I would love to know what her cell phone data pings were doing between February 3-5, If her phone was off that would be very telling, especially if her old phone records have no history of being randomly off at times. She's social media savvy people like that have their phones on 24/7,
If her phone was indeed on and but not anywhere near florida that is also very interesting, she may have left it on in a specific location while she was away driving, however if its on and on the move and still not anywhere near florida that's even more interesting.
The police no doubt already know this data, i would love to know what it say's right now.
