A former gang member and FBI informant was charged on Friday with attempted murder over the stabbing last week of ex-police officer Derek Chauvin at a federal prison in Arizona.

John Turscak stabbed Chauvin 22 times at the Federal Correctional Institution in Tucson and said he would have killed Chauvin had officers not responded so quickly, federal prosecutors said.
