I think that I figured out the general area where she was found by using the information off of the AA County Cold Case website and Google Maps. I am going to now do a Mapquest with a few of his past addresses to see if those were within walking distance.
I figured that she was in a rush to get to the Mall before it closed. She left at 8:30 p.m., and the Mall probably closed at 9 p.m. I don't know the location of Thom McCann's, but it may have had a side entrance (to the Mall) that she could have used to run in to get the shoe dye. She did in fact buy the dye according to a store clerk.
If she used a secluded, side entrance (if there was one), this could have been one of those unfortunate things where she was quickly forced into her car when nobody else was around and made to drive down to the Pasadena area, which he knew very well since he lived in that area and had gone to school in that area.
I believe that he made her drive there (or he could have knocked her out and driven the car down there himself like the Kelsey Smith/Edwin Hall case). He then raped and strangled her, drove her car to the wooded median and dumped her and abandoned the car.
I believe that her purse, keys and underwear were not found. I do believe that there are others who know some information. I think that he had at least infant at the time of this murder. I don't know if he was with the mother or not. If he was, I wonder what she knows. I hope that she has been forthcoming. I imagine, now that they have a name, the police have talked to relatives and friends. I am still amazed at how genealogy mapping can assist in solving these old cases.
It seems that FCW remained in Maryland at least until the 1990's as I found where he had a citation for fishing without a license. You can check here: https://casesearch.courts.state.md.us/casesearch/processDisclaimer.jis?disclaimer=Y

Here's another good resource for old aerial photos to use on cold cases. The photos will still have a watermark on them, but they're sometimes helpful.
