A Complex Case of Alleged Maternal Murder and Drug Overdose
A trial in the Brisbane Supreme Court has revealed a deeply troubling case involving the alleged murder of a young man by his mother, who is accused of administering an overdose of painkillers through a fruit smoothie. The case centers around Maree Mavis Crabtree, 59, who is facing charges for allegedly killing her 26-year-old son, Jonathan, on July 19, 2017, in their family home north of the Gold Coast. She is also accused of attempting to murder him earlier that year.
The incident occurred after years of what the court has heard were significant personal struggles, including Jonathan’s history of drug use and mental health challenges. According to the prosecution, Crabtree concealed prescription medication in a fruit smoothie, leading to Jonathan’s death. Following the incident, she reportedly filed a $125,000 insurance claim, which has raised questions about her motives.
Testimony from a Former Partner
One of the key witnesses in the trial was Rebekah Millard, who dated Jonathan from 2012 to 2013. During her testimony, she described how Jonathan had experienced an overdose of drugs approximately eight months into their relationship. She confirmed that he used tramadol, a common painkiller, but never mentioned taking oxycodone, another opioid that was later found in his system.
Ms. Millard also spoke about Jonathan’s emotional instability, noting that he often had wild mood swings and would threaten self-harm. She described two distinct sides to his personality: one that was cheerful and carefree when around friends, and another that was more withdrawn and troubled when they were alone.
A History of Mental Health and Legal Issues
The court was also told about Jonathan’s history of mental health struggles and legal troubles. He had been charged with robbing a chemist, and a car accident in 2015 left him with permanent injuries that required ongoing physical care. This added to the complexity of his situation, as he relied heavily on his mother and sister, Tara, for support.
Crabtree lived in the same house as Jonathan and his sister, and there were reports of tension within the household. A neighbor, Vicki Inglis, testified that Crabtree had once said Jonathan was “eating her out of house and home” and had the “brain capacity of a six-year-old.” These comments were made during conversations between the time of the car accident and Jonathan’s death.

Allegations of Planning Harm
Another witness, Ms. Inglis, provided further details about Crabtree’s behavior. She stated that Crabtree had discussed the idea of putting something in one of Jonathan’s syringes, although she did not specify whether this was intended to harm him. The defense attorney, Angus Edwards, questioned whether Crabtree had explicitly said the purpose was to cause harm, but Ms. Inglis denied that.
These statements have contributed to the growing evidence against Crabtree, suggesting a pattern of behavior that may have led to the tragic outcome.

Ongoing Trial and Future Testimonies
The trial is expected to continue for another four weeks, with dozens more witnesses set to testify before Justice Martin Burns. The case remains complex, with both the prosecution and defense presenting conflicting narratives about Jonathan’s actions and Crabtree’s intentions.
As the court continues to examine the evidence, the case highlights the difficult intersection of mental health, family dynamics, and the legal system.
