That's a tight timeline to drive, probably impossible without a co-driver. Google maps have Alice Springs to Adelaide as 16 hours driving (no breaks). Consider the police have said Khandalyce was in the car when it was stopped in Cooper Pedy on the 8th.
3/11 Pt Augusta
6/11 Adelaide (16hrs driving)
8/11 Pulled over in Cooper Pedy (9 hrs driving)
9/11 Alice Springs (7 hrs driving)
14/11 Adelaide (16 hrs driving)
Insert somewhere in here also the meeting with the friend at Marion Shopping Centre - no wonder she looked tired)
17/11 Mt Gambier (4 hrs) Interesting that both a suitcase shop (Strandbags) and photo shop are located here. Was Karlie dead already or was it planned she would be..... although there is an unconfirmed sighting of her in Canberra....
Such a busy time for her. Was Khandalyce with her the whole time....
