buxbaum (March 19, 1939 — November 1, 2007) was a multimillionaire owner of a network of nursing homes in Ontario who was convicted in 1986 of the murder of his wife, two years previously.
 Hanna Buxbaum was found dead July 5, 1984 on a highway near London, Ontario after having been shot in the head three times.
 Helmuth Buxbaum had taken out a $1 million life insurance policy on his wife shortly before her murder.
 The Crown attorney prosecuting the case argued that Buxbaum had hired a hitman to kill his wife for $10,000 and had pulled over to the side of the road so that the man could drag her out of the car and shoot her.
 The gunman, Gary Foshay, was convicted of second degree murder.
 Buxbaum was convicted after a high-profile trial and sentenced to a life sentence without the possibility of parole for 25 years.
 He died in prison in Kingston, Ontario on November 1, 2007 at the age of 68.
In the United States, 1 in every 2,000 residents is imprisoned for life.
 This is similar to the total imprisonment rate in Japan, which is roughly 51 per 100,000 residents.
 There are many U.S. states where a convict can be released on parole after a decade or more has passed.
 For example, sentences of "15 years to life", "25 years to life", or "life with mercy" may be given; this is called an "indeterminate life sentence", while a sentence of "life without the possibility of parole" or "life without mercy" is called a "determinate life sentence".
 Even when a sentence specifically denies the possibility of parole, government officials may have the power to grant amnesty or reprieves, or commute a sentence to time served.

Sara Jessimy Kruzan (born January 8, 1978) is an American murderer.
 In 1995, at the age of 17, she was convicted of the first-degree murder of her pimp, George Gilbert Howard.
 She was sentenced to life imprisonment without parole, and as a result received national attention from individuals and judicial reform groups, who advocated for a new trial.
 On January 2, 2011, as a result of the media attention, Kruzan was granted clemency by Governor Arnold Schwarzenegger, who commuted her sentence to 25 years with the possibility of parole; she remained incarcerated at the Central California Women's Facility in Chowchilla.
 In January 2013, her sentence was reduced to second-degree manslaughter and 15 + 4 years, effectively time served, making her eligible for a parole hearing.
 She was found suitable for parole on June 12, 2013, and the decision was forwarded to Governor Jerry Brown.
 On October 25, 2013, Brown took no action on the parole board decision, thereby effectively confirming it, allowing the parole board to proceed with the parole of Kruzan.
 On October 31, 2013, she was paroled from Central California Women’s Facility in Chowchilla after serving 19 years.
