yeah he was there 20 min later, inexplicably.  For some sick fate chance moment, he was uncovered and just out there when I was stopped next to him in the opposite direction.  
no authorities on the scene at first.  i took a sidestreet around the clusterfck that traffic instantly became, and i never heard a siren til i was on the way back.  and even then, there was a minimal police presence.  They might have been stuck in the crowd - I only saw motorcycle cops when I drove past - perhaps they were able to scoot in while the cars could not.  I haven't caught today's update of it.  I have thought about it all day for the last day now, though.
