(Minneapolis, MN)  —  The judge in the Derek Chauvin trial also signed the no-knock warrant that resulted in the shooting death of Amir Locke.  The content of the warrants and underlying affidavits connected to a January St. Paul murder case are sealed, but published reports say Locke was not the subject of the warrant.  Hennepin County Courts spokesperson Matt Lehman says the Minnesota Code of Judicial Conduct prohibits Judge Cahill from commenting on any warrant he signs.  Locke was shot and killed last week when police involved in the raid say he pointed a gun at them and refused commands to get on the floor.
