The jury in the trial of a Taranaki man accused of murdering his son has been taken on a bus tour of sites significant to the Crown case.
David Noel Roigard, an Opunake farmer, has denied killing his son Aaron Roigard in June last year, and also denies eight charges of theft in a special relationship.
The Crown alleges Mr Roigard killed his son when he visited him in June to sign papers for a farm he thought he was buying.
Aaron Roigard, a 27-year-old father of two, has not been seen since and a body has never been found.
David Roigard's defence team said the evidence against him was circumstantial and that it needed to be proven that a death has taken place.
The trial has been set down for four weeks and is being heard by Justice Paul Heath and a jury of 10 women and two men.
