A twisted psychologist videoed himself acting out a gruesome murder while wearing a black latex suit and before launching the savage attack for real.
Luke David Fawcett, 29, stabbed his elderly neighbour to death as part of a sick fantasy – and then used the same knives to kill her brother the following day.
He was sentenced to a minimum of 34 years behind bars after being found guilty of the 2020 murders of Marie Collins, 66, and Wayne Johnson, 62, at an apartment block in Perth’s Victoria Park.
The sickening video discovered by police on the killer’s mobile phone was a key part of evidence that saw the Western Australian Supreme Court jury convict Fawcett in just half an hour.
‘We can do this the easy way or the hard way,’ Fawcett can be heard saying in the video played to the courtroom.
‘If it’s the hard way, you will be severely caught and I will eventually kill you.’

Luke David Fawcett, 29, stabbed his elderly neighbour to death as part of a twisted fantasy and then turned the knife on her brother the following day
Prosecutor Justin Whalley SC told the court the knifeman’s unnerving footage – which showed Fawcett in a skintight bodysuit brandishing a hunting knife and making murder threats – was ‘a rehearsal video’ for the frenzied stabbings, ABC reported.
Fawcett lived next door to his victim at their Leonard St unit complex and on Easter Saturday, 2020, he broke into her home, inflicted 12 severe lacerations and slashed her throat.
For the next day or so, the trained mental health professional ‘made himself at home’ in Ms Collins’ apartment drinking beer and smoothies while she was wrapped up in a tarpaulin dead on the floor.
Mr Whalley said Fawcett showed ‘callous indifference of the highest order’ and a ‘level of depravity that defies adequate description’.
The following day Mr Johnson arrived at the address to check on his sister after family members were unable to contact with her.
He was also set upon by Fawcett in a ‘terrifying and brutal’ knife attack.

But the altercation led to the killer’s downfall as Fawcett was forced to check himself into the hospital with a shoulder injury.
He told medical staff and his grandmother who took him there that he had fallen down a set of stairs while holding a knife, the court heard.
Investigators tracked him down shortly after arriving at the blood-soaked double murder scene. A detective looked in the window of his car parked outside the apartment block and found a Bunnings hardware store receipt for a tarpaulin.
Inside the unit, forensic crews also found a treasure trove of evidence including the murder weapons – a bread knife and hunting knife – latex gloves, beer bottles and several protein smoothie bottles.
Two sets of handcuffs were also recovered along with a taser that had Fawcett’s DNA on the handle and trigger and Ms Collins’s DNA on the barb.
Police seized Fawcett’s mobile phone and found a screenshot of a map, along with the disturbing video.

Detectives travelled 200 kilometres south of Perth to the location and discovered a partially dug grave with a black duffel and a shovel. Inside the bag were several of the same protein smoothies found at Ms Collins apartment.
Two handwritten ‘to do lists’ were also found in the killer’s car with a murder checklist titled ‘equipment’ including items like: ‘quiet shoes’, ‘baseball bat’ and ‘cable ties’.
The second list was named ‘interrogation’ and listed ‘pepper spray to the eyes’ and ‘potential locations’.
Further inquiries found that Fawcett made several trips to Bunnings where he purchased a shovel, a tarpaulin, rope and duct tape.
Soon after knifing Ms Collins, he returned to Bunnings to buy a larger tarpaulin after discovering it was too small to wrap up her body.
Fawcett denied he killed Ms Collins, claiming an unknown intruder carried out the crime. But he did admit to killing her brother, arguing it was self defence after Mr Johnson attacked him thinking he had murdered his sister.

He also claimed the video was part of home invasion role play for a couple online and the ‘to do lists’ were about video games.
Justice Jennifer Smith described Fawcett’s claims ‘a litany of lies’.
His motives for the murder still remain a mystery but investigators suspect he had a fantasy about killing Ms Collins, living in her newly renovated apartment and stealing her money.
The victim’s family said the ordeal has been a 22 month nightmare and that they will remember the church-going siblings as ‘loving and compassionate’ people.
‘The empty seats at our table will always be a constant reminder of the absence at our family gatherings,’ their sister Helen Batina said outside court.
‘The void left by Marie and Wayne will never be filled but we will endeavour to move on with our lives and honour them by walking in love, compassion and faith.’
