THE disappearance of Malcolm Leslie Briggs from Mullumbimby in 1972 is one of the oldest missing persons cases on the Northern Rivers.
Mr Briggs was born in Mullumbimby on August 23, 1938, and spent his youth in the town.
Richmond Local Area Command Investigations Manager Detective Sergeant Bernadette Ingram said Mr Briggs, a former MP, was believed to have resided at Tenterfield and Drake before he moved to Queensland.
"According to relatives the MP smoked tailor made cigarettes and kept them in his top shirt pocket," she said.
"He also liked to wear grey King Gee type long pants and long sleeved checked shirts."
Det Sgt Ingram said Mr Briggs may have spent some time in Corrective Services Custody in the 1970s.
However, there are no confirmed sightings of Mr Briggs since he was last seen at Mullumbimby in 1972.
