The parents of slain farmer Scott Guy say they may never see the mystery of their son's death resolved.
Bryan and Jo Guy have spoken openly for the first time since their son-in-law Ewen Macdonald was acquitted two months ago for the murder of their son.
They say they are trying to move on with their lives and have not had any involvement with private investigations into their son's death.
"There are unanswered questions about who killed Scott, and while justice prevailed we are still asking the question 'Who killed Scott?' but we're trying to not dwell on that because it'll make us bitter and sad."
The Feilding farmer was shot twice in his driveway in the predawn darkness of July 8, 2010 allegedly amid growing tensions over the future of the family farm.
Bryan said the family had initially planned to get together every two weeks after the killing. But, "we couldn't recreate what we had; we found that with that one person missing it just wasn't the same".
"Now we've got to start making new memories and new traditions for the family," Bryan said.
Jo Guy, who wears a photo of her slain son in a locket around her neck, focuses on her grandchildren and on making a new life.
Both parents recalled their son's smile, a smile Jo can look at whenever she needs to with Scott's photo close to her heart in the locket around her neck.
"We just loved him. He kind of lit up a room when he came in," Jo said.
The Guys emphasised the need to stay positive about life, with Jo describing how she wakes up in the morning and thinks of something to be thankful for.
"We don't want to be bitter and twisted and angry about what happened," Bryan said.
Some people would come up on the street to talk, yet not know what to say or whether they should mention Scott.
Public support has been "overwhelming" and, at times, "healing".
"It's given us lots of strength and courage to get through it," Bryan said.
They would often talk about Scott, and wanted to keep it that way.
Work-wise, Bryan had just appointed a new farm manager, which took the pressure of him.
At some stage the farm would probably be sold.
Jo last year closed the women's fashion store Reve she ran with daughter Nikki and had since developed a love of writing and hoped to do something positive in that field.
Scott's widow, Kylee, has said she is working with private investigators to look into her husband's death, but the Guys were not actively involved in that.
"There's so many unanswered questions and rather than focus on that we've focused on the grandchildren and the family and making a new life for ourselves," Bryan said.
The four-and-a-half week murder trial in Wellington was stressful for the couple and they were relieved when it was over.
While there they were conscious of the attention the case received, such as when they went out to dinner.
"You can see everybody looking at you. You could hear people talking about it as well," Jo said.
They were not surprised to hear their daughter Anna, who was married to Macdonald, was planning to move away from Feilding.
Their other children were settling down. Nikki was in a relationship, as was Callum, who lives in Hamilton.
