Btw, why didn't Shannan wait for the police to arrive when she asked the neighbor for help? what made her decide to run off again into the darkness and why didn't she bother to hide in the neighbor's house instead? i'm also curious why, if Shannan had been a victim of the LISK, he chose to dump her body in the marsh rather than his usual dumping ground?
This is why I lean towards the drugs/ bipolar having a lot to do with her reactions. She didn't trust anyone and I would think the 911 operator would have told her to go to a neighbors house.
Its really the only answer I can think of for why she would:
Say people are trying to kill her
Run from her driver
Run from neighbors
Not sit tight and hide
Possibly run into a marsh
