Detectives have confirmed skeletal remains found in the Royal National Park are those of a Woronora man, who had been missing for four years.
Stuart Dohrn was 43 years old when he was last seen at his Woronora home on Monday, December 14, 2015.
He had taken out $130 and packed camping supplies, including a tent before he left, but left his wallet and phone at home.
Family members reported Mr Dohrn missing to officers from police that evening.
However, while extensive inquiries were made, Mr Dohrn was not seen alive again.
Several appeals for help from the public were made through the Leader, including during the annual Missing Person's Week, in the years following Mr Dohrn's disappearance
A police spokesman said on Monday bushwalkers alerted police after they discovered human skeletal remains south of Audley Weir on Sunday, June 2 this year.
"The remains were taken for forensic examination, and investigators have now been advised that they have been confirmed as those of the missing man," the spokesman said.
"Police have kept Mr Dohrn's family apprised of the developments.
"Inquiries are continuing."
