Angelika Gavare thought she got away with murder, until these errors undid her web of lies.

Angelika Gavare thought she had pulled off the perfect crime: after bludgeoning her elderly neighbour to death, she hacksawed off her head, hands and feet and hid the body in dense bushland across the street from her home.

The mother of two then began weaving a web of lies to the police investigating 83-year-old Vonne McGlynn’s disappearance in December 2008.

But her stories weren't adding up, and they soon discovered the truth.

Gavare's chilling police interviews were aired on Channel 7's true crime show, Murder Uncovered, last night, showing how her perfectly rehearsed story was soon undone.

Five days after she murdered her elderly neighbour - to steal the deeds to her home - the then 35-year-old attempted to withdraw $2,000 from her neighbour's bank account.

She presented the bank with a power of attorney document, that she said had been signed by Vonne.

When police asked her about the document, which they knew had been forged, Gavare said her neighbour had given her permission to withdraw cash while she went away on holiday.

"Is there any reason why she couldn't get the money out for you before she went away?" a police officer asked in one recorded interview.

"It strikes me as quite odd that a lady that goes to the bank very regularly and knows how much money she's got, and is quite with it, would then just decide to hand over her credit card and say ‘Get out what you need’," he said.

Gavare could only respond that she didn't know why her neighbour had done what she did.

When police also found Vonne's fridge full of food and her glasses still inside her home, they knew Gavare wasn't telling the truth.

After searching her computer, they found searches relating to true crime, power of attorneys, forensics and land titles.

They even found a table that belonged to Vonne in Gavare's home, and a letter that read, "I deeply regret what I have done in the past last month".

But it wasn't until police searched the bushland opposite Gavare's home on February 23, 2009 that they found the evidence that she had murdered her neighbour.

"The last real area that we came to search was the area directly in front of Gavare's house," an officer investigating the case told Murder Uncovered.

"And really that was left to last because in all honesty, it was really unlikely that you would dispose of those remains directly in front of your house."

Police uncovered the remains of Vonne McGlynn's torso in the dense bush. Tragically, her head, legs, arms, hands and feet have never been recovered.

Angelika Gavare was jailed for life, with a minimum 32-year sentence for the murder.
