Question: Who was found guilty of killing 22 villagers and originally given a life sentence but was released after a ruling by federal judge found their trial has been prejudiced by pre-trail publicity?

<P0-S0> The Mỹ Lai Massacre (Vietnamese: "Thảm sát Mỹ Lai" , ] ; , , or ) was the Vietnam War mass killing of between 347 and 504 unarmed civilians in South Vietnam on March 16, 1968. <P0-S1>  It was committed by U.S. Army soldiers from Company C, 1st Battalion, 20th Infantry Regiment, 11th Brigade, 23rd (Americal) Infantry Division. <P0-S2>  Victims included men, women, children, and infants. <P0-S3>  Some of the women were gang-raped and their bodies mutilated. <P0-S4>  Twenty-six soldiers were charged with criminal offenses, but only Lieutenant William Calley Jr., a platoon leader in C Company, was convicted. <P0-S5>  Found guilty of killing 22 villagers, he was originally given a life sentence, but served only three and a half years under house arrest. <SEP> <P1-S0> David Francis Bieber (born 3 February 1966) also known under the alias Nathan Wayne Coleman is an American convicted murderer. <P1-S1>  A fugitive from the United States, he murdered PC Ian Broadhurst and attempted to murder PCs Neil Roper and James Banks on 26 December 2003 in Leeds, England, sparking a nationwide search before he was captured. <P1-S2>  He was given a whole life sentence after being found guilty of murder in December 2004 and the trial judge recommended that he should never be released, however, in 2008 this sentence was controversially reduced to a minimum term of 37 years by the court of appeal, after which he could apply for parole. <SEP> <P2-S0> Ghazala Khan (29 October 1986 – 23 September 2005) was a Danish woman, who was shot and killed in Denmark by her brother after she had married against the will of the family. <P2-S1>  The murder of Ghazala had been ordered by her father to save the family honour, making it a so‐called honour killing. <P2-S2>  No fewer than nine people from her family took part in arranging and performing the murder and they were all found guilty by "Østre Landsret" (the High Court of Eastern Denmark) on 27 June 2006 on counts of manslaughter and attempted manslaughter (of her husband). <P2-S3>  This was a ruling of historic importance, the first time in western Europe that such a large number of family members were found guilty in an "honour killing" case. <P2-S4>  It is expected that the conviction will serve as precedent throughout Europe for future similar cases and that the sentences will send a strong signal and have a noticeable deterrent effect. <P2-S5>  Manu Sareen, a youth worker helping girls facing arranged marriages said: "It will have a preventive effect. <P2-S6>  Some families may abandon similar plans because of today's ruling." <SEP> <P3-S0> William Laws Calley Jr. (born June 8, 1943) is a former United States Army officer convicted by court-martial of murdering 22 unarmed South Vietnamese civilians in the My Lai Massacre on March 16, 1968, during the Vietnam War. <P3-S1>  While not technically exonerated, after three and a half years of house arrest, Calley was released after a ruling by federal judge J. Robert Elliott who found that Calley's trial had been prejudiced by pre-trial publicity, denial of subpoenas of certain defense witnesses, refusal of the United States House of Representatives to release testimony taken in executive session of its My Lai investigation, and inadequate notice of the charges. <P3-S2>  His initial conviction faced widespread public opposition both due to the campaign circumstances of civilian embedded Viet Cong, and due to Calley being singled out as the sole convicted officer in relation to the massacre.
