Derek Chauvin, the former Minneapolis police officer convicted of murdering George Floyd, was stabbed 22 times in the law library at the Federal Correctional Institution in Tucson, AZ, with an improvised knife, federal prosecutors said.

52-year-old John Turscak was charged with attempted murder in the prison stabbing. He later told FBI agents that he’d been thinking about assaulting Chauvin for about a month because he is a high-profile inmate but denied wanting to kill him, prosecutors said.
