What is strange about the case is where she was found vs. where she was last seen. Last seen off of Rt. 1 in Fairfax/Alexandria which was / and still is a very busy & populated area.
She was found off Rt. 50 in between South Riding and Aldie (Loudoun County), which is a 40 min. drive West into (at the time) the middle of nowhere. She was found 1/4 mile East of Gilbert's Corner which is a crossing point for rt. 50 and rt. 15. This leads me to believe the killer could either be (a). local from northern Prince William Co. (b) southern Loudoun County, or (c) Western Fairfax County.
In 1982, this part of Loudoun County was very rural, it's hard for me to believe someone would take her out there if they didn't know the area...
The lack of information available about this case is really frustrating, but I think I have some ideas. None of this is confirmed, but it's just me putting pieces together. I agree 100% about how strange the location she was found is. It really doesn't make a lot of sense that you would end up there if you didn't intend to or need to.
Hopefully all of the following makes sense. Reading it back it sounds very convoluted, so I apologize.
I've been doing some research into the whole scene of Route 1/Richmond Highway in the 60s, 70s, early 80s. Based on what I've found, it's entirely possible that the person/people who did this could have even been from as far as Winchester. I say this because apparently the Fancy Dancer (which was only its name for a little whiles) was one of a few bars/strip clubs on Route 1 that people from Winchester would come to, according to some forums and facebook group posts. I have a hunch for why this is but I'm still looking into it. I think the most likely scenario is that the person responsible wasn't from Fairfax County. Anywhere farther west is more plausible in my opinion.
It's possible that the person could have left her body on the way home, as Route 50 will take you all the way to Winchester, or maybe the person needed to get off at 15 in either direction (maybe to get to Leesburg or Purcellville), so they left her at the last possible place before the intersection. 50 is by no means the most direct route to get really anywhere west, nor was it in 1982, but if you were 1. drinking and driving home wanting to avoid police and/or 2. needed to dispose of a body, you wouldn't take the route most traveled.
So thinking how they could have gotten from the Fancy Dancer to Gilbert's Corner... I am fairly sure that Veronica graduated from Robinson, so she would have lived in Fairfax, probably lived somewhere around the Braddock Rd area. If you think about how you would drive from Route 1 to Fairfax (say you agreed to drive her home on your way home but did not actually intend to), it would most likely be to get on 495, then off at Braddock Rd. It would be easy to just keep driving past that exit and get off at 50, or to take the Braddock Rd exit and then just not stop at her house. You would then be driving through what is now still a largely residential area that is very quiet at 1:30 - 2:00 am. In 1982, it was considerably less built up, so I imagine it was just as quiet, if not more. You can get to 50 fairly easily from Braddock Rd (based on 1981 maps). The intersection with 15 is then anywhere from 10-25 miles down 50 (depending on where you got on the road), and as we know, this is where she was found a few hours later. After leaving her body, it would be really simple to just carry on home whichever direction you needed to go.
Obviously there is no information about cause of death or if there was any signs of sexual assault (other than the fact that she was found partially clothed), but the person still would have needed to stop somewhere for some amount of time to commit the murder. That entire area between Braddock Road and Gilbert's Corner had and still has so many options for somewhere to pull over and do this without anyone seeing. It's dark, residential, and the farther west, it's even more rural. That's another reason you might choose Route 50 over the more obvious options.
Also, if this person was a friend (or her ex boyfriend), they could already know the area from maybe driving her or others home before this.
