Born with amphetamine already in his blood, Baden Bond spent 18 months in state care before he was released to parents that did not want him.
These are the allegations laid out in dual charges of murder against his parents, 43-year-old Dina Colleen Bond and Shane Arthur Simpson, 49.

Baden's father called him 'evil'
The parents of Baden Bond are charged with the toddler's murder, ten years after he disappeared from his Logan home. Nine News
Described by his own mother and father, police allege, as "evil" and a "little c---", Baden lived in a dark room smelling of urine and was abandoned in a park to die less than half a year after coming back home, according to documents included in an affidavit by an Office of the Director of Public Prosecutions legal support supervisor tendered to the court during Ms Bond's unsuccessful bail application on Thursday.
A protective supervision order imposed by a Queensland magistrate months earlier, in January 2007, did nothing to save him.
Despite multiple visits by the Department of Child Safety in the months after his presumed death in March or May of that year and a warning to NSW authorities, Baden slipped off the radar.
It would be September 2015 before his absence caught the eye of police investigating an unrelated crime, another four months until he was declared missing and more than a year again before his parents were charged.
Police allege the 22-month-old was subject to "prolific abuse and neglect", hog-tied in a cot, found covered in urine and faeces and bashed by siblings while his mother laughed.
For her part, Dina Bond's lawyers argued the case against their client was circumstantial and the evidence "very tenuous".

A body has not been found, despite police digging up the family's Logan home, south of Brisbane, in 2016, and police do not allege any specific act of violence caused Baden's death.
"At best the Crown case can be put as a proposition or put in terms of 'if it was not one of them then it must have been the other' and that's the height of the Crown case," defence counsel Dennis Kinsella said as Ms Bond was denied bail in the Supreme Court on Thursday.

Taken from his drug-using mum at birth, little Baden returned to his parents' care on October 18, 2006.
Home was a nondescript, three-bedroom house in the lower income Logan suburb of Woodridge, south of Brisbane.

Baden was kept locked in the front right room, with windows blacked, filthy and stinking of urine, multiple witnesses told police.
"He's not mine, he belongs to them," Dina was alleged to have said of Baden, referencing DOCS.
It's alleged Dina said she did not want Baden. Neighbour Sheridyn Daley told police the mum would often say she did not like the boy because he was born with drugs in his system.
The mother-of-eight admitted to using amphetamine, also known as speed, just five days before his birth, according to police allegations.
One-time housemate Petah Hegarty went as far as to say Baden's mother hated it when anyone showed him love.
"You're not going in there. He doesn't f---ing deserve it," Dina allegedly said before blocking the woman from entering after she heard Baden crying.
Ms Hegarty told police Baden would be in soiled nappies all day, in long clothing to cover his skin and she regular saw him with black eyes and a busted lip.
A week after she commented on the young boy's "beautiful, curly hair", his parents shaved it off, she said.
DOCS officers last saw Baden on March 27, 2007, his last confirmed sighting before police allege he was killed in April or May.
They visited another five times without seeing the boy before Baden's family moved to New South Wales in the middle of the night in August that year, a few months after the 22-month-old's alleged death.
Police described the state of the house as "absolute squalor" and Ms Daley said it took 12 small tip truckloads for the Department of Housing and Public Works to clear the property.
It took another two months for DOCS to alert its NSW counterpart agency, FACS, that Baden was believed to be south of the border, where the Protective Supervision Order could not be enforced.
The family file noted significant child protection history concerns involving drug use, physical and emotional harm and neglect, as well as concern Baden had not been seen for months.
On October 17, 2007, a FACS officer spoke with a DOCS officer over the phone and said the department did not have the resources to monitor the family and the case plan was closed by Christmas.
Speaking to police after Baden was declared a missing person, several relatives said they asked of Baden in the decade-long gap between his disappearance and the murder charges but were variously told he was staying with family or back in state care.
Police were also given a variety of explanations for where Baden could be as they investigated his disappearance throughout 2016.
Eventually, on the day of his arrest, Mr Simpson allegedly told police he left his son in a park by the Logan River on an unknown date, believing he would be found by someone else and taken in.
"I came up with this, I don't know, brain spasm I suppose and yeah, I thought, 'oh well' and l went down there and nobody was there and l sat down there for about half an hour with him," he allegedly said, explaining that he did not want the responsibility.
"... He looked at me in a real, how do you put it, like he knew what was going to happen, you know what I mean?
"Like just his facial features, he looked at me and I could see his eyes and ... I just went through with it and I just left him there and drove away and l didn't even look back."
Mr Simpson indicated he planned to plead guilty to manslaughter of the infant, his solicitor, Kristy Bell, told Fairfax Media on Friday but the DPP was yet to confirm it would accept the plea.
