Nichols, 29, arrived at a hospital in critical condition after several officers punched and kicked him and hit him with a baton, and died three days later from his injuries.
EMTs Robert Long and JaMichael Sandridge "failed to conduct an adequate patient assessment" upon seeing the injured Nichols a few minutes after police had stopped beating him, Fire Chief Gina Sweat said in a statement.
Michelle Whitaker, a lieutenant in the fire department, drove them to the scene and remained in the vehicle after arriving. She was also terminated for violating department policy, the statement said.
