Despite his claims of innocence regarding the murder, the jury found Rebelo guilty following a seven-week trial in the Perth Supreme Court.

Rebelo's financial troubles, including significant debt and failed cryptocurrency investments, were revealed as key factors in his motive to kill his mother to maintain a facade of wealth.

Rebelo's sentence was backdated to November 22, 2022, when he was taken into custody, and he will serve a combined sentence of 13½ years for various fraud charges concurrently with his murder sentence.

Colleen Rebelo, 58, was found dead in the shower of her Bicton home in May 2020 by her youngest son, Fabian, and her death was initially deemed non-suspicious by first responders.

While the exact details of her murder remain unclear, the court concluded that Colleen was likely smothered by her son, who had been planning the crime for months.

Shortly after her death, Rebelo attempted to claim over $1 million from three life insurance policies, prompting an investigation when an insurance employee flagged his suspicious claims.

During the trial, Rebelo pleaded guilty to fraud charges related to the insurance claims but denied responsibility for his mother's murder, despite admitting to forging documents to support his fraudulent scheme.

The court described the crime as cold-blooded and integral to a fraudulent scheme, with Justice Bruno Fiannaca emphasizing the betrayal of trust involved.

Victim impact statements from Colleen's family highlighted the profound emotional toll of her murder, emphasizing the deep bond shared with her children.

At the time of the murder, Rebelo was in a relationship with social media influencer Gracie Piscopo, and the couple was over $100,000 in debt.

Andre Zachary Rebelo, a cryptocurrency trader, has been sentenced to 25 years in prison for the premeditated murder of his mother, Colleen Rebelo, motivated by a desire to claim $1.15 million from life insurance policies he had taken out shortly before her death.

Outside the court, Rebelo's father expressed sadness over the situation, stating the family still does not know what truly happened to Colleen.
