Derek Chauvin was charged with second-degree murder, third-degree
murder and second-degree manslaughter — all of which required the jury
to conclude that his actions were a “substantial causal factor” in
Floyd’s death and that his use of force was unreasonable.

Floyd died last May after Chauvin, a 45-year-old now-fired white
officer, pinned his knee on the 46-year-old Black man’s neck for about 9
½ minutes.
