This body was found in my old neighborhood, less than a mile from my old apartment. My bets, looking at NAMUS alone and based on just location:
Russell Keener, missing 9/11/11, missing from that zip code, if it's been long enough for the decomposition
Kelsey Collins, missing 5/9/09, since I can see this being a route to the park and ride terminal 128th/Airport
But then again, it's only a few miles off the freeway (I-5) so anything is possible. It's right up against a little airport (no commercial flights) and as with most of Everett, has lots of alder trees and lots of scrubby brush. While traffic would flow through this area, there isn't much there except a few coffee stands. To the north, in apartments a mile or so north of where I lived (maybe 3 miles away), there is heavy drug activity.
Sigh...hate that they keep finding them, this one isn't very far from where they found Snohomish County Jane Doe.
