Mathew Riley Baxter was just six weeks old when his life support was switched off.
He suffered 17 rib fractures, fatal head injuries and haemorrhaging to the backs of his eyes.
His father, former soldier Nicholas Aaron Baxter, is on trial for murder and is accused of shaking the infant and causing his death in 2011.
Prosecutors at the Supreme Court in Townsville have alleged Mr Baxter struck or shook his baby on November 3 that year, causing severe brain and retinal bleeding.
The infant died three days later.
The court has heard evidence from neuroscientists, paediatricians, radiologists and paramedics who were the first to respond to Mr Baxter’s triple-0 call on November 3, 2011.
In his closing statement, Baxter’s defence attorney Lincoln Crowley called the prosecution’s case “science fiction or fantasy … but not a reality”.
“Nicholas Baxter did not kill his own boy … he never harmed him,” Mr Crowley said.
The defence argued the infant could have died from an underlying medical condition, to which he said “there may be no answer at all”.
Mr Crowley said the prosecution’s case presented “theories to explain the inexplicable”.
“There isn’t any hard evidence,” he said.
“Because you see blood does not equal trauma.
“Medical findings are not injuries — they are medical findings.”
‘Where are the screams down the phone?’
Crown prosecutor Nathan Crane argued the boy’s death could be “a crime of passion”, and questioned Baxter’s conduct during the triple-0 call.
“Intention need not be pre-planned … It can be formed quickly, can dissipate quickly,” Mr Crane said.
Mr Crane questioned Mr Baxter’s conduct during the triple-0 he placed.
“Where are the screams down the phone?” he said.
Mr Crane said Mr Baxter lied about Mathew having green stool for an extended period of time.
He said Mr Baxter relied on this “untruth” to make it seem like Mathew was a child who had been unwell.
The prosecutor also rubbished claims by a radiologist from the United States, Dr David Ayoub, who told the court the six-week-old suffered from a disorder known as rickets.
Mr Crane said he could not take Dr Ayoub seriously, after he claimed a child did not need Vitamin D to grow bones.
The trial continues.
