As the high-profile murder trial of Ewen Macdonald enters its fourth week, crucial evidence about dive- boot imprints found at the scene will finally be heard.
Ewen Macdonald, 32, is accused of gunning down his brother-in-law, Scott Guy, 31, in the early morning darkness of July 8, 2010, after growing tensions over the family farm they co-managed.
Macdonald has denied murdering Guy.
Distinctive ripple tread prints were left at the scene; prints, the Crown says, left by Macdonald.
Macdonald once owned such dive boots but they have never been found.
