The defence at a high-profile Dunedin murder trial has questioned the Crown's key witness.
Dr Venod Skantha is charged with murdering 16-year-old Amber-Rose Rush, who was stabbed in her bed at her Corstorphine home on February 2 last year.
A teenage associate of Skantha's has returned to the stand at the High Court at Dunedin today.
The teen has given a detailed account of how he says he was roped into driving Skantha to Amber-Rose's house the night she was killed - and later helped destroy the evidence.
But defence lawyer Jonathan Eaton says he seems to know far too much.
Other Facebook messages to his friends show inconsistencies with his earlier testimony.
He told one friend that after killing Amber-Rose, Skantha threatened him with the bloody knife.
The teen says it was just an exaggeration.
He also sent a long message to Amber-Rose's mother - Lisa Ann Mills.
He apologised to her about a picture he'd put up, and told her he wanted to say he was sorry.
"When that scum [Skantha] got me to drive to your house, I had no idea what was about to happen. He pointed a knife at me and told me he'd kill me and my family."
