Well, his phone number checks out, so at least it wasn't some fake number.

Ouch, man! Too bad.

I bet, though, if this number checked out, you are going to be OK with respect to tracking this down and not taking a hit on it. By "city" tow truck, I assume that would be one operated by the city, not a brand name? I guess it is *possible* that they didn't know they hit, but hard to imagine.

During my last week of unemployment I watched a huge dump truck towing a flatbed trailer take an acute left hand turn. The trailer pivoted and the rear edge (tapered for equipment to drive on) sliced through this poor lady's A pillar. We weren't sure the truck driver even noticed. Oh, yeah, I'm an official witness :-( Oh, and we found the truck -- hadn't gone too far.
