The Route 15 goes right past there.
Also, if he took the Route 15 after the Pharmacy, it goes right past the DoubleTree and the courts. Perhaps he got off a bus at the wrong place, not walked to the wrong place.
Cabbie said when he got there...20 minutes later, John was not there...
I looked at a map...A little confusing...There is a 9th Street and 273 and a Route 9 and 273...Without a second reference...who knows what happened...
