Bryan Guy doesn't know what he will say to Ewen Macdonald when he finally meets him face to face.
They haven't seen each other since Macdonald's trial in July last year when a jury acquitted him of the murder of Mr Guy's son, Scott. He did, however, admit a number of other crimes.
It is a meeting that Mr Guy admits is inevitable, but it is one he is neither dreading nor looking forward to. But knowing Macdonald would be eventually released, possibly as early as next week, meant he and wife Jo were realistic about how they would be when the moment finally arrived.
"You've still got to be courteous and polite and so on."
Macdonald, 33, is the estranged husband of Mr Guy's daughter Anna, who is now living in Auckland with her new partner, Brent Jameson. The couple are expecting their first child together. Ms Guy has four children with Macdonald.
