An "item of interest" has been located by police at a Dunedin quarry as the investigation into the death of 16-year-old Amber-Rose Rush continues.
The teenager was found dead on Saturday morning at her home in Dunedin.
In a statement today Detective Senior Sergeant Rob Hanna confirmed an "item of interest" had been located at Blackhead Quarry.
Police have been searching a quarry pond in the suburb of Blackhead and say they'd like to speak to the occupants of a black Toyota Camry, seen in a carpark at the quarry in the early hours of Saturday morning.
Police are also appealing for 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 3 February.
A 30-year-old man has been charged with murdering the girl and will reappear in court later this month.
