This is Tosha's sister and I wanted to clear something up for all of you that was a huge mystery for us as well. The 11:30pm ping in Lavonia actually happened at 7:30 PM EST. The 11:30pm was another time zone and we didn't figure that out until several days later. So her phone pinged in Lavonia in 7:30PM and then when we got the detailed phone records and there were two more pings in Demorest GA around 8:50PM which confirmed to us which route she took from Lavonia to Blue Ridge and we followed that at night with a spot light and that's how we found her car.
Please see her FB page below to follow the details that I update regularly. I have also posted a full story with a detailed timeline of the situation.
Please keep praying and sharing.
