Detectives from North Brisbane District CIB and the Homicide Investigation Unit are continuing to investigate the discovery of human remains found in a disused tank at Brighton last year.
The remains discovered on November 29 have since been identified as belonging to Wayne Youngkin who was 29-years-old when he went missing in 1986.
Mr Youngkin was previously a resident of North Street in Brighton and had a number of friends and associates in the Brighton and Sandgate areas.
Since the discovery of his remains at a North Street address, police have undertaken a series of forensic examinations of the scene, including a number of exhibits retrieved from the location.
Police are concentrating on forensic examinations of a set of vehicle seat covers recovered from the scene and are in the process of developing a DNA profile from them.
A series of photographs of the seat covers has been released (below) in the hope that the members of the public may assist in identifying the brand of seat covers from the distinctive markings and patterns on them.
Police are appealing for anyone with information about these vehicle seat covers or anyone who has information about the homicide of Wayne Youngkin to contact police.
Since the operation commenced, police have received a steady flow of information through Crime Stoppers which has assisted to progress the investigation.
On December 1 2016, police received anonymous but specific information via Crime Stoppers regarding the investigation and are appealing for this person to again make contact with police.
On December 9 2016, police received a handwritten letter at Sandgate Police Station with details about the investigation. Police are appealing for this person to again come forward.
