I'm glad you brought up the subject of "awareness space". This is a concept that someone (Vail maybe) brought to my attention during this case. In a nutshell, it's defined as " a personal perimeter created by the paths taken to and from personal nodes. Personal Pathway: the route that an individual takes to and from typical locations of activity in his or her daily life." Applied to certain crimes, it's brilliant, imo. I've recently started to take a look back at some of the cases I've worked here on WS, with a particular eye for awareness space. And let me tell you, it can totally change the way you view suspects and evidence.
Looking at awareness space in AJ's case, for instance, I've made note of several key locations.
1. The Millard St. residence (where she was last seen by mother)
2. S Battlefield Blvd. (where clothing was found)
3. the home that was broken into (where her jacket was found/planted)
4. the pond in Carrsville, IOW
5. the s hampton county home where her remains were found
The first 3 are all in WH's awareness space. He had previous lived in the Millard St. home, and even after he moved out, was there frequently to change vehicles. He knew S Battlefield Blvd. because this is a common route to Dare County, NC., and he knew the home of Texty, because he had been there on at least one occasion prior to the break in, and passed this house on his way to and from Millard St.
And while #4 and #5 can't be specifically tied to a common route WH travelled , we do know that a white quality plumbing van was seen near the pond in Carrsville, and WH drove a white Quality Plumbing van. We know that AJ's remains were found at a house in Franklin, and WH was working in Franklin at the time of her disappearance.
So, in terms of "awareness space", I can't think of any other person close to Anjelica, except for Wesley Hadsell, who hits on all 5 locations.
