Laride Conerly said that he was headed eastbound on Highway 175 when he saw a silver Infiniti going down the service road with no lights on. At some point, that car lost control on an on-ramp, cut through a grassy area, struck a guardrail and spun into the street.

Conerly said that he and several others pulled over to help the male driver. He said that the Good Samaritan had gotten the man out of the car, walked him to the side of the road and was placing a call to 911 when an oncoming Ford F-150 hit her.

Calling Ware a hero, Conerly said, “She went over, above and beyond to help that individual. She even stopped when… what’s so touching about her brave, heroic effort is that she stopped to make sure that he was okay and make sure that he got some help. And to see her laying in the street is just heartbreaking.”

Though he did not know the Good Samaritan who was killed, Conerly had a message for those who did. “If I could say anything to her family… I wish you could have seen how heroic her efforts were to try and help this guy, stop him and stop traffic to make sure he was safe and nobody else got hurt.”
