The incident in the early hours of 18th July has prompted two retaliatory arson attacks at the Tanna Lodge resort, owned by Hugh Lowe.
His son, Ned Lowe, has been held in custody on Tanna and charged with murder.
The officer in charge of state prosecutions for Tafea Province, Willie Ketio, says police are alleging that blood samples were found on the accused's vehicle and a knife was found at the scene.
