A mother, Maree Mavis Crabtree, is on trial for the alleged murder of her 26-year-old son, Jonathan, following a series of disputes over finances and living conditions in their family home, located north of the Gold Coast. Prosecutors claim that on July 19, 2017, Crabtree fatally administered an overdose of painkillers disguised in a smoothie, after which she filed a $125,000 insurance claim.
The trial, taking place at the Brisbane Supreme Court, has also heard that Crabtree attempted to murder Jonathan earlier that same year in January. Preliminary hearings revealed that Jonathan was found dead on his bed, with paramedics discovering him in a compromising position. An autopsy indicated that the cause of death was excessive oxycodone in his system, a medication that had not been found in his room. The Crown alleges that Maree deliberately prepared a drink using a blender that contained the lethal substance.
Key evidence to be presented includes testimony from Crabtree’s daughter, Tara, who recalls being asked to keep watch while their mother prepared the drink and later hearing Jonathan in distress throughout the night. Tara further stated that her mother informed her of Jonathan’s passing the following morning, but reportedly delayed calling emergency services for several hours.
The jury was informed that Jonathan had a history of substance abuse and had previously engaged in criminal activities, including the robbery of a chemist. His physical limitations, resulting from a car accident in 2015, necessitated ongoing caregiving, placing additional strain on the family dynamic. The deteriorating living situation reportedly contributed to Crabtree’s psychological distress, with her feeling unable to financially resolve their housing arrangement, as the home was co-owned by her children.
Evidence collected by investigators includes multiple bottles of liquid oxycodone found at the Crabtree residence and a smoothie blender that tested positive for drug traces. The Crown intends to argue that Crabtree believed her son’s criminal actions jeopardised their family finances, leading her to contemplate his death as a solution.
Crabtree, aged 59, has pleaded not guilty to the charges of murder, attempted murder, and fraud. Her defence team, led by barrister Angus Edwards, is expected to present their case as the trial unfolds over the next five weeks, during which 60 witnesses are set to testify. The case has garnered significant public interest, drawing attention to the complexities of familial relationships under pressure from financial turmoil and mental health struggles.
