Savannah's sister Kirsten Hale states via her page on FB, which is being used a her official missing page, that Savannah was last seen at the Chevron Gas Station on North Market Street. I've no idea if that's in a good, bad or indifferent area, but I've attached a map, and also some screenshots from Google earth below.
The gas station is almost on the northern limit of the city, so I'm not sure where he home is in relation to this.
If she was at a bar in the city centre, it doesn't look like the nearest gas station she could've gone to. This gas station looks a bit rural actually, although seems to be on a busy enough cross-road for traffic.
ILE have looked at any cameras from the gas station, but they reset every 4 days, so nothing was there, however the building next door caught footage and it shows her leaving the gas station in her car and heading north on North Market Street.
Her sister states her debit card hasn't been used since that time, and also her Google stopped tracking her location then on her phone too. Location services wasn't turned off, which possibly indicates that the phone itself was turned off.
Really though, 4am is too late for a young 22 years old lady to be out and about.
And if she left the bar at 04.00hrs and got gas at 06.00hrs, what was she doing for those missing 2 hours???
MOO.
