'Only he can be the killer' Crown lawyers have been laying out their case as to why they believe David Tamihere is responsible for the death of two Swedish backpackers 34 years ago.
He was convicted of the murders of Urban Höglin and Heidi Paakkonen in 1990.
The case is at the court of appeal because the former Governor-General declared a royal perogative of mercy, which triggered the appeal hearing.
Jemima Huston has been in court.
