A 23-year-old man from South Australia has admitted shaking his infant to death because he would not sleep during night times.

Brandon Lee Harris, the man, was jailed for 3 years with a none-parole period of 18 months for the aggravated assault of his 4-year-old son Kobe in May 2018.

Little Kobe died from his injuries in August last year after being kept on life support for over 1 year.

His father was arrested in prison in South Australia and got charged with manslaughter 3 months after the incident.

Harris will be facing sentence submissions in the Supreme Court in June 2020.

The child, whose identity was not shared with the public, was rushed by Harris to an emergency room in Kadina, Yorke Peninsula, where Harris told a nurse that his son was breathing funny.

He was taken to see a doctor, who noted he was suffering from dilated pupils, irregular breathing, and a bruise to the wrist.

The infant was later admitted to the Wallaroo hospital, where he was placed on emergency neo-natal resuscitation and began suffering seizures.

The infant was transferred to the Women’s and Children’s Hospital, where a pediatrician found that he had suffered significant neurological impairment.

The responding doctor found out that Kobe had to hemorrhage, swelling, and bleeding on the brain.

This was a result of being the baby being forcefully shaken constantly.

His shocking attack at the hands of his dad left him with several critical injuries, which include brain damage, severe spastic quadriplegia, epilepsy, and even blindness.

Harris claimed at first that his son had thrown himself backward during a feed and hit his head on the arm of a chair.

Later he did admit that he shook the baby twice when he would not go to sleep during night time.

Harris, who used to work as a cleaner, also said that the shoved a bottle into the mouth of the baby because he was frustrated.

This caused an injury to the tongue, collarbone, and lip of the baby.

He pleaded guilty at the time to recklessly cause serious harm, and the court case was finalized when the baby was still alive.

Rauf Soulio, a District Court Judge, accepted that Harris was remorseful and did not mean to hurt his son.

But he said that he had failed as a parent when he was being convicted.

Our thoughts and prayers are with the infant, may his soul rest in peace.
