Two days after a Dunedin teen had her throat slashed - police were already tailing a local doctor

32-year-old Venod Skantha has pleaded not guilty to murdering Amber-Rose Rush late on a Friday night early last year.

Today his then-girlfriend Brigid Clinton took the stand.

Skantha's defense Jonathan Eaton, QC, told Clinton that from two days after the death - police were following her and Skantha.

The Court heard the movements of Skantha, Clinton and a teenage friend.

They visited Amber-Rose's mother, before the couple had drinks at home - then went out again for petrol and KFC.

Skantha was arrested later that night.
