Bloody footprints, missing teeth, a change of clothing and a lie.
These are some of the clues prosecutors allege link a Melbourne woman to the murder of her partner's elderly father.
Danielle Lee Birchall, 48, has been accused of fatally assaulting Kon Kritikos while he was alone at home in Melbourne's north.
The 87-year-old man was heard moaning and found badly beaten on the floor of his Coburg property by his son George and Birchall on November 11, 2020.
He was taken to hospital but died from his injuries about two weeks later.
Birchall has pleaded not guilty to murder and a jury of 14 were empanelled in Victoria's Supreme Court on Tuesday.
Prosecutor Daniel Porceddu told the jury Birchall left her partner at their home on November 11 and drove to Mr Kritikos' house, about 3.30pm, where he was alone as his wife was in hospital.
Mr Porceddu said she knew Mr Kritikos had large amounts of cash inside the property and Birchall needed $8000 to pay for a car she was due to pick up the next day.
When she was arrested, Birchall was found to be carrying $6535, he told the jury.
He said Birchall entered the home and struck Mr Kritikos several times across his head and face with an unknown object.
She then spoke to a concerned neighbour over the backyard fence before leaving.
She returned later that evening with her husband as they were driving through the area after a night out with a friend.
The couple found Mr Kritikos lying on floorboards surrounded by blood in the hallway, moaning but still semi-conscious.
George Birchall asked his father "who did it?" to which Mr Porceddu alleged he replied "her, her, her" by which he meant Birchall.
She called an ambulance and Mr Kritikos was taken to the Royal Melbourne Hospital in a critical condition, but he died on November 24.
Mr Porceddu said the prosecution relied on bloody footprints found at the crime scene, which he alleged belonged to Birchall.
Further, he claimed Birchall had incriminated herself during her police interview, when she admitted going to the Coburg home that afternoon and speaking to Mr Kritikos through the back door.
"You can use this lie as an implied admission of guilt by the accused," he told the jury.
He said she changed clothes after visiting the home and those items have never been recovered.
Mr Kritikos was also missing several teeth when he died, three were found at the crime scene but the whereabouts of two teeth remain unknown, Mr Porceddu said.
Birchall's barrister Chris Pearson said his client had nothing to do with the fatal assault and identity of the killer would be an issue during the trial.
"He was treated in a way that no human being should be treated," he told the jury.
"She simply is not the person who caused any of those terrible injuries."
The trial before Justice Christopher Beale continues on Wednesday.
