The widow of slain Feilding farmer Scott Guy wept as she told a jury about events the morning her husband died.
Ewen Macdonald is on trial in the Wellington High Court accused of the murder of his brother-in-law on 8 July 2010.
Scott Guy's body was discovered by a passer-by in the driveway of his home in Aorangi Road. The 31-year old had been shot twice.
The Crown says Ewen Macdonald was concerned about inequalities he perceived in the amount of work he and Scott Guy had to do around the farm and tension arising from that led to the killing.
However, the defence says while Mr Macdonald, 32, acknowledged that he had damaged property belonging to Scott and his wife Kylee, that did not make him a murderer.
On Friday, Kylee Guy told the court she did not hear her husband leave home the morning he died.
She said later that morning their two-year-old son Hunter came into her room and became excited when he heard motorbikes outside.
Mrs Guy said Hunter called out "Dad, bike" and wondered why Mr Scott was using the bike at that time of the day because usually he used it when he was moving stock.
She said she looked outside and saw police cars, but when she went to find out what had happened an officer told her to go back inside.
Kylee Guy told the court she collapsed inside in a state of shock when she learned what had happened, then went to her room where she cuddled Hunter.
Accused was pale and shaking, court told
The accused's wife, Anna Macdonald, also gave evidence on Friday, telling the court that her husband worked on the farm in which they and Scott and Kylee Guy each had a 10% share.
Mrs Macdonald said she first heard the news that Mr Guy had been killed from her sister Nikki.
She said a short time later, her husband came home and he had been crying, looked pale and was shaking.
