A former police negotiator says police must've found something obvious at Tom Phillips' campsites that indicates he was getting outside help.
The Marokopa fugitive was shot dead by police on Monday, and his children are now in state care.
A second campsite in dense bush has been uncovered - about 200 metres from the first.
Lance Burdett says police are fairly sure Phillips was getting outside help, so items from the campsites will be used as evidence.
"It's fingerprinted, it's photographed, it's everything that they can do to find out - DNA testing on every item, to track down who may have been involved."
