Investigations into Marokopa fugitive Tom Phillips are far from over, after he was shot dead by police yesterday.

The manhunt for Phillips and his three children stretched across four years.

One of his children was with him at the scene, and the other two were found last night at a campsite in dense bush about two kilometres away.

Police Commissioner Richard Chambers says they're investigating possible accomplices in this case.

"We're going to put a puzzle together, we're going to better understand the last four years - anybody who may have been helping him, supplying him with something."
