Very sad. I think you are correct about the cross walk. The article is written that you could infer that there was no light, no cross walk, it was dark, and she is in a wheel chair which means the field of vision from the car would have been more limited. Having said that....WTH and why didn’t the first person stop.

Very possible, given the dearth of info here. Heck, it could have been so “glancing” that they didn’t even know they hit her. Likewise with the other two cars. I’ve run over dead animals in the road at night and not stopped.
