Google Maps

Here's a Google Map to the apartment where Johnia was killed.

And here's the distance from the apartment to the Weigel's convenience store where Johnia's roommate ran when he fled the apartment. Google gives the distance as 0.7 miles sticking to the roads, but I've clocked the realistic distance starting from Warren House (where he tried to get someone, anyone to call police) and it's between four and five tenths of a mile.
