A woman who stabbed a man to death and then licked the knife used in the attack has been found guilty of murder.
Leanne Carol Prak, 42, stood trial in South Australia's Supreme Court accused of murdering 65-year-old Michael McEvoy, known to his friends as 'Macca', at his Holden Hill unit in May last year.
She pleaded guilty to the lesser charge of manslaughter, which was not accepted by the prosecution.
The trial heard that during an argument she stabbed Mr McEvoy in the chest and then licked the blade of the knife and said to a friend who witnessed the attack "now you can see what I'm capable of".
Justice David Peek imposed a mandatory life sentence, with submissions on a non-parole period to be heard in November.
Prak's lawyer, Grant Algie QC, earlier told the jury that although his client admitted to killing Mr McEvoy, the crucial issue was her intent.
The jury was told the prosecution had to prove intent to kill or cause grievous bodily harm in order to prove the crime of murder.
In his closing address to the jury, Mr Algie said Prak's state of intoxication, which amounted to a blood-alcohol reading as high as 0.37, might have explained some of her behaviour.
He conceded her actions after Mr McEvoy's death were "bizarre and offensive" but said they were not "accompanied by the intent to kill or to do grievous bodily harm".
"They are weird, they are distressing, they are consistent with somebody who is seriously affected by alcohol but they don't go in any way to prove the requisite intention that this trial is all about."
Victim was stabbed after 'sarcastic jibe'
But prosecutor Chris Edge earlier told the jury in his closing address that stabbing Mr McEvoy in the heart, then seven times in his back, was evidence of Prak's intention.
"It comes down to this: she was angry. She chose to get a knife. She chose to wield a knife. She chose to stab Macca in the chest over little more than a sarcastic jibe, she chose to lick the knife," he said.
"And after all of that, whilst Macca lay slumped, gasping, and again asking that question of why, she chose to stab him seven more times to the back and finish what she started moments earlier.
"That reveals, I suggest, all you need to know about her intention in this case."
Mr Edge said Prak was an "alcoholic" and could handle her alcohol well without necessarily losing self-control, with a friend telling the court she would regularly drink 15 to 20 stubbies of beer and up to three litres of wine a day.
In his closing address, Mr Algie claimed there was a "degree of fondness" between his client and the victim.
"They were burdened by addiction, a degree of homelessness and probably [the] lack of supports that we all enjoy," he said.
It took the jury less than two hours of deliberations to find Prak guilty in a unanimous verdict.
Mr McEvoy's family members yelled "yes", embraced and cried as the verdict was delivered.
