Mason Lee: Accused left child to have sex, court told

CABOOLTURE toddler Mason Jet Lee was alone with only a five-year-old boy to supervise him, while his stepfather went out for sex, a court has heard.

The 21-month-old toddler died earlier this year in circumstances that shocked the country.

It prompted a petition now supported by 30,499 people calling for child safety law reforms and the creation of Mason Jet Lee's Law, which would stop children being sent home if doctors suspect they are being abused.

The boy is thought to have been struck hard enough that his bowel was perforated, and caused faeces to bleed into his abdomen.

He was allegedly not taken to a doctor, despite days of vomiting.

Stepfather William O'Sullivan, considered the boy's caregiver, is facing charges of manslaughter.

Mason's mother Annemarree Lee and a 17-year-old housemate also face manslaughter charges.

O'Sullivan applied for bail in the Caboolture Magistrates Court on Thursday, which was denied.

Prosecutor Sergeant Liesl Stephenson said O'Sullivan changed his story several times about what happened the night that Mason died, according to reports from the Courier-Mail.

Police believe O'Sullivan left the children alone so he could visit Mason's mother for sex.

"CCTV footage shows the defendant leave the children unsupervised after 10pm on the night of Mason's death," she told the court.

The court also heard O'Sullivan took photos of the young boy alongside his own vomit, which he texted to his friends as the toddler lay dying.

"That's the extent of care that this defendant has shown to a child who is clearly dying." Sgt Stephenson told the court.
