WHAT PETER DANSIE DID:
* Peter Rex Dansie killed his wife Helen, 67, by pushing her wheelchair into a pond in Veale Gardens in the Adelaide parklands in 2017
* The 71-year-old told police he jumped into the pond to try to save her but couldn't and got out to call triple zero
* He told the emergency operator he tried to keep Mrs Dansie's head above water and manoeuvre her to the edge of the pond in his unsuccessful rescue attempt
WHAT THE TRIAL JUDGE FOUND:
* In a trial by judge alone, Supreme Court Justice David Lovell ruled Dansie had planned the killing for some time
* He said Dansie's motives were financial, and his desire to pursue a sexual relationship with a woman in China
* The judge described the killing as "evil and despicable" and the "ultimate act of domestic violence"
WHAT THE VICTIM'S FAMILY SAYS:
* Her son Grant Dansie says justice has finally been done and he hopes the strong sentence will send a message about protecting the rights of the most vulnerable
* Her cousin Grant Battersby says Dansie was driven by his "toxic ego" and thought he just could "dispose" of his wife because she had become a financial burden
WHAT HAPPENS NEXT:
* Dansie will begin serving a life sentence with a non-parole period of 25 years
* He will be in his mid-90s before being eligible for release, though given his health issues, including diabetes and a heart condition, he is likely to die in jail.
* He has been granted leave to appeal his conviction, with a hearing to be held in May after his lawyer described the guilty verdict as unsupported by the evidence
