Borce claims to have gone on his drive from 10ish to 12pm.
The cctv footage of Merc captured at the diggers crossing is at 11:15am thereabouts .
So he was still heading out to toolern vale then gisborne/Macedon . If body was buried on that trip, he still had the drive to Macedon (30km approx 20 min drive approx), followed by looking for a suitable burial spot, taking her body there, return home direct not via coburg (approx 50km, 40min drive). Coming home via coburg would add an extra 40 minutes at least to the journey.
That's a quick turn around to have completed all that, not even taking into account that he may have wanted to clean the car, dispose of items elsewhere.
If Coburg is of no significance as in not related to stopping off at TAB joints or visiting people, do you think he could have travelled to coburg to use one of the car wash places just off the freeway on bell street coburg.
Wonder if police could tell if Karen's car was squeaky clean on the outside which would indicate a very recent clean .
