One article has a photo of a male, apparently Hispanic, and identifies him as Jonathan's coworker and "Witness #1," who says Jonathan was going to exchange insurance information. Another article mentions his girlfriend and says she found out about Jonathan's death by 'social media.'
I think they're two different people and I don't think the girlfriend was at the scene of the shooting.
You can pull over and wait for the cops too. The other driver in approaching her car wasn't just waiting ~ probably anxious to get to work, and now this.... be quite interesting to see what the cell phone records show ~ not that they're out there duking it out in road rage while on the phone but stuff happens doesn't it.
