Australian police have made a trans-Tasman appeal for information over a final confession from an Australian navy sailor that he killed three people.
Richard Edward Dorrough confessed to killing three people in a note left when he committed suicide in Perth last year,
He had been acquitted of the 1998 murder of Rachael Campbell in Sydney, and in 1997 he was the last person known to have seen Sara-Lee Davey in Broome.
Police have asked for help tracking his movements around Australia and New Zealand.
He was reportedly living in Auckland between May and August 2006.

Assistant commissioner Michelle Fyfe said people who knew Mr Dorrough, or who might recognise him, may hold the key to solving unsolved crimes.
She said someone somewhere may have crucial information.
"There is information out there that we don't hold whether that be here in Western Australia, whether that be on the eastern seaboard or in New Zealand," she said.
"There are members of the public who knew Mr Dorrough, who associated with him, who may very well recognise him and they may hold the key to us solving an unsolved crime."
Dorrough was a crew member of the patrol boat HMAS Geelong and spent time in different locations around Australia.
