Kurt Davis could not have known a spontaneous decision to search the strip of motels that pepper Great Eastern Highway for his missing father would end in the most horrific way.
He could not have predicted it would culminate in a "demolition derby" with one of his father's murderers in the very motel carpark where his dad would be discovered.
It was an unlikely and eerie coincidence even Peter Davis' killers could not have factored into their plan.
A plan where money, anger and revenge collided in a seemingly middle-class family.
The youngest of 10 children, brothers Ambrose and Xavier Clarke were close. Xavier, a truck driver and father of five, was loyal to Ambrose, a religious man who was self-employed and had six children of his own.
Family ties ran deep in the Clarke clan. But it was also a trait shared by the Davis family.
Each family appeared unified as they sat side by side in a Perth court day after day for almost two months - the Clarkes to the left, the Davises to the right.
One family supporting two brothers who claimed they were being tried for a murder they did not commit, the other seeking justice.
Ambrose joined the Davis family's concreting business in 2006.
He then invested about $160,000 in a second company started by Mr Davis. But as time wore on, tensions were simmering beneath the surface.
Mr Davis suspected Ambrose was taking money from the business and doing work outside their arrangement.
By May 2009, his suspicions were so aroused he sacked Ambrose and went to police with allegations of fraud. But his complaint went nowhere.
Not about to let go of the $330,000 he believed he was owed, Ambrose engaged lawyers and hired an "intimidating" man he thought was a licensed debt collector. But by May 2011, Ambrose had not squeezed a cent out of Mr Davis.
At his trial, the prosecution would argue that by May, Ambrose was a "boiling pot of frustration" and Mr Davis was the only thing standing between him and his money. May 30 had started much like any other for the Davis family. Mr Davis said goodbye to his wife Jenni and kissed his granddaughter farewell, leaving home shortly after 6am.
When dozens of calls and text messages to Mr Davis uncharacteristically went unanswered, a suspicious text was sent to his wife saying he was "takin the day off". When he missed an important business meeting, his family knew something was awry.
By 7.40am, Mr Davis was injured, unconscious and wrapped in plastic, left to die in the boot of his car.
Injuries to his head were consistent with blunt force trauma and some kind of smothering.
He had elbow abrasions, wrist injuries and bruising to his arms.
By the afternoon, his wife had reported him missing and his family were frantically searching for him. Their search reached a devastating climax when Kurt and his girlfriend decided to check motels along Great Eastern Highway that night.
He immediately knew "something was wrong" when he saw Ambrose and two other men on Toorak Road. While trying to go back around the block, he accidentally turned into the Great Eastern Motor Lodge and was surprised to spot his father's vehicle in the carpark.
Moments later, a blue utility, with Ambrose in the front passenger seat, pulled in. Cars were rammed and pushed in something akin to a demolition derby as the ute tried to escape.
Ambrose may have thought he was lucky when police pulled him over a short time later with acid, a shovel and other equipment in his ute and let him go.
Alone in his car, Ambrose said he had been in an accident at the motel. Aware of Kurt's 000 call, the officers asked him about Mr Davis. He said he had not seen him in years and did not know his vehicle or family were at the motel. He was sent on his way.
But his luck was about to run out. Just hours later, there was a knock on the door at his Murdoch home.
Police turned to Mr Davis' GPS to unlock his final movements.
His last destination was a business in Malaga - a business googled by Xavier and called by Ambrose a week earlier. It is believed it was the same place where Mr Davis was lured to his death.
They uncovered a mobile phone registered in a bogus name by Ambrose - a phone used to call Mr Davis in the days before his death.
Police would later find Mr Davis' driver's licence, mobile phone, credit cards and a page from his missing diary in a filing cabinet in Ambrose's garage.
Xavier's thumbprints were on the plastic covering Mr Davis' body, plastic bought only the day before the murder by his elder brother. Xavier would tell police he had never met Mr Davis. He said he took his children to school that morning and worked in the afternoon.
Ambrose testified he went to a Guildford post office, dropped equipment - including the plastic - at a building site in Northbridge and then went to morning Mass.
He said he had been at the Rivervale motel to meet the debt collector.
He said his brother dropped by the night before, helped him load his ute and refolded the plastic and there was nothing sinister about the calls at odd hours between them.
On Tuesday, after 35 days of evidence, the jury took less than three hours to convict them of murder.
With the verdict came tears of relief from a grieving family, who say justice has been served, and tears of disbelief from a family confronted with the prospect of the brothers spending life in jail when they are sentenced on December 17.
