Police determined that Biden’s first wife drove into the path of Dunn’s tractor-trailer, possibly because her head was turned and she didn’t see the oncoming truck.
Dunn, who overturned his rig while swerving to avoid a collision, ran to the wrecked car and was the first to render assistance.
Police filed no charges against Dunn, who at that time lived in North East, Md. with his wife, Ruby, and their seven children.
