Mother accused of poisoning son with spiked juice in 2017 murder trial
Consensus Summary
A Gold Coast mother named Maree Mavis Crabtree is on trial for allegedly murdering her 26-year-old son Jonathan in July 2017 by poisoning him with fruit juice spiked with oxycodone. The prosecution claims she acted deliberately, with her daughter Tara’s alleged assistance, and that she later fraudulently claimed superannuation benefits. Key evidence includes a March 2017 domestic violence call where Jonathan threatened his mother with a shovel over financial disputes, and forensic signs indicating Jonathan had been dead for hours before emergency services arrived. Both sources confirm Jonathan’s troubled background—drug use, a 2015 car crash, and a 2016 pharmacy robbery charge—though details about the January 2017 attempted murder vary. Tara’s testimony, granted immunity, is central to the prosecution’s case, while the defense challenges her credibility and suggests Jonathan may have self-administered the overdose. Contradictions exist over the location of a Spider-Man backpack, Ms Crabtree’s refusal to perform CPR, and the specifics of the January incident, highlighting inconsistencies in witness accounts.

Key details reported by multiple sources:
- Maree Mavis Crabtree is accused of murdering her 26-year-old son Jonathan Crabtree in July 2017 by poisoning him with fruit juice laced with oxycodone
- Ms Crabtree pleaded not guilty to murder, attempted murder (January 2017), and attempted fraud (superannuation claim over $100,000) in Brisbane Supreme Court
- Jonathan’s body was discovered on July 19, 2017, showing signs of death for several hours (rigor mortis, cold limbs, blood pooling) when paramedics arrived at 10:08am
- Police attended a domestic disturbance at the Crabtree family home on March 4, 2017, where Jonathan allegedly threatened his mother with a shovel over money disputes ($30 weekly allowance)
- The house was jointly owned by Jonathan and his sister Tara, with Ms Crabtree claiming financial contribution despite not being on the title
- Jonathan had a history of drug use, a 2015 car crash causing permanent injuries, and a 2016 pharmacy robbery charge (later discharged post-death)
- Tara Crabtree was granted immunity from prosecution for her alleged role in the poisoning
Points of Difference
Details reported by only one source:
- Sergeant Mathew Dowling testified Jonathan threatened his mother with a shovel ‘or ... with a shovel’ during the March 2017 domestic dispute
- Crime scene photos showed Jonathan lying sideways on a bed with an Elmo basket, iPad, iPod, and papers nearby; a Spider-Man backpack was initially reported by paramedics at the foot of the bed but Sergeant Dowling saw it at the front door
- A notepad in the Spider-Man backpack contained medication packets and prescription stickers
- Counsel described Jonathan as a ‘troubled’ young man with ongoing health issues from the 2015 crash
- Prosecution alleges Ms Crabtree ‘deliberately’ prepared the oxycodone-laced smoothie in a kitchen blender on July 18, 2017, and refused CPR due to a bad back
- Tara Crabtree testified she helped her mother by keeping lookout during the poisoning, heard Jonathan struggling/coughing after drinking it, and saw her mother crush pills in a milkshake in January 2017
- Ms Crabtree told many people Jonathan was ‘difficult and abusive’ and that his pharmacy robbery ‘put their family’s finances in jeopardy’—a reason she claimed for wanting to kill him
- Defense lawyer Angus Edwards questioned Tara’s credibility, noting she only revealed her story over two years after Jonathan’s death and is the ‘only person’ claiming her mother killed her brother
- Trial expected to hear from ~60 witnesses including neighbours, a pharmacist, and emergency services over five weeks
Contradictions
Conflicting information between sources:
- NEWSCOMAU reports Sergeant Dowling saw the Spider-Man backpack at the front door, but paramedics claimed it was near the bed (though one conceded possible movement)
- ABC states Ms Crabtree refused CPR because she had a bad back and ‘could not stay in the room with him as she thought he was then dead,’ while NEWSCOMAU does not mention her refusal to perform CPR
- ABC alleges Tara Crabtree saw her mother crush pills in a milkshake in January 2017 (first attempt), but NEWSCOMAU does not mention this specific detail about the January incident
- ABC describes the prosecution’s claim that Ms Crabtree ‘insisted’ she financially contributed to the house despite not being on the title, while NEWSCOMAU frames it as her ‘belief’ she contributed
- NEWSCOMAU states the pharmacy robbery charge was referred to the mental health court but ‘discharged following his death,’ while ABC says it was ‘discharged following his death’ without mentioning the mental health court referral
