Three charged with manslaughter over death of Caboolture boy Mason Jet Lee.

Three people have been charged over the death of 21-month-old Mason Jet Lee north of Brisbane last month.

The boy’s body was found at a Caboolture home on June 11.

The child had suffered traumatic injuries in the days before his death.

Detective Inspector Paul Schmidt said the cause of death was peritonitis, brought on by a ruptured duodenum, which is the first part of the small intestine.

Peritonitis is usually the result of a fungal or bacterial infection caused by an abdominal injury or an underlying medical condition.

Detective Inspector Schmidt said the trio has been accused of failing to provide care for the toddler, but it was not clear who inflicted the boy’s injuries.

“The injuries sustained by the child would’ve been obvious, would’ve been deteriorating, and would’ve been significant over a period of time leading up to his death,” he said.

A 27-year-old woman from Caboolture South has been charged with manslaughter and is due to appear in Toowoomba Magistrates Court later today.

William Andrew O’Sullivan, 35, and Ryan Barry Hodson, 17, have been charged with manslaughter.

O’Sullivan did not apply for bail during a brief appearance in Brisbane’s Magistrates Court.

He was remanded in custody, with his case adjourned to August 8.

Hodson appeared in Caboolture Magistrates Court where his case was adjourned until Monday, when he is expected to apply for bail.

There are more Mason Lees out there: Opposition

The Opposition’s child safety spokeswoman Ros Bates said Premier Annastacia Palaszczuk and Child Safety Minister Shannon Fentiman needed to explain how the child safety system failed Mason Lee.

“Child safety is in crisis and the Minister obfuscating her responsibilities in [budget] estimates [hearings] this week was appalling,” Ms Bates said.

“She is the Minister for Child Safety – the buck stops with her and Queenslanders quite rightly want to know how the system failed Mason Lee and to make sure that it doesn’t fail any other child.

“Caboolture had 120 cases backlogged prior to Mason Lee’s death and that’s where the money needs to go — to the hardworking, frontline child safety officers.

“There are more Mason Lee’s out there and this Government needs to be held to account.

“What the Minister needs to do is to go urgently to the Treasurer and make sure that she has funding to adequately resource our frontline child safety officers.”

A spokesperson for Ms Fentiman’s office described the death as a tragedy but said they could not comment further due to ongoing police investigations.

“Every child deserves love and care. Sadly that is not the reality for every child,” the spokesperson said.
