@sister7 thats a good question, and frustratingly not one i can find an answer for; I wonder if the location of Ryan's house was hidden to protect potential roommates or maybe to not have people show up unnecessarily?
All I can say is that his place was a 15-20 minute walk from Burfield Rd., where the party was. I don't believe it was towards the main village? As when a potential sighting was reported on Fairways Dr., which leads towards the heart of the village, this was
described as a new search area and one not covered in the initial search. That walking distance is estimated at 16 mins so the distance to his house should also span approx that same distance on the map.
That's where I'm confused, however, as there aren't a lot of residential areas within 20 mins that ARENT in this direction?? There are a number of accommodations that are accessible via Sun Peaks Rd on Sunburst Pl., but I don't think it would be that weird for him to take the route through Fairways drive and thus I won't think Fairways would have been reported as a new search area??
Now, if you were to walk the complete opposite direction, to the left in this image, there are a couple of buildings that are accessible by going back on Sun Peaks Rd., then taking Industrial Way (the road that goes upwards near the red dotted line). These buildings would be a ~17 min walk away, so would fit. Sadly, Google Satellite is not sharp enough to make anything out really, and Google street view never took their car that far, so I don't know if these are residential buildings, warehouses, storage, etc... I know that employee residences may be out of the way and not on the map, so I'm not discounting that there are employee apartments around here.
