Imunek Williams is a hero. According to People , the pregnant school bus driver evacuated students on her bus just a moment before it set on fire in Milwaukee on Wednesday. Williams was around two hours into her regular route when she noticed a strange smell and smoke coming from her bus. She pulled over and got the 37 students that she was taking to school — who ranged in age from kindergarten to high school — out of the vehicle, WISN-TV reported.
