Three charged in NSW burnt body case

Three people have been charged over the death of Logan woman Sabrina Bremer, whose badly burned remains were found on the side of a dirt road in far northern NSW.

A 28-year-old Woodridge man and a 27-year-old Kingston woman were both charged with murder and interfering with a corpse, while a 38-year-old Wynnum man has been charged with being an accessory after the fact of murder, police say.

The trio are expected to appear in Beenleigh Magistrates Court on Thursday.

Ms Bremer's body was found at Pollards Road, North Tumbulgum on August 18, two days after she was last seen alive.

The 34-year-old's white Camry sedan was found in the Logan suburb of Woodridge, south of Brisbane, five days after her body was found, following a public tip-off.

Police say the car was last seen in the Logan area on the night of August 15.

Forensic investigators scoured the sedan for any clue as to how Ms Bremer's badly burned remains ended up beside a dirt road about 100km from her home.

Police say they will allege Ms Bremer was murdered in southeast Queensland and her body was dumped in northern NSW.
