From what I've read, and for what it's worth. Scott and the tracker, along with 2 dogs [?], separated at the bakkie. The tracker returned and, apparently when Scott didn't show up, alerted others that Scott was missing [How? Radio?]. All the dogs returned 'to the camp' [how far was the camp to the bakkie? to the packs? who long did it take Scott's dog to return after Scott was last seen?]. If Scott had only one dog with him, was there a leash?
Scott's rifle and personal items were reportedly in the bakkie. This, from a distance, seems odd because an unattended vehicle--with rifle--would be a temptation for thieves. If true, however, it suggests that Scott and/or the tracker intended to return to the bakkie soon. Was the GPS in the bakkie or in one of the packs?
Scott's packs were found on the Zim bank of the Limpopo. How far were his packs from the bakkie?
What is the condition of the Limpopo River where the packs were found? Is it high? Currents? Is it shallow enough to wade? Is there some kind of ford?
Any theories as to why Scott might--maybe--have entered the River? Did he intend to cross it? Why might he want to cross it? Any evidence that one or more dogs may have crossed the river and Scott followed them? could he have been scouting the river for future croc/hippo hunts? could he have been checking for leopard tracks in the river mud? The croc info that we are receiving may or may not be significant. It shouldn't take long to obtain results.
