Biannca Edmunds found guilty of murdering ex

A mother who plotted with her husband to kill her ex-lover has been found guilty of murder despite being 170km away when the trigger was pulled.

An evil mother who plotted with her husband to kill her ex-lover has been found guilty of murder despite being 150km away when the trigger was pulled.

Biannca Edmunds, 36, heard the verdict of a 12-person jury in Victoria’s Supreme Court on Saturday after they’d been deliberating for just one day.

The jurors unanimously agreed that Edmunds was in on the murderous plot and goaded her husband of only two weeks, Glen Cassidy, to kill Michael Caposiena.

She had denied any involvement, and claimed Cassidy, 49, acted alone.

It was the second trial she had faced this year, with the first jury discharged after failing to reach a verdict.

The re-trial heard how Edmunds and Mr Caposiena, 32, had a young son together, and that she was not happy he wanted spend more time with the boy after being absent for the first two years of his life.

Witnesses, including Edmunds’ own mother, Ellen Edmunds, told the court how Edmunds had repeatedly barked that she wanted Mr Caposiena out of her and her son’s life.

Cassidy’s friend Paul Bonner also testified how he heard the couple arguing about Edmunds’s ex, saying she called her husband “spineless”, “piss-weak” and a “coward”; and that “if you were a real man, you’d take care of it”.

She continued that if he had “any f---ing balls” then he would go deal with Mr Caposiena.

Prosecutor Neill Hutton painted Edmunds as the manipulator who would use kinky sex to have a hold over her doting husband, who was almost 20 years older than her.

“There’s evidence that she said to people while she was having sex with Mr Cassidy, she would not let him orgasm until he promised to kill Michael,” Mr Hutton said.

Mr Hutton said Edmunds also told her husband: “If you shoot him, it’ll be like I pulled the trigger.”

Inside their Shepparton home, he said the newlyweds concocted the murderous plan, surveilled Mr Caposiena’s Westmeadows house and sourced a gun.

He said they wanted to catch him unawares in his Pascoe St unit, so they drew a map of the surrounding area identifying where street lights, security cameras and barking dogs were.

But Edmunds was to be out of town in Darwin with her husband’s mother when the plot was executed to give her an alibi.

Telephone calls between the pair while she was interstate hinted at their plan, with the prosecution saying they spoke in code with “job” meaning the murder.

On March 7, 2016, Cassidy rang her and said: “Yeah, well, I’ll get this job finished today so that we don’t have any...”, before she interrupts, “I hope you do, I want to celebrate”.

Edmunds then said: “Yeah, just don’t get all funny after the job.”

Cassidy replied: “Nah.”

“Don’t hurt yourself,” Edmunds added.

“Nah, nah. That won’t happen either,” he told her.

But five days later, on March 12, 2016, both Cassidy and Mr Caposiena would be dead.

Cassidy drove to Mr Caposiena’s Westmeadows unit on that day and ambushed him as he answered the front door.

During a wrestle, he put the gun to Mr Caposiena’s head and fired, killing him instantly.

But what he didn’t prepare for, was a suspicious Mr Caposiena had answered the door with a knife after his partner, Silvana Silva, had alerted him that she saw Cassidy walking past the window.

Before being shot, Mr Caposiena managed to stab his attacker, who would later collapse from blood loss and die at the scene.

Among Cassidy’s last words were “Tell Biannca I love her” and “I shot Michael”.

The court heard Edmunds was in Shepparton on that day, having returned from Darwin disappointed her husband had failed to complete the hit while she was away.

To distance herself from what was about to go down, police say she wrote a text message to herself from Cassidy’s phone, claiming he was about to do something “absolutely f---ing stupid” and that “if I get caught I want them to know you had nothing at all to do with this”.

She then replied, in what would be their last message to each other: “Don’t be so bloody stupid.”

Police did not charge Edmunds with murder until June 2019, extraditing her to Victoria from Canberra where her and her children were living with her father.

She had been interviewed by police twice before then in December 2016 and April 2018.

In one interview, she became emotional and said any suggestion that she was involved was “absurd”.

“I’m not a psycho,” she said. “I have never wished anyone dead.”

Justice Lex Lasry will sentence her at a later date.
