Prosecutors charged a Minneapolis police officer accused of pressing his knee against George Floyd’s neck with a new more serious charge of second-degree murder on Wednesday, and for the first time leveled charges against three other officers at the scene, according to criminal complaints. The updated criminal complaint against Derek Chauvin says the officer’s actions were a “substantial causal factor” in Floyd’s death. “Officer Chauvin’s restraint of Mr. Floyd in this manner for a prolonged period was a substantial causal factor in Mr. Floyd losing consciousness, constituting substantial bodily harm, and Mr. Floyd’s death as well,” the criminal complaint said.
