Mother jailed over the death of Queensland toddler Mason Lee

The mother of Queensland toddler Mason Jet Lee has been jailed for nine years after pleading guilty to manslaughter and child cruelty.

But with time already served, she’ll be eligible for parole in just five months.

Anne Maree Lee admitted to failing to get medical care for her son after he suffered horrific injuries at the hands of her boyfriend at his home in Caboolture in June 2016.


The 22-month-old died five days after being hit in the stomach by William Andrew O’Sullivan, rupturing his small intestine.

He also suffered serious leg and anus injuries.

Lee had left Mason in O’Sullivan’s care after storming off following a fight.

The Brisbane Supreme Court also heard the toddler had traces of methamphetamine in his system.

Prosecutor Michael Byrne QC told the court that Mason’s injuries couldn’t have gone unnoticed and the action’s of Lee were “grossly negligent”.

Mr Byrne said Lee failed to remove Mason from O’Sullivan’s care even though she knew he was prone to violent outbursts.

In sentencing, Jean Dalton said Lee abandoned the care of her child and would have known her child was extremely sick.

After already serving more than two years jail, Lee will be eligible for parole in July this year.

O’Sullivan is already serving nine years behind bars after also pleading guilty to manslaughter last year.

He must serve at least six years before he is eligible for parole.
