The widow of slain Manawatu dairy farmer Scott Guy had to choke back the tears when she recalled their two-year-old son saying "dad.. bikes" on the morning her husband had been shot dead in their driveway.
Kylee Guy was giving evidence in the High Court at Wellington on Friday in the trial of Ewen Macdonald, who is accused of murdering Mr Guy, his own brother-in-law.
Police say Macdonald shot him twice, about 5am on July 8, 2010.
The Crown alleges Macdonald killed Mr Guy because he was unhappy with his future role in the family farm.
He was charged following a nine-month police investigation in a case which has sparked widespread national interest.
Mrs Guy was composed and relaxed as she recounted events - many of them mundane - in the week up to the shooting.
However, her emotions came to the surface when she recalled their son Hunter saying he heard farm bikes on the morning Mr Guy was shot.
"Dad... bikes," he said, as he was always keen to see his father when he returned for breakfast.
When she looked out and saw a truck and police car, along with her husband's farm truck at the gate, she knew something was wrong.
About seven months pregnant with their second child, Drover, she went out to see what had happened, but was told by police to go back into the house.
Macdonald's wife Anna, Mr Guy's sister, also gave evidence on Friday. The couple have four children.
She recalled her husband must have risen about 4.50am but then the first thing she knew something had happened was when another sister, Nikki Guy, came running in saying "It's Scott, it's Scott, he's dead, he's been shot".
She said her husband came in about 10 minutes later and looked pale, was shaking and looked like he had been crying.
She said Macdonald told her he had to go back out to the farm to feed out as the farm had to keep operating.
The trial, expected to take six weeks, has finished its first week.
