6 is on the north border of DC.
Connect 7 & 8. The line lies along the east border of DC
How close to #6 is Brentwood??
It's hard to find a pattern except they certainly appear to have a center to the first five...which were all kills.
I consider the window shot just a ploy to see who would show up (two cops and not a fleet).

6 is near the northernmost point of DC, Brentwood is closer to the eastern point than the top.
