It seems as if it could be the stalker person.
They probably live near there.
Jayme and her mom live close by each other,
on the same road.
If it is a stalker situation, he/she would know
Jayme's car and her routine.
It would not be too hard to do a forensic evaluation
of Jayme's computer and find her cell phone records.
I wonder how long it takes to track the stalker on a computer? I think I'll ask . I mean, what if it is the stalker and he has her alive somewhere? They need to find her FAST!!!
