I'm going to swap computers so I can post a link between the two addresss for you, MSpy! bear with me.
Like you, I have been thinking about the possibility of him following them from the nightclub. To my mind, that could make all the difference in the case.
If he did NOT follow them, he is just a predatory killer, stalking known hang outs where he knows he will find courting couples. Or, in the case of the rape survivor, a woman and maybe her boyfriend ( he was a pilot, away a lot).
If he DID follow them, he is still a predatory stalker, but he is one who hangs out in clubs, looking for victims. So then, the fact that the rape survivor and Cheryl both worked in striptease clubs, might be very relevant.
ETA: In the first case, he would have to be a local. In the second, he could be a stranger just following people.

I don't think this was a coincidence (their occupations). There is a 24 minute drive from Cheryl's murder site to the rape survivor's house. I think he targeted them and had watched them from afar. Seems that way to me at this point. Do you know if Cheryl lived at home with parents or with roommates? Maybe it was hard for this guy to get her in her home, so he saw an opportunity to get her at the lover's lane. Just speculating.
