Donald Williams, who witnessed former Minneapolis police officer Derek Chauvin kneeling on George Floyd last May, testified at Chauvin's trial Tuesday that he called 911 on the officers at the scene because he believed he "witnessed a murder."
The big picture: Williams took the stand for the second day in the nationally televised trial as prosecutors seek to win a conviction against Chauvin on murder and manslaughter charges.
On Monday, Minneapolis 911 dispatcher Jena Scurry testified that she felt a "gut instinct" that "something was not right" as she watched officers pin Floyd to the ground.
What they're saying: Williams, a trained mixed martial arts fighter, called Chauvin's hold on Floyd a "blood choke" during his testimony on Monday.
On Tuesday, he testified that felt the need to call 911 instead of speaking to the officers directly because "we just didn't have no connection. I spoke to them, but not on a connection of a human being relationship."
In his call to the 911 operator, which was played at the trial, an audibly agitated Williams said that Chauvin was "trying to kill a guy that wasn't resisting arrest."
