After 35 years of 'normal and loving' marriage a wife shot her husband before calling an ambulance and saying 'he's just whinge, whinge, whinge and now I'm the bad guy' as he lay dying

A woman shot her husband of 35 years before complaining to a Triple-0 operator that 'he's just whinge, whinge, whinge'.

Debra Jane Alicia Holmes, 55, was found guilty of murdering Wayne Chappell at their home in Muja, south of Perth, in July 2018.

An argument broke out between the couple as they were drinking in their shed, when Mr Chappell grabbed Holmes' hair and threw her outside.

Holmes, whose blood alcohol reading was 0.204, grabbed a .22 calibre rifle from the house and shot her husband in the stomach, the ABC reports. 

She then called emergency services and told the operator Mr Chappell was mean and nasty, and revealed she'd rather be in jail than stay with him.  

'I try to be nice to him every day… he comes home and he's just whinge, whinge, and now I'm the bad guy,' she said.

Chief Justice Peter Quinlan acknowledged that Holmes didn't intend to kill her husband, but said the shooting was still 'quite deliberate'.

'In the end, your actions were motivated by selfishness, anger and stupidity, fuelled by your drunken state,' he told her.

Chief Justice Quinlan said the couple, who share two children and four grandchildren, had a 'normal, supporting and loving' relationship. 

He also pointed out that, by Holmes' own admission, the night of the murder was the only instance Mr Chappell had ever done something bad to her. 

Holmes on Wednesday was sentenced to life in prison, with a 14-and-a-half year non-parole period.  

With time already served, she will first be eligible for release on parole in January 2033.
