The man serving a life sentence for his foster daughter Tiahleigh Palmer’s murder has been found in his prison cell to be unresponsive.
Queensland man Rick Thorburn is found unconscious in his cell on Saturday morning, in a critical condition.
He is currently in the Princess Alexandra Hospital’s intensive care unit in Brisbane.
It is understood that he had a presumed overdose of the drug.
Thorburn is on his life sentence for two years, which includes a mandatory 20-year non-parole period.
In 2018 the 59-year-old was imprisoned for life for murdering Logan girl Tiahleigh Palmer, 12, in 2015.
He dumped her body in a river on the Gold Coast in 2015, after his son Trent confessed to sexual assault.
Thorburn also pleaded guilty at the Queensland District Court late last year to 13 child sex offences.
He was awaiting sentencing for crimes including rape, and attempting to rape two young girls.
