Transients definitely by the river. It was beautiful out that night, but chilly. So yes it is very possible transients starting the dumpster fire by the river if that is where you were going. Not so much at townhouses, but not impossible.
That's where I was going, In da Middle- thank you. (I love locals!)
I don't particularly like to type this, but it's surprising how many transient/homeless persons find bodies in dumpsters. Is there a homeless 'community' by the river (or anywhere along the route(s) of travel possibly taken by someone leaving the residence in a vehicle?)
TIA.
