This is all very bizarre. My curiosity got up on this for some reason, so I looked through the various threads with posts by "Justin Vinci" here, and "Traditionalist" over on the LW.
One thing I noticed was that the blanket in a photo from a "What bow is this" thread started by Justin Vinci [From: Utah] dated Oct. 21, 2013, is the same as the blanket/sheet in the background of a photo from Feb. 25, 2014, of the young man in the thread on the LW.
The photobucket link [
http://s768.photobucket.com/user/vincikids/library/?sort=3&page=1 ] in the "What bow is this" thread also has pics with the same blanket/sheet in the background. There are also some other things in the photobucket pics that may have curious contents in light of this bizarre situation involving Rick Wallace, justin vinci, Justin Vinci ["From: Utah"], etc. (i.e., a recurve (camo riser?) with quiver and what appear to be full-metal jacket arrows, a number of other trad bows (8), a compound, some aluminum arrows, a shooting glove? [different from the glove in the Youtube vid?]).
The shoe on the foot of the person in the pic in the "What bow is this" thread also appears to be a shoe most likely worn by a teenage person (not an adult neighbor) -- that is the most reasonable inference anyway. The shoes/laces also appear to match the "Vans" shoe in one of the photobucket pics.
This is all "head scratchin'" stuff. Not sure why I posted this, just couldn't help myself. Like others have concluded, it just doesn't seem like there is any "adult neighbor" involved here???
