Elderly woman feared killed by crocodile in Australia

There are fears that an elderly woman has been killed by a crocodile in far north Queensland, Australia.

A search and rescue team has found clothing, a walking stick, and "biological matter" suspected to be human remains near a crocodile-infested creek in Port Douglas, north of Cairns.

The walking stick belongs to Anne Cameron, 79, who went missing three days ago from the Ozcare aged care facility in Port Douglas.

Far North police acting inspector Ed Lukin said "Because of the proximity of these items and this unknown material located by this creek bank we cannot rule out a croc attack."

Forensic testing is being carried out on the remains to determine if they are human.

The remains were found near the Mowbray River where three large crocodiles are regularly spotted by locals, according to the Cairns Post.

Ms Cameron suffers from dementia, and was last seen walking on the grounds of the aged care facility on Tuesday afternoon.
