A Queensland father has admitted to killing his toddler son in 2015.

Shane Purssell Akehurst stood in Brisbane’s Supreme Court dock this morning and pleaded guilty to the manslaughter of his little boy, Corby Mitchell Akehurst, on 27 March 2015.

The Kin Kin father also pleaded guilty to his torture, on dates between 13 November 2014 and 26 March 2015.

Corby Akehurst was almost two years old when his father killed him by throwing him into a timber bed with force with “probably everything I had” in anger.

Corby suffered a severe head injury and his life support was turned off two days later.

Akehurst initially told police and paramedics that he put Corby down for an afternoon nap and went outside.

He heard a noise and went back inside finding his child stiff as if having a seizure. The 37-year-old began CPR and called triple zero.

Akehurst later admitted that was a lie, telling police he had “anger issues which caused him to sometimes lose control.” He claims he had never bonded with Corby.

Akehurst admitted to intentionally inflicting pain and suffering to his little boy in the four-month period before his death.

He punched the toddler in the face in the two nights before he died because he wouldn’t sleep. Akehurst would also squeeze him so hard that he would hear his ribs pop. This happened on a weekly basis. He said he intended to hurt him.

An autopsy found Corby had 81 injuries to his tiny body including broken ribs, fractures and bruises.

Sentencing submissions are happening this morning before Justice Martin Burns.
