I believe she took a Greyhound and went to NC in spite of what Hubby said. That's my opinion. I also believe she had more money than he thought she had. Maybe he gave her $200 to spend in Philly but she had more of her own. jmho..........
She might have used her old license to get the car....that might be the license she went back to get.
She rented a car in NC and pre-scheduled the auto rental co to pick up the car. They picked it up as scheduled and never noticed she was missing. Just thought she kept the keys.
LE looked for her under her married name (Smith) not her previous name and they missed it.
She went for a hike, was planning to spend the day in the mountains and she was murdered. She might have met up with a rapist/killer in the mountains or saw something she shouldn't have seen and was murdered because of it.
Mountain people don't want strangers getting into their business. They still have moonshine, pot growing, illegal hunting, and people hiding from the law. She might have run into the wrong person or seen something she shouldn't have seen.
Interesting! I wonder if LE checked to see if she used her maiden or previous married name to rent a car, etc. She did have separate accounts from her husband. Although, she was married to Jeff for 10 years, which means a license from her old life, with another name, would have been very old and expired. Maybe I'm wrong that she was married to him for 10 years? I'll have to look into that.
