Mason Jet Lee: The abuse before his death exposed in court
A teen charged with the manslaughter of Caboolture toddler Mason Jet Lee allegedly taunted him before his death and was aware that he had been vomiting for five days, a court has heard.
Mason was found dead about 12.30am on June 11, and police said he had suffered horrific head-to-toe injuries.
On Saturday, his mother Anne-Marie Lee, 27, her former partner Andrew O'Sullivan, 35, and Ryan Robert Hodson, 17, were each charged with manslaughter over his death.

Police allege they failed to provide Mason with medical treatment despite his obvious injuries, and are yet to determine how the injuries were caused.
Mr Hodson faced the Caboolture Magistrates Court yesterday, and was refused bail.
Police prosecutor Aaron Murray told the court Mason was found with bruising to most of his body, and that "it would be impossible for any person not to be cognisant… to the extent of those injuries".

"[Mr Hodson] was aware the child had been vomiting for five days straight," Mr Murray said.
The police case also includes audio recordings from the home where Mason died, and the court heard that Mr Hodson allegedly insulted Mason in the days before his death.
"Mason, shut up ----," Mr Hodson can allegedly be heard saying.
"Come on ----, you walk like a spastic."
Members of Mr Hodson's family sobbed in court as his bail was refused.
Mason's aunt Shuntel Lee also attended Mr Hodson’s court appearance, and said the allegations were "very heartbreaking".

Last month, she told A Current Affair she had contacted child safety authorities about Mason last August and was angry about their lack of response.
Mason Lee was only 21 months old when his life was cut tragically short. Police now need your help to find Mason's killer, after he suffered horrific injuries over a period of months before his death.
Outside court, supporters of Mason and Mr Hodson clashed.
"No child deserves what that child went through," one man said.
"Do you even know what happened? You don't, do ya? Leave him alone," a woman interjected.
"I'm not going to let it go," the man replied.
Mason's mother was also refused bail yesterday, with Magistrate Graham Lee – of no relation – finding there was an unacceptable risk of her not appearing at future court dates.
"In balancing all considerations, you have no history, (but) this is a very, very serious case," he said.
Mr O'Sullivan briefly appeared in court on Saturday and did not apply for bail.
Last month, he told 9NEWS he did everything he could to save Mason.

On Saturday, Detective Inspector Paul Schmidt said police had not yet established how Mason's injuries were caused.
"Police will be alleging that the child died as a result of peritonitis due to a ruptured duodenum," he said.
"The injuries would have been obvious, would have been deteriorating and would have been significant over a period of time leading up to his death."
Ms Lee's case has been adjourned to the Caboolture Magistrates Court on August 16.
At least 40 officers, including members of the homicide squad and child trauma task force, have been involved in the investigation into Mason's death.
Anyone with relevant information is urged to contact Crime Stoppers on 1800 333 000.
