MURDER and torture have now been added to the list of crimes a Kin Kin father is accused of inflicting on his toddler.
Corby was just a few months shy of his second birthday when his father allegedly threw him repeatedly against a timber bed at his family home after he would not stop crying on Wednesday.
The little boy, the youngest of three children, died late Friday evening after succumbing to critical injuries.
Shane Purssell Akehurst, 33, will return to Brisbane Magistrates Court tomorrow to formally face new charges but he can only apply for bail in the Brisbane Supreme Court if he seeks to be released. Sunshine Coast detectives drove to Brisbane - where Mr Akehurst is in custody - yesterday afternoon to upgrade the charges.
Murder has replaced the grievous bodily harm charge, the torture charge is new and an extra count has been added to the original three counts of assault occasioning bodily harm.
Prosecutor Wayne Kelly told Brisbane Magistrates Court on Friday that Corby began convulsing after his dad threw him against the bed numerous times and was left on the bedroom floor.
He said the toddler's mother Kylie Woodford arrived home a short time later and called emergency services before the toddler was airlifted to Brisbane's Lady Cilento Children's Hospital.
Since then police have worked around the clock investigating the circumstances surrounding the boy's critical injuries and subsequent death.
Police will allege through medical history inquiries that the child sustained injuries over an extended period which culminated in the alleged incident on Wednesday.
The case was adjourned until May 4 but Akehurst will now return to court tomorrow.
