John Turscak, a former gang member and one-time FBI informant, faces charges of attempted murder following a violent incident involving Derek Chauvin in an Arizona federal prison. Turscak, who is currently serving a 30-year sentence for crimes related to his involvement with the Mexican Mafia gang, reportedly attacked Chauvin with an improvised knife in the prison’s law library on November 24, the day after Thanksgiving.
Turscak is accused of stabbing Chauvin, the ex-police officer convicted of murdering George Floyd, 22 times. The severity of these actions has led to multiple charges against Turscak, including assault with intent to commit murder, assault with a dangerous weapon, and assault resulting in serious bodily injury. Each charge carries a potential sentence of up to 20 years in prison.
Chauvin, who is serving a 21-year federal sentence for violating Floyd’s civil rights and a 22½-year state sentence for second-degree murder, was transferred to the Federal Correctional Institution in Tucson from a maximum-security prison in Minnesota in August 2022.
Turscak’s criminal history includes leading a Mexican Mafia faction in Los Angeles during the late 1990s and cooperating with the FBI as an informant in 1997. However, his relationship with the FBI ended when it was discovered that he continued to engage in criminal activities, including drug trafficking, extortion, and organizing assaults. In 2001, Turscak pleaded guilty to racketeering and conspiring to kill a gang rival.
