Question: Reference Re Ng Extradition held that it was permissible to extradite this serial killer who was born in what year?
Context: Kindler v Canada (Minister of Justice) was a landmark decision of the Supreme Court of Canada where it was held that the government policy that allowed for extradition of convicted criminals to a country where they may face the death penalty was valid under the Canadian Charter of Rights and Freedoms.  The Court repeated this finding in "Reference re Ng Extradition" in 1991.  However, "Kindler" was essentially overruled in 2001 with "United States v. Burns". The Sun Hill Serial Killer was a major storyline from ITV's cop show "The Bill".  Known originally as the "River Murders", the storyline spanned several months in 2002 and served as the exit for popular cast regular Cass Rickman (played by Suzanne Maddock).  It was the first of several serial killer storylines from the show.  Events came to a head in the New Year of 2003, when Acting DI Samantha Nixon discovers the truth and is taken hostage by the serial killer, before a final confrontation in which she is overpowered by DC Duncan Lennox, charged and thrown into the cells at Sun Hill Station. Extradition law in the United States is the formal process by which a fugitive found in the United States is surrendered to another country or state for trial or punishment.  For foreign countries, the process is regulated by treaty and conducted between the federal government of the United States and the government of a foreign country.  The process is considerably different from interstate or intrastate extradition.  Florida, Alaska, and Hawaii do not extradite for a misdemeanor conviction that was convicted in the US, as of 2010.  Some felonies are an exception in American law such as a crime that is violent in nature, or a sexual offense, or felony driving while intoxicated; they will entail extradition from all states in the United States.  Theft charges and small drug crimes are the exception; for instance, if a minor crime is committed in Florida, a person apprehended in Idaho will not be extradited back to the original crime's jurisdiction.  Federal charges are governed by US federal law and most states, with the exceptions of South Carolina and Missouri, have adopted the Uniform Criminal Extradition Act.  In practice, Florida, Alaska, and Hawaii typically do not extradite if the crime in question is not a felony because of the associated costs of transporting the suspect and the housing fees that must be paid to the jurisdiction in which he is held until transported. Valentine v. United States, 299 U.S. 5 (1936), is known in the study of international criminal law for its contribution to the concept that while it is permissible for the United States to receive an accused without a treaty-based extradition, the United States itself will not extradite without authority found in statute or treaty. My Brother the Serial Killer is a 2012 American television documentary about serial killer Glen Rogers, otherwise known as the "Casanova Killer", who was convicted for a series of murders and arsons.  The documentary was narrated by Rogers' brother Clay Rogers and aired on Investigation Discovery in November 2012.  "My Brother the Serial Killer" received widespread media attention for Clay's claims that his brother was responsible for the 1994 murders of Nicole Brown Simpson and Ronald Lyle Goldman. Charles Edmund Cullen (born February 22, 1960) is a former nurse who is the most prolific serial killer in New Jersey history and is suspected to be the most prolific serial killer in American history.  He confessed to authorities that he killed up to 40 patients during the course of his 16-year nursing career.  But in subsequent interviews with police, psychiatric professionals, and journalists Charles Graeber and Steve Kroft, it became clear that he had killed many more, whom he could not specifically remember by name, though he could often remember details of their case.  Experts have estimated that Charles Cullen may ultimately be responsible for 400 deaths, which would make him the most prolific serial killer in American history. Kurt Sonnenfeld (born 1962) is an American granted political asylum in Argentina after he demonstrated to the president of Argentina and other high ranking officials that there had to have been foreknowledge of the 9/11 attacks because, among other things, the massive gold vaults at World Trade Center 6 had already been opened and emptied of their contents before the attack.  Sonnenfeld had been employed as a videographer for the U.S. Federal Emergency Management Agency (FEMA) and had unusual authority to document the rubble scene at the World Trade Center site immediately after the September 11 attacks in New York in 2001.  He made a total of 29 videos but did not turn all of them over to FEMA.  On New Year's Eve 2001, at his Colorado home, Sonnenfeld's wife Nancy died of a point blank gunshot to the head and Sonnenfeld was arrested for her murder.  In 2002 the murder charges were dropped for lack of evidence but the prosecutor reserved the right to refile the charges.  Sonnenfeld departed for Argentina soon thereafter, had his 9/11 videos sent to Argentina along with his personal belongings, remarried to an Argentine and had children.  After a voluntary visit to the US embassy in Buenos Aires to secure a visa for his new wife, the US federal government made the first of numerous attempts to extradite him back to the US for the 2001 murder of his wife Nancy, notwithstanding the Colorado court's decision not to prosecute him for the murder.  The Argentine government cited its opposition to the death penalty in its denial of the extradition requests.  Sonnenfeld insists that the US government is using the death of his wife Nancy to get at him for not handing over all the videos, which he has stated prove that the official 9/11 narrative of a surprise attack is false. Reference Re Ng Extradition was a 1991 case in which the Supreme Court of Canada held that it was permissible to extradite Charles Ng, a fugitive, to the United States, where he was wanted on charges of several murders and might face the death penalty.  The issue came before the court in the form of a reference from the government; the federal government asked the court for an advisory opinion as to whether the extradition of a fugitive threatened with execution would violate the Canadian Charter of Rights and Freedoms. Charles Ng Chi-Tat (; born December 24, 1960 in Hong Kong) is a serial killer who operated in the United States.  He is believed to have raped, tortured and murdered between 11 and 25 victims with his accomplice Leonard Lake at Lake's cabin in Calaveras County, California, in the Sierra Nevada foothills 150 miles east of San Francisco. Luis Alfredo Garavito Cubillos, also known as "La Bestia" ("The Beast") or "Tribilín" (named after Disney character "Goofy"'s Latin American Spanish name) is a Colombian rapist and serial killer.  In 1999, he admitted to the rape, torture and murder of 147 young boys.  His victims, based on the locations of skeletons listed on maps that Garavito drew in prison, could eventually exceed 300; Garavito continues to confess to more murders.  He has been described by local media as "the world's worst serial killer".  According to the Attorney General's Office and various judicial bodies, Luis Alfredo Garavito is the "second serial killer of the world."  Likewise, the judicial body ruled that all Garavito's sentences total 1853 years and nine days in jail.
