Question: At what facility did a prison riot occur in response to the death of the man charged with the murder of John Vincent Mills?

The Attica Prison riot, also known as the Attica Prison rebellion or Attica Prison uprising, occurred at the Attica Correctional Facility in Attica, New York, United States in 1971.  Based upon prisoners' demands for better living conditions and political rights, the riot was one of the most well-known and significant uprisings of the Prisoners' Rights Movement.  On September 9, 1971, two weeks after the killing of George Jackson at San Quentin State Prison, about 1,000 of the Attica prison's approximately 2,200 inmates rioted and took control of the prison, taking 42 staff hostage. <SEP> The Vancouver Island Regional Correctional Centre (VIRCC) is a Regional Correctional Centre that is located in the District Municipality of Saanich, Vancouver Island, British Columbia, Canada.  It lies within metropolitan Victoria, British Columbia, in its northwest suburbs.  The centre offers grief counseling to the family members of prisoners' deceased victims.  On October 26, 1977, approximately 20 inmates took a prison officer hostage with a knife, but released him peacefully the next day.  A prison riot at Prince George Regional Correctional Centre on April 26, 1983 led to ten prisoners being transferred to VIRCC.  A prison riot at VIRCC in January 1985 led to 37 prisoners appearing before a disciplinary review board.  On March 26, 2005, five inmates were charged with mischief after having together caused between $40,000 and $50,000 worth of damage to a living unit at the centre.  In September 2006, David Johnston, a homeless man imprisoned at the VIRCC due to repeated sleeping on Beacon Hill Park and St. Ann's Academy property, went on a hunger strike to fight for the right to sleep outdoors and was supported by other homeless people who created a tent city.  On February 22, 2007, inmate Wayne Allan Turner was found dead in the centre, hanging from a fire sprinkler head.  British Columbia Government and Service Employees' Union sheriff services component chairman Dean Purdy stated in March 2010 that there had been 63 assaults on the centre's guards by inmates since 2003 when the jail became overcrowded due to the closing of nine other British Columbia jails.  An attempted prison escape by two prisoners was foiled in July 2011. <SEP> The Soledad Brothers were three African-American inmates charged with the murder of a white prison guard, John Vincent Mills, at California's Soledad Prison on January 16, 1970.  George Jackson, Fleeta Drumgo, and John Clutchette were said to have murdered Mills in retaliation for the shooting deaths of three black prisoners during a prison fight in the exercise yard three days prior by another guard, Opie G. Miller. <SEP>  In 1970, he was charged, along with two other Soledad Brothers, with the murder of prison guard John Vincent Mills in the aftermath of a prison fight. George Lester Jackson (September 23, 1941 – August 21, 1971) was an African-American activist and author.  While serving a sentence for armed robbery in 1961, Jackson became involved in revolutionary activity and co-founded the Maoist-Marxist Black Guerrilla Family.  The same year, he published "Soledad Brother: The Prison Letters of George Jackson", a combination of autobiography and manifesto addressed to a black American audience.  The book would become a best-seller and earn Jackson personal fame.  In 1971, Jackson took several guards and two inmates hostage in a bid to escape from San Quentin Prison.  However, the incident ended with Jackson being shot and killed by a guard, in addition to the deaths of 5 hostages.
