Police investigators are now calling for sightings of a second vehicle in relation to the Amber-Rose Rush homicide inquiry.
The 16-year-old was found dead at a Clermiston Ave, Dunedin, house last Saturday morning. A 30-year-old medical professional has been charged with killing her.
He was granted interim name suppression and remanded in custody by consent until he appears in the High Court on February 20.
Earlier this week, police searched a waterway near Blackhead Quarry, with poles and metal detectors.
Detective Senior Sergeant Rob Hanna said the search turned up ``an item of interest''.
``We are still wanting to identify the occupants of a dark-coloured vehicle, believed to be a Toyota Camry or similar, which was parked in the car park at Blackhead Quarry.
``These people may be able to assist with the investigation.''
He said the vehicle was in the car park between 11.30pm on Friday, February 2 and 12.30am on Saturday, February 3.
``We are also interested in any sightings of a silver two-door BMW that is believed to have travelled from Dunedin to Balclutha between midnight and about 2am on Saturday (February 3).
Mourners attending the funeral of Miss Rush tomorrow have been asked to wear their brightest clothes.
The service will be held at Hope and Sons Chapel, in Andersons Bay Rd, at 12.30pm.
Her funeral is expected to be a colourful celebration of her life, a family member said.
``Amber loved bright colours, so in respect of her wishes, please do not wear any black clothing to the service.''
The ceremony was open to the public because she was so well known, and a large gathering was expected.
A private cremation will be held following the ceremony.
