EARLIER: POLICE are hoping members of the public can help identify a teenage girl whose body was found on the banks of the Pimpama River on the Gold Coast yesterday afternoon.

Detectives are trying to piece together a timeline of how the body came to be left on the riverbank, and are appealing for anyone who was in the vicinity of Kerkin Rd North to come forward.

They are also appealing for anyone who may have seen any suspicious people or vehicles.

Police were scouring missing persons databases after the body was revealed to be a teenage girl.

Regional crime co-ordinator Superintdnent Dave Hutchinson said the body was badly decomposed, and he could only say it was that of a teenage girl with dark hair.

He would not disclose what the girl was wearing, but said she had on “some jewellery”.

“The post-mortem is still occurring (and) we cannot say at this stage what the cause of death is,” he said.

“But circumstances like this, we will treat them as suspicious until they’re proven otherwise.”

Supt Hutchinson said the girl could be aged anywhere between 12 and 18, and police were checking missing persons records and speaking with families.

Police are wishing to hear from anyone who may know a child in that age group who is missing in the southeast corner and has not already been reported missing to police.

Police are already investigating known cases, such as that of an unnamed 12-year-old last seen at a school at Marsden in Logan last Friday.

Police put out a missing person appeal for the girl on Thursday, hours before the body was discovered.

The crime scene is still being contained, with scientific and scenes of crimes officers, and police divers on scene. Investigations are continuing.

Supt Hutchinson appealed for anyone who might have seen anything in the area near where the girl was found near a bridge at Kerkin Road North at Pimpama to come forward.
