Jury now being taken, by SA Police crime scene investigator, through photos of campsite, tyre tracks and evidence taken from
#SaltCreek.
Jury told police can determine path a vehicle takes through sand dunes, which direction it went & if it went "back and forth".
Tracking 4WD's path was "a matter of following the tracks through hundreds and hundreds of metres of sand dunes".
Jury hears investigators found blood spatter and staining at numerous places on accused's 4WD.
Analysis showed blood on bullbar had "projected" there "from right to left, and from front toward rear of vehicle".
DPP: "When you say 'projected', does that mean there was blood flying through the air from a source?"
Investigator says two types of spatter are passive and projected. Passive drips down using gravity, projected "requires force".
Investigator says the blood found on the bullbar was "projected there, by some force, from a source".
Investigators found passive blood spatter on the 4WD's rear passenger door and window - "in excess of 100 stains".
Passive spatter has been "diluted & flows, or when the volume of blood is so great that it overcomes gravity & flows in a line".
Another stain, measuring 10cm by 5cm, "transferred" from a bleeding object to the bullbar of the 4WD.
Investigator says there was blood on almost all sides of car, plus roof and bullbar. Would later also find a thread on its undercarriage.
