Thao was recorded watching as Chauvin continued to press on Floyd’s neck with his knee. Kueng was one of the first officers on the scene and helped pin Floyd down. Lane was detailed in earlier charges as pointing a gun at Floyd before handcuffing, and later asked whether officers should roll Floyd on his side as he was restrained.
CNN reports two autopsies on Floyd determined that he died by homicide. Minneapolis Police chief Medaria Arradondo fired the four officers and said they were "complicit" in Floyd's death, and Floyd's family and protesters nationwide have called for them to be arrested and convicted for the killing.
