Thanks for your comments to me, Kickoff and Roses. Very much appreciated. I'm really glad to be part of this forum.
As for my mention of accelerant, taser, etc. I was trying throw out some ideas. If he's on that path, he's got to silence her quickly and gain control over her. What's the fastest, easiest way to do that?
For the burn marks on the pics posted - do they looked directed or like something that was part of an actual fire? Did he mean to burn the entire body and ran out of time? Or direct the burning at specific parts (face, hands, feet)? Were the clothes burned - I can't recall. The idea that he wanted to burn the entire body seems unlikely - way too much flame and smoke would result. So he's trying to destroy DNA on the face and hands but why the feet? Is there another reason?
One thing about fire - to start any type of fire would probably require more than a lighter. So he planned it. And he left her nude. That speaks of hatred and rage, maybe toward her but maybe toward what she stood for. A young, beautiful, educated, single, successful woman who lived in an exciting city.
I do think it would be easy to cut through those woods from the cemetery to the path. It's heavily wooded, a simple matter to stay out of sight of the road and the houses. Maybe there is even a place at the cemetery where a car could be parked out of sight. Again, this could be wrong. There are lots of ways it could have happened.
