Tragic, but I did notice that you didn't answer my question.
You assumed the driver in your story was Mexican (and insinuated he was illegal) based on a ~maybe~ 1/10th second glance at his face.
Ratty old Honda with a Mexican flag decal. I saw the driver clearly for as I pulled onto the shoulder and stopped. We get hundreds of such old cars abandoned on roadsides and private property each year in our county along with all the other basura.
It really annoys our prosperous and legal immigrant neighbors (and friends).
