The father of slain Queensland toddler Baden Bond plans to plead guilty to his manslaughter, having admitted to abandoning him in a park, according to court documents.
Both Shane Arthur Simpson, 49, and Dina Colleen Bond, 42, have been charged with the boy's murder, more than 10 years after Baden was last seen by authorities.

Baden's father called him 'evil'

Ms Bond was denied bail on Thursday, as the court heard allegations the 22-month-old was seen by a family friend covered in faeces and urine in the lead-up to his disappearance in 2007.
His body was never found but police allege he was killed between March 26 and May 17, 2007, months before his family left their Logan home in the middle of the night to move to Nambucca Heads in northern New South Wales.
Summarising the prosecution's arguments, Justice Sue Brown said when the family friend cleaned Baden and told his parents to look after him, Mr Simpson replied that the boy was "evil".
Ms Bond was alleged to have referred to the boy as a "little c---" when her sister asked where he was.
Police allege he was subject to "extensive accounts of neglect and abuse", and officers were called to the family's Woodridge address before his disappearance.
Baden was allegedly left in a dark room by himself for long periods of time, hog-tied in a cot, left in a soiled nappy and assaulted by his siblings as his mother laughed.

In an affidavit filed along with the application for bail, defence counsel Dennis Kinsella said he understood Mr Simpson would be pleading guilty to manslaughter of the boy.
Mr Simpson's solicitor, Kristy Bell, told Fairfax Media the Office of the Director of Public Prosecutions was yet to confirm whether it would accept the plea.

Mr Kinsella referenced Mr Simpson's interview with police on March 16, 2017, the day both parents were charged with murder, in which he allegedly admitted responsibility for the boy's death.
"He took Baden to a park situated along the Logan River in Beenleigh and left him there," Mr Kinsella wrote.
"Baden was alive when he left him there but the park was deserted.
"He anticipated that Baden would be found by someone else."
According to a police objection to bail affidavit, Mr Simpson told officers he did not want the responsibility of caring for his son, who spent the first 18 months of his life in state care.
"I left him there," Mr Simpson allegedly told police.
"I guess I am responsible for his death."
Ms Bond's lawyer has argued evidence against his client in the Crown's circumstantial case was "very tenuous" and some of it did not relate to his client.
"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," he said in court on Thursday, arguing the prosecutors would not be able to prove their case.
According to Ms Bond's solicitor, Thomas Schafer, Mr Simpson's defence lawyer Ms Bell first indicated her client would be willing to plead to manslaughter on April 10.
"Ms Bell placed on the court record that her client was willing to plead guilty to a charge of manslaughter on an ex-officio indictment," he said.
Ms Bond has been remanded in custody and has not been required to enter a plea.
