Mystery Road: Origin
Mystery Road: Origin is the 3rd series in the popular Australian crime series.
Series 3 is directed by Dylan River and is a prequel to first 2 Mystery Road series with Mark Coles Smith playing a young version of Jay Swan (played by Care Experienced actor Aaron Pederson in the 1st 2 series).
It's not clear, but it seems that the 16-year-old boy whose Jack, was orphaned at the age of 12. He then ran away from the mission where he'd been living and was independent from then on.
At the end of the series, a little girl is in the kinship care of her aunt because her parents have been imprisoned.
It's not clear, but it seems that the 16 year old boy who was murdered 8 years previously may also have been in foster or kinship care.
