So, two reasons FD could have been out on Silver Spring Rd on 6/25: either to look for a remote, cell-free spot to cut off his ankle monitor; or, to revisit the scene where he had been on may 24th. (I note the interesting timing, that this trip of his was the day they announced the search at MIRA had ended with nothing found).
Some of you have said here that murderers can't avoid revisiting the scene; he would have to be super stupid to revisit the scene when he was tracked by GPS, you think he would have learned from the Albany Ave mistake. So maybe this was to mislead. Nonetheless...
On the latter point, originally I timed it out using Google map and found it did not fit with the 47 minute time frame between Welles-Waveny-Merritt NC rest area, and found going out to Silver Spring Rd was at least 10 minutes longer than available time.
However, I made a misjudgment there and had him going RT from Waveny out to Silver Spring, and when I went back and re-did the route getting on the Merritt on the way back instead, it came up with 39 minutes RT. Add that to Welles-Waveny in 10 minutes, and it is very close to the elapsed time in AW2 between Welles-NB 15 NC rest stop (47 minutes). Especially if the neighbor webcam timer on Welles is off by a minute or two from the rest stop timer. So it's possible that he went out there after the body transfer on Lapham on the 24th.
The route I used on Google maps started at the parking lot inside Waveny Park (I could not get it set exactly on the Lapham Rd pullout, this is actually a bit further than the Lapham pullout so could account for 1-2 minute added time, making it even closer in time), then to an address on corner of Wilton Rd (exact address withheld for privacy, used for convenience only), South Salem NY, which is on the corner of Silver Spring and Wilton Rd/Vista Rd and a good spot for where the remote, no-houses section of Silver Spring/Laurel begins; then exactly to the NB 15 Mobil/Dunkin service station at NC. Total time it gives me is 39 minutes for that trip.
While parts of this road are bumpy, unpaved, the speed limit is 25 but you can speed at least 10-15mph over back there on the straight sections if you don't mind it too bumpy. He would be in the truck, so no problem. And no chance getting caught speeding back there, it's very remote almost like a private road. IMO.
This would mean that everything had to happen quickly, the body transfer at Lapham, the dump on Silver Spring, and back to the Merritt. He wouldn't even necessarily need to get all the way to East St where it crosses directly over the reservoir (plus the water level might have been too low then, not sure) because there are plenty of remote woods to put a body there before that. Certainly nobody would associate this area with FD in any way. Very wooded so home webcams not likely to catch cars on the road.
Someone who is local might want to go out there and see if starting at Lapham how far you can get up Silver Spring in 17-20 minutes, if you can get to the section past Wilton Rd/Vista Rd (Wilton Rd on NY side, Vista Rd on Wilton side). Use a truck or 4WD so you can speed on the bumpy part
Of course, if there is substantial blood in 80MS, that would mean the body was brought up there. I lean towards that being the case, but this scenario could be another option to account for the time gap after leaving Welles that morning.
MOO.
