snipped by me
I would think that someone thinking of committing suicide would have a much easier time picking a good "hiding" spot than someone who was trying to hide a body. If she did herself harm, she could have driven anywhere, down any road or trail, to the water, etc. If a police officer or anyone else stopped her to question, she could say she was lost, thought her car was having trouble, etc. Someone with a body on their hands to dispose of would want it gone as fast as possible. If they were to be stopped by anyone, they could be found out.
As I pointed out to someone else, just this morning, the perfect hiding places are usually right out in the open. Does anyone remember about 20 years ago, a lady over in Villanow, GA going missing. They searched for her for days and found nothing. She was finally found just down the street from her home, propped up against a tree. Right out in plain sight, on a fairly well travelled road. No one noticed because it was normal. She looked like she was sitting there enjoying a summer afternoon, or reading a book. If you happened to glance at her, it didn't strike you as unnatural.
So, that's my thoughts for this morning.
